SBIR-STTR Award

This Small Business Innovation Research Phase I project is a 6 DOF tracking device for virtual environment applications based on a patented wireless positioning technology. Realization of such a system will provide a fast, accurate and long range HMD tracker to meet military training demand. The objective of Phase I is to demonstrate technical feasibility of such a system, and to lay solid ground for building a prototype model in Phase II. The proposed system consists of three portable signal transmitters mounted on a helmet, and at least four relay stations in a 3D coordinate system. RF signals emitted from the portable signal transmitters are received by the stations. The position and orientation of the helmet are then determined by TDOA and dynamic calibration method. The proposed system is expected to have wide applications virtual reality and other HMDs.

This SBIR Phase II program is to develop a 6 DOF Head-Tracker for virtual environment applications. An RF 3 DOF transitional tracking system for cordless operation in a long range is currently being developed at Advanced Position Systems, Inc.. A prototype model for such a system was built during the SBIR Phase I program with a positioning accuracy of 2 mm within a range of 5 meters. This prototype model successfully demonstrates the feasibility of the APSI RF tracker. The objective of Phase II is to improve and optimize the prototype model, and to develop a 6 DOF RF/Inertial commercial head-tracker. This 6 DOF tracker is expected to be superior to all existing technologies for cordless operations over long range with no noise, low latency, high sampling rate, no line-of-sight restriction, lightweight, high accuracy, and being insensitive to metallic interference. The realization of such a tracking system will not only greatly enhance the Navy capabilities in future VE training, but also meet an urgent demand from the commercial VE market.
