Mode 2 is recommended for use with HMD or other immersive
applications. Drift correction adjustments are made smoothly
and only while the sensor is moving, so as to be transparent to
the user.
Sensitivity Level This setting is only used when Perceptual Enhancement Level
is set to 2. It controls the minimum angular rotation rate
picked up by the MicroTrax inertial components. Default is
level 3. Increasing sensitivity does not increase latency during
normal movements. It may result in some small residual
movements for a couple of seconds after the sensor has
stopped. If your application requires sensitivity greater than
the maximum provided by this control, you must use
Perceptual Enhancement level 0 or 1 instead.
Prediction Value IS-900 can predict motion up to 50 ms into the future, which
compensates for graphics rendering delays and further
contributes to eliminating simulator lag.
Tip Offset Defines a set of position offsets, so a different point can be
tracked. Offsets are measured in the body coordinate frame of
the MicroTrax station and are entered in centimeters.
Sensor Rotation Sets boresight reference angles in degrees for the specified
station.
