However, the present invention is not limited by this embodiment. The input system, the input method, and the input program according to the present invention can be used for any purpose. In the following embodiment, an example applied to a car navigation system is shown.

(Constitution)
First, the configuration of the input system according to the embodiment will be described. FIG. 1 is a block diagram illustrating an input system according to an embodiment. As illustrated in FIG. 1, the input system 1 includes a touch panel 10, a display unit 11, a control unit 12, and a data recording unit 13.

(Configuration-touch panel)
The touch panel 10 is an input unit having a contact detection surface 10a superimposed on the front display 11a described later. The touch panel 10 is formed to be transparent or translucent, and is provided on the front surface of the front display 11a so as to overlap the display surface of the front display 11a. As the touch panel 10, for example, a known touch panel having a contact detection surface by a resistance film method or a capacitance method can be used.

(Configuration-display section)
The display unit 11 is a display unit that displays various information based on the control of the control unit 12, and includes a front display 11a and a rear display 11b. The front display 11a and the rear display 11b are configured using flat panel displays such as a known liquid crystal display and organic EL display.

  FIG. 2 is a perspective view schematically showing the arrangement of the front display 11a and the rear display 11b. As shown in FIG. 2, the front display 11a and the rear display 11b are superposed and spaced apart from each other. Here, “front” means the display direction (the direction of the arrow in FIG. 2) on the front display 11a and the rear display 11b. That is, the front display 11a is superposed on the display surface side of the rear display 11b.

  The front display 11a is configured as a display that can transmit the display of the rear display 11b (for example, a transparent liquid crystal display or a transparent organic EL display). Thereby, the display of the rear display 12 can be visually recognized through the front display 11. That is, the display on the rear display 11b can be transmitted through the front display 11a, or the display on the rear display 11b can be superimposed on the display on the front display 11a.

  When the rear display 11b is a liquid crystal display, as shown in FIG. 2, a backlight is provided behind the liquid crystal panel constituting the rear display 11b. The light emitted from the backlight is emitted to the front of the rear display 11b via the liquid crystal panel of the rear display 11b and reaches the front display 11a, and further to the front of the front display 11a via the front display 11a. proceed. Thus, by using the light incident on the front display 11a from the rear display 11b as the backlight of the front display 11a, the display on the front display 11a can be visually recognized. In addition, when the rear display 11b is configured using an organic EL display, each pixel of the organic EL display emits light, and thus a backlight is not necessary.

  In addition, a plurality of display layers (soft layers) can be virtually superimposed and displayed on the rear display 11b by software. For example, as illustrated in FIG. 2, two display layers (frontmost layer and rear layer) virtually superimposed on the rear display 11b can be displayed. Below, the case where the screen (front display screen) displayed on the front display 11a and the screen (back display screen) displayed on the rear display 11b are displayed in a superimposed manner will be described. However, the present invention can also be applied to a display system having only one display. That is, on the display, as described above, the screen displayed on the front display layer (front display screen) and the screen displayed on the rear display layer (rear display screen) are virtually superimposed by software. May be.

  FIG. 3 is a front view illustrating the display on the front display 11a and the rear display 11b, FIG. 3 (a) illustrates the display on the front display 11a, and FIG. 3 (b) illustrates the display on the rear display 11b. FIG. 3 and FIG. 3C are views exemplifying displays when viewed from the front of the front display 11a and the rear display 11b arranged in a superimposed manner. For example, as shown in FIG. 3A, a home screen including various icons is displayed on the front display 11a. In addition, the area other than the icon in the front display 11a is set to be transparent (for example, when the front display 11a is configured using a liquid crystal display, the color of the area other than the icon is set to “white”. ). As shown in FIG. 3B, a map is displayed on the rear display 11b. In this case, as shown in FIG. 3C, in the area other than the icon in the front display 11a, the map displayed on the rear display 11b can be displayed through the front display 11a. In the area of the icon on the front display 11a, the map displayed on the rear display 11b can be displayed by being superimposed on the icon displayed on the front display 11a (ie, the icon on the front display 11a and the rear The map on the display 11b appears to overlap).

