Why Do We Need a Body Anyway?

In this talk I will agree with Harry Potter that one should "never trust anything that can think for itself, if you can't see where it keeps its brain". I’ll argue that humans need to locate intelligence, and that this issue poses problems for the disappearing computer. Bodies are the best possible example of located intelligence, of course, and interacting with another person is best done when there is another person to interact with. On this basis of this discussion, I will support the use of embodiment in certain AI domains and demonstrate with a series of implemented systems, including some new work on "shared reality" -a paradigm in which both human and computer share a real physical space within which to make hand gestures, facial displays, body movements, and real physical objects that can be passed back and forth between the real and virtual world.
