Description

  The present invention relates to an input processing system that performs processing associated with a selection icon that has been selected and confirmed based on an operation in which a user selects and confirms one of the selection icons displayed on a display screen of a display device.

  2. Description of the Related Art Conventionally, there exists an input processing system that performs processing associated with a selection icon that has been selected and confirmed based on an operation in which a user selects and confirms one of the selection icons displayed on the display screen of the display device.

  As such an input processing system, for example, there is a personal computer that executes a program indicated by an icon on the basis of a selection / confirmation operation (corresponding to a double click) of an icon on the screen with a mouse. Also, for example, based on the selection confirmation operation (corresponding to a double tap) of a 50 sound icon on the screen using a touch panel superimposed on the display screen, the input of the destination is accepted and the route to the destination is guided. There is a car navigation system.

  In such an input processing system, there is a demand for reducing the movement of the line of sight and the movement of the focus when the user looks at the screen display performed by the input processing system. For example, in a car navigation device, if the driver's line-of-sight movement and focus movement are large, it may affect the forward confirmation, which is not preferable.

  In order to reduce such a user's line-of-sight movement and focal point movement, an input processing apparatus is conventionally arranged in a car navigation apparatus or the like. However, as a result, the user's operation hand does not reach the touch panel, and an input device that can be operated at a position away from the input processing device, such as a remote control terminal (hereinafter referred to as a remote control), is used.

Moreover, the user touching the operation surface is a concept including direct contact using a user's finger or the like and indirect contact using a pen or the like.

  In addition, “highlighted display” refers to a display that can easily distinguish the one selected icon from the other selected icon.

  According to a second aspect of the present invention, in the input processing system according to the first aspect, the highlighted display is a discolored display of a selection icon.

  The invention according to claim 3 is the input processing system according to claim 1 or 2, wherein the highlighting control means is configured such that a position on the display screen specified by the specifying means is selected from the selection icons. When included in one selectable area, the one selection icon is highlighted on the display device.

  According to a fourth aspect of the present invention, in the input processing system according to any one of the first to third aspects, the highlight display control means is configured such that the position on the display screen specified by the specifying means is: When it is not included in any selectable area of the selection icon, a pointer is displayed on the display device at a position on the display screen.

  As a result, when the pointer is displayed on the display screen, it is possible to clearly confirm that the position of the operation surface that the user is currently touching is a position that does not correspond to any selection icon, Based on the position where the pointer is displayed, it is possible to determine in which direction the contact portion of the operation surface should be moved.

  According to a fifth aspect of the present invention, in the input processing system according to any one of the first to fourth aspects, the highlighting control means is a predetermined time after the user stops touching the operation surface. The highlighting is continued based on the position on the display screen specified by the specifying unit immediately before the touch is stopped.

  As a result, if the user once stops touching the operation surface and then performs an operation for confirming the selection within a predetermined time, the selection of the selected icon is successfully confirmed, thus improving the operability for confirming the selection. To do.

  According to a sixth aspect of the present invention, in the input processing system according to any one of the first to fifth aspects, the user operation for confirming selection of the highlighted selection icon is the operation described above. It is a multi-tap of a surface.

  FIG. 2 shows a hardware configuration of the car navigation apparatus 1. The car navigation device 1 includes a position detector 11, an internal memory control device 16, an operation switch group 17, an external memory control device 19, a display device 20, a communication module 28, and a control circuit 18 connected thereto.

  The display device 20 has a display screen such as a liquid crystal display, and displays the video on a display surface such as a liquid crystal display in response to an input of a video signal from the control circuit 18. The display surface is fixed to the front surface of the dashboard 3 together with the other parts of the car navigation device 1.

  The operation switch group 17 includes input devices such as a plurality of mechanical switches provided around the display surface of the display device 20 and a touch panel provided so as to overlap the display surface. And a signal based on the touch on the touch panel is output to the control circuit 18.

  The communication module 28 receives a wireless signal based on infrared rays, Bluetooth, or the like from the touch input device 2 based on a user operation, and performs predetermined wireless communication such as amplification, frequency conversion, demodulation, A / D conversion, and the like on the received signal. Processing according to the protocol is performed, and a signal resulting from the processing is output to the control circuit 18. In addition, the communication module 28 performs processing according to a predetermined wireless communication protocol such as D / A conversion, modulation, frequency conversion, amplification, and the like on the data input from the control circuit 18, and outputs a result signal to the touch input device. Output to 2.

