definition
sensor fusion of optical and inertial data into one consolidated
output
an inertial measurement unit simultaneously measures 9 phys-
ical properties, i.e. angular rates, linear accelerations (unused)
and magnetic field components (unused) along all 3 axes. This
is achieved using solid state gyroscopes for measurement of roll,
pitch and yaw and optical tracking for drift correction.
position measurement of bodies (subjects or objects) based
upon infrared light and optical measurement procedures
software key to unlock certain capabilities of the tracking system
or SMARTTRACK2/3/M
object either made of retro reflective material or LED for position
tracking (3DOF)
a pointing device which allows to measure the position of the
tool's tip with high accuracy

fully integrated stand-alone infrared optical tracking system with
two cameras and integrated controller, calculates tracking data
and generates the data output stream
compact version of SMARTTRACK3
cameras being in one syncgroup receive the sync signal at the
same time. Syncgroups are distinguished by a short time delay
between their sync signals in order to avoid mutual blinding. (not
