Description

  The present disclosure relates to an information input device, and more particularly, to an information input device that receives an input of an instruction based on an operation on an input surface.

  As represented by devices including a touch panel such as a portable information terminal or a smartphone, an information input device including an input surface that receives an operation for an instruction from a user has been put into practical use. In such information input devices, miniaturization has progressed, and in this way, in many cases, a user operates such a device with the device in his / her hand. From this, it is assumed that the user's finger continues to be positioned on the input surface. Thus, if the above device cannot recognize that the user's finger is positioned on the input surface for supporting the device rather than for inputting the instruction, the device does not support Information processing according to an instruction input by a finger positioned on the input surface is executed without intention to input.

  Conventionally, in such an apparatus, when a user's finger continues to be positioned on the input surface as described above, a technique for invalidating input at a portion where the finger is positioned has been proposed. For example, Japanese Patent Application Laid-Open No. 2012-14648 (Patent Document 1) sets the input invalid area in a part of the touch panel in claim 1 and the like on the display screen so as to avoid the set invalid input area. Rearrange the displayed objects.

JP 2012-14648 A

  Information input devices such as smartphones and portable information terminals in recent years have come to accept input of many types of information as the devices become more sophisticated. For this reason, the number of objects displayed on the screen of the device is increasing. However, the rearrangement of the object of the information input device described in Patent Document 1 simply moves the rearranged object to a position where no other object is displayed, as described in FIG. Is. For this reason, when the position of the object is simply changed as described in Patent Document 1, the arrangement of the objects on the screen of the information input device is disturbed, and the convenience of the device is reduced. In addition, when many objects are displayed on the screen, if some of the objects are moved by rearrangement, the object to be moved must be displayed over other objects. Is assumed.

  Depending on the above, according to the technique described in Patent Document 1, it is assumed that the convenience of the apparatus is reduced. For this reason, in the information input device, there has been a demand for a technique corresponding to the user's finger being continuously positioned on the input surface without causing a decrease in convenience.

  The present disclosure has been devised in view of such circumstances, and its purpose is to appropriately change the correspondence between the instructed position and the process to be executed according to the mode of operation on the input surface of the information input device.

When an input in a special instruction mode is detected, the display control means displays the change target area, which is at least a part of the input surface including a portion in contact with the extension area, in the special instruction mode. Before the input is detected, the contents displayed in the change target area and the extended area are updated so as to be reduced and displayed. The relationship between the position indicated on the input surface and the information processing to be executed is changed in accordance with the change of the display mode on the input surface.

  Preferably, the reduction ratio is a ratio of the size of the change target area to the combined size of the extension area and the change target area.

  Preferably, the display control means is configured to display an object on the input surface. The information processing means is configured to execute information processing corresponding to the object when the position where the object is displayed is instructed.

And the relationship between the position instruct | indicated on an input surface and the information processing performed changes with the change of the display mode in an input surface.

  As a result, when an input in a special instruction mode is detected, the content displayed in the extended area before the detection is not simply changed in its display position, but is reduced in the input plane. Is displayed. Therefore, even if the display mode on the input surface is changed due to the detection, the arrangement of the objects on the input surface is hardly disturbed. For this reason, it can avoid that a user's convenience falls as much as possible.

  In the information input device 1, the mode of inputting information (instruction) to the CPU 30 is not limited to instructing an object displayed on the display device 342. That is, the display of the object on the display device 342 is not essential for the input of information to the CPU 30. The display device 342 only needs to display at least a pattern or the like that provides guidance on the position indicated by the touch sensor 341 and the content of information processing executed in response to the position indicated. When a specific coordinate of the touch sensor 341 is designated, information indicating that the coordinate is designated is input to the CPU 30. In addition to the instructed position, the CPU 30 can also receive information indicating the type of instruction (tap, double tap, flip, etc.) on the touch panel 34.

  FIG. 3 shows a touch processing unit 11, an information processing unit 12, a graphic memory 13, and a display driver 14 as functions of the CPU 30. The CPU 30 realizes these functions by executing a given program. The information input device 1 may be provided with a dedicated circuit or device for realizing at least some of these functions.

  The touch processing unit 11 detects a position where an instruction is given by the touch sensor 341 and a mode where the instruction is given. When the touch sensor 341 is, for example, a capacitive touch sensor, the designated position is identified based on the amount of change in the capacitance of the touch sensor 341, and the identified position is output to the information processing unit 12. To do. The touch processing unit 11 also detects an instruction mode (a time during which the instruction is continued, a pattern in which the instruction position changes, etc.) in the touch sensor 341, and a type of instruction (tap, double tap, Flip, etc.) are specified, and the specified type is output to the information processing unit 12.

