EXHIBIT 3.23

WO01/027868

PCT/US00/27720

such applications, a simple graphic underlay such as a plastic button

template could be slid into a slot underneath the transparent sensor.
Advertising logos or other graphics not related to the device user
interface could also be placed under the sensor.
5

f) Display-enhanced capacitive sensor for a personal computer. To

enhance the user interface for personal computers, the transparent twodimensional sensor can be used in conjunction with an underlying LCD

display device for a display-enhanced sensor input device. The underlying
LCD screen can provide information such as a record of the current stroke

10

or gesture for handwriting recognition, signature/text capture or graphics
software. Soft buttons, icons, scroll bars, or other zones of enhanced

sensor functionality could also brought to attention on the LCD screen.
In more general terms, a display-enhanced sensor could contain specific
applications that interface with the host computer. Examples include, but
15

are not limited to, mimicking a numeric keypad, launching applications, or
providing menus or soft buttons that are specific to a software
application that is running concurrently on the host computer. Finally,
advertising logos, or bitmapped images and photographs can be drawn in
the LCD screen to enhance functionality or as additional display space.

20

g) Display-enhanced capacitive sensor for personal computer that

detaches to function as a stand alone handheld device. A further
extension of the display-enhanced sensor is a detachable transparent

sensor and LCD display assembly. While the sensor and LCD is attached
to the host computer, it functions as a display-enhanced sensor as

25

described in the previous section. However, the sensor and LCD
assembly also contains hardware and software to function as a stand

alone, handheld device, for example, a personal digital assistant (PDA)
device such as a 3Com PalmPilot" or a Rolodex Rex". The detachable

sensor has distinct benefits. First, it serves as a simple security
30

mechanism for the host computer since most modern computer operating

PCT/US00/27720

systems are almost impossible to use without a pointing device. Second,
the detachable capacitive sensor provides an obvious location to store the
PDA without need for a separate cradle or docking station. Because the

input is a capacitive position sensor, the finger pointing performance of
5

such a device is the same as the current state-of-the-art computer
touchpads and vastly superior to the resistive pads that are currently in
use on most PDA devices.

h) Transparent capacitive sensor as an aesthetic improvement to
personal computer design. In some modern computers, transparency is

10

used for purely aesthetic or artistic purposes. A transparent sensor array
allows industrial designers to incorporate a pointing device onto a

computer but allow the surface underneath to be viewable. This might
allow the underlying electronics of thë computer, or other artwork such
as, but no limited to, logos, advertising, or labels, to be viewable.
15

Described herein is a preferred embodiment, however, one skilled in
the art that pertains to the present invention will understand that there

are equivalent alternative embodiments.

Specification

1. Title of Invention
Position input device

APLNDC00026960

2. Claim
In a device that generates coordinate values of points indicated on a tablet, a position input device
characterized by being equipped with a means that detects when two or more points are indicated
simultaneously.
3. Detailed Description of Invention
Field of Invention
This invention pertains to position input devices, such as highly practical tablet devices.
Technological Background of Invention and its Problems
Numerous position input devices have been developed as devices to input text and graphic
information. These position input devices take input by detecting position coordinates on a tablet as
indicated by a pen or the like, and they use a variety of systems. Many conventional systems, for
example, have used electromagnetic induction/magnetostrictive wire systems or the like, so they
used special pens and required cords. While that meant some mconvemence, embedding switches
and the like in the pen allowed some types of functions to be easily implemented.
Several systems that can input without using a special pen have also been devised. With these
systems, anything can serve as the pen, or the hand can be used for input directly, greatly improving
on the inconvenience of conventional systems. Since they don't use special pens, however, features
cannot be added to pens, requiring separate switches to be provided for function input or specific
areas of the tablet to be defined as functions.
Figure 1 shows one such example. Part (a) of Figure 1 shows functions defined on the face of the
tablet; part (b) shows separate function switches. These make the device much more troublesome to
use, since a separate switch must be pressed or different points pressed twice to input a function,
and cost tends to rise when separate switches are added. It also forces the device to become larger
or to reduce the actual space available for coordinate input.
Purpose of the Invention
The purpose of this invention is to provide a position input device of simple constitution that can
easily provide functions and the like.

Summary of the Invention
This invention is characterized by being equipped with a circuit that detects when a plurality of
points are indicated simultaneously in a tablet device for inputting coordinates. In other words,
when two points are indicated simultaneously by a pen, finger or the like, they are input to a
computer or the like as, for example, a function, using the signals from such detection.