(Configuration-control unit)
Returning to FIG. 1, the control unit 12 is a control unit for controlling each unit of the input system 1, and specifically, a CPU and various programs interpreted and executed on the CPU (basic control programs such as an OS). And a computer configured to include an internal memory such as a RAM for storing the program and various data. In particular, the input program according to the present embodiment is substantially installed in the input system 1 via an arbitrary recording medium or network, thereby substantially configuring each unit of the control unit 12.

  The control unit 12 includes a determination unit 12a, an input control unit 12b, and a display control unit 12c in terms of functional concept. The determination unit 12a is a determination unit that determines the type of input detected on the contact detection surface 10a. The input control unit 12b is an input control unit that performs predetermined control for receiving either an input corresponding to the screen displayed on the front display 11a or an input corresponding to the screen displayed on the rear display 11b. . The display control unit 12c is a display control unit that performs display control of the front display 11a and the rear display 11b. Details of processing executed by each unit of these control units 12 will be described later.

(Configuration-Data recording part)
The data recording unit 13 is a recording unit that records programs and various data necessary for the operation of the input system 1, and is configured using a magnetic recording medium such as a hard disk (not shown) as an external storage device, for example. ing. However, any other recording medium including a semiconductor storage medium such as a flash memory or an optical recording medium such as a DVD or a Blu-ray disk can be used instead of or together with the hard disk.

  The data recording unit 13 includes an input type table 13a. The input type table 13a stores input type information that specifies screen type information and input type information that specifies input types that can be received in correspondence with various types of screens in association with each other. Means. FIG. 4 is a table illustrating information stored in the input type table 13a. As shown in FIG. 4, information corresponding to the items “screen type” and “input type” is stored in the input type table 13a in association with each other. The information stored corresponding to the item “screen type” is screen type information that identifies the type of the screen. ("Home", "Audio" etc. in FIG. 4). The information stored corresponding to the item “input type” is input type information that identifies the type of input that can be accepted in correspondence with the operation image displayed on the front display 11a or the rear display 11b (in FIG. 4). “Pressing the switch”, “Multi-touch”, “Trace”, etc.).

(processing)
Next, input processing executed by the input system 1 configured as described above will be described. FIG. 5 is a flowchart of the input process (in the following description of each process, step is abbreviated as “S”). This input processing is repeatedly executed when what is displayed as the whole of the front display 11a and the rear display 11b is determined by, for example, a navigation application or an HMI (Human Machine Interface) application (both not shown). The

  As shown in FIG. 5, when the input process is started, the display control unit 12c performs display control of the front display 11a (SA1). For example, the display control unit 12c determines, as a display mode of the front display 11a, an image, a character, or the like (icon in the example of FIG. 3) to be displayed on the front display 11a in the display determined by the navigation application or the HMI application. . Here, the “display mode” is a concept including the display state and contents on the front display 11a and the rear display 11b, and more specifically, the brightness, color, shape, and type of display on the front display 11a and the rear display 11b. In addition, it includes contents such as images, characters, and information as the display. Then, image data such as images and characters included in the determined display mode is acquired from the data recording unit 13, and display data for displaying each image data at a predetermined position on the front display 11a is generated. Based on the display data generated in this way, display control of the front display 11a is performed.

  Subsequently, the display control unit 12c performs display control of the rear display 11b (SA2). For example, the display control unit 12c determines an image, a character, or the like (a map in the example of FIG. 3) to be displayed on the rear display 11b as a display mode of the rear display 11b in the display determined by the navigation application or the HMI application. . Then, image data such as images and characters included in the determined display mode is acquired from the data recording unit 13, and display data for displaying each image data at a predetermined position on the rear display 11b is generated. Based on the display data generated in this way, display control of the rear display 11b is performed.

  Next, the input control part 12b sets the front input area which receives the input corresponding to the screen displayed on the front display 11a to the contact detection surface 10a (SA3). Here, the “screen” is a screen including one or a plurality of operation images that are targets of an input operation via the touch panel 10. Note that the “operation image” includes, for example, images such as various icons and switches to be pressed through the touch panel 10, and maps and photos to be subjected to a flick operation and an enlargement / reduction operation through the touch panel 10. Etc. may also be included. For example, when the navigation application or the HMI application determines what the front display 11a and the rear display 11b display as a whole, these applications determine the screens to be displayed on the front display 11a and the rear display 11b. Information for specifying is input to the display system. Based on the information input in this way and the display data generated by the display control unit 12c at SA1, the input control unit 12b specifies the screen displayed on the front display 11a (in the example of FIG. screen). Then, an area on the contact detection surface 10a corresponding to the identified screen (an area overlapping each icon on the home screen in the example of FIG. 3) is set as a front input area for receiving an input corresponding to the screen. When there are a plurality of operation images, a plurality of front input areas corresponding to each operation image may be set.

