APPARATUS AND METHOD FOR PROVIDING A USER INTERFACE BY A GESTURE, PARTICULARLY FOR EXECUTING A FUNCTION CORRESPONDING TO A SPECIFIC GESTURE OF A USER RECOGNIZED BY A TERMINAL

摘要

PURPOSE: An apparatus and method for providing a user interface by a gesture are provided to recognize a specific gesture through the variation on a coordinate value of a feature point.;CONSTITUTION: A terminal control unit(10) analyzes image data which are acquired. The terminal control unit extracts feature points of first and second gestures. The terminal control unit obtains the coordinate values of the extracted feature points, and senses the variation of the obtained coordinate values. The terminal control unit recognizes the second gesture by using at least two changed coordinate values. The terminal control unit executes the function corresponding to the recognized second gesture.;COPYRIGHT KIPO 2011