  In the information input device 1, the input of instructions to the touch sensor 341 is not limited to that in contact with the touch sensor 341.

Information processing includes control of a display mode in the display device 342. As a result of the information processing, the information processing unit 12 generates image data to be displayed on the display device 342 and stores the image data in the graphic memory 13. The display driver 14 displays the image data stored in the graphic memory 13 on the display device 342.

[Functional configuration of information input device]
The functional configuration of the information input device 1 will be described with reference to FIG. FIG. 4 shows a more detailed configuration of the information processing unit 12 of FIG.

  As illustrated in FIG. 4, the information processing unit 12 includes a display area conversion unit 121, a system processing unit 122, and an image processing unit 123. The display area conversion unit 121 executes processing for changing the display target area and redisplaying the contents displayed in the specific area of the display device 342.

  The image processing unit 123 generates image data to be displayed on the display device 342 in accordance with the display mode determined by the display area conversion unit 121.

  According to the functional configuration shown in FIG. 4, in the information input device 1, when the user inputs an instruction to the touch panel 34 (touch sensor 341) with a finger or the like, the touch processing unit 11 causes the position and type of the instruction to be displayed. Is input to the display area conversion unit 121. Information about the position and type of the instruction is also input to the system processing unit 122. The system processing unit 122 determines the content to be displayed on the display device 342 based on the instruction and type.

  Based on the position and type of the instruction input to the touch panel 34, the display area conversion unit 121 specifies an area for displaying the content instructed to be displayed from the system processing unit 122 on the display device 342. Then, the display area conversion unit 121 specifies how to arrange the content instructed to be displayed by the system processing unit 122 in the specified area. Then, the display area conversion unit 121 notifies the image processing unit 123 of the specified arrangement. In response to this, the image processing unit 123 generates image data corresponding to the specified arrangement, and transmits the generated image data to the graphic memory 13. When the image data is transmitted to the graphic memory 13, the display driver 14 displays the image data on the display device 342 as described with reference to FIG.

[Overview of processing for exceptional operations]
In order to more specifically describe an example of the function of the information input apparatus 1 described with reference to FIGS. 3 and 4, processing for exceptional operations in the information input apparatus 1 will be described with reference to FIGS. 5 to 7. The outline of will be described.

  In this specification, an exceptional operation is an operation performed in accordance with a special instruction mode. The exceptional operation includes, for example, an operation in which an instruction is input to the touch panel 34 (touch sensor 341) without the user's intention to operate the information input device 1. More specifically, when the user operates the information input device 1 while holding the information input device 1, the finger supporting the information input device 1 touches the touch panel 34 (touch sensor 341). When the CPU 30 inputs an instruction to the touch panel 34 (touch sensor 341), it is an example of an exceptional operation that the user positions the finger supporting the information input device 1 on the touch panel 34 (touch sensor 341). is there.

  In the information input device 1, the occurrence of an exceptional operation is detected based on the input mode of instructions to the touch panel 34. When an exceptional operation is detected, the information input device 1 changes the display mode on the touch panel 34 (display device 342). More specifically, when an exceptional operation is detected, the content displayed on the touch panel 34 before the detection is reduced by at least a part of the content, and thus the region that is the target of the exceptional operation It will be displayed in the area excluding.

  FIG. 5 shows an example of a screen that displays information in a normal manner on the touch panel 34. As shown in FIG. 5, eight icons 51 to 58 are displayed on the touch panel 34. Eight icons are arranged in a matrix of 2 rows and 4 columns. Each of the icons 51 to 58 has a substantially square shape. Each of the icons 51 to 58 corresponds to the content of information processing in the application being executed in the information input device 1.

  Assume that the user's finger F is continuously located on the touch panel 34 as shown in FIG. 6 when information as shown in FIG. 5 is displayed on the touch panel 34. In the case shown in FIG. 6, a part of the finger F is located on the icon 51. However, the user places the finger F at the position shown in FIG. 6 in order to indicate the information input apparatus 1 instead of indicating the icon 51. In the information input device 1, for example, when the finger F continues to indicate the same position on the touch panel 34 for a predetermined time or longer, the instruction is determined to be an instruction by exceptional operation.

