ABSTRACT
A data entry system includes a hand held data entry unit
having a reading sensor for sensing commands and/or data,
rewritable storage for storing information relating to selectable items, a controller (a microprocessor or other processing circuitry) and a display screen for displaying a user
readable representation of the commands and/or stored
information for a selected item, and a telecommunication
interface for the telephonic transmission of information
relating to a selected item or items from the storage to a
remote processing center and for the telephonic information
relating to selectable items from the remote processing
center to the storage. Preferably a telecommunications interface is provided in the hand held unit for cellular or other
wireless telephony systems. The hand held unit can be
configured to combine the data entry functions with those of
audio telephony.

HAND HELD TELECOMMUNICATIONS AND
DATA ENTRY DEVICE
wand includes a beeper for indicating the correct reading of
a bar code and the current memory loading. The wand
described in EP-A-0,094,571 is relatively simple in construction, and although it is readily portable, it does not
provide any confirmation of what has been read.
A further portable data entry terminal manufactured by
Telxon Corporation is described in an article entitled
"Telxon Corporation, Portable Data Collection and Entry
Systems" published by McGraw-Hill in 1989 and referenced
"R51-832-101 SKUIUPC Marking and Reading Equipment". The article describes various models of data entry
terminals similar to that described in UK patent GB-8-2,
202,664. Data from the terminals can be transmitted to a
remote station via various telecommunication options
including direct connect modems and acoustic couplers. The
data entry terminals have a generally rectangular format,
similar to a large scientific calculator with a rectangular
display and an array of keys. For most models, a separate bar
code reader wand is provided which is connected to the data
entry terminal via a flexible cable, requiring a two-handed
operation as described above. One model PTC-620 has the
same basic format as the other terminals, but is described as
being for simple applications and features a snap-on reversible head for one-handed operation with either the left or the
right hand. However, this terminal is still relatively bulky
and cumbersome and in use it is easy inadvertently to
operate one or more keys in the array of keys.

FIELD OF THE INVENTION
15
This invention relates to data entry systems, to applications of such data entry systems and to equipment for use
therewith.
20
BACKGROUND
UK patent GB-B-2,202,664 describes an example of an
application for a data entry system for the automated ordering of merchandisable items. Merchandisable items are
represented in a printed catalogue or other form of list and
are associated with bar codes. A merchandise ordering unit
comprises a bar code reader with a telephone transmission
capability for use in selecting one or more items from the
catalogue and transmitting electronically an order for the
merchandise to a processing centre over the public telephone
network. The orders for the merchandisable items received
in this way are processed in the processing centre. As
described, the hand held data entry terminal comprises a
calculator-like processing unit with a pen-like bar code
reader wand electrically connected to the processing unit via
a flexible cable. The processing unit includes a display for
displaying information and a telephone transmission capability for transmitting captured data via the telephone network. Although this system works well, it is rather bulky and
can be somewhat inconvenient in use as it requires two
handed operation, one hand for the processing unit and one
hand for the wand. Alternatively, if the processing unit is not
carried all the time, it needs to be located in a position where
the display on the processing unit can be seen and the keys
on the processing unit can be operated. It will be appreciated
that particularly where the processing unit is being carried in
the hand, operation of the keys on it while holding the wand
requires considerable dexterity.
European patent application EP-A-0,094,571 describes a
self-contained portable data entry terminal positioned within
a portable wand-type enclosure. The wand contains a bar
code optical reader, signal conditioning electronics, a microprocessor, a memory and a rechargeable battery. The optical
reader is operable as a transmitter/receiver so that readout of
data stored in the memory is possible. An example of the use
of the portable data terminal is described in which captured
bar code data can be output from the memory via the optical
reader to an optical receiver and from there via an audio
coupler to a telephone line for transmission to a remote
station. Another example is described where the bar code
data relates to items on a menu in a restaurant. Captured
menu selections can be output from the memory via the
optical reader to an optical receiver and from there via a
computer to a printer in a kitchen. Also described is the
programming of the portable data entry terminal using an
optical transmitter to input data via the optical reader. The

65
An object of the present invention is to provide a data
entry system which mitigates the problems of the prior art.
In accordance with an aspect of the invention, there is
provided a data entry system comprising a hand held data
entry unit, the hand held unit comprising a reading sensor for
sensing commands and/or data and for producing input
signals in response to the sensed commands and/or data,
rewritable storage for information relating to selectable
items, a controller connected to receive and process the input
signals from the sensor for responding to the commands to
control the hand held unit and/or to the data to select the item
and a display screen for displaying a user readable representation of the commands and/or stored information for the
selected item, and a telecommunications interface for telephonic transmission of information relating to a selected
item or items from the storage to a remote processing centre
and for telephonic transmission of information relating to
selectable items from the remote processing centre to the
storage.
The provision of a hand held unit having an integral
sensor, control, storage, display means with a telecommunications interface enables the unit to be used in a particularly efficient and self-contained marmer for the capture,
processing, storage, display and transmission of data. The
inclusion of the display in the hand held unit enables the user
to verify the data being captured without taking his or her
eyes off the areas in which data capture is taking place.
Preferably, the telecommunications interface is integral to
the hand held unit. The provision of a telecommunications
interface in the hand held unit enables captured data to be
used for direct telephonic transmission of the captured data
via a telephone network to a remote processing centre. It
also allows for data and/or commands to be received from
the remote data processing centre.
