Information processing device, control method for the same and program

摘要

Information processing device includes display unit that displays operation object; tactile contact detection unit that detects a plurality of push-down points; and control unit that performs first operation assessment for detecting whether or not outer peripheral distance of first area formed by connecting adjacent push-down points among a plurality of push-down points detected by tactile contact detection unit decreases over time to predetermined value or less, and that performs second operation assessment for detecting whether or not the outer peripheral distance of second area formed by connecting adjacent push-down points among a plurality of push-down points detected by tactile contact detection unit increases over time to predetermined value or more. Control unit puts operation object in selected state when there is overlapping part between operation object and first area after first operation assessment, and performs first operation corresponding to place where second operation assessment has been performed on operation object.

主权项

1. An information processing device, comprising:
a display unit that displays a device's operation object; a tactile contact detection unit that detects a plurality of push-down points; and a control unit that:
puts said device's operation object in a selected state when there is an overlapping part between said device's operation object and an area formed by connecting adjacent push-down points among said plurality of push-down points detected by said tactile contact detection unit when a user's pinch operation is detected;performs a user's operation assessment for detecting a user's release operation;determines whether a number of push-down points when said user's release operation is detected and a number of push-down points when said device's operation object is put in the selected state are equal;performs a first device's operation in a case where said number of push-down points when said user's release operation is detected and said number of push-down points when said device's operation object is put in the selected state are equal; andperforms a second device's operation in a case where said number of push-down points when said user's release operation is detected and said number of push-down points when said device's operation object is put in the selected state are different.