APLNDC00026961

Effect of the Invention
Using this invention allows the creation of an inexpensive tablet that does not use a special pen,
does not require installation of switches or the like for indicating special functions, and that allows
simple creation of text, graphics and the like because functions can be entered in a simple manner.
Also, the signal that indicates detection that two points have been indicated simultaneously can also
be used in various ways other than for functions.
Embodiment of the Invention
The invention will be described below with reference to an embodiment. Figure 2 shows one
example of a tablet plate that uses this embodiment, which might have a constitution that disposes
conducting wires on a pressure-sensitive conductive rubber sheet. A plurality of conductive wires
11 are arrayed in parallel at a specific pitch, each of the conductive wires 11 has electrode parts 12
and 13 connected to drive circuits 14a and 14b and detection circuits 15a and 15b, and adjacent
conductive wires 11 are constituted to be in combinations such that they do not connect to the same
drive circuit and same detection circuit. In other words, 37 conductive wires 11 are shown arrayed
in parallel in Figure 2, with odd-numbered conductive wires 11 connected to drive circuit 14a and
detection circuit 15a through electrode part 12 and even-numbered conductive wires 11 connected
to drive circuit 14b and detection circuit 15b through electrode part 13. These drive circuits 14a and
14b are constituted by switch circuits 16a and 16b that supply power supply voltage +V to
conductive wires 11. Conductive wires 11 connected to electrode part 12 are formed in a plurality
of groups connected in common once for every prescribed number of wires. In the example shown

in Figure 2, the conductive wires 11 at places 12x+1, 12x+3, 12x+5 ... 12x+11 (x=0, 1, 2) are
respectively connected in six groups. Also, at electrode part 13, adjacent conductive wires 11 form a
plurality of groups connected at every interval of a specific number of wires so that all the groups
connected respectively to electrode part 12 and electrode part 13 are different from their adjacent
conductive wires 11. In other words, in the example shown in Figure 2, conductive wires at places

4x+12y+2 and 4x+12y+4 (x, y-0, 1, 2) are respectively connected six groups. Switches 16a and 16b
are connected separately to the drive circuits connected to these 12 groups and voltage V supplied
by turning these switches on.
A tablet plate of this sort is arranged as shown in Figure 3. In other words, a pressure-sensitive
conductive rubber sheet 23 is placed between two tablet plates 21 and 22 with the conductive wire
of the respective plates running perpendicular to each other. When pressure is placed locally by a
position-indication operation using a pen, finger or the like, resistance decreases in pressuresensitive rubber sheet 23 and two conductive wires running perpendicularly in top and bottom tablet
plates 21 and 22 short-circuit selectively and locally. Further, in this embodiment, the pitch of the
conductive wires is set such that two adjacent wires in each of the top and bottom conductive wires
short-circuit when a pen or finger applies pressure to any one spot on the tablet.
Figure 4 is a block diagram of this embodiment, which uses the aforementioned tablet. Drive
circuits 32 and 33 and detection circuits 34 and 35 are connected respectively to the two electrode

APLNDC00026962

parts of tablet 31. These two detection circuits 34 and 35 respectively detect when odd-numbered
and even-numbered conductive wires are conducting. Figure 5 is a bit configuration diagram that
shows the status of conductive points where an indicated position is detected in this detection circuit.
Next, based on the signal of the detection line detected by detection circuit A 34 and the detection
line detected by detection circuit B 35, tablet controller 36 sends the coordinate values of the
indicated point or a function to the central processing unit (CPU) 37, CPU 37 creates output
information using information from tablet controller 36, this output information is sent to display 38,
and text, graphics or the like are displayed, following the flow chart shown in Figure 6. Also, only
one tablet is shown in Figure 4, but two tablets, top and bottom, are connected to tablet controller

36.
Next we will explain the operation of this embodiment with reference to the flowchart shown in
Figure 6. First, the bottom tablet plate 22 is set to the drive side by turning all its drive circuit
switches to ON, then the top tablet plate 21 is set to the detect side by turning all its drive circuit