Preferably, the hand held unit includes a rechargeable
power source. There can be provided a base unit separate
from the hand held unit, wherein the base unit includes a
US 7,139,591 B2
3
4
charger unit and the base unit and the hand held unit are
provided with respective intercounectable electrical connectors for recharging the rechargeable power source.
In some embodiments of the invention, the data entry
system can comprise a base unit separate from the hand held
unit, wherein the base unit and the hand held unit are
provided with a wireless data link which is operable for
bidirectional data transfer between the hand held unit and
the base unit, and wherein the base unit includes a telecommunications interface for telephonic transmission of information relating to a selected item or items from the storage
to a remote processing centre and for telephonic transmission of information relating to selectable items from the
remote processing centre to the storage. In this embodiment,
the wireless data link preferably comprises, in the base unit
and the hand held unit, optical transmitters and/or receivers
which cooperate when the hand held unit is in the rest
position to provide a two way optical data link for transferring data from the hand held unit to the base unit and/or from
the base unit to the hand held unit. In other embodiments it
could comprise respective radio frequency, rather than optical, transmitters and receivers, or indeed other types of
transmitters and receivers.
In preferred embodiments of the invention, the telecommunications interface is an interface for connection to a
wireless telephony network. This provides for a particularly
advantageous implementation of the invention, which can
then be used without the need to plug in the data entry
system to, for example, a conventional wired telephone
network.
In a preferred embodiment of the invention the telecommunications interface is a cellular telephone network interface. In this embodiment of the invention, particularly where
the telecommunications interface is incorporated in the hand
held unit, the data entry system can be used with the
convenience, for example, of a portable cellular phone.
Cellular telephone networks are now common place and
give a very wide area of coverage. This facilitates the use of
a data entry system in accordance with the invention in, for
example, a user's home or workplace.
Alternatively, the telecommunications interface can be a
satellite telephone network interface, or some other form of
wireless telephone interface, for example a telephone interface for a telephone network based on highly localised
transponder stations.
Where the telecommunications interface is intended to
interface with an analogue telephone network, the telecommunications interface includes a modem.
By arranging that the reading sensor can be used for the
input of commands for controlling the hand held unit, the
number of user input means (e.g., keys) can be kept to a
minimum, reducing the possibility of inadvertent operation.
Preferably, there are provided one or two manually operable
switches for scrolling the display in a first and/or second
direction for selectively displaying a plurality of data stored
in the storage. The scrolling of the display enables a large
number of items to be accessed with a relatively compact
display. In a preferred embodiment of the invention, the first
and/or second switches are the only switches on the hand
held unit. Preferably also, operation of the first and/or
second switches in predetermined operational states of the
hand held unit causes predetermined functions other than
scrolling functions to be performed (e.g., powering-up or
powering-down of the hand held unit). By the provision of
only two keys on the hand held unit, the possibility of
accidentally operating an incorrect key can be reduced, and
also the hand held unit can be kept particularly compact.
Preferably, the hand held unit comprises a sensor for
reading coded data, the controller being arranged to access
the stored information for selectable items to determine
natural language characters or images corresponding to the
coded data for display. The invention finds particular, but not
exclusive application to the reading of bar codes and/or
binary dot codes, whereby the sensor is a bar code and/or dot
code reader. It will be appreciated that the invention also
applies to other forms of codes.
The hand held data entry unit may comprise a reading
head including a reading sensor for producing input signals,
wherein the reading sensor traces movements of the reading
head and wherein the controller is responsive to signals from
the sensor representative of the movements for identifying
characters traced by the reading head as captured data. In
this manner data entry can be made in an advantageous
manner by tracing out the characters of the data to be input
or characters representing commands for controlling the
operation of the data entry system.
Preferably, the controller is user programmable to cause
the captured data to be displayed on the display either in a
first orientation suitable for reading displayed data when the
hand held unit is held in a user's right hand, or in a second
orientation suitable for reading displayed data when the
hand held unit is held in a user's left hand. In a preferred
embodiment the display has a substantially rectangular
display screen with a longitudinal axis arranged substantially parallel to a longitudinal axis of the hand held unit. For
example, for right handed operation, a string of characters
could, for example, be displayed along the display from an
end nearest to the sensor to the end furthest therefrom,
whereas for left handed operation, the same string of characters would be displayed from the end of the display
furthest from the sensor to the end nearest thereto.
A data entry system comprising a hand held unit with or
without a base unit as described above, can also include
means for displaying a plurality of selectable items with
associated data sources for user selection of an item by
operation of the hand held unit and a remote processing
centre for processing user selections transmitted from the
hand held unit. The controller in the hand held unit is
preferably arranged to respond to appropriate commands
input, for example via the reading sensor, to issue coded
instructions via the telecommunications interface to the data
processing centre and to receive programming data (e.g.,
relating to information for selectable items) from the programming centre for storage in the hand held unit.
The data entry system may additionally be arranged to
provide the functions of a telephone to permit audio communication. In particular, if a cellular telephone interface is
provided in a hand held unit, this unit can advantageously
combine the functions of the data entry unit and a cellular
telephone.
Accordingly, the invention also provides a data entry
system additionally comprising means for displaying a plurality of selectable items with associated data sources for
user selection of an item by operation of the hand held unit
and a remote processing centre for processing user selections transmitted from the hand held unit. Preferably, the
hand held unit is programmable remotely from the processing centre.
In a preferred embodiment of the invention, the hand held
unit is configured as an elongate unit such that it may be held
by a user in the manner of a pen or quill with the reading
sensor being located in a reading head at or adjacent to one
end of the hand held unit. The configuration of the hand held
unit such that it may be held in the marmer of a pen or quill

means that the unit can be held in a familiar and comfortable
manner. Also, it facilitates the provision of user input means
(e.g. switches) on the hand held unit to be located such that
inadvertent operation thereof can easily be avoided.
