term definition
syncgroup 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 (i.e. mutual blinding may be avoided).
synccard (Synccard2/3 or Sync-
cardTP)
plug-in card for the controller which serves for synchronizing the
cameras
Tactile Feedback system for finger-based interactions in immersive virtual reality
applications (wires touch the inside of the finger tips and provide
an impression when they are shortened)
target rigid arrangement of several single markers ( = rigid body)
tracking position measurement of bodies that move in a defined space
TRACKPACK (discontinued) infrared camera
TRACKPACK/C (discontinued) infrared camera dedicated for multi-sided projections
TRACKPACK/E infrared camera
TRACKPACK Controller (discontin-
ued)
calculates tracking data and generates the data output stream
(compatible to TRACKPACK and TRACKPACK/C )
USB radio transceiver (RT2, RT3) exchange data with Flystick or Tactile Feedback
virtual point cloud used for calculating the relative positions of the IR cameras
wand precalibrated stick carrying two markers. The wand belongs to
the room calibration set and is used to generate a virtual point
cloud and to scale the system
