Abstract

There is provided an information processing apparatus with an interface with high convenience for a user. A reference speed is set according to an amount of movement or a movement time period of a pointer of a stylus or a finger. It is determined based on a movement speed of the pointer and the reference speed that a flick operation with the pointer has occurred.

Claims

1. An information processing apparatus configured to determine a flick operation of a pointer, the information processing apparatus comprising:

a setting unit configured to set a reference pointer speed depending on an amount of movement of the pointer; and

a determination unit configured to determine whether the flick operation of the pointer has occurred based on a movement speed of the pointer and the set pointer reference speed.

2. The information processing apparatus according to claim 1, wherein, when the amount of movement of the pointer is not larger than a predetermined threshold, the setting unit sets a first reference speed and, when the amount of movement is larger than the predetermined threshold, sets a second reference speed larger than the first reference speed.

3. The information processing apparatus according to claim 2, further comprising:

a decision unit configured to decide the predetermined threshold based on a size of an operation region in which operation with the pointer is allowed.

4. The information processing apparatus according to claim 1, wherein, when the movement speed is greater than the reference speed, the determination unit determines that the flick operation with the pointer has occurred and, when the movement speed is not greater than the reference speed, determines that the flick operation with the pointer has not occurred.

5. The information processing apparatus according to claim 1, further comprising an acquisition unit configured to detect a user operation of a pointer.

6. The information processing apparatus according to claim 5, further comprising a specification unit configured to specify an amount of movement of the pointer based on an output from the acquisition unit.

7. The information processing apparatus according to claim 6, wherein the specification unit specifies the amount of movement by a number of notification times of an event notifying movement.

8. An operation method of an information processing apparatus that determines a flick operation of a pointer, the operation method comprising:

setting a reference pointer speed according to an amount of movement of the pointer; and

determining whether the flick operation with the pointer has occurred based on a movement speed of the pointer and the set reference pointer speed.

14. A non-transitory computer-readable storage medium that stores a program causing a computer to execute the operation method according to claim 8.

9. An information processing apparatus configured to determine a flick operation of a pointer, the information processing apparatus comprising:

a setting unit configured to set a reference pointer speed according to a movement time period of the pointer; and

a determination unit configured to determine whether the flick operation of the pointer has occurred based on a movement speed of the pointer and the set reference pointer speed.

10. The information processing apparatus according to claim 9, wherein, when the movement time period does not exceed a predetermined threshold, the setting unit sets a first reference pointer speed and, when the movement time period exceeds the predetermined threshold, sets a second reference pointer speed larger than the first reference pointer speed.

11. The information processing apparatus according to claim 10, further comprising:

a decision unit configured to decide the predetermined threshold based on a size of an operation region in which an operation with the pointer is allowed.

12. The information processing apparatus according to claim 9, wherein, when the movement speed is greater than the reference pointer speed, the determination unit determines that the flick operation with the pointer has occurred and, when the movement speed is not greater than the reference pointer speed, determines that the flick operation with the pointer has not occurred.

13. An operation method of an information processing apparatus that determines a flick operation of a pointer, the operation method comprising:

setting a reference pointer speed according to a movement time period of the pointer; and

determining whether the flick operation of the pointer has occurred based on a movement speed of the pointer and the set reference pointer speed.

15. A non-transitory computer-readable storage medium that stores a program causing a computer to execute the operation method according to claim 13.