Preferably the reading sensor is located in a reading head
which is releasably attached to the hand held unit. This
enables alternative types of reading head to be connected to
the hand held unit and/or for faulty reading heads to be
replaced easily.
The invention also provides a merchandising system
comprising a data entry system of this type wherein the
selectable items are merchandisable items and the remote
processing centre initiates processing of user orders of the
selectable merchandisable items.
Thus, a data entry system in accordance with the invention, especially a data entry system comprising a hand held
unit including a telecommunications interface for use with a
wireless telephony system, such as a cellular network telephone system, provides a particularly advantageous device
for use, for example, for "home shopping". It enables the
user to make shopping selections from a catalogue or from
a series of options displayed on a television screen from the
comfort of his or her home without the need to connect the
device to a conventional telephone network. A hand held
unit including a wireless telephone network interface such as
a cellular network interface finds particular application
where the user of the system is travelling from place to place
and may need to perform data entry functions when they are
far from a conventional wired telephone network socket.
A data entry system or a merchandising system as
described above preferably includes a verification device in
the form of a verification card (e.g., a credit, payment or
other validation card) or like carrier carrying a verification
bar code and/or dot code for verification of a user identity.
Operation of the data entry system subsequent to an initial
data capture operation can then be made dependent on the
identification of authorised coded data.
The invention also provides a carrier for a plurality of data
and/or command codes (e.g., bar and/or dot codes) for
association with means for displaying a plurality of selectable items in a data entry system or a merchandising system
as defined above, wherein the carrier carries a plurality of
codes, each for a respective one of a plurality of natural
language and/or numeric characters, and a plurality of
commands for controlling the operation of the data entry or
merchandising system, each code being associated with a
visual representation of the corresponding natural language
or numeric character or command and/or of a graphical
representation thereof. This avoids the need for a complete
coded data source to be associated with each selectable item
in, for example, a catalogue, rather a composite code can be
built up by capturing a desired sequence of individual codes.
By including the command characters as well, the need for
a lot of keys on the data entry device can be avoided.
As an alternative to the use of bar codes, other data
representations could be used. Indeed, if the data entry
device is provided with a reading sensor in the form of a
camera or other scanning sensor rather than a bar code
reader, and the data entry device is provided with character
or image recognition logic, graphical or alphanumeric data
representations can be captured directly. One application of
an embodiment of the pen with a camera head as its sensor
could be for fingerprint recognition.
As an example of a possible mode of operation, a command character (e.g., a bar code) can be read using the
reading head (e.g., a bar code reading head) and this can be
used to load down remote data from a remote station. This
is particularly advantageous mode of operation where the
data entry system can set up a telephone connection to the
remote station automatically, for example where the data
entry device has cellular telephone capabilities.
The carrier is preferably in the form of a sheet of material.
The various characters and commands could be arranged in
the manner of a standard typewriter keyboard layout to
facilitate entry of individual codes to make up a desired code
sequence (e.g., for a specific product code).

conventional, if rather thicker than usual, pen.
The pen 10 has an elongate body 12 with, in the present
example, external dimensions of approximately 120 mm by
40 mm, although the dimensions may be larger or smaller as
desired subject to technical limitations. A reading head 14,
for example a red or infra-red optical reading head (e.g., a
US 7,139,591 B2
7
8
laser diode) suitable for reading bar codes is located at one
end of the pen. Other types of reading head may be provided.
The reading head is preferably-replaceable for interchanging
types of reading head. A removable battery cover 16 covering a battery compartment is located at the other end of the
pen. As an alternative to a compartment for removable
batteries, a removable and/or fixed rechargeable battery
pack could be provided instead. Also, the reading head in the
present embodiment is arranged to read with a reading angle
of between oo to 45° to the normal to the bar code to be read.
On the upper surface of the pen shown in FIG. lA a
display screen 20, first and second microswitches 22 and 24,
a first indicator light 26 and a second indicator light 28 are
located. The display screen 20 preferably comprises a conventional two-dimensional array of pixels which can be
selectively activated in order to provide the display of a wide
range of displayable items. However, in a low cost version
of the pen 10, the display may be configured only to display
a predetermined range of characters and symbols, this reducing the complexity of the display and the controlling logic
and thus reducing the cost as will be well understood by one
skilled in the art.
Any suitable display technology can be used which
enables the displayed information to be read over a wide
enough angular range such that it can be read by the user
when the pen is held at an angle suitable for reading a bar
code. In this way it is not necessary to change the orientation
of the pen in order to read the display. In view of the low
power consumption and advantageous readability characteristics, a 2 line by 16 character supertwist LCD display screen
is employed in the preferred embodiment giving a viewing
area of approximately 60 mm by 16 mm with a character
size of approximately 3 mm by 5.5 mm. The display is
preferably located towards the end of the pen 10 opposite to
the reading head 14 with its longitudinal axis substantially
parallel to the longitudinal axis of the pen 10.
With the pen 10 held between thumb and forefinger with
the user's hand below the pen as viewed in FIG. lA, and
with the pen held at an angle of, say, 30" to the normal of a
bar code to be read, (assuming that the normal to the bar
code is generally in the direction of the line of sight of the
user), the display screen can be read without difficulty.
