FIELD: physics, computer engineering.
SUBSTANCE: invention relates to information processing devices. The device comprises an operation sensor unit through which touch operations are performed using at least operators, a detection unit designed to detect the touch state of each of the operators touching the operator sensor unit, a coordinate system determination unit designed to determine the coordinate system of the operation sensor unit according to the direction of operation of the operators detected by the detection unit, a relative position calculation unit designed to calculate the relative position of each of two or more operators from the touch position of operators detected by the detection unit, and the coordinate system of the operation sensor unit, determined by the coordinate system determination unit, and a command generating unit designed to generate a command for a given operation based on the touch state of each of the operators detected by the detection unit in the relative position of the operators calculated by the relative position calculation unit.
EFFECT: enabling control of a touch screen without visual recognition of the display.
