Information processing device, method for controlling information processing device, program, and information recording medium

The present invention enables the changing of a region in which information that is to be displayed is not displayed within a display in accordance with the detection position of a touch sensor disposed opposite a touch sensor disposed overlapping the display. An information processing device (1) is provided with: a touch panel (12) configured containing a display and a front surface touch sensor that is disposed overlapping the display and that detects the position of an object on a detection surface; a back surface touch sensor (18) that is disposed opposite the front surface touch sensor and that detects the position of an object on a detection surface; and a control unit. On the basis of at least one detection position from the back surface touch sensor (18), the control unit identifies one of two regions respectively disposed at the left and right constituting a portion of the display as a forbidden region, and displays information that is to be displayed at the region other than the forbidden region in the display.