The switches 22 and 24 are used to control basic operations of the data entry system and for control of the sequential display of stored information (scrolling of the display) as
will be explained later. The indicator light 26 is used to
report successful scarming of a bar code. The indicator light
28 is used when rechargeable batteries (70, FIG. 3) are
inserted in the battery compartment to indicate that the
batteries are charging.
On the lower surface of the pen 10 shown in FIG. lB, an
optical transmitter 32 and an optical receiver 34 are provided
in a shallow recess 33. Also, provided on the lower surface
are a locating groove 36 and first and second electrical
contacts 30 and 31. The optical transmitter 32 and the optical
receiver 34 are used in combination with an optical receiver
62 and optical transmitter 64, respectively, on a base unit 40
to be described with reference to FIG. 2, for the transfer of
data between the pen 10 and the base unit 40. The locating
groove 36 is used correctly to position the pen 10 with
respect to a corresponding ridge in a cradle 56 on the base
unit 40 when the pen 10 is placed in that cradle 56. The
cradle 56 defines a rest position for the pen 10 on the base
unit 40. The first and second contacts 30 and 31 are arranged
to cooperate with corresponding contacts 60 and 61 in the
cradle 56 on the base unit 40 for charging the rechargeable
batteries.
Turning now to FIG. 2, this illustrates a plan view of a
base unit 40 for use with the pen 10 of FIGS. lA and lB.
The base unit includes a generally rectangular housing 42
with a raised portion 44 containing a power supply unit (102,
FIG. 4) which receives electrical power via a mains supply
cable 45 and a mains switch 46. The mains switch 46 is
located on the right hand side of the base unit housing 42.
Cooling slots 47 for the power supply unit (102, FIG. 4) are
provided in the upper surface of the raised portion 44.
Further slots 48 in the upper surface of the base unit housing
42 are located over a speaker (110, FIG. 4) for relaying
information to the user of the data entry system. The rear of
the housing 42 is also provided with a socket 52 for a
standard telephone plug for connecting the base unit 40 to a
telephone line 50 and a standard serial connector 54 (e.g., an
RS232 connector) for connecting the base unit to, for
example, a personal computer (not shown). A manual switch
53 can be provided for switching between the telephone line
and the serial connector. It will be appreciated that a parallel
connector could be provided instead of, or in addition to, the
serial connector 54. A separate telephone socket 55 can be
provided for the connection of a standard telephone handset
to the base unit.
Towards the front of the base unit housing 42, a recess is
formed which is configured as a cradle 56 for receiving the
pen 10.
An optical receiver 62 and an optical transmitter 64 are
located in the bottom of the recess for cooperating with the
optical transmitter 32 and optical receiver 34, respectively,
when the pen is located in the cradle 56. The optical receiver
62 and the optical transmitter 64 are surrounded by a wall 63
which also forms a shroud between the optical receiver 62
and the optical transmitter 64. The wall 63 cooperates with
the recess 33 in the pen 10 to prevent external light reaching
the optical link, and the shroud between the optical receiver
62 and the optical transmitter 64 prevents light from the two
optical paths between the pen and the base unit and between
the base unit and the pen from interfering with each other.
It will be appreciated that alternative configurations are
possible, for example the wall could be provided on the pen
and the recess on the base unit, although this could mean that
the pen was less comfortable to use.
First and second base contacts 60 and 61 are also located
in the recess for cooperating with the contacts 30 and 31 on
the pen 10 when it is inserted in the cradle 56, thus enabling
rechargeable batteries (70, FIG. 3) in the pen 10 to be
recharged. A locating ridge 58 is formed in the recess for
cooperating with the locating groove 36 in the bottom of the
pen 10 to enable to pen to be positioned correctly in the
cradle 56 such that the optical transmitter/receiver pairs
32/62 and 64/34 and the contact pairs 30/60 and 31/61 are
aligned correctly.
The pen 10 can also be provided with a socket for directly
charging the internal rechargeable batteries using an AC
mains supply or a DC supply. In the first case the pen will
include a transformer, in the second a transformer/rectifier
could be incorporated in, for example, a mains plug.
On a further raised portion 66, one or two base unit
indicator lights are provided. The first base unit indicator
light 67 is for indicating the base unit is receiving mains
power and is turned on. Optionally, the second base unit
indicator light 68 can used to indicate that rechargeable
battery (70, FIG. 3) in the pen is being charged.
FIG. 3 is a schematic block diagram of the functional
elements of the pen 10. A processor 74 is preferably formed
by a conventional progrmable microprocessor (e.g., an
Intel 80C31 12 MHz CMOS microprocessor with two

internal clocks, an Intel 80486, etc.), although a special
purpose or specially configured unit (e.g. an ASIC) could
alternatively be used (compare FIG. 10). A read only
memory (ROM) 76 is connected via a bus 84 to the
processor 74 for the storage of control programs and data.
The ROM 76 can be implemented by any appropriate
technology, for example by a flash PROM. A random access
memory (RAM) 78 (for example a 128K low power static
RAM, or higher capacity RAM, e.g, a 256K, 512K ... 5 Mb,
etc., RAM) is connected to the processor via the bus 84. The
RAM 78 is used as working storage and for the storage of
data captured using the reading head 14. A display interface
80, which connects the display 20 to the bus 84, responds to
display instructions from the processor to drive the display
in a conventional manner. An optical interface 86 is connected to the bus to convert data to be transmitted into
signals for driving the optical transmitter 32, and converts
signals from the optical receiver 34 into data to be passed to
the bus 84.
