Wide-area Optical Motion Tracking
PPT (Precision Position Tracking) solutions break the cost-performance barrier, bringing customers high-quality optical motion tracking to cover very wide ranges (more than 50 x 50 meters) at competitive prices.
And the PPT product family continues to grow, bringing more functionality and ease of use to new and existing customers alike. As a real-time system, you get to see tracking results the instant a subject performs a motion. With the system’s power and ease of integration with existing real-time rendering tools, the PPT is an ideal solution for real-time applications such as Virtual Reality.
Optimized for Virtual Reality Applications
PPT tracks large areas (more than 50 x 50 meters) while maintaining high precision and accuracy. It presents excellent value for the real-time demands of immersive virtual reality applications. When combined with an off-the-shelf inertial orientation tracker, a PPT hybrid system provides 6DOF motion tracking with unparalleled performance and at an unbeatable price. Experience what you have been missing, start tracking wide areas today!
Calibration: Easy as one, two, three
WorldViz uses a high-speed technique that allows users to calibrate systems in mere minutes. With the sensors oriented in any way that optimizes your tracking volume, a small four-point calibration board is used for accurately defining the entire tracking volume and XYZ coordinate system. Since our systems uses factory calibrated lenses, you never need to be concerned about obtaining a satisfactory sensor linearization and you can rest assured that your workspace will calibrate quickly and robustly.

(**) For a marker to be tracked, it must be visible by two or more cameras. Overall tracking space dimensions are determined by the camera range, camera layout, and background lighting
How does it work?
Optical sensors mounted in the corners of a room track active LED markers. As sensors make their way through the room, the sensors acquire data. Through rapid processing, the sensors’ data are converted to the accurate three-dimensional location of the markers.
