<p><P>PROBLEM TO BE SOLVED: To provide an information processing system capable of automatically calibrating in which place of an image taken by a camera a controlled device is present. <P>SOLUTION: The information processing system 1 comprises the controlled device 2 including at least one of a display area, a means generating a predetermined sound, a marker reflecting electromagnetic wave in an incoming direction, and a means emitting light in a predetermined pattern; and a control device 4. The control device 4 identifies the position of the controlled device 2 based on image information showing the display area displaying a predetermined image. The control device 4 identifies the position of the controlled device 2 from information obtained by catching the sound generated from the controlled device by a microphone array. The control device 4 identifies the position of the controlled device 2 based on the electromagnetic wave reflected by the marker. The control device 4 identifies the position of the controlled device 2 by detecting the light emitted by the controlled device 2. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
