International Publication 2008 / 093683A1

  The input device described in Patent Document 1 has a structure in which a pair of drive electrodes and a pair of detection electrodes are arranged with an interval in the X direction and the Y direction. It is possible to form a rough detection region over the entire area and detect the moving direction when the hand is moved greatly. However, since this input device cannot detect the movement of a finger or hand on the XY coordinates, it is not possible to input such that the display content on the screen is moved finely on the XY coordinates.

  Also, in recent personal computers, a capacitive detection panel is superimposed on the front of the display screen, and the display content is displayed by touching the display screen while viewing the display content through the detection panel. Something that changes. However, since this personal computer requires an operation in which the hand is released from the keyboard while the keyboard is being operated, and the hand is extended to the display screen to touch the screen, the input operation may be inconvenient.

  The present invention solves the above-described conventional problems, and provides an input processing device capable of performing a two-dimensional input operation by operating a front or left / right side of a key arrangement region of a keyboard device with a finger. The purpose is to do.

  Another object of the present invention is to provide an input processing device that can perform operations equivalent to operating the detection panel on the keyboard device when the detection panel is superimposed on the display screen. .

The present invention relates to a keyboard device having a key arrangement area in which a plurality of input keys are arranged, a display device having a display screen and a screen detection panel overlapping the display screen, and a display device according to input operation of the keyboard device. In an input processing device having a control processing unit for controlling display contents,
The keyboard device includes a first detection unit located in front of the key arrangement region and a second detection unit located at least one of the left and right sides of the key arrangement region. Both the detection unit and the second detection unit have elongated detection regions, and the long sides of the detection regions are arranged so that the long sides of the detection regions are along the arrangement direction of the input keys . It is arranged along the edge,
The first detection unit and the second detection unit are electrostatic sensors that can detect at least a two-dimensional operation in the detection region, and the control processing unit includes the first detection unit and the second detection unit. in response to the operation signal obtained from the detection unit is changed to the display content,
The control processing unit further changes the display content in the same manner when operating the upper area of the display screen and when operating the first detection unit,
The display content is changed in the same manner when an area corresponding to the second detection unit is operated among side areas located on the left and right of the display screen and when the second detection unit is operated. It is characterized by making it.

The input processing device according to the present invention enables at least two-dimensional input operation by moving and operating the hand performing key input on the keyboard device to the front or side of the key arrangement region. It is possible to control the display content of the screen with relatively fine details.
In addition, since the first detection unit and the second detection unit provided in the keyboard device correspond to the side region as long as it is the upper region of the detection panel provided on the display screen, By operating the side, the input operation can be performed with the same feeling as the operation of the top and side of the screen.

  In the input processing device of the present invention, it is preferable that the first detection unit and the second detection unit are formed on the same substrate.

  In addition, it is preferable that a continuous electrode is provided on the first detection unit and the second detection unit. In this configuration, since the continuous electrode can be used as a common drive electrode or detection electrode in the first detection unit and the second detection unit, the number of electrodes can be reduced, and drive control and detection control can be simplified. .

  For example, the change in the display content is the same when operated by traversing the upper region up and down and when operated by traversing the first detection unit back and forth. Moreover, the change of the display content is the same when the upper region is operated left and right and when the first detection unit is operated left and right.

  Alternatively, the change in the display content is the same when the operation is performed by traversing the lateral region from side to side and when the second detection unit is operated by traversing from side to side. Moreover, the change of the display content is the same when the side area is operated up and down and when the second detection unit is operated back and forth.

  In the input control device of the present invention, an operation signal generation unit is provided in the keyboard device, and the operation signal generation unit operates an upper region in the screen detection panel when an input key in the key arrangement region is pressed. A keyboard signal that emulates the operation signal when the operation is performed and the operation signal when the side region is operated is generated, and the operation signal generation unit includes the first detection unit and the second detection unit. When operated, the keyboard signal emulating the operation signal when the upper region is operated in the screen detection panel and the operation signal when the side region is operated is generated.

  In the present invention, since the display content of the display screen can be controlled by operating the first detection unit and the second detection unit provided in the keyboard device, various input operations can be performed without greatly releasing the input keys. It can be performed.

  In addition, the first detection unit and the second detection unit provided in the keyboard device correspond to the side region as long as it is the upper region of the detection panel provided on the display screen. By manipulating the direction, it is possible to perform an input operation with the same feeling in the same manner as operating the screen.

In the wiring region 13a, a plurality of wiring lines 15a are formed, each of which is individually connected to the independent electrode 14a.