In the present embodiment, other connections are made
directly to the processor rather than via the bus. Thus, in the
present embodiment, signals relating to data captured by the
reader head 14 are passed directly to the processor 74 to be
processed.
The manual switch 22 is also connected directly to the
processor. In use this switch serves as a "scroll-down" key.
The second manual switch 24, which in use serves as a
"scroll-up" key, is, however, connected to the processor via
a power control module (PCM) 72. This is because the
switch 24 also serves as a "power-up" key for turning the
pen on or powering it up after it has been powered down.
The power control module 72 responds to operation of the
key 24 in a powered down state to connect the battery 70 to
the processor 74. The power control module 72 also controls
the charging of the battery 70 when the contacts 30 and 31
are connected to the corresponding contacts 60 and 61 in the
cradle 56 of the base unit 40. The indicator light 67 (e.g., an
LED or NEON) is connected to the processor 74 and
indicates when the base nnit is connected to the mains. The
optional indicator light 68 (e.g., an LED or NEON) is
connected to the power control module 72 to indicate when
the battery 70 is being charged.
The processor is progrannned by means of control programs and data stored in the ROM 76 and, in use, in the
RAM 78, to receive signals from the reading head 14, to
interpret those signals and to derive data therefrom which
are displayed on the display 20 and stored in the RAM 78 for
subsequent transmission via the optical interface as will be
described in more detail below.
FIG. 4 is a schematic block diagram of the functional
elements of the base unit 40 of FIG. 2. A power supply
module 102 is connected to a mains supply via the switch 46
and the supply cable 45. The power supply unit 102 is also
connected to the contacts 60 and 61 so that, when the pen 10
is located in the cradle 56, the battery 70 can be recharged.
The power supply unit 102 also supplies power to the other
elements of the base unit via supply lines which are represented schematically (for reasons of drawing simplicity) by
the arrows 104.
A modem 100 is connected via an optical link 106 to an
optical receiver 62 and an optical transmitter 64. The optical
interface 106 converts signals from the optical receiver 62 to
data to be passed to the modem 100 and converts data from
the modem 100 to signals to be transmitted by the optical
transmitter 64. A further interface (e.g. a standard V24/
RS232 interface-not shown) for connection to a personal
computer (not shown) could also be provided. Also a socket
for a connection to a standard telephone handset (not shown)
could be provided. The modem 100 can be a conventional
modem generally comprising a master control unit 112, a
data pump 114 and memory 118. The master control unit 112
is connected to receive data from the optical interface 106
(and/or from a V24/RS232 interface, if a personal computer
is connected). Data from the data pump 114 are coupled via
a line interface 116 to the telephone line 50. The data pump
116 is also connected via an audio interface 120 to a speaker
110 for monitoring the transmission of data via the telephone
line 50.
FIG. 5 is a schematic representation of a data entry
network comprising a plurality of pens/base nnits 10/40
connected via respective telephone connections 50 (telephone lines, wireless telephone charmels, etc) to a processing centre 108 where data transmitted from the individual
pens/base units 10/40 are processed. In the preferred
embodiment of the invention, the pens/base units 10/40 are
used for the placing of orders for merchandise and the
processing centre 108 processes those orders and dispatches
them to the users.
FIG. 6 is a schematic representation of an example of a
control card for use with the pen 10. The card shows bar
codes for the numerals 0 to 9 and for a set of commands. The
command bar codes are used for controlling the operation of
the pen 10. The control card can be thought of as a keyboard
extension for the pen 10.
At this point it should be explained that the operation of
reading a bar code is performed by the processor 7 4 in a
conventional manner. Thus, where the head 14 comprises a
red or infra-red light source and a light sensor, signals
representing changing levels of reflected illuminations are
supplied to the processor 74. Firmware stored in the ROM
76, or in other embodiments possibly hard-wired in the
processor 74, is used then to decode the changing levels of
reflected illumination to generate a numerical value. On
successful reading of a bar code the good read light 26 is
illuminated.
The processor tests the numerical values to determine
whether the sensed code relates to data or a command. A
look up table containing the numerical values for individual
commands (not shown) is configured in the ROM 76 and/or
RAM 78. By accessing this table, input commands can be
identified. The controlling software is aware of which commands can be executed for the current processing state. On
identifying a currently executable command, the processor
74 executes that command and causes the display of a
human readable command description for user verification
purposes. The processor causes an error message to be
displayed on the display screen if a non-executable command (e.g., a command has been input at a wrong time) has
been input.
If the code does not relate to a recognised command, it is
treated as data. The data are then stored in RAM as the result
of reading a bar code and are used to address a description
of the item referenced by the bar code value from a further
look-up table. If a description of the item corresponding to
the bar code value is stored in the ROM 76 and/or the RAM
78 in a suitable data structure so that the bar code value can
be used either directly or indirectly to address the appropriate description, then the item description can readily be
displayed instead of or as well as the bar code value for user
verification purposes. If the bar code is not read correctly,
then an error message is displayed on the display screen.
