Virtual Reality Scene Generator (VRSG™) With Tracker Support

MetaVR's VRSG supports 3 or 6 degree-of-freedom position tracking technology from InterSense. This capability totally immerses users in a simulated world with either a hand held visual device or a head-mounted display (HMD). VRSG's tracker support is integrated directly with the display mechanism such that latency is minimized during rapid movements by the user. 

The adjacent image shows a single-channel VRSG integrated with a Mini Eye-safe Laser Infrared Observation Set (MELIOS). A MELIOS is a hand-held laser range finder containing a single 7X optic. This device is used by Marine FO/FAC units to accurately determine locations of targets for both artillery and close air support missions.

An InterSense inertial sensor-based InertiaCube2 tracker has been mounted on a MELIOS shell with a miniature CRT in place of the optics. 
MELIOS With InterSense Tracker An actual MELIOS is shown here, outfitted with a miniature CRT display where the optics would normally be. The CRT display is driven by a VRSG system providing the "out-the-optic" view. The compass and inclinometer normally mounted on the MELIOS have been replaced with an inertial sensor InterSense InertiaCube2 tracker. The InertiaCube2 feeds orientation data to the VRSG via a serial interface so that the visual system driving the miniature CRT can render the simulated view from the correct perspective with virtually no perceivable latency.


In simulation training facilities, MetaVR visualization software works with simulated hardware. For example, when a simulated LLDR device is coupled with MetaVR's 3D visualization technology, MetaVR VRSG generates the simulated sensor video 3D scene and the range and coordinates of the designated target. When an operator lases on a target, a DIS PDU is transmitted to indicate the range designation information to other simulations on the network.

MetaVR VRSG supports Ascension Technology's Flock of Birds Tracker. Tracking accuracy is unaffected by the nearby presence of conductive metals including aluminum and stainless steel. Other benefits include: no reduction of measurement rates, ability to track up to 4 sensors at a range of up to 3.05 meters, 6 degrees-of-freedom.

VRSG also supports stereo displays, such as the SVGA-Pro I-glasses HMD and system at 800 x 600 and 24- bit resolution.

MetaVR's technology can scale to be portable with notebook computers and low profile head-mounted displays.

MetaVR can scale (up or down) the components to meet your individual price and performance needs. Any immerse display device supporting VGA, S-Video, or NTSC can be integrated with VRSG.

Tracking system support is part of the VRSG product. You can order VRSG directly from MetaVR.
