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.

DATA ENTRY SYSTEMS

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 "R51832-101 SKUIUPC Marking and Reading Equipment". The
article describes various models of data entry terminals similarto 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 ofkeys. 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.
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 manner 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
charger unit and the base unit and the hand held unit are
provided with respective interconnectable 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

CROSS REFERENCE TO RELATED
APPLICATIONS
This application is a continuation of U.S. patent application Ser. No. 11/515,152, filed on Aug. 31,2006, now U.S.
Pat. No. 7,505,785, which is a continuation of U.S. patent
application Ser. No. 10/869,215, filed on Jun. 15, 2004 (now
U.S. Pat. No. 7,139,591), which is a continuation of U.S.
patent application Ser. No. 09/548,565, filed on Apr. 13,2000
(now abandoned), which is a continuation of U.S. patent
application Ser. No. 08/619,682, filed on May 23, 1996 (now
U.S. Pat. No. 6,058,304), filed as a 371 national stage application of international application No. PCT/GB94/02101,
filed on Sep. 27, 1994, which claims priority to GB
9321133.2, filed on Oct. 13, 1993, each of which is hereby
incorporated by reference in their entirety.
This invention relates to data entry systems, to applications
of such data entry systems and to equipment for use therewith.
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 progrming of
the portable data entry terminal using an optical transmitter to
input data via the optical reader. The 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

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 poweringdown of the handheld unit). By the provision of only two keys
on the handheld 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 systern 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 manner 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 nnit 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 fnnctions 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 scarming 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 marmer 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).

FIGS. 1A and 1B are schematic views from above and
below, respectively, of one embodiment of hand held data
entry unit 10 which is substantially pen-shaped and which
will hereinafter, for reasons of conciseness only, be referred
to as the "pen 10". The pen 10 is intended to be held for
essentially one handed operation between the thumb and
forefinger of either the left or right hand in the marmer of a
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 technicallimitations.Areading head 14, for
example a red or infra-red optical reading head (e.g., a 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 0 .degree. to 45 .degree. to the normal to the bar code
to be read.
On the upper surface of the pen shown in FIG. 1A 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 scanning 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 userofthe 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 Intel80486, etc.), although a special purpose or
specially configured unit (e.g. anASIC) 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
7 4. 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
unit 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 progrmed by means of control programs and data stored in the ROM 7 6 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 ofFIG. 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 units 10/40 connected via
respective telephone connections 50 (telephone lines, wireless telephone channels, 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 cardforusewith the pen 10. The card shows barcodes
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 marmer. 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

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 7 4 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 offby
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 con-

10

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

15

20

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 lefthanded operation has already selected and it is desired to use
the pen in a right-handed mode, then "Right-handed 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 manner
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

