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.