  As shown in FIG. 4B, in the left detection unit 10c, the first hierarchy 11a is divided into a detection region 12c and a wiring region 13c. The detection region 12c and the wiring region 13c are elongated in the front-rear direction (Y direction). A plurality of independent electrodes 14c are formed in the detection region 12c. The plurality of independent electrodes 14c are formed at a constant pitch in the front-rear direction (Y direction). In the wiring region 13c, a plurality of wiring lines 15c are formed, each of which is individually connected to the independent electrode 14c.

  Similarly, in the right detection unit 10b, a detection region 12b and a wiring region 13b are formed on the first layer 11a (12b and 13b are not shown). In the detection region 12b, a plurality of independent electrodes 14b are formed at a constant pitch in the front-rear direction (Y direction). In the wiring region 13b, a plurality of wiring lines 15b that are individually connected to the independent electrode 14b are formed.

  As shown in FIG. 3B and FIGS. 4A and 4B, the continuous electrode 18 is formed in the second layer 11b. In the embodiment, three continuous electrodes 18 are provided.

  The independent electrodes 14a, 14b, 14c, the wiring lines 15a, 15b, 15c, and the continuous electrode 18 are formed by etching a copper foil, or are formed of silver paste.

  When the first layer 11a and the second layer 11b are overlaid, the continuous electrode 18 is overlaid on the detection regions 12a, 12b, and 12c of the first layer 11a. The detection area 12a of the front detection unit 10a is an elongated area, and the long side of the detection area 12a is arranged along the arrangement direction (X direction) of the input keys 6 of the key arrangement area 5. The detection area 12b of the right detection section 10b and the detection area 12c of the left detection section 10c are also elongated areas, and the long sides of the detection areas 12b and 12c are along the arrangement direction (Y direction) of the input keys 6 in the key arrangement area 5. Are arranged as follows. That is, the long side of each detection area is arranged along the edge of the keyboard device.

  The keyboard-mounted sensor 10 is a mutual capacitance type electrostatic sensor. The three continuous electrodes 18 and the plurality of independent electrodes 14a, 14b, and 14c are connected to a drive circuit and a detection circuit via a multiplexer. In the embodiment, three continuous electrodes 18 are used as drive electrodes and are connected to a drive circuit in order, and a plurality of independent electrodes 14a, 14b, and 14c are used as detection electrodes and are selected in order and detected circuit. Connected to. The order here refers to the plurality of independent electrodes 14a positioned in the front detection unit 10a being sequentially connected to the detection circuit, and the plurality of independent electrodes 14b positioned in the right detection unit 10b are sequentially connected at different timings. This means that the plurality of independent electrodes 14c that are selected and located in the left side detection unit 10c are selected in order and connected to the detection circuit.

  Since a capacitance is formed between each of the plurality of continuous electrodes 18 and each of the plurality of independent electrodes 14a, 14b, 14c, when a rectangular wave drive electrode is intermittently applied to any one of the continuous electrodes 18 A current flows through the independent electrodes 14a, 14b, and 14c at the rise and fall of the rectangular wave. When a person's finger, which is a conductor, approaches one of the detection regions 12a, 12b, and 12c, a current flows through the finger, so that the current flowing through the independent electrodes 14a, 14b, and 14c changes.

  In the sensor control unit of the keyboard-mounted sensor 10, information on which continuous electrode 18 is connected to the drive circuit, information on which of the plurality of independent electrodes 14a, 14b, and 14c is connected to the detection circuit, and Therefore, the approaching coordinates of the finger can be recognized as operation information in a two-dimensional direction on the XY coordinates.

In the detection area 12c, the approach position of a human finger or hand can be detected as a coordinate position in a two-dimensional direction.

  The keyboard-mounted sensor 10 detects the coordinate position when a finger or hand touches the surface of the panel surface of the main body case 4 that covers the detection areas 12a, 12b, and 12c. However, if the power applied to the continuous electrode 18 is set large, the coordinate position when the finger or hand is stopped or moved at a position away from the surface of the main body case 4 can be detected. In this case, since information about the height from the detection areas 12a, 12b, and 12c to the fingers and hands can be detected, the detection areas 12a, 12b, and 12c of the keyboard-mounted sensor 10 can detect operations in a three-dimensional direction. become.

  As a driving method of the keyboard-mounted sensor 10, the plurality of independent electrodes 14a, 14b, and 14c may be connected to the driving circuit in order, and the three continuous electrodes 18 may be connected to the detection circuit in order. Even in this driving method, the positions and movements of the fingers and hands can be acquired as at least two-dimensional information by the detection areas 12a, 12b, and 12c.