switches to OFF. When a position indication operation is then performed, the conductive rubber
sheet 23 becomes conductive at the indicated position and the voltage (sm st) supplied from
aforementioned drive circuit electrode parts 22a and 22b is applied to conductive wires 11 of top
tablet plate 21 via conductive rubber sheet 23. Tablet controller 36 searches with detection circuit
34 on the electrode part 21a side of the top tablet 21 for the conductive wire 11 at which the
aforementioned voltage appears. If at this time two points are pressed simultaneously, two
conductive points become ON, as shown in Figure 5, and can easily be detected. The fact that two
points have been pressed simultaneously is sent to the CPU as a function. When only one location is
ON, the same kind of operation is performed by detection circuit B 35 at electrode part 21b. Thus,
when only one point is pressed, the specified position coordinate Y of one direction is found from
the group of detection lines detected by detection circuit A 34 and 35. Thereafter, all the switches of
the drive circuits of bottom tablet 22 are turned OFF to set it to the detection side, all switches of
the drive circuits of top tablet 21 are turned ON to set it to the drive side, and coordinate X is found
by executing the same flow as above. The coordinate values found are sent to the CPU. In this flow,
a function is sent when two or more points are pressed simultaneously, but it can be allocated to
several functions by the distance between, direction of, etc., the two pressed points. Also, any tablet
that can detect when two points are pressed simultaneously can be used for this, not only the tablet
described above, and it is also possible to implement more functions with three or more points
rather than two points. Further, the control flow shown in Figure 6 might be executed by, for
example, microprocessor control, but the detection control algorithm can naturally be changed in
various ways.
Next, we show an example of an operating procedure for this embodiment with reference to Figure
7. A co----------d menu 12 is defined in one part of the display screen 41 shown in Figure 7a, and the
user moves the cursor 43 as desired on the tablet with a finger, for example, to the CIRCLE
command, and when a different finger then simultaneously specifies another appropriate point, the
tablet sends the CPU a signal that two points have been specified. Figure 7b shows how this looks,
with the thumb and pointer finger being used on the tablet 44. The CPU knows from the cursor

APLNDC00026963

location and from the signal that two points are specified that the CIRCLE co-···· ---d was specified,
and it waits for the center position and a position on the circumference to be input. Next, the user
moves the cursor with a finger to the position desired for the center of the circle, and when two
points are specified simultaneously using another finger as above, now the CPU interprets the
cursor position as the center position of a circle. By similarly specifying a point on the
circumference, the CPU draws a circle as specified as shown in Figure 7c.
By using this embodiment, simple cursor movements and making the cursor position the target of
an operation can both be accomplished with extremely simple operations.
Further, using this invention provides the advantage of being able to enter functions without using
special pens or function switches, but functions need not be used, allowing use as signals other than
position specification input by indicating two or more points simultaneously.

[Detailed Description of the Invention]
[0001]
[Technical Field of the Invention] The present invention relates to a user input
device for inputting object operations, commands and the like to a computer; and in particular
relates to a user input device with which object operations, commands and the like are directly
input to a computer using a user's fingertip.
[0002] More specifically, this relates to a user input device that inputs object
operations, commands and the like to a computer in a noncontact manner; and in particular
relates to a noncontact user input device that can recognize two or more points of information,
the shape of a proximate object, and information on the distance to an object.
[0003]
[Prior Art] In the wake of recent technological innovations, general-purpose type
computer systems have been developed and marketed, which are referred to as workstations
(WS) or personal computers (PC), and have better added value and improved functionality with
relatively small sizes, at low cost; these have become highly prevalent in universities and other
research organizations, in businesses and other offices, as well as in the day-to-day life of
ordinary households.
[0004] A computer system generally provides an "interactive," which is to say
dialogical, processing environment, by way of operating in response to user input commands
and displaying the processing results on a display screen. Recent trends include the movement
from old character-based user input environments, which is to say, "CUls (Character User
Interfaces)" which use a conventional keyboard, the DOS (Disk Operating System) shell screen

APLNDC00026977

JP-2002-342033-A

being representative of these, to "GUls (Graphical User Interfaces)" whereby graphics-based
user input has been implemented. In GUI environments, the computer system provides a
simulated desktop and a large number of icons on a display screen.
[0005] All of the resource objects that are handled in the computer system, such as
files, are represented as icons on the desktop that is provided by the GUI. The user can
perform computer operations intuitively by performing operations (for example, clicking or
dragging and dropping) directly on objects that are displayed on the screen, by using a mouse
or the like on icons that symbolize programs, data, folders, devices and the like, on the display
screen. Furthermore, buttons [sic] are provided on the desktop for instantly calling up various
different functions, which is to say, computer processes, such as menu bars and toolboxes, and
thus command input methods are becoming increasingly intuitive and easy to understand.
[0006] With the introduction of the GUI environment, a computer can be properly
operated without the user having to undergo special training in specific command names,
command operation methods or the like, and without performing complex key input.
[0007] In such GUI environments, coordinate specification devices such as, for
example, mice, TrackPoints, joysticks, tablets and touchpads are representative of user input
devices that can be used. From among these, the mouse is deeply established in the computer
industry, and almost all users have become comfortable with operations based on dragging and
dropping. It is not unreasonable to say that there is absolutely no need for special training in
mouse operation when computers are newly introduced to various aspects of everyday life,
such as in offices and households. GUls based on mouse operations are already established
[as the norm] for most users, and provide multiple general usage functions.
[0008] In the GUI environment, the user can perform input operations in a manner
that is easy to understand, by way of interaction with the computer, while being guided by the
content of the display on the computer screen. User input devices using touch panels can be
cited as one example of a further advancement in such interactive input. In this case, a touch
panel that reads coordinate values specified by a pen or the user's fingertip is overlaid with a
screen and therefore, as differs from the case of mouse operations, there is no need for the
user remove their line of sight from the screen, and it is possible to directly indicate a desired
display object with one's own fingertip, whereby operability is further improved.
[0009] However, for user input based on conventional touch panels, it is necessary to
actually touch the surface of the touch panel with the fingertip.
[0010] Furthermore, if there are two or more contact points on the panel, it is not
possible to measure each position independently. For example, if we consider a usage situation

