Abstract

According to the present invention, a detection unit (110) detects a touch on an information processing device (100), and a control unit (120) performs control based on the touch detected by the detection unit (110), and ignores the result of a detection by the detection unit (110) in proportion to the time during which the location of the touch detected by the detection unit (110) does not change.

Claims

1. An information processing apparatus comprising:

a detection section that detects a touch; and

a control section that performs control based on the touch detected by said detection section and ignores a result detected by said detection section according to a period of time during which a touch position detected by said detection section has not moved.

2. The information processing apparatus according to claim 1, wherein

said control section ignores the result detected by said detection section for a time corresponding to the period of time during which the touch position detected by said detection section has not moved.

3. The information processing apparatus according to claim 1, wherein

said control section sets an ignoring time such that the longer the period of time during which the touch position detected by said detection section has not moved, the longer is the ignoring time during which the result detected by said detection section will be ignored.

4. The information processing apparatus according to claim 3, wherein

said control section calculates and sets the ignoring time using an expression where a second order differential value of an expression for calculating the ignoring time based on the period of time during which the touch position detected by said detection section has not moved is always a positive value.

5. The information processing apparatus according claim 1, comprising

a display section, wherein

said detection section detects a touch on a display surface of said display section.

8. The information processing apparatus according to claim 2, wherein

said control section sets an ignoring time such that the longer the period of time during which the touch position detected by said detection section has not moved, the longer is the ignoring time during which the result detected by said detection section will be ignored.

9. The information processing apparatus according claim 2, comprising

a display section, wherein

said detection section detects a touch on a display surface of said display section.

10. The information processing apparatus according claim 3, comprising

a display section, wherein

said detection section detects a touch on a display surface of said display section.

11. The information processing apparatus according claim 4, comprising

a display section, wherein

said detection section detects a touch on a display surface of said display section.

12. The information processing apparatus according claim 8, comprising

a display section, wherein

said detection section detects a touch on a display surface of said display section.

6. An information processing method of performing:

a process of detecting a touch;

a process of performing control based on the detected touch; and

a process of ignoring the detected result according to a period of time during which the detected touch position has not moved.

7. A non-transitory computer-readable medium storing a program for causing a computer to execute:

a procedure for detecting a touch;

a procedure for performing control based on the detected touch; and

a procedure for ignoring the detected result according to a period of time during which the detected touch position has not moved.