  As shown in FIG. 1, the display device 3 is provided with a display panel such as a liquid crystal color display panel, and the display screen 8 of the display panel is directed to the front side (Y2 side). A screen detection panel 9 is superimposed on the display screen 8. The screen detection panel 9 is a mutual capacitance type electrostatic detection panel. In the screen detection panel 9, a plurality of electrodes extending in the X direction and a plurality of electrodes extending in the Y direction are formed on a light transmitting film base material using a light transmitting conductive material such as ITO. The electrode extending in the X direction and the electrode extending in the Y direction are insulated from each other and intersect.

  In the screen detection panel 9, either the X-direction electrode or the Y-direction electrode is connected to the drive circuit, and either is connected to the detection circuit. The detection circuit detects a change in the detection current based on a change in capacitance change between the X-direction electrode and the Y-direction electrode, and the coordinate position on the display screen 8 is touched or approached. Can be detected.

  FIG. 5 is a block diagram showing the main configuration of the keyboard device 2 and the main configuration of the control processing unit 30 mounted on the personal computer 1.

  The keyboard device 2 is provided with an operation signal generation unit 21. The operation signal generation unit 21 includes a CPU and a memory. The operation signal generation unit 21 generates a keyboard signal Sk, which is format data having a predetermined number of bytes, from detection signals obtained from a plurality of key switches provided in the key array region 5 and detection signals of the touch pad 7. The

  The detection signal of the keyboard-mounted sensor 10 is given to the operation signal generator 21. The operation signal generation unit 21 analyzes the detection signal from the keyboard-mounted sensor 10 and generates a keyboard signal Sk that emulates the keyboard signal when the detection output of the key switch is a predetermined combination.

  The keyboard signal Sk generated by the operation signal generation unit 21 is given from the output interface 22 to the input interface 31 of the control processing unit 30. The output interface 22 and the input interface 31 are USB interfaces or the like.

  The control processing unit 30 is mainly composed of a CPU and a memory. The processing of the control processing unit 30 shown in FIG. 5 is executed based on previously stored software.

  The control processor 30 stores an operating system (OS) 32. The display driver 33 is controlled by the operating system 32, and the display content of the display screen 8 shown in FIG. 1 is controlled. The detection output of the screen detection panel 9 provided so as to overlap the display screen 8 is also given to the operating system 32, and the operating system 32 controls the display contents based on the detection output of the screen detection panel 9.

  Driver software 34 is installed in the control processing unit 30, and the keyboard signal Sk received by the input interface 31 is given to the driver software 34. In the driver software 34, a standard operation signal applied to the operating system 32 is generated from the keyboard signal Sk of a predetermined format sent from the operation signal generation unit 21 and notified to the operating system 32.

  As shown in FIG. 5, various application software 35 is installed in the control processing unit 30. The application software 35 is an Internet explorer, mail communication software, word processor, various calculation software, game software, or the like.

  In this embodiment, the keyboard device 2 and the control processing unit 30 constitute an input processing device.

  Next, an operation method of the personal computer 1 equipped with the input processing device of the present invention will be described.

  As shown in FIG. 1, the detection area (operation area) of the translucent screen detection panel 9 has a size covering almost the entire area of the display screen 8. In FIG. 1, the operation area of the screen detection panel 9 is an upper area 9a, a right side area 9b, a left side area 9c, a lower area 9d, and a center surrounded by the areas 9a, 9b, 9c, 9d. It is divided into region 9e. These areas may be set in advance by an external operation. Alternatively, the areas 9a, 9b, 9c, 9d, and 9e are not divided in advance, and in the operating system 32, which area is operated based on the detection signal of the XY coordinates obtained from the screen detection panel 9. May be determined based on the relationship with the application software 35 running at that time.

  In the processing operation of the control processing unit 30 shown in FIG. 5, when the operating system 32 is activated and an initial image immediately after activation is displayed on the display screen 8, or an image relating to software that is already being executed is displayed. As shown in FIG. 1, an operation is performed in which the finger or hand touches or approaches the right side of the display screen 8 to cross the left direction as indicated by the arrow O <b> 1. When the detection signal is notified to the operating system 32, the display driver 33 is controlled by the operating system 32, and a menu bar M1 called a charm bar appears on the right side of the display screen 8 as shown in FIG.

