PPT Eyes

Lightweight Stereo Glasses Motion Tracker

PPTEyes is a small, lightweight, wireless motion tracker you can screw onto any commercially available pair of 3D glasses. When used in conjunction with WorldViz PPT motion capture systems, users are able to navigate CAVE, Powerwall, and other projection based display systems without the bulk or clutter of transmitters, clips or cables.

PPTeyes integration with active and passive stereo glasses

Top and front mounted on "Simple blue", "NuVision", NVIDIA", and "ChrystalEyes".

Quality

PPTEyes is a pure optical solution based on two LEDs mounted in line with the user’s pupils. With this simple yet elegant solution, the user’s stereoscopic perspective is captured providing a complete tracking solution to standard 3D visualization engines, including the WorldViz Vizard VR toolkit. An ideal solution in metallic environments where magnetic or inertial systems tend to fail.

Wireless

With a battery endurance of more than 24 hours, and a range of 15 meters, users appreciate the freedom and comfort of a true wireless solution.

Versatile

PPTEyes can be factory of self-mounted onto all commercially available 3D glasses including passive and active models.

Standards

Compatible with TrackD, VRPN, and WorldViz native PPT protocol, this device is ready to connect to your own application no matter what platform you develop on.
