Abstract

An information processing device includes: a display unit having a touch panel on its front surface; a movement amount calculation unit that calculates the movement amount of a touch operation based on a touch point at which the touch operation is performed with respect to the touch panel and a touch release point at which the touch operation is released from the touch panel; an operation determination unit that determines whether the touch operation is a depression operation or a gesture operation depending on the calculated movement amount; and a command recognition unit that recognizes whether a received command is a command corresponding to the depression operation or the gesture operation.

Claims

1. An information processing device comprising:

display means having a touch panel on its front surface;

movement amount calculation means for calculating a movement amount of a touch operation based on a touch point at which the touch operation is performed with respect to the touch panel and a touch release point at which the touch operation is released from the touch panel;

operation determination means for determining whether the touch operation is a depression operation or a gesture operation depending on the calculated movement amount; and

command recognition means for recognizing whether a received command is a command corresponding to the depression operation or the gesture operation.

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

the operation determination means determines that the touch operation is a gesture operation when the movement amount exceeds a predetermined threshold.

3. The information processing device according to claim 2, wherein

the command recognition means recognizes the command associated with a pattern of the gesture operation.

4. The information processing device according to claim 1, wherein

the operation determination means determines that, when the movement amount is not more than a predetermined threshold and a button is displayed at the touch release point at which the touch operation is released, the touch operation is the depression operation with respect to the button.

5. A touch operation detection method comprising:

a touch point detection step in which touch point detection means detects a touch point at which a touch operation is performed with respect to a touch panel provided on the front surface of display means;

a touch release point detection step following the touch point detection step, in which touch release point detection means detects a touch release point at which the touch operation is released from the touch panel;

a movement amount calculation step in which movement amount calculation means calculates a movement amount of the touch operation based on the touch point and the touch release point;

an operation determination step in which operation determination means determines whether the touch operation is a depression operation or a gesture operation depending on the calculated movement amount; and

a command recognition step in which command recognition means recognizes whether a received command is a command corresponding to the depression operation or the gesture operation.

6. The touch operation detection method according to claim 5, wherein

the operation determination step determines that the touch operation is the gesture operation when the movement amount exceeds a predetermined threshold.

7. The touch operation detection method according to claim 6, wherein

the command recognition step recognizes the command associated with a pattern of the gesture operation.

8. The touch operation detection method according to claim 5, wherein

the operation determination step determines that, when the movement amount is not more than a predetermined threshold and a button is displayed at the touch release point at which the touch operation is released, the touch operation is the depression operation with respect to the button.

9. An information processing device comprising:

a display unit having a touch panel on its front surface;

a movement amount calculation unit that calculates a movement amount of a touch operation based on a touch point at which the touch operation is performed with respect to the touch panel and a touch release point at which the touch operation is released from the touch panel;

an operation determination unit that determines whether the touch operation is a depression operation or a gesture operation depending on the calculated movement amount; and

a command recognition unit that recognizes whether a received command is a command corresponding to the depression operation or the gesture operation.