  Further, the menu bar M1 can be displayed on the display screen 8 in the same manner by operating a plurality of input keys 6 instead of operating the screen detection panel 9. Further, as shown in FIG. 2, a finger or a hand is touched or brought close to the right side detection unit 10b located on the right side of the key arrangement region 5 of the keyboard-mounted sensor 10 and crossed leftward as indicated by an arrow E1. The menu bar M1 can also be displayed on the right side of the display screen 8 as shown in FIG.

  Details of the processing operation when displaying the menu bar M1 on the right side of the display screen 8 are as follows.

  In the operating system 32, when the right side area 9b of the screen detection panel 9 is operated in the direction of the arrow O1, control is performed to display the menu bar M1 shown in FIG. On the other hand, when a plurality of input keys 6 in the key array region 5 are operated in a predetermined combination, a keyboard signal Sk is generated by the operation signal generation unit 21 based on the operation and provided to the driver software 34. At this time, the driver software 34 generates an instruction signal that emulates the signal when the operation of the arrow O <b> 1 is performed on the screen detection panel 9 and gives it to the operating system 32.

  Furthermore, in the keyboard device 2, when the operation indicated by the arrow E <b> 1 is performed on the right side detection unit 10 b of the keyboard-mounted sensor 10, the operation signal generation unit 21 has a plurality of input keys 6 in a predetermined combination. A keyboard signal Sk equivalent to the keyboard signal when operated is generated and given to the driver software 34.

  With this process, when the plurality of input keys 6 are operated in a predetermined combination and when the operation indicated by E1 in FIG. 2 is performed, the operating system 32 is operated by O1 in FIG. The same display control is performed.

  In this control, when the right detection unit 10b of the keyboard-mounted sensor 10 is operated like E1, the operation signal is not given to the operating system 32 through a special route, but is the same as when the keyboard is operated. It is given to the driver software 34 from the operation signal generator 21 through the signal path. Therefore, if the personal computer uses the same driver software 34, the keyboard-mounted sensor 10 can be mounted for general use.

  As shown in FIG. 1, the right side of the display screen 8 is operated in the direction of the arrow O1, and the right side of the key arrangement area 5 is operated in the direction of the arrow E1 as shown in FIG. Since the movement of the hand is similar, if the operator knows that the menu bar M1 appears on the display screen 8 when the operation of O1 in FIG. 1 is performed, the operator can perform the same operation on the keyboard device 2. The menu bar M1 can be displayed. Moreover, since the hand operating on the key arrangement area 5 can be operated without greatly separating from the keyboard device 2, it is easy to operate.

  When the menu bar M1 shown in FIG. 6 is displayed, if a finger touches any of the display locations of the menu displays m1, m2, m3, m4, and m5 included in the menu bar M1 on the display screen 8, the touch is performed. The application software corresponding to the displayed menu will be launched. On the other hand, on the right side detection unit 10b of the keyboard-mounted sensor 10 shown in FIG. 2, by touching a position corresponding to the menu display m1, m2, m3, m4, m5 and performing a tap operation or a double tap operation, Either menu display can be selected.

  In this case, as shown in FIG. 6, when the finger touches or approaches the display area of the menu bar M1 on the display screen 8 and moves in the arrow O2 direction, the menu displays m1 and m2 facing the finger , M3, m4, and m5 are preferably highlighted in order, for example. With this setting, when the finger touching or approaching the right detection unit 10b in the keyboard device 2 is moved in the direction of the arrow E2, the menu display m1, m2, m3, m4, m5 is similarly performed. It is possible to change the display such as highlighting in order, which makes it easy to understand which menu display is selected.

  When the menu bar M1 is displayed, when the touch pad 7 or a mouse (not shown) is operated, the cursor displayed in the menu bar M1 moves up and down to display the menu displays m1, m2, and so on. One of m3, m4, and m5 may be selected, and the menu display may be selected by clicking the touch pad 7 or the mouse. In this setting, as shown in FIG. 2, when the finger touching or approaching the right detection unit 10b of the keyboard-mounted sensor 10 is moved in the direction of the arrow E2, the cursor is similarly moved up and down in the menu bar M1. Then, one of the menu displays m1, m2, m3, m4, and m5 is selected, and the menu display is selected by performing a tap operation or a double tap operation.

  Also at this time, the operation signal generation unit 21 generates an equivalent keyboard signal Sk when the touch pad 7 or the mouse is operated and when the keyboard-mounted sensor 10 is operated, and gives it to the driver software 34. It is done.

