If you think your Second Life avatar is kewl, think again. Edd Hifeng is not just a typical virtual world figure. He is actually an AI created by researchers at Rensselaer Polytechnic Institute. He can converse and reason to a limited extent. While he can answer limited questions, he only understands English that has been translated into mathematical logic. Director Selmer Bringsjord says Edd could be a hint of things to come and hopes that it will lead to more sophisticated holograms that can interact with people in 3D settings such as subway stops.
