Virtual Reality Scene Generator (VRSG™) With Tracker Support

MetaVR's visualization software supports 3 or 6 degree-of-freedom (DOF) position tracking technology. This capability totally immerses users in a simulated world with either a handheld 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.

Tracker use with VRSG can range from simulated military devices for target locating and laser designating used by JTACs to the simple NaturalPoint clip-on TrackIR 5.

Commercial tracking systems that VRSG currently supports include:

Flock of Birds Tracker. Ascension Technology's Flock of Birds is a modular DC electromagnetic tracker that captures the position and orientation data of targets through six degrees of freedom (6DOF), with ability to track up to 4 sensors at a range of up to 3.05 meters.
HTC's Vive includes a tracking system that enables you to move around and interact with your virtual environment.

By default, VRSG assumes the Vive’s seated mode setup but you can also setup the Vive in standing or room scale tracking mode. For the latter you must be range of the 6DOF controller you use to navigate the virtual world rendered in VRSG as wand controller support is not yet available.

Inertial Labs' inertial orientation product offerings include weapon orientation, 3D orientation, and attitude and heading reference systems. Military and law enforcement training and simulation applications include head tracking, weapon orientation tracking, virtual and augmented reality and real-time immersive training, and human input devices.
InterSense InertiaCube4 tracker.
Integrating nine discreet miniature inertial sensing elements with advanced Kalman filtering algorithms, the InterSense InertiaCube4 offers sourceless 3DOF tracking with a full 360° range that delivers smooth, precise angular measurements.
VRSG supports stereo displays, such as the SVGA-Pro I-glasses HMD and system at 800 x 600 and 24-bit resolution.
NaturalPoint's TrackIR 5. NaturalPoint's TrackIR 5 6DOF head-tracking input device consists of an infrared camera that sits on the top of a computer monitor and a sensor/tracking clip that you attach to the brim of a baseball cap or visor, which you wear during the VRSG session. The tracking clip has three reflective markers that direct infrared light back to the camera. As you move and rotate your head small amounts while facing the monitor, the camera tracks the position of your head via the tracking clip and the VRSG eyepoint shifts accordingly.

Polhemus SCOUT tracker. The Polhemus SCOUT self-contained 6DOF head- racker eliminates the need for a system electronics unit. The 6DOF helmet mounted sensor communicates its position and orientation directly to the host PC and image generator. The source and sensor microelectronics are fully encapsulated,
providing robust physical and mechanical characteristics.
The SA Photonics SA-62 is a direct view HMD system that provides graphical video via symbology and video imagery over a very wide field of view. SA-62’s high resolution (1920 x 1200) color OLED microdisplays provide a very sharp image. SA Photonics’ innovative prism eyepiece design provides an extremely lightweight HMD.The SA-62 was designed to be mounted to either a helmet or a soft-mount using a standard COTS interface plate.  SA Photonics' SA-62 HMD.
SA Photonics’ SA-92 S SA Photonics’ SA-92/S Augmented Reality HMD is a low cost system that provides augmentation via symbology and video imagery over an extremely wide 92° diagonal field of view. SA-92/S’s high resolution (1920 x 1200) color OLED microdisplays provide a very sharp image. The SA-92/S was designed to be mounted to either a helmet or a soft-mount using a standard COTS interface plate. 
The Sensics zSight™ HMD is offered in in two configurations: regular and helmet-mounted. With high-resolution SXGA OLED displays, 60-degree optics, comfortable and lightweight packaging, low power consumption and integrated tracker, stereo audio and microphone, the zSight is suitable for a variety of training, imaging, tactical display, and remote presence applications.



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 immersive display device supporting VGA, S-Video, or NTSC can be integrated with VRSG.
For fielding in simulation training facilities, VRSG works with simulated military equipment used by forward air controllers (FACs) or JTACs, to illuminate targets for aircraft and artillery strikes. These simulated devices have a tracker embedded in the hardware.

The images to the right and below show a single-channel VRSG integrated with a piece of simulated military equipment with a 3DOF tracker located within the housing.

The device is 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 tracker feeds orientation data to VRSG via a USB interface such that VRSG can render the simulated view from the correct perspective with virtually no perceivable latency.

MetaVR VRSG supports notional devices that use the InterSense InertiaCube4 tracker such as the NVIS Ranger 47 hand-held binocular, which is designed for training and simulation applications. This notional emulated device features dual SXGA OLED microdisplays with focus-adjustable eyepieces displaying a 47 degree diagonal field-of-view (36H x 28V). Stereopsis is supported via two independent video inputs. An external mounting plate accommodates an InertiaCube4 tracker. The Ranger 47 provides 4 programmable USB joystick compatible buttons, plus a z-axis scroll wheel, all of which are interoperable with VRSG to provide laser range and emission of the designator PDU, and thermal views.

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