Abstract:
A space sensing device comprises: a user gesture sensing module for sensing a user gesture from an image received from a sensor and outputting information on the sensed gesture; a touch determining module for determining, based on the gesture information, whether the user touches a virtual plane and according to the determining result, outputting coordinate values when the user touches the virtual plane; and a control signal generation module for comparing coordinate information of a graphic user interface, being displayed on the screen of a host, with the coordinate values, and outputting a control signal, corresponding to the coordinate values, to the host according to the comparison result.

Abstract:
PURPOSE: A haptic information processing unit is provided to transmit and receive the haptic information by transmitting and receiving images which do not have changed value in format or data quantity. CONSTITUTION: A haptic information generating unit(1210) generates haptic information. A header generating unit(1220) generates header information. The header information constitutes the encoding target data with the haptic information. An encoding unit(1230) encodes encoding object data by using LSB(Least Significant Bit) of original image pixels' each byte data.
