Information processing device

Provided is an information processing device which allows a user to provide, regardless of a position or direction of a touch sensor, an operation input to the touch sensor at an arbitrary position or in an arbitrary direction. The information processing device includes two touch sensors each including a detection surface for detecting a position of an object thereon, the two touch sensors being arranged to be opposed to each other, determines at least one of a reference point and a reference axis based on one or a plurality of positions detected by one touch sensor of the two touch sensors, and evaluates a content detected by another touch sensor of the two touch sensors based on the at least one of the determined reference point and the determined reference axis to determine a content of an operation input of a user.