in which a meeting is conducted, in which several people are positioned so as to surround a
touch panel, it is possible that the fingertips of several participants touch the touch panel at the
same time, but the system cannot recognize such phenomena. This would result in the first
touch being given precedence, or in the multiple touches interfering/being mixed up.
[0011] Furthermore, user input with the conventional touch panel system is based on
point data input, and it is not possible to recognize the shape of proximate objects or
information on distance to a proximate fingertip.
[0012]
[Problems to Be Solved by the Invention] An object of the present invention is to
provide an excellent user input device, with which object operations, commands and the like
can be input directly to a computer using a user's fingertip.
[0013] A further object of the present invention is to provide an excellent user input
device, with which input to a computer such as object operations and commands can be
performed in a noncontact manner.
[0014] A further object of the present invention is to provide an excellent noncontact
type user input device, with which it is possible to recognize two or more points of information,
the shape of proximate objects, information on the distance to an object and the like.
[0015]
[Means for Solving the Problems and Operation] The present invention, which
was made in light of the problems described above, is a noncontact type user input device for
performing input in a noncontact manner using a user's fingertip or the like, the noncontact type
user input device being characterized by comprising a plurality of linear transmission electrodes,
a transmitter that supplies AC current for transmission to the transmission electrodes, a plurality
of linear reception electrodes disposed so as not to touch the transmission electrodes, and a
receiver that receives AC current flowing in the reception electrodes, a circuit equivalent to a
capacitor being formed at each of the points of intersection between the transmission
electrodes and the reception electrodes.
[0016] With a noncontact type user input device of this sort, a first capacitor
equivalent circuit, which is equivalent to a capacitor, is virtually formed at each point of
intersection between a transmission electrode and a reception electrode.
[0017] Furthermore, a second capacitor equivalent circuit is virtually formed, in
parallel with the first capacitor equivalent circuit, in response to an electroconductive object
such as a user's fingertip having approached.

1-800-844-0494 [e-mail]

APLNDC00026979

JP-2002-342033-A

Page 6

[0018] The capacitance of the second capacitor equivalent circuit changes in
accordance with the degree of proximity of the electroconductive object such as a fingertip.
Accordingly, the AC current passing through the first capacitor equivalent circuit, which is
connected in parallel with the second capacitor equivalent circuit, likewise changes in
accordance with the degree of proximity of the electroconductive object such as a fingertip.
Utilizing such a phenomenon, the noncontact type user input device can measure, not only the
fact that the fingertip has approached, but also the distance to the fingertip when this has
approached.
[0019] Furthermore, the transmitter may scan the transmission electrodes with the
AC current, and a signal processing unit may be further provided, which detects the input
position by way of the positional relationship between the transmission electrode that
transmitted the AC current and the-reception electrode that received the AC current.
[0020] In such a case, the noncontact user input device can measure the contour of
the proximate object by tracking the points of intersection between the transmission electrodes
and the reception electrodes at which input positions have been detected. In other words, the
noncontact user input device can recognize not just simply the fact that an object such as a
user's fingertip has approached, but also the shape of the object. Furthermore, even if two or
more users try to access the noncontact user input device at the same time, it is possible to
recognize the fingertips of each person separately.
[0021] The transmitter may apply AC current to the transmission electrodes while
scanning. Then, the noncontact user input device may be further provided with a signal
processing unit, which detects the input position by way of the positional relationship between
the transmission electrode that transmitted the AC current and the reception electrode that
received the AC current.
[0022] The signal processing unit utilizes the difference between the capacitance of
the first virtual capacitor that is formed at the point of intersection between the transmission
electrode and the reception electrode and the capacitance of the second virtual capacitor that is
formed in response to an electroconductive object such as a user's fingertip having approached
[the] point of intersection between [the] transmission electrode and [the] reception electrode, so
as to detect the electroconductive object having approached.
[0023] Furthermore, the signal processing unit detects the position of an
electroconductive object by integrating the capacitances of the capacitors that are virtually
formed between the electroconductive object such as the user's finger and the electrodes.