Have. These sensors 12 to 15 output information for specifying the current position based on their properties to the control circuit 18. The position detector 11 may further include a steering rotation sensor, a wheel sensor for each drive wheel, and the like (not shown).

  The internal memory control device 16 includes a nonvolatile storage medium such as an HDD (Hard Disk Drive), and reads data from the nonvolatile storage medium based on a control command from the control circuit 18 and data if possible. Control writing of. Information stored in the nonvolatile storage medium includes so-called map matching data for improving the accuracy of position detection, various data including map data and landmark data, and a program for operation of the car navigation device 1. Etc.

  The external memory control device 19 controls data reading and data writing to a removable external storage medium 31 such as a DVD-ROM, a memory stick, or a memory card if possible. The information stored in the external storage medium 31 includes data for map matching, additional data for map data, landmark data, and the like.

  The control circuit 18 is configured as a normal computer, and includes a CPU, a ROM, a RAM, a flash memory, an I / O, and a bus line for connecting these configurations. The control circuit 18 executes a program for the operation of the car navigation device 1 read from the ROM, the internal memory control device 16, and the external storage medium 31, and reads information from the ROM, RAM, and flash memory at the time of execution. , Writes information to the RAM and flash memory, and exchanges signals with the position detector 11, operation switch group 17, external memory control device 19, display device 20, communication module 28, etc. via I / O. .

  When the car navigation apparatus 1 is activated, the CPU of the control circuit 18 reads out and executes a boot program, an operating system (hereinafter referred to as OS) from the ROM, and performs hardware control and process management based on the OS. . Processes that operate on the OS include a menu program, a destination setting program, a route search program, a map display program, and other programs.

  If the CPU of the control circuit 18 needs to specify the current position in the execution of these programs, it is based on a signal for specifying the current position output from the sensors 12 to 15 of the position detector 11. The current position is calculated. At this time, since the outputs from the various sensors 12 to 15 have errors having different properties, the current position in the CPU of the control circuit 18 is specified in a complementary manner by using a plurality of sensors. .

  In the following, the operation in which the CPU reads and executes the program will be described as the operation of the executed program itself.

  The menu program displays various programs that run on the OS hierarchically according to the function and purpose of the program, and a selection icon is displayed as a menu. The menu program is associated with a selection icon that the user has confirmed to select. Start the program execution. Note that menu display is performed by outputting image data of the menu to the display device 20, and selection by the user is performed by a selection operation (cursor movement, Detection is performed based on a signal input to the control circuit 18 by pressing a confirmation button or the like.

  The destination setting program is a program for setting the destination, and causes the display device 20 to display the display device 20 to prompt the user to input the destination. As a result, the destination using the touch input device 2 or the operation switch group 17 by the user is displayed. The above setting is realized by storing the destination in the RAM of the control circuit 18 based on the ground input.

  As one method for inputting the destination, a character string of the name of the facility at the destination can be input. That is, when the destination setting program receives a character string input of the name of the destination by the user, the destination setting program is included in the map data of the internal memory control device 16 in advance, or separately created by the user and stored in the internal memory control device 16. The facility having the name is searched from the point information (having information on the name of the point and the position of the point), and the facility corresponding to the result of the search is set as the destination.

  In order to realize such a function, the destination setting program causes the display device 20 to display a 50-sound input screen for facilitating user input character strings. An example of this 50 sound input screen is shown in FIG.

  The 50 sound input screen 51 includes a 50 sound part 52, an input character string display part 53, a completion icon 54, a correction icon 55, a return icon 56, and a number display part 57.

  The 50 sound part 52 is composed of a plurality of character icons as input candidate characters arranged in a normal 50 sound table format. These character icons are selection icons, and by selecting one of them by a user operation, the character indicated by the selection icon whose selection has been confirmed is added to the input character string display unit 53.

  The completion icon 54 is a selection icon. When the selection of the selection icon is confirmed, the destination input is completed. At this time, the character string displayed on the input character string display unit 53 is the name of the facility at the destination. It becomes.

  The correction icon 55 is a selection icon. When the selection of the selection icon is confirmed, the last character of the character strings displayed on the character string display unit 53 is deleted from the display on the input character string display unit 53. Is done.