  In such a case, the information input apparatus 1 excludes the area including the position indicated by the finger F from the information display target shown in FIG. 5 on the touch panel 34, as shown in FIG. The information is displayed in the remaining area. When displayed in the remaining area, at least a part of the information is reduced and displayed so as to fit in the remaining area. More specifically, the icon 51X located in the vicinity of the finger F is an icon corresponding to the icon 51 in FIG. 5, and a part of the icon 51 is reduced and deformed.

  The same instruction (information processing) as that assigned to the icon 51 is assigned to the icon 51X. Until an exceptional operation occurs, the CPU 30 displays an icon 51 on the touch panel 34. When an instruction is input within a range corresponding to the icon 51, the CPU 30 executes information processing corresponding to the icon 51. After the exceptional operation occurs, the CPU 30 displays the icon 51X instead of the icon 51 on the touch panel 34. When an instruction is input within a range corresponding to the icon 51X, the CPU 30 executes information processing corresponding to the icon 51X (information processing corresponding to the icon 51). That is, when the icon 51 is replaced with the icon 51X due to the occurrence of an exceptional operation, the area on the touch panel 34 for receiving the input of the information processing instruction corresponding to the icon 51 is displayed from the icon 51 display area to the icon 51X. Replaced with an area. Thereby, in the information input device 1, the relationship between the indicated position on the input surface and the information processing to be executed is changed in accordance with the change of the display mode on the input surface due to the occurrence of an exceptional operation.

[Contents of processing for exceptional operations]
With reference to FIGS. 8-10, the content of the process performed with respect to generation | occurrence | production of exceptional operation in the information input device 1 is demonstrated. FIG. 8 is a flowchart of the process. This process may be executed constantly or only in the background of a specific application. 9 and 10 are diagrams for explaining a display mode of the touch panel 34 in the processing.

  Referring to FIG. 8, in step S <b> 10, CPU 30 determines whether or not an exceptional operation has occurred on touch panel 34. For example, the CPU 30 determines that an exceptional operation has occurred when information indicating that an instruction has been continuously input to the same position on the touch panel 34 is input from the touch processing unit 11. CPU 30 continues the process of step S10 until it is determined that an exceptional operation has occurred. When CPU 30 determines that an exceptional operation has occurred, control proceeds to step S20.

  In step S20, the CPU 30 1) specifies an area that is an object of exceptional operation, 2) specifies an extension area based on the specified area, and 3) determines a change target area based on the extension area. 4) The display mode in the change target area is determined.

  The region that is the target of the exceptional operation is, for example, a region where an instruction is continuously input. More specifically, it is a part of the touch panel 34 where the finger F continues to be positioned as shown in FIG.

  The extended region is a region that is considered difficult to input a normal instruction including a target region for exceptional operations. The extended region is, for example, a region obtained by combining the target region for exceptional operation and the region within a given distance from the outer edge of the target region.

  The change target area is an area in contact with the expansion area among the entire area that displays the touch panel 34 and receives an instruction input (hereinafter also referred to as the entire area). The change target area may be all areas other than the extension area in the entire area, or may be an area in contact with the extension area and a part of the area other than the extension area.

  The display mode in the change target area determined in step S20 includes, for example, reducing and displaying the contents displayed in the change target area and the extension area before the occurrence of the exceptional operation in the change target area. It is done. The display mode determination method will be described more specifically with reference to FIGS. 9 and 10.

  FIG. 9 shows an example of a display mode before an exceptional operation occurs. On the touch panel 34 of FIG. 9, eight icons 51 to 58 are displayed as in FIG. FIG. 9 shows an x-axis and a y-axis that are defined for specifying coordinates on the touch panel 34, and three points P01, P02, and P03 that are referred to in order to explain a display mode determination method. It is shown. The coordinates (x, y) of the points P01, P02, and P03 in the xy plane are P01 (0, 400), P02 (50, 400), and P03 (100, 400), respectively.

  FIG. 10 is a diagram illustrating an example of a display mode changed due to the occurrence of an exceptional operation. In FIG. 10, the area AR1 is shown in the vicinity of the finger F, and AR2 is shown outside the area AR1.

  The area AR1 is an example of the “extended area” described above. The CPU 30 (display area conversion unit 121) specifies the area AR1 as a range located at a given distance from the outer edge of the area where the instruction is input by the finger F of the touch panel 34. The area AR1 includes an area where the finger F exists.