[0024] A display-integrated user input device can be constituted by overlaying a user
input area comprising at least the intersection of the plurality of transmission electrodes and the
plurality of reception electrodes of the noncontact type user input device of the present
invention on a display screen of a display device. For example, the noncontact type user input
device of the present invention may be constituted so as to be united with a liquid crystal
display or an organic LED.
[0025] For example, the noncontact type user input device of the present invention
may be constituted so as to be united with a display device constituted by stacking an anode
electrode layer and a cathode electrode layer, with an insulating layer therebetween.
[0026] In such a case, the user input area can be constituted by the intersection of
the plurality of transmission electrodes and the plurality of reception electrodes, by way of
combining one electrode layer and another electrode layer. That is to say, an AC current for
detection may be applied to one electrode layer, to which a DC voltage is applied, and the AC
current received by way of the other electrode layer may be detected.
[0027] Further objects, features and advantages of the present invention will be
apparent from the following embodiments of the present invention and the detailed description
based on the accompanying drawings.
[0028]
[Modes of Embodiment of the Invention] Hereafter, embodiments of the present

invention are described in detail with reference to the drawings.
[0029] FIG. 1 schematically illustrates the basic configuration of a noncontact type
user input device 1 according to one mode of embodiment of the present invention.
[0030] As shown in the drawing, a noncontact type user input device 1 comprises: a
plurality of linear transmission electrodes 11-1, 11-2, ..., 11-m; a transmitter 12 that supplies an
AC current for transmission at a predetermined frequency (for example, 100 kHz) to the
transmission electrodes 11-1...; a plurality of linear reception electrodes 15-1, 15-2, ..., 15-n,
which receive the AC current from the transmission electrodes 11-1..., by way of an
electrostatic effect; and a receiver 16 that receives the AC current flowing in the reception
electrodes 15-1... . The receiver 16 comprises: an AM modulator comprising a band pass filter
(BPF) 16A, which allows only AC current at a predetermined frequency range to pass, an
amplifier 16B and a detector 16C; and an A/D converter 16 D, that converts the detector output
to a digital format signal.
[0031] It will be understood from FIG. 1 that the reception electrodes 15-1, 15-2, ...,
15-n have points of intersection with the reception electrodes 11-1, 11-2, ..., 11-m, but these

electrodes do not contact each other at these points of intersection. In other words, a circuit
equivalent to a capacitor that stores electrical charge is substantially formed at each
intersection between the electrodes. Accordingly, when the AC current passes through a
transmission electrode, an AC current flows in the reception electrodes facing this as a result of
electrostatic induction via this point of intersection. The area in which these transmission
electrodes 11-1, 11-2, ..., 11-m and the reception electrodes 15-1, 15-2, ..., 15-n cross each
other constitutes a user input area for the noncontact type user input device 1. As shown in the
drawing, this user input area extends in two dimensions.
[0032] The transmitter 12 applies the AC current to the transmission electrodes
11-1, ... while scanning. Accordingly, for a certain brief period of time, an AC current flows in the
reception electrodes 15-1... from the capacitor equivalent circuit at the point of intersection with
the corresponding transmission electrode, and the input position can be detected from the
positional relationship between the transmission electrode that has transmitted the AC current
and the reception electrode that has received the AC current. For example, by performing
predetermined computational processing of the A/D converted output signals from the reception
electrodes 15-1... with a processor 20, two-dimensional user input can be detected via the user
input area.
[0033] In the illustrated example, the transmission electrodes 11-1, 11-2, ..., 11-m are
arrayed substantially parallel, while the reception electrodes 15-1, 15-2, ..., 15-n are arrayed in
a direction orthogonal to the transmission electrodes 11-1..., and the user input area is a
substantially planar area in which the electrodes are combined with each other, in a uniform
manner, at the nodes of a lattice. However, the gist of the present invention is not particularly
limited to such a mode, and so long as the transmission electrodes and the reception
electrodes cross each other without contact, this may be a non-planar shape, such as a sphere
or another curved surface shape.
[0034] A certain intersection between a transmission electrode 11 and a reception
electrodes 15 is shown enlarged in FIG. 2. Furthermore, an equivalent circuit at the point of
intersection between this transmission electrode 11 and this reception electrode 15 is shown in
FIG. 3.

[0035] At the point of intersection where the transmission electrode 11 and the
reception electrode 15 cross over, a circuit equivalent to a capacitor is formed, as shown in FIG.
3.

