A training system using haptically enhanced simulations of dental
procedures to provide the sensorimotor involvement needed for dental
training. To provide touch feedback in combination with a realistic
visual experience, the system integrates a haptic stylus interface for
simulating the movement and feel of the tool-tip with a
three-dimensional, stereoscopic display. The haptic stylus enables the
dental student to orient and operate simulated dental tools. Working on a
virtual model viewed in a stereo display, dental students can use a
simulated pick to probe a tooth, or a simulated drill to prepare a tooth
for cavity repair. The touch feedback is simulated by representing these
dental instruments as force-to-a-point tools which map to haptic
simulation procedures executed on a computer workstation that also
provides the visual display.
