Provided is an information processing device, which is configured to inhibit an unintended operation of a user from being erroneously detected when a flick operation is performed on a curved touch panel. An operation content including a direction of a flick performed with a finger on a curved front surface of a touch panel is detected, and a curvature ratio of the front surface corresponding to the detected direction is acquired. Further, a flick threshold value using a curvature ratio as a parameter is determined, and characteristics of the detected operation content are quantified as a flick score. Then, through comparison between the flick threshold value and the flick score, it is judged whether or not a touch operation is the flick operation.