[0036] Here, if AC voltage is applied to the transmission electrode 11 side, capacitive
coupling occurs, by way of a capacitance Ca between the transmission electrode 11 and the

reception electrode 15, and an AC current is generated in the reception electrode 15. The
strength of the current that passes through this capacitor Ca is picked up as digital data by way
of performing signal processing with parts [that include] the band pass filter 16A, which is tuned
to the transmission frequency of the AC voltage at the transmitter 12, the amplifier 16B, the
detector 16C and the A/D converter 16D. The strength of the AC current received by the
reception electrode 11 is dependent only on the capacitance Ca of the capacitor.
[0037] The capacitance Ca is maintained at a static fixed value so long as the
transmission electrode 11 and the reception electrode 15 are not deformed or the like.
Accordingly, so long as the same AC voltage is applied on the transmission electrode 11 side,
the strength of the AC current that is received on the reception electrode 15 side will be
constant.
[0038] Next, the mechanism whereby an object such as a user's fingertip is detected
in a noncontact manner by the combination of such a transmission electrode 11 and reception
electrode 15 is described.
[0039] FIG. 4 shows the situation in which a user's fingertip is proximate to a certain
point of intersection between a transmission electrode 11 and a reception electrode 15.
Furthermore, FIG. 5 shows the equivalent circuit at the point of intersection between the
transmission electrode 11 and the reception electrode 15, when the user's fingertip is proximate
to a certain point of intersection between the transmission electrode 11 and the reception
electrode 15.
[0040] As described above, a circuit is formed which is equivalent to a capacitor Ca at
the point of intersection at which the transmission electrode 11 and the reception electrode 15
cross over.
[0041] Furthermore, a human body [part], such as a fingertip, can be considered a
virtual ground point (earth). Accordingly, the equivalent circuit is configured so that the capacitor
Ca, which is formed between the transmission electrode 11 and the reception electrode 15, and
virtual capacitors Cb1 and Cb2, Which are formed in series between the human body [part] and
the transmission electrode 11 and the human body [part] and the reception electrode 15, are
connected in parallel.
[0042] Accordingly, if an AC voltage is applied to the transmission electrode 11 side,
the strength of the AC current that is generated by capacitive coupling by way of the
capacitance Ca between the transmission electrode 11 and the reception electrode 15, which is
to say, the current that is detected on the reception electrode 15 side, is weakened by an
amount corresponding to the current that flows to ground via the capacitor Cb1·

Page 10

[0043] The capacitance Ca is maintained at a static fixed value so long as the
transmission electrode 11 and the reception electrode 15 are not deformed or the like.
Conversely, the capacitances Cbi and Cb2 Of the virtual capacitors that are formed between the
human body [part] and the transmission electrode 11 and between the human body [part] and
the reception electrode 15, which are formed in senes, increase in accordance with the
approach of the human body [part] to the transmission electrode 11 and the reception electrode
15.
[0044] Consequently, if the same AC voltage is applied to the transmission electrode
11, the strength of the AC current that is detected in the reception electrode 15 decreases in
accordance with the approach of the human body [part] to the transmission electrode 11 and
the reception electrode 15.
[0045] Utilizing such a phenomenon, the processor 20 can use the reception signal
that has been AM modulated by the AM modulator 16 and then converted to digital format by
the A/D converter 16D to determine whether or not a human body [part] is close to the point of
intersection between the electrodes, or to measure the degree of proximity (distance) of the
human body [part].
[0046] As shown in FIG. 1, in the noncontact user input device according to this
mode of embodiment, the points of intersection between such transmission electrodes 11-1...
and reception electrodes 15-1... are arrayed in an mxn matrix. For example, the intersections
between these electrodes can be disposed on an input panel having a predetermined flat
surface (or curved surface).
[0047] The AC voltage is applied to each of the transmission electrodes 11-1,
11-2, ..., 11-m in time division. Then, the AC currents generated in each of the reception
electrodes 15-1, 15-2, ..., 15-n, which correspond to each of these, are sequentially measured,
whereby it is possible to determine which point of intersection in the user input area the human
body [part] is close to.
[0048] In the noncontact user input device 11 according to this mode of embodiment,
an electrostatic effect is utilized, and therefore it is not necessary for the human body [part] to
make direct contact with the electrode in order for the human body [part] such as the user's
fingertip to be detected. Furthermore, by integrating the detection values obtained at proximate
points of intersection, it is possible to measure the distance from the input surface to the
fingertip by way of performing common geometrical calculations or the like.
[0049] Furthermore, by virtue of the constitution shown in FIG. 1, it is possible to
independently drive each point of intersection between the electrodes. In other words, because

