Early research in artificial intelligence (AI) emphasized mechanisms of symbol processing with the goal of isolating an essential core of intelligent behavior. Although huge progress was made in understanding automated reasoning, an unsolved problem has been that of specifying the grounding of the symbols. More recently, it has been appreciated that the human body, largely neglected in symbolic AI, may be the essential source of this grounding. Graphics models that simulate extensive human capabilities can be used as platforms from which to develop synthetic models of visuomotor behavior. Research programs that focus on embodiment have been facilitated by the development of virtual reality (VR) graphics environments. These VR environments can now run in real time on standard computing platforms. The value of VR environments is that they allow for the creation of virtual agents that implement complete visuomotor control loops. Visual input can be captured from the rendered virtual scene, and motor commands can be used to direct the graphical representation of the virtual agent's body.