The item description data can relate, for example, to items
from a merchandising catalogue. In the this case the rewritable storage capacity of the pen (e.g. the RAM 78) is chosen

to be sufficient to store all the items from one or more
merchandising catalogues. If the data is stored in volatile
memory, this data is downloaded from the remote processing
centre via the telecommunications link on restoring power to
the memory in the pen. Preferably, if volatile memory is
used, power is supplied to the memory even when the pen
is "switched off'. An integral rechargeable back-up battery
can be provided in addition to the battery 70 to maintain
power to a volatile memory when the battery 70 is being
changed. If non-volatile memory is provided, then this data
can be retained during a period when no power is supplied
to the memory. However, through the use of rewritable
memory and control logic enabling the memory to be
updated using data downloaded from the remote processing
centre, it is possible to keep the pen's memory up to date on
a full list of merchandisable items, including product
description, availability, price, etc. Then on reading a bar
code relating to an item stored in memory the display on the
pen can indicate a description of the item corresponding to
the code read, its availability and price. If the code read is
not recognised, for example, the pen can be programmed
automatically to call up the remote processing centre to
check on whether an update of the pen's storage is needed
when the pen is replaced in the base unit.
FIG. 7 is a flow diagram illustrating an example of a
possible series of operations using an example of data entry
system such as that described with reference to FIGS. 1 to
6. It will be appreciated that other sequences and modes of
operation may be provided in other embodiments of the
invention.
In a first step, S1, the pen 10 is removed from the base unit
40.
In step S2, "Up" key switch 24 is operated. The power
control module senses operation of this key switch and
powers up the processor 74, which performs a series of
diagnostic checks, calibrates itself and then displays an
initial message (e.g., "Ready") on the display 20.
In step S3 the "Down" and "Up" scroll keys switches 22
and 24 are operated to scroll though a number of initial
options pre-stored within the ROM 76 or the RAM 78 and
presented on successive screens of data items on the display
20.
In this example of operation, in step S4, when an option
"Left-handed operation" is encountered on the screen, the
pen is scanned over the "Enter" command bar code on the
command sheet of FIG. 6. Whereas for right-handed operation, where text is displayed in English, the text is displayed
in sequence from the end of the display nearest to the
reading head 14 towards the opposite end, for left-handed
operation the text display is inverted with the text then
reading from the end of the display furthest from the reading
head to the end nearest thereto. It can be seen, therefore, that
the text is displayed in an orientation appropriate for the
user. If left-handed operation has already selected and it is
desired to use the pen in a right-handed mode, then "Righthanded operation" can be selected by scrolling the display
using the "Down" and "Up" key switches 22 and 24 and then
scanning the "Enter" command bar code when the appropriate option is displayed.
Other options which could be provided in this mauner
could, for example, be the selected of one of a number of
operating languages.
In step SS, the scroll key switches 22 and 24 are again
operated until the option "Ready" is encountered once more.
Then a series of merchandise selections can be entered by
the user by scanning the bar codes for the desired merchandise selections and the command bar codes "Enter", "Clear",
"Quantity", etc., as appropriate. As each bar code is scanned
successfully, the good read indicator 26 lights and the data
read by the bar code reader is displayed on the screen. Either
the alphanumeric value of the bar code read is displayed or,
if a description of the item corresponding to the bar code
value is stored in the RAM or the ROM, then this can be
displayed instead of or as well as the bar code value.
Step SS can be repeated as often as desired until all the
desired items have been entered, or until the RAM 78 has
become full or nearly full, in which case a "Memory full"
error message is displayed on the display screen 20.
If desired, the items entered and stored in the RAM 78
could be checked by selecting a "Check Entries" option with
the scroll key switches 22 and 24. In this case the items
entered can then be checked in sequence using the scroll key
switches 22 and 24, and if necessary corrected by scanning
the correct command bar code while the appropriate item is
displayed.
In the example shown in FIG. 6, however, after entering
the desired items, a phone number is then entered in step S6
by scanning the command bar code "Phone" followed by the
number of the processing centre 108 to be called. As an
alternative to entering separately the telephone number, this
could be pre-stored in memory, or could alternatively be
included in the "Phone" bar code.
After this, in step S7 the pen is placed in the cradle on the
base unit and the "Down" key switch 22 is pressed to
download the data from the pen. This causes the data for the
telephone number to be downloaded to the modem 100 via
the optical link 106. The downloading of the telephone
number causes the base unit automatically to call the desired
number and, once the normal modem handshaking is completed, to transfer the data stored in the RAM 78 in the pen
10. Preferably, in addition to the actual data stored, the
processor 74 in the pen 10 automatically adds error correcting codes to enable the processing centre 108 to verifY that
successful transmission has occurred. The processing centre
108 then sends a message to confirm (or otherwise) whether
successful transmission occurred after checking the error
correcting codes. This message is then displayed on the
display 20 of the pen 10.
It will be appreciated that the steps S1 to S7 illustrated
above merely form one possible method of operation. In an
alternative embodiment of the invention, the scrolling function is only used for stepping though items which have
already been entered into the pen, whether in the form of
selectable items downloaded from the remote processing
centre and/or items selected by means of the reading head.
All other command functions are input by reading appropriate command codes from a command sheet. For this
embodiment therefore, a command sheet should include
commands for left and right handed operation, or a command for changing handedness. Then, to change between
left and right-handed operation, it is merely necessary to
scan an appropriate command bar code.
In a final step (not shown in FIG. 7). the pen is turned off
by pressing the "Down" and "Up" scroll key switches
simultaneously. It should be noted that the processor, which
is provided with a date and time clock, is arranged to
power-down the pen to conserve battery power if no bar
codes are scanned and no key switches operated during a
predetermined interval (e.g. 30 seconds). However, as mentioned above, power will be maintained to the RAM 76 if
this is a non-volatile memory.
The software stored in the pen also permits the loading of
data from the processing centre or another remote computer.