it is possible to pick up detection values independently from each point of intersection, if a
plurality of objects (for example, the right-hand and left-hand of the same user, or the hands of
a plurality of users) approach the user input area at the same time, if the distance is greater
than the pitch distance between the points of intersection, these can be recognized as
independent objects. In other words, it is possible to measure the locations of a plurality of
objects at the same time.
[0050] Furthermore, by tracking the points of intersection at which object proximity
has been simultaneously detected, it is possible to capture the shape or contour of the
proximate object.
[0051] FIG. 6 depicts a variant of the noncontact user input device 1.
[0052] When the user's fingertip has approached an area surrounded by the grid
points A, B, C, D, virtual capacitors CI, Ca, Cs, Co are formed between the transmission
electrodes 11-i, 11-j as well as the reception electrodes 15-p, 15-q and the user's fingertip.
[0053] The capacitances of these virtual capacitors Ci, Ca, CP, Co vary with the
distance between the electrodes and the user's fingertip.
[0054] Accordingly, by integrating the values from a plurality of points of intersection
of the human body [part] and the electrodes, it is possible to measure the position of a hand,
which is intermediate between the points of intersection. That is to say, the position
measurement system [sic] of the noncontact user input device 1 according to this mode of
embodiment can be made finer than the gap between the points of intersection of the
electrodes.
[0055] FIG. 7 depicts another variant of the noncontact user input device 1.
[0056] As has already been described with reference to FIG. 1, the noncontact user
input device 1 according to this mode of embodiment is such that the points of intersection
between the transmission electrodes 11-1... and the reception electrodes 15-1... are arrayed in
an mxn matrix in the user input area. Furthermore, by virtue of a constitution such as shown in
FIG. 1, it is possible to independently pick up detection values from points of intersection by
independently driving the points of intersection between the electrodes.
[0057] Accordingly, as shown in FIG. 7, if a plurality of user fingertips are present in
the user input area, these can be independently recognized at the points of intersection where
the user fingertips are proximate. Consequently, it is possible to receive simultaneous input
from a plurality of users using one single user input device.
[0058] Furthermore, FIG. 8 depicts another variant of the noncontact user input
device 1.

[0059] As has already been described with reference to FIG. 1, the noncontact user
input device 1 according to this mode of embodiment is such that the points of intersection
between the transmission electrodes 11-1... and the reception electrodes 15-1... are arrayed in
an mxn matrix in the user input area. However, in the example shown in FIG. 8, the gaps
between the transmission electrodes 11-1, 11-2,..., 11-m and the reception electrodes 15-1,
15-2,..., 15-n are provided so as to be sufficiently narrow, and the scan speed with which the
transmitter 12 applies the AC voltage to the transmission electrodes 11-1 is made sufficiently
fast.
[0060] In such a case, as shown in FIG. 8, if the user brings their palm close to the
user input area, by tracking the points of intersection at which the approach has been detected,
the shape of the object, which is to say, the palm, can be recognized.
[0061] In other words, by making the pitch distance between the electrodes
sufficiently small and making the scan speed for the transmission electrodes sufficiently fast,
the noncontact user input device 1 according to this mode of embodiment can recognize the
shape of objects.
[0062] Applications in which the noncontact user input device 1 according to this
mode of embodiment is combined with other devices can be conceived. For example, by
overlaying the noncontact user input device 1 on a flat display such as a liquid crystal display
(LCD) or an organic EL [sic], it is possible to constitute a user input device having an integrated
display. With such a user input device, the user can easily and intuitively perform command
input to the computer while being guided by the content of GUI screens that are output on the
display. The user can perform input operations without removing their line of sight from the
display screen, and therefore the risk of erroneous input is reduced.
[0063] FIG. 9 schematically depicts the cross-sectional structure of a noncontact user
input device 1 that is constituted so as to be united with a display device comprising an
electroconductive polymer-based light emitting element, which is to say, an organic LED.
[0064] As shown in this figure, an anode electrode layer and a cathode electrode
layer comprising an electroconductive polymer are stacked, with an insulating layer comprising
an organic material therebetween. Furthermore, the anode electrodes and the cathode
electrodes are disposed running straight with respect to each other'. This is similar to the
structure shown in FIG. 1 in which the transmission electrodes 11-1... and the reception
electrodes 15-1... are disposed intersecting so as not to touch each other.
1 It is likely that there was a typographical error in the original Japanese at this point, as a homophone would read "orthogonal
to each other." -- trans.