  Subsequently, the input control unit 12b sets a rear input area for receiving an input corresponding to the screen displayed on the rear display 11b on the contact detection surface 10a (SA4). For example, the input control unit 12b specifies the screen to be displayed on the rear display 11b based on the information specifying each screen input by the navigation application or the HMI application and the display data generated by the display control unit 12c in SA1. (Map in the example of FIG. 3). And the area | region (for example, area | region which overlaps with a map) on the contact detection surface 10a corresponding to the specified screen is set as a back input area which receives the input corresponding to the said screen. In the present embodiment, a screen (for example, a map) is displayed on the entire rear display 11b, and the entire area of the contact detection surface 10a overlapping the screen is set as the rear input area.

  Next, the input control unit 12b executes an input control process for controlling reception of an input corresponding to a screen displayed on the front display 11a or the rear display 11b (SA5).

(Processing-Input control processing)
Here, the input control process will be described. FIG. 6 is a flowchart of the input control process.

  As shown in FIG. 6, when the input control process is started, the input control unit 12b specifies the type of the screen displayed on the front display 11a and the type of the screen displayed on the rear display 11b (SB1). . For example, the input control unit 12b displays information on the front display 11a and the rear display 11b based on the information specifying each screen input by the navigation application or the HMI application and the display data generated by the display control unit 12c in SA1 and SA2. Specify the type of screen displayed. FIG. 7 is a front view illustrating the display on the front display 11a and the rear display 11b. In the example of FIG. 7, “audio” is specified as the type of the screen displayed on the front display 11a, and “map” is specified as the type of the screen displayed on the rear display 11b.

  Returning to FIG. 6, the input control unit 12 b waits until contact is detected on the contact detection surface 10 a of the touch panel 10 (SB <b> 2, No). When contact is detected on the contact detection surface 10a of the touch panel 10 (SB2, Yes), it is determined whether or not the contact position detected on the contact detection surface 10a is the front input area (SB3). That is, the input control unit 12b determines whether or not the coordinates indicating the detection position on the contact detection surface 10a are included in the front input area set in SA3 of FIG. In the example of FIG. 7, on the contact detection surface 10a, an area that overlaps the audio screen (or an area that overlaps the switch or slider of the audio screen) is set as the front input area, and an area that overlaps the map is set as the rear input area. . Therefore, when the contact position detected on the contact detection surface 10a in SB1 is an area overlapping the audio screen (or an area overlapping the audio screen switch or slider), the input control unit 12b detects the contact position on the contact detection surface 10a. It determines with a contact position being a front input area.

  Returning to FIG. 6, when the contact position detected on the contact detection surface 10a is the front input area (SB3, Yes), that is, the front input in which the coordinates indicating the detection position on the contact detection surface 10a are set in SA3 of FIG. When included in the area, the determination unit 12a determines the type of input detected on the contact detection surface 10a (SB4). For example, the determination unit 12a determines whether the type of input detected on the contact detection surface 10a corresponds to pressing of a switch, tracing, flicking, or multi-touch.

  Next, the input control unit 12b determines that the input type determined by the determination unit 12a is a type that can be accepted as an input corresponding to the screen displayed on the front display 11a, and the screen displayed on the rear display 11b. It is determined whether or not the type is acceptable as an input corresponding to (SB5). That is, the input control unit 12b refers to the input type table 13a and inputs type information corresponding to the type of screen displayed on the front display 11a specified in SB1, and the type of screen displayed on the rear display 11b specified in SB1. And input type information corresponding to. Then, each of the input type information corresponding to the type of the screen displayed on the front display 11a and the input type information corresponding to the type of the screen displayed on the rear display 11b is determined by the determination unit 12a in SB4. When the input type information corresponding to the input type is included, the input type determined by the determination unit 12a in SB4 is a type that can be accepted as an input corresponding to the screen displayed on the front display 11a. In addition, it is determined that the type is acceptable as an input corresponding to the screen displayed on the rear display 11b.

