Tokyo University graduate student Hideki Nakayama looks at an artificial begonia flower while wearing "AI Goggles", which is equipped with a web camera and a head-mounted display, during a demonstration at his university's laboratory of the Information Science and Technology in Tokyo March 31, 2008. The system, jointly developed by Nakayama, assistant professor Tatsuya Harada and professor Yasuo Kuniyoshi, captures images from the user's point of view with the web camera, annotates them and outputs the result to the head-mounted display and a computer.
