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.
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.
