Abstract

An information processing device, method and computer program storage device that cooperate to handle different user interface situations differently. An exemplary device detects an external object as being in a touch state when and external object is in contact with a detection surface, and an adjacent state when the external object is within a predetermined distance from said detection surface but not in contact with said detection surface. A processor, when operating in a first mode, processes the touch state differently than the adjacent state. Also, the processor when operating in a second mode, processes said adjacent state as if it was the touch state.