[0065] In the organic display, in order to cause the pixels to emit light, DC voltage is
successively applied to the electrodes in one of the electrode layers, in the screen scan
direction.
[0066] In this mode of embodiment, an AC voltage for detecting a human body [part]
is applied superimposed on the DC voltage that flows in one of the electrode layers.
Consequently, an AC current is received in the other electrode layer. At the point of intersection
that is approached by a human body [part] such as a user's fingertip, the strength of the
received AC current decreases, and it is therefore possible to specify the position occupied by
the user's finger and to recognize the shape of the proximate object.
[0067] With a constitution such as shown in FIG. 9, without changing the constitution
of the screen in the organic display, the display device can be used as-is, as a noncontact type
user input device.
[0068] Furthermore, an organic display is generally flexible and can be bent at will.
Accordingly, with application examples such as shown in FIG. 9, it is possible to constitute a
spherical or cylindrical user input integrated display device.
[0069] [Supplement] Hereabove, the present invention has been discussed with
reference to specific embodiments. However, it is self-evident that those skilled in the art can
modify and make substitutions in the embodiments, within a scope that does not depart from
the gist of the present invention. In other words, the present invention has been disclosed in the
modes that have been illustrated by way of example, but these are not intended to be limiting
interpretations. The scope of the present invention should be judged by referring to the claims
recited at the outset.
[0070]
[Effects of the Invention] As described in detail above, by virtue of the present
invention, it is possible to provide an excellent user input device, with which object operations
and commands and the like can be directly input to a computer using a user's fingertip.
[0071] Furthermore, by virtue of the present invention, an excellent user input device
can be provided with which input to a computer, such as object operations and commands, can
be performed in a noncontact manner.
[0072] Furthermore, by virtue of the present invention, an excellent noncontact type
user input device can be provided, with which it is possible to recognize two or more points of
information, the shape.of a proximate object, information on distance to the object and the like.
[0073] In the noncontact type user input device according to the present invention, a
first capacitor equivalent circuit, which is equivalent to a capacitor, is virtually formed at each of

the points of intersection between the transmission electrodes and the reception electrodes.
Furthermore, in response to the approach of an electroconductive object, such as a user's
fingertip, a second capacitor equivalent circuit is virtually formed in parallel with the first
capacitor equivalent circuit. The capacitance of this second capacitor equivalent circuit changes
in response to the degree of proximity of the electroconductive object, such as a fingertip, and
consequently the AC current passing through the first capacitor equivalent circuit changes.
Accordingly, utilizing such a phenomenon, it is possible to not only [detect] contact with the
fingertip but also measure the distance to the fingertip when this has approached.
[0074] Furthermore, by way of scanning the input of an AC current to the
transmission electrodes, it is possible to detect the input position on the basis of the positional
relationship between the transmission electrode that transmitted the AC current and the
reception electrode that received the AC current. By tracking the points of intersection between
the transmission electrodes and the reception electrodes at which input positions have been
detected, it is possible to measure the contour of a proximate object. In other words, the
noncontact user input device can not just simply detect when an object such as a user's
fingertip has approached, but also recognize the shape of the object. Furthermore, even if two
or more users try to access the noncontact user input device at the same time, it is possible to
recognize the fingertips of each person separately.

(54) NON-CONTACT TYPE USER INPUT DEVICE
(57)Abstract:
PROBLEM TO BE SOLVED: To recognize the information of
two or more points and the shape of an approaching object.
SOLUTION: A non-contact type user input device is
provided with a plurality of linear transmission electrodes, a
transmitter supplying an AC current for transmission to the
respective transmission electrodes, a plurality of linear
reception electrodes arranged so as not to be in contact
with the respective transmission electrodes and a receiver
receiving the AC current flowing through the reception
electrodes. A capacitor is formed at each intersection of
the transmission electrode and the reception electrode, a
parallel capacitor is formed corresponding to the approach
of the fingertip of a user and the capacitance of the
capacitor changes corresponding to the approaching degree
of the fingertip. Recognition is performed by utilizing the
change of the AC current passing through the capacitor
between the electrodes.

Docket No. 106842009000
Client Reference No. P3266US1

The information contained in this Supplemental Information Disclosure Statement under
37 C.F.R. § 1.97 and § 1.98 is not to be construed as a representation that: (i) a complete search has
been made; (ii) additional information material to the examination of this application does not exist;
(iii) the information, protocols, results and the like reported by third parties are accurate or enabling;
or (iv) the above information constitutes prior art to the subject invention.
A filing fee was submitted with the December 19, 2008, electronic filing of the
Information Disclosure Statement, so Applicants do not believe an additional fee is required.
However, in the unlikely event that the transmittal form is separated from this document and the
Patent and Trademark Office determines that an extension and/or other relief (such as payment of a
fee under 37 C.F.R. § 1.17 (p)) is required, Applicants petition for any required relief including
extensions of time and authorize the Commissioner to charge the cost of such petition and/or other
fees due in connection with the filing of this document to Denosit Account No. 03-1952
referencing 106842009000.
