PPT (Precision Position Tracking) solutions break the cost-performance barrier, bringing customers high-quality optical tracking to cover very wide ranges (more than 50 x 50 meters) at competitive prices. Optical sensors mounted in the corners of a room track active LED markers.  As sensors move within the room, the sensors acquire data. Through rapid processing, the sensors' data are converted to the accurate three-dimensional location of the markers.

As a real-time system, you see tracking results the instant a subject moves. With the PPT's power and ease of integration with existing real-time rendering tools, the PPT is an ideal solution for real-time applications like VR.

When combined with an off-the-shelf inertial orientation tracker, a PPT hybrid system provides 6DoF motion tracking. The PPT senses the three-dimensional location of the infrared LED markers and quickly transmits the data to a host computer. In this way, PPT can be deployed to track a user in large indoor spaces. WorldViz’s filtering technology allows undisturbed tracking of persons or objects in brightly lit indoor environments (fluorescent or similar lighting).

WorldViz uses a high-speed technique that allows users to calibration systems in minutes. With the sensors oriented in any way that optimises tracking volume, a small four-point calibration board is used for accurately defining the entire tracking volume and the XYZ co-ordinate system.
