The Tracker plugs into your serial port and delivers
3 dimensional, 6 degrees of freedom (x, y, z, pitch, yaw,
roll) control. Up to four HeadTrackers can be connected
together to act simultaneously in VR or Simulation
applications. Ultrasonic technology eliminates metal or
display interference.

The Logitech Head Tracker consists of a transmitter,
helmet-mountable receiver and control box. The
transmitter contains 3 speakers which emit ultrasonic
signals and the receiver contains 3 miniature
microphones to sense these signals. The transmitter and
receiver communicate along a line of sight, facing each
other. Both devices contain mounting holes to facilitate
mounting in a wide variety of configurations. A control
box is connected to both devices and determines the
position of the receiver based on the timing of the
microphone signals. Driver Software Head Tracker is
shipped with driver software for PC and SGI platforms.