  When the start menu is selected from the menu displays m1, m2, m3, m4, and m5, the start screen shown in FIG. On the start screen shown in FIG. 7, a plurality of application menus Ma, Mb, Mc, Md,... Are displayed side by side. In the screen detection panel 9 shown in FIG. 1, when a finger touches a location where an application menu to be selected is displayed, application software corresponding to the menu is activated. This can also be executed by using the touch pad 7 or the mouse and moving the cursor displayed on the display screen 8 over the application menu to be selected and clicking.

  When the start screen is displayed on the display screen 8, as shown in FIG. 1 and FIG. 7, a finger or hand touches or approaches the left side region 9c of the screen detection panel 9 as indicated by an arrow O3. When an operation that crosses in the right direction or the left direction is performed, the display image moves in the operation direction or changes such that the display image is turned in the operation direction. For example, when an operation is performed in the right direction along the arrow O3, the application menus Ma, Mb, Mc, Md,... Move to the right side or change so as to turn to the right side, and are arranged in the next hierarchy. An array of application menus is newly displayed. When an operation is performed to the left along the arrow O3, the application menu Ma, Mb, Mc, Md,... Moves to the left side or changes to turn left, and another application arranged in the next layer A new array of menus is displayed.

  Also, when an operation along the arrow O3 is performed while an Internet image, a character input screen, or the like is displayed on the display screen 8, the screen moves to the left or right in the same manner, or moves so as to turn up. Then, the screen is switched to the screen of the next hierarchy.

  On the other hand, as shown in FIG. 2, when a finger or hand is brought close to the left side detection unit 10c of the keyboard-mounted sensor 10 and operated to cross the left side detection unit 10c as indicated by E3, The display content changes so that the display content of the display screen 8 moves to the right or left, or turns.

  The operation of moving the display content of the display screen 8 to the left or right or turning it up is performed in the same manner when a plurality of input keys 6 in the key arrangement area 5 are combined and operated. Therefore, the operation signal generation unit 21 generates the same keyboard signal Sk as that operated by combining the input keys 6 when the operation of the arrow E3 in FIG. Also in this case, since the operation on the keyboard device 2 and the operation on the display screen 8 correspond to each other, the operation becomes easy.

  Next, as shown in FIG. 1, when the upper region 9 a of the screen detection panel 9 is touched or brought close to the upper region 9 a and an operation of crossing the upper region 9 a downward is performed as indicated by an arrow O <b> 4, FIG. As shown, a horizontal menu bar M2 is displayed at the top of the display screen 8. Similarly, as shown in FIG. 2, a finger or a hand touches or approaches the front detection unit 10a of the keyboard-mounted sensor 10, and the front detection unit 10a is crossed to the front side as indicated by an arrow E4. The horizontal menu bar M2 also appears when performing.

  As shown in FIG. 8, the horizontal menu bar M2 is provided with a plurality of menu displays ma, mb, mc, and md spaced in the X direction. Also at this time, when the finger touches any of the display locations of the menu display ma, mb, mc, md on the display screen 8, the screen detection panel 9 detects this, and the operating system 32 displays the menu display ma, mb. , Mc, md is recognized as being selected, and an application corresponding to the menu display is activated.

  Further, when the horizontal menu bar M2 is displayed, as shown in FIG. 2, an operation of moving a finger or a hand in contact with or approaching the front detection unit 10a of the keyboard-mounted sensor 10 in the direction of the arrow E5. The menu display ma, mb, mc, md is highlighted in order and the display state is switched. A menu display can be selected by performing a tap operation or a double tap operation when the display state of any menu display changes. Alternatively, when the operation of the arrow E5 shown in FIG. 2 is performed, the cursor displayed in the horizontal menu bar M2 moves, and the cursor indicates one of the menu displays ma, mb, mc, and md. The menu display may be selected by performing a tap operation or a double tap operation on the front detection unit 10a.

  As described above, when the operations O1, O3, and O4 are performed on the side areas 9b and 9c and the upper area 9a of the screen detection panel 9 provided on the display screen 8, as shown in FIG. Since the same input can be performed on the keyboard-mounted sensor 10 when the operations E1, E3, and E4 are performed, the input operation on the keyboard-mounted sensor 10 is easy. Further, the input operation can be performed with the same feeling as operating on the display screen 8 without moving the hand greatly during the operation of the key array region 5.

  FIG. 8 shows a state in which two fingers that have touched or approached the display screen 8 are operated along the O5 direction in directions toward and away from each other.
