<p>To provide a non-contact operation device having low power consumption, a quick algorithm for recognizing a motion, low manufacturing cost, and a simple motion recognition processing step, the present invention provides the non-contact operation device comprising: one or more light-emitting portions for emitting light; one or more light receiving portions comprising a plurality of light sensors arranged in horizontal and vertical arrays, for receiving light from the light emitting portion as a light source and reflected due to a motion of an object, and converting into an electric signal an optical signal with respect to the motion of the object containing information on the strength and angle of the light that is received; and a micro-control unit (MCU) for receiving an input of the electric signal, calculating space coordinates of the object, determining a gesture motion with respect to the motion of the object by using the space coordinates, and generating a control signal corresponding to the gesture motion.</p> |