  In the example of FIG. 4, when the type of the screen displayed on the front display 11a specified in SB1 is “audio”, “switch press” and “trace” are acquired as the corresponding input type information. Further, when the type of the screen displayed on the rear display 11b specified in SB1 is “map”, “multi-touch”, “flick”, and “trace” are acquired as the corresponding input type information. In this case, when the input type information corresponding to the input type determined in SB4 is “Trace”, the input type information includes the input type information corresponding to the type of the screen displayed on the front display 11a, and the rear Since it is included in each of the input type information corresponding to the type of screen displayed on the display 11b, the input type determined by the determination unit 12a in SB4 corresponds to the screen displayed on the front display 11a. It is determined that it is a type that can be accepted as an input to be received, and a type that can be accepted as an input corresponding to the screen displayed on the rear display 11b.

  Returning to FIG. 6, as a result of the determination in SB5, the type of input determined by the determination unit 12a in SB4 is a type that can be accepted as an input corresponding to the screen displayed on the front display 11a, and the rear display 11b. If the input is a type that can be accepted as an input corresponding to the screen displayed on the screen (SB5, Yes), the input control unit 12b corresponds to the screen detected on the front display 11a with the contact detected on the contact detection surface 10a. (SB6). As described above, when there is a possibility that both the screen displayed on the front display 11a and the screen displayed on the rear display 11b may be input targets, the contact detected on the contact detection surface 10a is detected as the front display 11a. As a result, the input corresponding to the screen displayed on the front display 11a is given priority, and the screen displayed on the display relatively close to the user is used. Intuitive operation is possible. However, if there is a possibility that both the screen displayed on the front display 11a and the screen displayed on the rear display 11b may be input targets, the input corresponding to the screen displayed on the rear display 11b is accepted. Alternatively, an inquiry screen for inquiring the user as to which display corresponds to the screen displayed on the display may be output.

  In the example of FIGS. 4 and 7, the contact position detected by the contact detection surface 10a in SB2 is an area overlapping the slider of the audio screen, and the type of input determined by the determination unit 12a in SB4 is “Trace”. In this case, the type of the input is a type that can be accepted as an input corresponding to the screen (that is, the audio screen) displayed on the front display 11a, and the input that corresponds to the screen (that is, the map) displayed on the rear display 11b. Therefore, the input control unit 12b accepts the contact detected on the contact detection surface 10a as an input corresponding to the screen displayed on the front display 11a (for example, an input for moving the slider).

  Returning to FIG. 6, after the process of SB6, the input control unit 12b executes a process corresponding to the input received in SB6 (SB7). For example, when an input corresponding to the audio screen (for example, an input for moving the slider) is accepted in the example of FIG. 7, the input control unit 12b executes a process corresponding to the input (for example, a process for changing the volume). Thereafter, the input control unit 12b ends the input control process and returns to the main routine.

  Returning to FIG. 6, as a result of the determination in SB5, the type of input determined by the determination unit 12a in SB4 is not a type that can be accepted as an input corresponding to the screen displayed on the front display 11a, or the rear display If the input type is not a type that can be accepted as an input corresponding to the screen displayed on 11b (SB5, No), the input control unit 12b displays the type of input determined by the determination unit 12a on the front display 11a. It is determined whether or not the type is acceptable as an input corresponding to (SB8). That is, the input control unit 12b refers to the input type table 13a, and acquires input type information corresponding to the type of screen displayed on the front display 11a specified in SB1. If the input type information corresponding to the type of input determined in SB4 is included in the input type information corresponding to the type of screen displayed on the front display 11a, the input determined by the determination unit 12a in SB4 Is determined to be a type that can be accepted as an input corresponding to the screen displayed on the front display 11a.

  As a result of the determination of SB8, the type of input determined by the determination unit 12a in SB4 is a type that can be accepted as an input corresponding to the screen displayed on the front display 11a (SB8, Yes). The input control unit 12b The contact detected on the contact detection surface 10a is received as an input corresponding to the screen displayed on the front display 11a (SB6). In the example of FIGS. 4 and 7, the contact position detected on the contact detection surface 10a in SB2 is an area overlapping the switch on the audio screen, and the type of input determined by the determination unit 12a in SB4 is “switch pressed”. In this case, since the type of the input is a type that can be accepted as an input corresponding to the screen (that is, the audio screen) displayed on the front display 11a, the input control unit 12b is detected on the contact detection surface 10a. The contact is accepted as an input corresponding to the screen displayed on the front display 11a (for example, an input for pressing a switch on the audio screen).