The programming is performed using a series of commands

preceded by dot codes. The programming commands are
thus known as "dot" commands and cover operations such
as RAM PEEK, RAM POKE, ROM PEEK, DISPLAY,
SENSE, GET INFO, GET FIRST ITEM, GET NEXT ITEM,
GET PREVIOUS ITEM, AMEND ITEM, DELETE ITEM,
CLEAR ORDER, CLEAR CATALOGUE, ADD CATALOGUE ITEM, and AMEND CATALOGUE ITEM. In this
way, a significant amount of catalogue data and/or program
software can be held in the processing centre and be sent to
the pens only when required. Where programs are to be
downloaded, rewritable program storage will be needed in
the pen, for example by implementing the ROM 76 in flash
PROM technology.
The processing centre can also send commands to a hand
held unit to instruct the user to scan in a personal identification number (PIN) possibly with the scanning of a further
verification number from, for example a verification device
in the form of a verification card (e.g., a credit, payment or
other validation card) or like carrier carrying a verification
bar code and/or dot code for verification of a user identity.
Alternatively, the verification device can be scanned prior to
any connection to a remote processing centre. In this case a
connection can then be made to the remote processing centre
for verification of the user identity. Operation of the data
entry system subsequent to an initial data capture operation
can then be made dependent on the identification of authorised coded data and a PIN number.
FIG. 8 illustrates another example of a pen 10 in accordance with the invention. This example is substantially the
same as the pen 10 described with reference to FIGS. 1 and
3, apart from the addition of a touch sensitive screen 90 for
the display 20. A touch screen interface 88 couples the touch
sensitive screen to the bus 84 so that data sensed by the touch
sensitive screen can be communicated to the processor 74.
Although FIG. 8 shows a touch sensitive screen 90 (e.g., an
overlay) separate from a conventional display screen, any
applicable touch sensitive screen technology can be used,
either though the use of an addition to an existing conventional display screen, or the use of a display screen with
integral touch sensitivity. One or more touch sensitive areas
can be defined on the touch sensitive screen area, in combination with the data displayed on the display screen, for
the entry of commands and/or the selection of displayed
items. In particular, the processor 74 can be arranged to
display a menu of user selectable items and to be responsive
to a location at which the screen is touched for input of a user
selection of a menu item. The touch sensitive screen can then
thus be used as a dynamic and reconfigurable user interface.
Touch screen entry can be used in place of or in addition to
the entry of commands by scanning the bar codes on the
command bar code card.
FIG. 9 illustrates another example of a pen 10 in accordance with the invention. This example includes much in
common with the pen 10 of FIG. 3, except that here a
modem 92, a socket 94 for a standard telephone plug and a
speaker 95 for monitoring transmissions during operation of
the modem are provided in place of the optical interface 86
and optical transmitter and receivers 32 and 34. In this
example, therefore, data can be transmitted and received via
a telephone line without the use of the base station, providing added portability. Preferably, a simplified base station is
provided in the form of a charging unit for rechargeable
batteries in the pen 10. It will be appreciated that the pen 10
could also be provided with the touch screen facility of the
pen 10 of FIG. 8.
Although in the above embodiments, the pens 10 are
intended for manual scanning of bar codes, it will be
appreciated that they could also be used for reading other
optically readable codes, such as binary dot codes, by the
provision of appropriate control software for progrannning
the processor 74. Alternatively, in place of the sensor head
14 which is intended to be manually scanned, a selfscanning head could be provided.
The invention is also applicable to the reading of other
coded data sources such as, for example, magnetic strips,
graphical representations and/or alphanumeric characters,
by the provision of an appropriate reading head and control
logic.
Alternative removable heads could be attached to the tip
of the pen by a screw, bayonet, friction or other appropriate
attachment arrangement.
For example, the data entry pen could be provided with a
reading head which is responsive to movement of the pen for
tracing out desired codes and or commands. In particular, by
the provision of a rolling ball in a holder in the reading head,
of rotation sensing means in the manner of a personal
computer mouse for tracing movements of the ball and
suitable interpretation logic in software or special purpose
hardware, for defining a series of vectors as the pen is moved
over a surface and for performing pattern recognition on the
resulting vector patterns to identify control and/or alphanumeric characters traced out by the pen head, it is possible
directly to input information into the pen by "writing" down
those characters. By limiting the range of characters to be
recognised (e.g., corresponding to the numerals and commands shown in FIG. 6) it is possible to use conventional
pattern recognition techniques with relatively limited processing power and storage requirements. It will be appreciated that increased processing power and storage can be
provided in the pen described above for the embodiments of
FIGS. 1, 3, 8 and 9 by the use of a more powerful processor
and increased memory capacity.
FIG. 10 illustrates a further embodiment of the invention.
This further embodiment of the invention is similar to the
embodiment of FIG. 9, but this embodiment is intended for
use with a wireless data transmission means, for example
radio signals. In particular, the embodiment of FIG. 10 is
intended for use with a cellular telephone network, although
it could be adapted for use with some other form of wireless
telephone system, for example a satellite based telephone
network.
The embodiment of FIG. 10 is intended to be used
independently of a base unit and to contain all the necessary
functionality for independent operation. In one alternative
the hand held unit is provided with a rechargeable battery
pack 70, which can be removed from the hand held unit for
recharging. In another alternative the hand held nnit is
provided with a fixed rechargeable battery pack 70. In the
latter alternative, and optionally in the former alternative, a
mains voltage charging socket and transformer/rectifier can
be provided in the hand held unit or the battery pack for
receiving a mains lead for charging purposes rather than the
low voltage connectors 30/31. The low voltage DC charging
connectors 30/31 can be configured in a socket for receiving
an adapter lead, with a transformer/rectifier being provided,
possibly incorporated in a plug, for connection to a mains
socket. It will be appreciated that an adapter for connection
to, for example, a 12 volt DC supply from a car may also be
provided. As a further alternative, contactless recharging
(for example by magnetic induction) could be employed.
