Figure 5-1. Three-Dimensional Axes and Rotation
The 3D Mouse and Head Tracker systems use two right-hand rules to
help you determine position and orientation. The first right-hand rule
allows you to hold your thumb, index finger, and middle finger of the
right hand at right angles to each other to indicate the positive direction
of the X, Y, and Z axes (see Figure 5-2).
