Abstract

An input method for accepting input information by a touching operation performed on a touch target, includes: acquiring information about the touched region in which the touching operation is performed on the touch target; determining a display mode of an operation target indicator displayed with the touching operation according to the information about the touched region; outputting a display instruction for displaying the operation target indicator in the determined display mode; moving the displayed operation target indicator according to the movement of the touched region; and accepting the input information corresponding to a display position of the operation target indicator when the touching operation is finished.

Claims

1. A non-transitory computer readable medium for storing a computer program which enables a computer to perform an input method for accepting input information by a touching operation on a touch target, the input method comprising:

acquiring information about the touched region in which the touching operation is performed on the touch target;

determining a display mode of an operation target indicator displayed with the touching operation according to the information about the touched region;

outputting a display instruction for displaying the operation target indicator in the determined display mode;

moving the displayed operation target indicator according to the movement of the touched region; and

accepting the input information corresponding to a display position of the operation target indicator when the touching operation is finished.

2. The non-transitory computer readable medium according to claim 1, wherein

the information about the touched region is a area.

3. The non-transitory computer readable medium according to claim 1, wherein

the display mode indicates a size of the operation target indicator.

4. The non-transitory computer readable medium according to claim 1, wherein

the display mode indicates a distance from an edge of the touched region to a tip of the operation target indicator.

5. The non-transitory computer readable medium according to claim 1, wherein

the information about the touched region indicates an area of the touched region and a rectangle corresponding to the touched region,

the determining determines a position on the rectangle as a starting point of the operation target indicator depending on the area of the touched region.

6. The non-transitory computer readable medium according to claim 1, wherein

the determining suppresses a display of the operation target indicator when the area of the touched region is equal to or lower than a threshold,

the accepting accepts input information corresponding to the touched region at a timing when the touching operation finishes.

7. The non-transitory computer readable medium according to claim 6, the input method further comprising

setting the threshold depending on a size of an operation target specified by the operation target indicator.

8. The non-transitory computer readable medium according to claim 1, the input method further comprising

acquiring information about an operation state of an equipment including the touch target, wherein

the determining determines the display mode of the operation target indicator according to the information about the operation state of the equipment and the information about the touched region.

9. The non-transitory computer readable medium according to claim 8, wherein

the information about the operation state is obtained based on a detection signal output from a detection circuit for detecting the operation state of the equipment.

10. The non-transitory computer readable medium according to claim 9, wherein

the detection circuit detects a touching pressure by a touching operation on the touch target.

11. The non-transitory computer readable medium according to claim 9, wherein

the detection circuit detects an inclination of the equipment.

12. The non-transitory computer readable medium according to claim 1, the input method further comprising

classifying the touched region into a plurality of touched region clusters according to the information about the touched region;

wherein

one touched region cluster is selected depending on each area of the plurality of touched region clusters,

the determining determines the display mode of the operation target indicator according to the information about the selected touched region cluster.

13. The non-transitory computer readable medium according to claim 1, the input method further comprising:

detecting a finishing position of the touching operation on the touch target;

designating information for determination of the display mode of the operation target indicator based on the information about the touched region, the determined display mode, and the detected finishing position, wherein

the determining determines the display mode of the operation target indicator according to the designated information and the information about the touched region.

14. An input device which accepts input information by a touching operation performed on a touch target, comprising:

a display unit;

a touch sensor;

a storage unit;

a touched region acquisition unit to acquire information about the touched region in which the touching operation is performed on the touch target using the touch sensor;

a determination unit to determine a display mode of an operation target indicator displayed with the touching operation by referring to information stored in the storage unit according to the information about the touched region acquired by the touched region acquisition unit;

an output unit to output a display instruction for displaying the operation target indicator on the display unit in the display mode determined by the determination unit;

a designation unit to designate an operation target based on a display position of the operation target indicator when the touching operation is finished;

a notification unit to notify the designated operation target of the input information by the touching operation;

a movement unit to move the displayed operation target indicator according to the movement of the touched region; and

an acceptance unit to accept the input information corresponding to the display position of the operation target indicator when the touching operation is finished.

15. The input device according to claim 14, further comprising

a touch detection unit to detect a portion on which the touching operation is performed on the touch target, wherein

the touched region acquisition unit acquires the information about the touched region based on the portion detected by the touch detection device.

16. An input method for accepting input information by a touching operation performed on a touch target, comprising:

acquiring information about the touched region in which the touching operation is performed on the touch target;

determining a display mode of an operation target indicator displayed with the touching operation according to the information about the touched region;

outputting a display instruction for displaying the operation target indicator in the determined display mode;

moving the displayed operation target indicator according to the movement of the touched region; and

accepting the input information corresponding to a display position of the operation target indicator when the touching operation is finished.
