Abstract:
We describe two instances in which precise mechanical calibration
of virtual environments equipment has been replaced by automated
algorithmic calibration through software that encapsulates the
hardware design and uses a goal-based approach to adjust
calibration parameters. We describe a back-projection system for
adjusting the assumed locations of beacons in a head-mounted
display tracking system; the calculated errors in the navigation
system are used to compute adjustments to the beacon positions to
reduce such errors. In a second application, a piggyback headtracking/hand-tracking system is calibrated by a similar reduction
of computed errors.
