Professor Ruiz & Matthew Schumaker with the RPI hat which has the inertia cube (sensing angular rate of rotation and linear acceleration along 3 perpendicular axes which are transformed into a reference coordinate frame and integrated to keep track of changes in position (x, y, z)) & ultrasonic discs (to determine time of flight distance measurements).

Motion Tracking
The High End: inertial/ultrasonic sensing technology We have created one of the first successful motion tracker interfaces to on-line 3D scenes in VRML (virtual reality modeling language) using the InterSense IS600 Precision Motion Tracker which was graciously donated for one year to The Landscape of Perception Project. We used the tracker for exact high-fidelity 6 Degree-of-Freedom (x,y,z & pitch, yaw, roll) position and orientation tracking. The IS600 utilizes a hybrid of inertial and ultrasonic sensing technologies with drift correction and angular rate acceleration sensors which provided us with accurate feed-forward motion prediction. Update rates were 180 Hz with extremely low latency. Tracker-induced lag was removed from the virtual environment through the use of the proprietary micro-machined inertial sensor unit and signal processing drift error algorithms. Using this device and the open source code of the Blaxxun 3D web plug in, we were able navigate physically thorough an on-line virtual environment without the use of any consoles or representation system.
The Low End: the simple keyboard We are also working on creating simple keyboard interface that uses conventional gaming strokes to interface to VRML scenes. Additionally, we are programming a multi-user virtual environment landscape where numerous people can participate in a similar virtual environment.

We are also seeking to work with cognitive scientists and educators to develop educational gaming for at-risk youth.