  The return icon 56 is a selection icon. When the selection of the selection icon is confirmed, the character input is forcibly terminated, and the screen before the 50-sound input screen 51 for displaying the character is displayed is displayed again. Do.

  The route search program automatically selects an optimum route from the current position to the destination set by the destination setting program, and causes the display device 20 to display the selected route as a guide route. A Dijkstra method or the like is known as a method for automatically setting an optimum route.

  The map display program includes a vehicle current position mark based on the specified current position information, map data read using the internal memory control device 16 or the external memory control device 19, and additional data such as a guidance route formed by the route search program. And are displayed on the display surface of the display device 20.

  In the program executed by the control circuit 18 as described above, when the selection icon is displayed on the display device 20, the control circuit 18 touch-inputs information on selectable areas in the display device 20 of each selection icon. In order to notify the apparatus 2, a signal of the information is output to the communication module 28. The selectable area of the selection icon is determined based on the position of the selection icon in the display screen. Specifically, first, a portion where the selection icon is displayed is a selectable area of the selection icon. Further, the positions of the gaps between two adjacent selection icons (for example, “A” and “KA”, “YA” and “YU”, etc. in FIG. 3) are the closest of the two selection icons. Belongs to the selectable area. A position far from any selected icon (for example, near the lower left corner of the 50-sound input screen 51, near the upper left side, etc.) does not belong to the selectable area of any selected icon. Further, as the information on the selection area, information consisting of a combination of the name of each selection icon and the coordinate range on the display screen of the selection area of the selection icon is used.

  Further, in the program executed by the control circuit 18 as described above, when the selection icon is not displayed on the display device 20, in order to notify the touch input device 2 of the information to that effect, a signal of the information is sent to the communication module 28. Output.

  FIG. 4 shows the configuration of the touch input device 2. The touch input device 2 includes an antenna 41, a touch panel 42, a RAM 43, a ROM 44, a wireless unit 45, a CPU 46, and the like.

 The RAM 43 is a readable / writable volatile memory, and the ROM 44 is a read-only nonvolatile memory. In the ROM 44, programs and the like that are read and executed by the CPU 46 are stored in advance. The RAM 43 is used as a storage area for temporarily saving the program when the CPU 46 executes the program stored in the ROM 44.

  The wireless unit 45 performs processing according to a predetermined wireless communication protocol such as amplification, frequency conversion, demodulation, A / D conversion, and the like on the signal received by the antenna 41 and outputs the result to the CPU 46. In addition, the wireless unit 45 performs processing according to a predetermined wireless communication protocol such as D / A conversion, modulation, frequency conversion, and amplification on the data input from the CPU 46, and outputs the resulting signal to the antenna 46. . Thereby, a signal is transmitted from the antenna 41 to the communication module 28 by predetermined wireless communication. Examples of the predetermined wireless communication include infrared communication and Bluetooth.

  The touch panel 42 outputs a signal based on the user's contact operation to the CPU 46. FIG. 5 shows a front view of the touch panel 42. The touch panel 42 has an operation surface 47 that is a rectangular (for example, 46 mm wide × 36 mm long) input area on the front surface. While an operation tool such as a human finger or a pen is touching any part of the operation surface 47 with a predetermined force (for example, 50 gram weight), the touch panel 42 is 2 based on the touched position. The signal indicating the dimension coordinate value is continuously output to the CPU 46. Specifically, as the two-dimensional coordinate value, there is a coordinate value of the touched position in an orthogonal coordinate with the vertical direction in the operation surface 47 of FIG. 5 as the Y-axis direction and the horizontal direction as the X-axis direction.

  The CPU 46 reads a predetermined program from the ROM 44 and executes it. The CPU 46 operates based on the program to be executed, the signal from the wireless unit 45, and the signal from the touch panel 42. Then, the CPU 46 reads out the data stored in the RAM 43 and ROM 44 as necessary for the operation, stores the data in the RAM 43, and outputs a signal for wireless transmission to the wireless unit 45.

  The operation for confirming selection of the selection icon in the car navigation device 1 and the touch input device 2 configured as described above will be described below.

  FIG. 6 shows a flowchart of a touch panel operation program executed by the CPU 46 of the touch input device 2 for such selection confirmation.

  This program is executed by the CPU 46 when a user touches the operation surface 47 of the touch panel 42 with a finger or the like with a predetermined force or more to output a two-dimensional coordinate value signal from the touch panel 42 to the CPU 46. .

