1. A system, comprising: a communication system; first and second display and capture systems each locally capturing images and sound and transmitting the locally captured images and sound over the communication system, and receiving remotely captured images and sound and displaying/playing the remotely captured images and sound to a viewer and where each display and capture system comprises: a desk top robotic movable arm having three degrees of freedom; a movable display connected to an end of the movable arm, having three degrees of freedom and movable independently of the arm and displaying the remotely captured images and a common stereo image; a stereo/autostereo image projection system associated with the display for projecting a stereo image of the captured images to a viewer of the display and having a preferred viewing angle; near field speakers producing stereo sound from the remotely captured sound; video sensors including cameras mounted on the display and for capturing a stereo image of a head of a viewer viewing the display; light sources in association with the video sensors; sound sensors including microphones mounted on the display for capturing stereo sound from the head of the viewer viewing the display; a touch sensitive handle attached to the display/arm allowing a user to move the display and providing direction and movement amount outputs; and a computer system, communicating with the communication system; processing the locally captured stereo image using Kalman filter to determine a head position and head orientation of the head of the viewer; processing the locally captured stereo image to determine an eye position of the viewer; adjusting a position of the movable arm and the movable display, when the handle is not being touched, to maintain the head of the viewer within the viewing angle and responsive to an environmental constraint map indicating objects within the movement range of the display and arm; adjusting a position of the movable arm and the movable display responsive to the direction and movement amount outputs when the handle is being touched; transmitting the locally captured images and sound, the head position and orientation, the eye position and the display/arm position through the communication system; processing remotely captured images for display through the stereo image projection system by the movable display; processing remotely captured sound and providing the stereo sound to the speakers; processing the remotely captured images to determine a viewing frustum of a remote viewer responsive to the remotely determined head position and orientation, eye position and the remote display/arm position and displaying the viewing frustum on the display associated with a view of the remote viewer showing an orientation of the remote viewer; maintaining a 3D object in a common world coordinate system being viewed by the first and second systems; determining a cut plane view of the 3D object on the display responsive to a position of the display with respect to the common world coordinate system, displaying a view of the 3D object on the display; displaying the frustum of the remote viewer relative to the 3D object on the display; and displaying a representation of the cut plane view of the remote viewer on the display.
