Information processing device, information processing method, and information processing program

摘要

An information processing device including an operation unit in which an operation input is possible by a touch operation on an operating surface; and a control unit that executes processing corresponding to an operation input performed via the operation unit, wherein the control unit causes, if an area of a portion that is in contact with the operating surface accompanying a touch operation is obtained and a touch operation in which the area is equal to or greater than a predetermined value is performed, restoration information for later restoring the display contents of a screen that are currently being displayed on a display unit to be stored in a memory unit, and display contents of a screen are restored, according to an operation input performed via the operation unit, based on the restoration information recorded in the memory unit.

主权项

1. An information processing device comprising:
an operation unit that receives an operation input, the operation input comprising a touch operation on an operating surface; and a control unit that executes processing corresponding to the operation input when an area of contact on the operating surface during the touch operation is equal to or greater than a predetermined area, the processing comprising:
storing restoration information related to a display content that is being displayed at a point in time on a display screen of a display unit, the restoration information including a scrolling amount of a range of the display content that is being displayed at the point in time; andrestoring the display content based on the stored restoration information, wherein if the control unit determines that a length of a drag of the touch operation is equal to or greater than a predetermined length and a direction of the drag of the touch operation is performed in a predetermined direction the control unit stores the restoration information in a memory unit, wherein the restoration information includes information for restoring the display content at the point in time to a state in which a second operation input is possible, wherein the operation unit receives the second operation input, the second operation input comprising a second touch operation on the operating surface, and wherein the second operation input is a same type of operation as the first operation input.
