Japan Today has published an article on SIG, a humanoid robot being developed by The ERATO Kitano Symbiotic Systems Project. SIG has stereo hearing and vision. The robot has voice and face recognition systems. Real-time auditory and visual multiple-object tracking is used to point the head at the speaker. Videos of the system in action are available on the SIG website. The robot was designed to recognize and locate voices in the environments typical of a receptionist or museum guide.
