Improved Tracking Using a Hybrid Optcial-Haptic Three-Dimensional Tracking System
Abstract : The aim of this paper is to asses to what extent an
optical tracking system (OTS) used for position tracking in
virtual reality can be improved by combining it with a human
scale haptic device named Scalable-SPIDAR. The main
advantage of the Scalable-SPIDAR haptic device is the fact it is
unobtrusive and not dependent of free line-of-sight.
Unfortunately, the accuracy of the Scalable-SPIDAR is affected
by bad-tailored mechanical design. We explore to what extent the
influence of these inaccuracies can be compensated by collecting
precise information on the nonlinear error by using the OTS and
applying support vector regression (SVR) for calibrating the
haptic device reports. After calibration of the Scalable-SPIDAR
we have found that the average error in position readings
reduced from to 263.7240±75.6207 mm to 12.6045±8.4169 mm.
These results encourage the development of a hybrid hapticoptical
system for virtual reality applications where the haptic
device acts as an auxiliary source of position information for the
optical tracker.
