FIELD: physics.
SUBSTANCE: device has a display unit configured to display images on two adjacent screens, respectively, an input unit configured to acquire position coordinates on the display unit, a gesture recognition unit configured to recognise and execute stored processing commands corresponding to the form of change of associated coordinates through chronologic association of position coordinates. The gesture recognition unit switches to a no reception status where recognition and execution of processing commands is prohibited, when coordinates acquired by the input unit do not include a given fixed coordinate, and a receiving status where recognition of processing commands is permitted, when coordinates acquired by the input unit include a fixed a coordinate.
EFFECT: high accuracy of input operations when holding the device.