  The area AR2 is an example of the “change target area” described above. The CPU 30 (display area conversion unit 121) specifies the area AR2, for example, by applying the coordinates of the outer edge of the area AR1 to a given function. In the example shown in FIG. 10, a portion of the outer edge portion of the region AR2 that does not contact the outer edge portion of the region AR1 has a size in the x-axis direction of the region AR1 in the x-axis direction from the outer edge portion of the region AR1, for example. Located at a distance away. More specifically, when the x coordinate of the outer edge portion of the area AR1 is expressed by the function f1 of the y coordinate as shown in the following expression (1), the x coordinate of the outer edge portion of the area AR2 is the same function. Using f1, it is expressed in the y coordinate as shown in the following equation (2).

x = f1 (y) (1)
x = 2f1 (y) (2)
Then, in step S20, the CPU 30 (display area conversion unit 121) displays the contents displayed in the areas AR1 and AR2 in the area AR2 before the occurrence of the exceptional operation, that is, the areas AR1 and AR2 in FIG. The display mode of the touch panel 34 is changed so that the content displayed in the area corresponding to is reduced and displayed. More specifically, in the present embodiment, the CPU 30 (display area conversion unit 121) displays the contents displayed in the area AR1 and the area AR2 before the occurrence of the exceptional operation in the area AR2. The image is reduced and displayed at a double reduction ratio.

  As a result of such a change in display mode, the contents instructed to be displayed at points P01, P02, and P03 by the system processing unit 122 are respectively P11, P12, and P13, as shown in FIG. Will be displayed at each point. These three physical positions on the touch panel 34 are P11 (50, 400), P12 (75, 400), and P13 (100, 400).

  Returning to FIG. 8, after changing the display mode in step S <b> 20, the CPU 30 determines in step S <b> 30 whether or not the exceptional operation on the touch panel 34 has ended. For example, the CPU 30 determines that the exceptional operation has been completed when there is no longer a continuous instruction input detected in step S10. CPU30 continues the process of step S20 and step S30 until it judges that exceptional operation was complete | finished. Then, when determining that the exceptional operation has ended, the CPU 30 advances the control to step S40.

  In step S40, CPU30 resets the change of the display mode in step S20. Thereby, the display mode on the touch panel 34 is returned from the one shown in FIG. 10 to the one shown in FIG. Then, the CPU 30 returns the control to step S10.

[Modification]
In the present embodiment, an operation performed in accordance with a special instruction mode is detected as an exceptional operation. When an instruction is input from the user to the touch panel 34 in an unintentional manner by an exceptional operation, the information input apparatus 1 receives the instruction that has been displayed on the touch panel 34 until then. Display in parts other than parts. Information displayed in the part where the instruction is input is reduced and displayed in the remaining part of the touch panel 34. The remaining part (change target area) here may be all of the part other than the extension area, or may be a part of the part other than the extension area. Further, the extension area may be the target area itself of the exceptional operation.

  In addition, the detection mode of occurrence of exceptional operations is not limited to whether or not the instruction to the same position on the touch panel 34 has continued for a certain time or more, and whether or not the touch panel 34 has been touched with a pressure higher than a given pressure is specified. (For example, a part of the touch panel 34 is instructed while operating the operation button 33).

  In the present embodiment, the information input device 1 does not display information in the extended area as shown in FIG. 10 when an exceptional operation occurs. Note that the information input apparatus 1 may display a given background image in the extended area for the purpose of notifying or decorating that the area is handled as the extended area.

  Further, the information input apparatus 1 may assign special information processing to the extended area. For example, the information input device 1 may display a special image when an instruction is input to the extended area in a special manner such as a double tap. From the viewpoint of such a modification, the exceptional operation is not limited to an operation that is not intended by the user. The user may intentionally perform an exceptional operation in order to display the special image.

  Further, the extension area may be used in combination with an instruction input for an area other than the extension area. For example, an instruction input mode for an area other than the extension area can be corrected based on an instruction input for the extension area. More specifically, for example, the CPU 30 may correct the content of an instruction input based on an operation on an area other than the expansion area based on the instruction input to the expansion area.

  Moreover, the instruction | indication with respect to an expansion area | region may have an independent function. For example, the CPU 30 may end the running application when an instruction is input in a special manner (for example, a double tap) to the extended area. Thereby, during execution of the application, for example, the user continuously instructs (or touches) a part of the touch panel 34, and terminates the application being executed by double-tapping the extension area generated thereby. Can be input.

  As shown in FIG. 10, in this embodiment, an exceptional operation is detected at the end of the touch panel 34. However, other than the end of the touch panel 34, exceptional operations can occur and be detected.

  It should be thought that embodiment disclosed this time and its modification are illustrations in all the points, and are not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims. It is intended that the techniques disclosed in the embodiments and the modifications thereof can be implemented alone or in combination as much as possible.
