Information processing device and touch operation detection method

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.

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.