  First, in step 610, the finger touch screen position is specified. Specifically, the coordinate values X and Y of the touched portion on the operation surface 47 are read from the signal currently input from the touch panel 42, and the display screen of the corresponding display device 20 is read from the coordinate values X and Y. The coordinate values are converted into X ′ and Y ′. FIG. 7 shows the correspondence between the position on the operation surface 47 and the position on the display screen 60 of the display device 20.

Corresponding lines 61 to 64 indicate positions on the operation surface 47 and positions on the display screen 60 corresponding to the positions. Thus, the four corners of the operation surface 47 correspond to the four corners of the display screen 60, respectively. As a correspondence relationship between the portions other than the four corners, a portion on the operation surface 47 and a portion on the display screen 60 corresponding to the portion have the same relative positions from the four corners. Specifically, vectors up to four corners for each of the corresponding lines 61, 62, 63, 64 on the operation surface 47 are represented by a, b, c, d, and the corresponding lines 61, 62, 63, When vectors up to four corners for each of 64 are represented by a ′, b ′, c ′, d ′,
p {qa + (1-q) b} + (1-p) {qc + (1-q) d}
The part on the operation surface 47 represented by (where 0 <p, q <1)
p {qa '+ (1-q) b'} + (1-p) {qc '+ (1-q) d'}
Corresponds to the part on the display screen 60 represented by That is, the conversion from the coordinate values X and Y on the operation surface 47 to the coordinate values X ′ and Y ′ on the display screen 60 is a linear conversion in which the four corners are matched. Note that the conversion coefficient in the linear conversion in step 610 is read out from the ROM 44 in advance and used.

  Next, in step 620, it is determined whether or not the touch position is on the selection icon. Specifically, the coordinate values X ′ and Y ′ on the display screen 60 identified in step 610 are compared with the information on the selectable area of the selection icon on the display screen 60 received from the control circuit 18 as described above. Then, it is determined whether or not the specified coordinate values X ′ and Y ′ are included in the selectable area of any selection icon included in the information of the selectable area. If the touch position is on the selected icon, the process proceeds to step 640, and if not, the process proceeds to step 630.

  In step 630, pointer display and selection icon non-emphasis processing are performed. Specifically, a signal for requesting that the pointer image be superimposed and displayed at a position corresponding to the sitting values X ′ and Y ′ specified in step 610 on the display screen currently displayed on the display device 20. Is transmitted to the control circuit 18 via the wireless unit 45. By receiving such a request signal, the control circuit 18 outputs a control signal to the display device 20 so that the pointer is displayed at the requested position on the currently displayed image. When the display device 20 highlights a part of the selected icon, a control signal for stopping the highlighted display is output. Therefore, the request signal described above is a signal for displaying a pointer and stopping highlighting of the selected icon.

  However, if the specified coordinate values X ′ and Y ′ are the position of the input character string display unit 53 on the display screen 60 and the vicinity thereof, the pointer is not displayed at that position. In such a case, a pointer is displayed near the position of the coordinate values X ′ and Y ′ and at the input character string display portion 53 and a place not in the vicinity thereof. This is a process for preventing the user from being misunderstood that characters can be directly input to the input character string display unit 53.

  In step 640, pointer deletion and selection icon highlight display processing are performed. Specifically, in step 620, a signal requesting to highlight the selection icon included in the selectable area is transmitted to the control circuit 18 via the wireless unit 45. By receiving such a request signal, the control circuit 18 outputs a control signal to the display device 20 so as to highlight the requested selection icon on the currently displayed image. When the display device 20 displays a pointer, a control signal for stopping the display is output. Therefore, the request signal described above is a signal for highlighting the selected icon and stopping the pointer display.

  FIG. 8 is an explanatory diagram showing an example of highlighting of pointers and selection icons on the display screen 60. If the seat values X ′ and Y ′ specified in step 610 are near the lower left corner in the display screen 60 by the processing in steps 620 to 640 described above, for example, the seat values X ′ and Y ′ are located at the positions of the seat values X ′ and Y ′. A pointer 65 is displayed. Thus, the pointer is a display for emphasizing the positions of the sitting values X 'and Y' on the display screen. Further, for example, the sitting values X ′ and Y ′ specified in step 610 are within the selectable area of the “fu” selection icon 66 in the display screen 60 (that is, the display area of the “fu” selection icon and its surroundings). If it is, the selection icon 66 is highlighted. Examples of the highlight display include a display in which the selected icon 66 has a different color from the other selected icons, such as a highlight display of the selected icon 66, that is, a discolored display.

