Sub Millimeter 3D Wireless Positional Tracking for Location Based VR (LBVR)


Virtual Reality (VR) has been around for several years, but the user experience has
been limited to very small spaces. Up until now, extending the space available for
the user experience (enabling user mobility) was extremely expensive and difficult
to setup. In this paper, an affordable, low latency, high precision 3 Dimensional
(3D) wireless tracking system for Location based VR (LBVR) is introduced. This
paper will walk you through the history of positional tracking technology; the
problems with existing tracking for LBVR; and will introduce you to the latest and
greatest tracking solution. This solution integrates three technologies: Ultra Wide
Band (UWB) wireless Radio Frequency (RF), Inertial Measurement Unit (IMU), and
Inside-Out camera Tracking (IOT). The total cost is under $6,000 and requires only
10 minutes to setup.
