CAVE(tm) displays offer many advantages over other virtual reality displays, including a large, unencumbering viewing space. Unfortunately, the typical tracking subsystems used with CAVE(tm) displays tether the user and lessen this advantage. We have designed a simple, low-cost feet tracker that is wireless, leaving the user free to move. The tracker can be assembled for less than $200 US, and achieves an accuracy of 卤10 cm at a 20 Hz sampling rate. We have tested the prototype with two applications: A visualization supporting close visual inspection, and a walkthrough of the campus. Although the tracking was convincing, it was clear that the tracker's limitations make it less than ideal for applications requiring precise visual inspection. However, the freedom of motion allowed by the tracker was a compelling supplement to our campus walkthrough, allowing users to stroll and look around corners.