controlling the output of data via an optical link 153 to a
peripheral device (e.g., a printer) using for example, infra red
light;
controlling an interface to the display 20, the display interface functions being performed in the ASIC.
The optical link 153 could be implemented using the optical link technology described above for interfacing a hand
held unit with a base station. Indeed, the printer or other
peripheral device could be implement as, or connected to a
base station for the hand held unit.
FIG. 11 illustrates in more detail the configuration of the
ASIC 150.
The ASIC comprises the system controller 165 that controls the operation of the pen and of its associated components. In this embodiment system controller 165 consists of a
microcontroller core incorporated into the ASIC. In other
embodiments it could consist of some other control means
using, for example, one or more finite state machines.
If the system controller 165 is a microcontroller core, then
the data that controls its operation is stored in an internal
ROM 163 together with the external ROM 76. Alternatively,
there could be no internal ROM 163 and the system controller
165 will then obtain all the data from the external ROM 76.
Alternatively, again, the internal ROM 163 could be used
exclusively without an external ROM 78. However, this
would reduce the flexibility of the device. The use of the
internal ROM 163 is advantageous where a pre-defined
amount of the operations to be performed are fixed for all pen
types, whilst the remainder of the operation is dependent on a
particular model, to take account for example of language
variations, number of switches used to enter data, etc. The
RAM 161 in the ASIC can be used by the system controller
165 as a scratch pad RAM to speed up operations and in order
to reserve the maximum amount of RAM 78 for the storage of
the main data. This "main data" includes data identifying
information relating to selectable items of, for example, a
merchandising catalogue, which can be down loaded by telephonic transmissions from a remote station.
The microcontroller receives requests via the bus 84 which
is connected to the external bus 84 illustrated in FIG. 10.
However, in an alternative embodiment where the system
controller 165 consist of a number of finite state machines,
then control would be by means of the fixed interconnection
of the logic in the fixed state machines.
RAM 161 could be used as a short term data store leaving
the RAM 78 to store the main data, the data in RAM 78 being
retained by the battery 70. An additional battery (not shown)
could be provided for data retention to prevent the loss of data
from the RAM 78 or the RAM 161 in the event offailure of the
battery 70.
The switch interface 155 responds to the operation of the
switch 22 and ensures that the system controller 165 receives
signals which are devoid of bounce (resulting for example
from multiple operations of the switch due to the spring
operation within the switch).
The head interface 156 carries out the necessary signal
conditioning as required on receiving signals from the head
14. The signal conditioning will depend on the exact configuration of the head and preferably comprises simple buffering
of the data read. Alternatively, it could be implemented to
provide at least some of the bar code conversion operations as
will be apparent to one skilled in the art.
Selector 159 is controlled by the system controller 165 and
functions in such a manner to allow the microphone 152 and

the speaker 95 to provide standard audio telephony transmission or to allow the system controller to transfer the data over
the telephony network using, in the present embodiment,
conventional cellular telephone technology.
Thus the selector 159 enables the data entry device to be
used as a conventional cellular telephone for the transmission
of audio signals. In conventional telephony mode, the selector
159 takes signals from the microphone 152 that have been
processed by the signal processor 158 and directs the output
to the line interface 116. The processing performed by the
processor 158 can comprise, as will be apparent to one skilled
in the art, conventional operations of buffering the microphone to filter out any frequencies not required and to amplifY
the signal to a suitable level. Received audio data is directed
to the audio interface 157 which performs necessary signal
conditioning before passing the signal to the speaker 95.
In the data transfer mode, the selector takes the output from
the data formatter 160, which has prepared the data to be
transmitted over the cellular telephone network, and directs
this to the line interface 152. The speaker 95 is then used to
output any tones or audio messages indicating errors, correct
operation, etc., again via the audio interface 157.
Switching between modes can be accomplished using the
keys and/or the scanning sensor of the hand held unit in the
manner described above for the entry of data and/or commands.
The output formatter 164 prepares the data to be transmitted to a remote printer via an optical link 153 (not shown).
This transmission could be in any one of a number of forms,
for example, infra red light using technology as described
above for interfacing the pen with a base unit. Alternatively,
other remote link technology, for example a radio link, could
be provided.
FIG. 12 illustrates aspects from FIGS. 10 and 11 to illustrate in more detail the incorporation of an example of a
cellular telephone system within the data entry unit. The
telecommunications interface 116 comprises a line interface/
duplexer which is connected to an aerial178. The line interface/duplexer 116 is connected to a transmitter 170 and to a
receiver/synthesizer 172 implemented in the selector 159.
Also implemented in the selector 159 is selector logic 174 for
connecting the transmitter 170 and the receiver/synthesizer
172 to the signal processor 158, the audio interface 157, the
data formatter 160 and the control logic 165 within the ASIC
150.
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 FIGS. 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 sonnd 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.
Although in the example of a card or other carrier shown in
FIG. 6 a set ofbar codes for only numeric and command 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 ofFIGS. 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
telecommnnications interface for the telephonic transmission
of information is only provided in a hand held nnit 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 nnit also
having a telecommnnications interface, either of the same or
a different type.