The embodiment of FIG. 10 is implemented using a
ASIC, although a conventional microprocessor and external
hardware could be used. Likewise, it will be appreciated that

codes are indicated, if desired a set of bar codes for the
complete alphabet could be provided. Alternative arrangements of the codes would also be possible, for example a
complete set of codes and corresponding characters could be
arranged in the format of a standard typewriter keyboard
layout. The codes could also be incorporated in the letters
and numerals, for example extending as a strip across the
letters and numerals. For example, a bar code could replace
the cross bar in a capital "A", and similar modifications for
the other letters of the alphabet.
Also, as mentioned above, in appropriate embodiments of
the invention, codes other than bar codes or dot codes could
be used. For example a symbol blob code could be used, this
requiring about 1 Kbyte of storage for decoding purposes.
Indeed, in other embodiments of the invention full character
recognition (OCR) could be employed where the reading
sensor is in the form of a camera or other scanning sensor
incorporated in the reading head. With a camera and appropriate recognition logic, the pen could be used, for example,
for fingerprint recognition, either as an aim in itself, or for
user validation purposes.
In a merchandising system, where bar codes or other
codes are associated with merchandisable items, this could
be achieved simply by means of a printed catalogue, or some
other form of list, or as a result of codes applied to examples
of the products in question, or as a result of codes displayed,
for example, on a TV screen with images relating to those
products. The only requirement is that the display of the
codes are readable by the data entry system of the present
invention.
Features from the respective embodiments of the invention described above could also be combined as desired to
provide a configuration appropriate for a particular application.
Thus, for example, the audio telephony functions
described with reference to the embodiment of FIGS. 10 to
12 could be incorporated in the hand held or base unit, as
appropriate, of the other embodiments of the invention.
Although in the specific embodiments described above
the telecommunications interface for the telephonic transmission of information is only provided in a hand held unit
where no base unit with a telecommunications interface is
provided, it will be appreciated that a hand held unit with a
telecommunications interface could be combined with a
base unit also having a telecommunications interface, either
of the same or a different type.
The invention claimed is:
1. A data entry system comprising a hand held data entry
unit, said hand held unit comprising:
a reading sensor for sensing commands and/or data and
for producing input signals in response to said sensed
commands and/or data;
rewritable storage programmable with information relating to selectable items;
a controller connected to receive and process said input
signals from said sensor, said controller being arranged
to respond to said commands to control said hand held
unit and to said data to select a said item;
a display screen for displaying a user readable representation of said commands and displaying information
relating to said item from said rewritable storage;
a telecommunications interface for telephonic transmission of information relating to a selected item or items
from said storage to a remote processing center via a
telecommunications network and for telephonic reception of information relating to said selectable items
from said remote processing center to said storage via
Although specific embodiments of the invention have
been described hereinabove, it will be appreciated that many
modifications and/or additions are possible within the scope
of the present invention.
Thus, for example, although in the presently preferred
embodiments described above the hand held unit is configured with the shape of a pen, it will be appreciated that the
hand held unit could be configured in other shapes as desired
in other applications, for example in the shape of a pistol.
Although in the examples of the pen and base unit
described with reference to FIG. 1 to 4 and 8 an optical link
between the pen and the base unit is provided, in an
alternative embodiment other wireless data transmission
means, for example radio signals, could be used, in the
manner of a portable telephone of the type with a portable
handset and a base unit.
The data from the memory of the pen (e.g., the complete
list of items which could be ordered from a catalogue) could
conveniently be output in alphanumeric form via a modem
to a facsimile (fax) machine for printing the content of the
memory.
In the preferred embodiments described above, catalogue
data is down-loaded into the pen from a remote processing
system by telephone, over the telecommunications interface.
However, as an alternative to down-loading, for example a
complete catalogue, via the telephone line, other data entry
means could be provided for the bulk of the data, the
telephone line then only being used for updating the stored
data. For example the pen and/or the base unit as appropriate
could be provided with a socket or connector or reader for
a memory device (such as a plug-in ROM, a smart card,
etc.).
Although no speaker is illustrated in the examples of the
pen described with reference to FIGS. 3 and 8, a speaker or
other sound generator could be provided as in the FIGS. 9
and 10 embodiments for giving audio feedback to report on
the correct reading, or otherwise, of a code. Thus, for
example, when a code is correctly read, one beep can be
sounded, and when a code is incorrectly read, two beeps
could be sounded. Alternatively, appropriate synthetic or
recorded voice messages could be output.
Although in the examples described above the plane of
the display in generally parallel to the axis of the pen, the
plane of the display 20 could be arranged to slope progressively towards the axis of the pen away from the head end
of the pen to reduce the angle between the normal to the
plane of the display and the line of sight of the user.
Also, although in the present examples two mechanical
key switches are provided, in other embodiments one key
switch only could be provided. Operating that key switch a
predetermined number of times within a short period could
be used to emulate the provision of two key switches for
scrolling and other functions. More key switches could also
be provided in other embodiments. For example, a numerical keypad could be provided. However, in preferred
embodiments of the invention, the number of keys should be
kept as low as possible for any particular application. As in
the embodiments described above, two key switches are
preferred. The control sheet or data carrier effectively forms
a keyboard extension for the pen.
