The following is an example of an installation for a typical CAVE-like environment.
The IS-900 excels over magnetic or optical trackers in CAVE-like installations. As shown in
Figure 20, the SoniStrips are positioned to provide uniform tracking coverage throughout the

Figure 20 - CAVE-like Installation (top down view)
The example above is a 3 meter cube, 4 walled immersive display system which uses six 6-ft.
SoniStrips. Depending of the number of display walls, display volume and mirror position/size, it
may be necessary to use a variety of different sized SoniStrips (6, 4, and 2 foot) or SoniPods
discretely located to provide the optimum tracking coverage. Please consult with InterSense
regarding all CAVE-like installations to maximize the tracking performance.