  Returning to FIG. 6, as a result of the determination in SB8, the type of input determined by the determination unit 12a in SB4 is not a type that can be accepted as an input corresponding to the screen displayed on the front display 11a (SB8, No). The input control unit 12b receives the contact detected on the contact detection surface 10a as an input corresponding to the screen displayed on the rear display 11b (SB9). In the example of FIGS. 4 and 7, the contact position detected on the contact detection surface 10a in SB2 is an area overlapping the audio screen, and the input type determined by the determination unit 12a in SB4 is “multi-touch”. The type of the input is not a type that can be accepted as an input corresponding to the screen (that is, the audio screen) displayed on the front display 11a, but is an input that corresponds to the screen (that is, “map”) displayed on the rear display 11b. Since it is a type that can be accepted, the input control unit 12b inputs the touch detected on the touch detection surface 10a corresponding to the screen displayed on the rear display 11b (for example, multi-touch for enlarging or reducing the map). Etc.).

  Returning to FIG. 6, in SB3, when the contact position detected on the contact detection surface 10a is not the front input area (SB3, No), the coordinates indicating the detection position on the contact detection surface 10a are set in SA3 of FIG. If it is not included in the front input area, the contact position detected on the contact detection surface 10a is the rear input area, and the input control unit 12b displays the contact detected on the contact detection surface 10a on the rear display. It is accepted as an input corresponding to the screen displayed in 11b (SB9). In the example of FIGS. 4 and 7, when the contact position detected by the contact detection surface 10a in SB2 is an area that does not overlap with the audio screen, that is, when the contact position is an area that overlaps only the map, the input control unit 12b The contact detected on the contact detection surface 10a is received as an input corresponding to the screen displayed on the rear display 11b (for example, a trace input for moving the map).

  Returning to FIG. 6, after the process of SB9, the input control unit 12b executes a process corresponding to the input received in SB9 (SB7). For example, when an input corresponding to a map is accepted in the example of FIG. 7, the input control unit 12b executes a process corresponding to the map (for example, movement, enlargement, reduction, etc. of the map). Thereafter, the input control unit 12b ends the input control process and returns to the main routine.

  Returning to FIG. 5, after executing the input control process in SA5, the control unit 12 ends the input process.

(effect)
Thus, according to the embodiment, whether or not the type of input is a type that can be accepted as an input corresponding to the screen displayed on the front display screen, and an input corresponding to the screen displayed on the rear display screen And accepting either an input corresponding to the screen displayed on the front display screen or an input corresponding to the screen displayed on the rear display screen based on the determination result. Therefore, even if the user does not specify the display on which the screen to be input is displayed, the input corresponding to the screen displayed on the appropriate display can be automatically received, and the input system including the touch panel 10 The operability in 1 can be improved.

  Also, if the input type is a type that can be accepted as an input corresponding to the front display screen and is a type that can be accepted as an input corresponding to the rear display screen, the input corresponding to the front display screen is accepted. When both the front display screen and the rear display screen have the possibility of being input, it is possible for the user to accept input corresponding to the screen displayed on the display relatively close to the user, which is intuitive for the user. Operations can be performed.

  Further, when the contact position detected on the contact detection surface 10a is outside the front input area, the input corresponding to the rear display screen is accepted, so the user does not have to specify the display on which the screen to be input is displayed. In addition, it is possible to accept an input corresponding to a screen displayed on an appropriate display according to the type of input and the contact position, and the operability in the input system 1 including the touch panel 10 can be further improved.

  Whether the input type is a type that can be accepted as an input corresponding to the front display screen displayed on the front display 11a, and an input corresponding to the rear display screen displayed on the rear display 11b. It is determined whether it is a type, and based on the determination result, either an input corresponding to the front display screen displayed on the front display 11a or an input corresponding to the rear display screen displayed on the rear display 11b is received. Therefore, in the multi-layer display type display system configured by superimposing the front display 11a and the rear display 11b, the operability can be further improved.
