Arranging the Head Tracker Components
Custom Head Tracker Arrangements
8
Arrange the Head Tracker components as discussed in the previous
section "Arranging the 3D Mouse Components." However, when using
the Head Tracker, the transmitter does not have to be parallel with the
plane of the host computer's monitor.
The Head Tracker transmitter and receiver have screw holes so you can
mount them onto almost any custom device you design for your specific
needs. This section shows two custom devices designed by two hardware
developers that incorporate the Head Tracker components.
The first device, which appears in Figure 2-4, shows a head-mounted
image display designed by the Virtual Research company. The Head
Tracker receiver is mounted onto the top of the Virtual Research
helmet. The transmitter must be mounted overhead, within range, and
in a direct line of communication with the receiver. The image on the
display adjusts to movements of the user's head.