  In this explanatory diagram, the pointer 65 and the highlighting of the selection icon 66 are displayed at the same time. However, this is displayed for convenience of explanation, and it is actually displayed at the same time. Absent.

  Following steps 630 and 640, processing proceeds to step 645, where the timer value used in step 670 is reset. Specifically, the current time is stored in a predetermined area of the RAM of the control circuit 18.

  Next, in step 650, it is determined whether or not there is a touch. Specifically, it is determined whether or not there is an input of a two-dimensional coordinate value signal indicating that the operation surface 47 is currently being touched from the touch panel 42. Note that it is determined that there is a touch even when there is a double tap described later. If so, the process proceeds to step 680, and if not touched, the process proceeds to step 670.

  In step 670, it is determined whether or not a certain time has elapsed. Specifically, the current time is compared with the time stored in a predetermined area of the RAM of the control circuit 18 in step 645. If this time exceeds a predetermined time (for example, 5 seconds), a certain time has elapsed. If it does not exceed, it is determined that a certain time has not elapsed. If the fixed time has not elapsed, the process returns to step 650, and if it has elapsed, the process proceeds to step 675.

  In step 675, processing for transition to the original screen is performed. Specifically, a signal requesting to display the screen before displaying the display screen 60 is transmitted to the control circuit 18 of the car navigation device 1 via the wireless unit 45. By receiving such a request signal, the control circuit 18 controls the display device 20 to display the previous screen. Then, after step 675, the process ends.

  In step 680, it is determined whether there is a double tap operation. The double tap operation refers to an operation of touching the operation surface 47 twice within a predetermined short time (for example, 0.5 seconds). Specifically, from the touch panel 42, a two-dimensional coordinate value signal indicating that the operation surface 47 is touched, the input of the signal disappearing, and a two-dimensional coordinate value indicating that the operation surface 47 is touched. It is determined whether or not the signal input is continued in this order within a short time. If there is a double tap, the process proceeds to step 690; otherwise, the process returns to step 610.

  In step 690, processing for selection confirmation / screen fiber is performed. Specifically, the process associated with the selection icon having the seat values X ′ and Y ′ specified in step 610 as selectable areas is executed in the control circuit 18 of the car navigation apparatus 1 via the wireless unit 45. A request signal is output. However, if the sitting values X ′ and Y ′ specified in step 610 are not selectable areas of any selection icon, the above-described signal is not transmitted. By receiving such a request signal, the control circuit 18 starts execution of the associated process and causes the display device 20 to display according to the process. Then, after step 690, the process ends.

  By the operation of the touch panel operation program and the control circuit 18 as described above, the display of the display device 20 is displayed from the two-dimensional coordinate values X and Y based on the touch position on the operation surface 47 input from the touch panel 42 in step 610. The coordinates X ′ and Y ′ on the screen are specified.

  In Steps 620 to 640, if the position on the display screen corresponding to the touch position is a selectable icon selectable area, the selected icon is highlighted by the discoloration display. If the position on the display screen is not a selectable area of any selection icon, a pointer is displayed at the position.

  Then, the process associated with the selected icon is performed in the control circuit 18 by the process of steps 680 and 690 based on the user operation for confirming the selection of the highlighted selection icon, that is, the double tap operation. Is called.

  Thus, in the input processing system including the car navigation device 1 and the touch input device 2, when the user touches a part of the operation surface 47 of the touch input device 2 at hand, the two-dimensional coordinate value based on the touched position. Is output to the CPU 46, the CPU 46 specifies the position on the display screen based on the two-dimensional coordinate value, and further, based on the specified position, a plurality of signals displayed on the display screen of the display device 20 are displayed. One of the selected icons is highlighted, and a process associated with the selected icon is performed by the control circuit 18 based on the confirmation operation of the user.

  Thus, when the user touches the operation surface 47 of the touch input device 2 at hand, the selection icon on the display screen based on the touched position on the operation surface is highlighted, and the user operates When the contact portion is moved on the surface, the highlight target in the plurality of selection icons is moved accordingly.
