Abstract: A “glasses-free” autostereoscopic viewing environment based on a large-diameter, concave vacuum-controlled mirror allows the user to view and interact with a “floating” hologram-like image in real time, without the use of special peripheral devices such as shutter glasses. This technology creates the unique ability to vary focal length over a wide range, yielding superior quality stereo images. Compatibility allows PCs or high-end graphics workstations to drive the system. It also easily interfaces with most haptic devices. A telepresence embodiment allows remote viewing of a live or recorded scene while giving the user the feeling of immersion at the remote site. The remote system consists of a site sensor platform containing stereo cameras and microphones. The platform's patented ability to pan, tilt, and/or roll delivers enhanced control of the captured visual and aural images of the remote site. When captured, any telecommunications system (e.g.
