<p><P>PROBLEM TO BE SOLVED: To provide an indication movement recognition device capable of an improvement of decision accuracy of an indication position or an indication direction by a user by natural and easy operation. <P>SOLUTION: Video cameras 20A, 20B pick up images of the user from a plurality of directions different from each other. A control part 16 recognizes three-dimensional coordinates of a characteristic point whose position varies according to a change of the indication position or the indication direction when the user makes a movement for indicating a specific position or direction, on the basis of the picked-up images, and decides the indication position or the indication direction by the user on the basis of the three-dimensional coordinates. The control part 16 decides whether the characteristic point is in a stop state or not, on the basis of two-dimensional coordinates in a two-dimensional plane parallel to a large-screen display 14 among the three-dimensional coordinates of the characteristic point. When a movement amount in the two-dimensional plane is a prescribed threshold value or below, the control part 16 decides that it is in the stop state, and changes over a mode to a click mode. When it is not in the stop state, the control part 16 changes over the mode to a pointing mode. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
