Abstract
A gesture input apparatus comprises: a plurality of multiaxis angular velocity sensors or multiaxis acceleration sensors respectively for detecting multiaxis angular velocities or multiaxis accelerations; a difference sampling circuit for outputting the difference between one of outputs from the sensors, as a reference value, and outputs from the other sensors; a gesture dictionary for pre-storing sample values of feature relative value outputs; an arithmetic operation controller for recognizing gesture, by comparing an output value from the difference sampling circuit with a value within the gesture dictionary, based on output indicative of change in elapse of time, from said difference sampling circuit, as one set of data; and a distance sensor for detecting the relative distance between a fixed member and a movable member by using sound waves or light.
