<P>PROBLEM TO BE SOLVED: To provide a user interface technique for providing feedback to a user based on user's gaze and second user input such as a hand gesture. <P>SOLUTION: A camera-based tracking system tracks a gaze direction of a user to detect which object displayed in a user interface is being viewed. The tracking system also recognizes hand gestures and body gestures to control the action and motion of the object, using, for example, another camera and/or a sensor. As a result, the user interface is updated on the basis of the tracked gaze and gesture data to provide the feedback. <P>COPYRIGHT: (C)2013,JPO&INPIT |
