Information processing device, method for controlling an information processing device, and program

摘要

An information processing device includes: a display unit; a touch panel that is arranged overlapping the display unit, that detects contact by or proximity with an indication element, and that outputs detection results; and a control unit that displays all or a portion of an operation image on the display unit and, when a portion of the operation image is being displayed on the display unit and a drag operation is carried out that causes sliding of the contact point at which the indication element and touch panel are in proximity or contact, identifies the direction of movement and the amount of movement of the contact point that accompany the drag operation, and scrolls the display of the display unit by an amount that corresponds to the amount of movement that was identified and in the direction opposite to the direction of movement that was identified.

1. An information processing device comprising:
a display unit; a touch panel that is arranged overlapping said display unit, that detects proximity of or contact by an indication means, and outputs detection results; and a control unit that causes display of all or a portion of an operation image on said display unit and that, when a portion of said operation image is being displayed on said display unit and when a drag operation is carried out, in which a contact point at which said indication means and said touch panel are in proximity or contact, is caused to slide, identifies a direction of movement and an amount of movement of said contact point that accompany said drag operation and scrolls a display of said display unit by an amount that is equal to said amount of movement that was identified and in a direction opposite to said direction of movement that was identified, wherein when the contact point at a time of completing said drag operation is on an operation button that is part of a virtual display or keyboard included in said operation image and that indicates a content of an operation, upon removal of the indication means from the touch panel said control unit carries out a process that corresponds to the content of the operation that was indicated by the operation button, and when the contact point of indication means with touch panel has reached an outer periphery of effective detection range in accompaniment with the drag operation, the display of the display unit is scrolled by a size vector in which the direction is equal to that of a display scroll vector in addition to the display scroll vector having a vector size that is equal to that of a movement vector of the contact point but in which the direction is opposite.
