Virtual coatings application system

A virtual coatings application system has several features to enhance the realism of simulated spray painting. The system generally includes a display screen on which is defined a virtual surface (such as a truck door) that is intended to be virtually painted or coated by the user. Alternatively, the system includes a head-mounted display unit that displays a virtual spray painting environment in which the virtual surface is defined. The user operates an instrumented spray gun controller that outputs one or more signals representing data as to the status of the controls on the spray gun controller. The system also has a motion tracking system that tracks the position and orientation of the spray gun controller with respect to the virtual surface. Simulation software generates virtual spray pattern data in response to at least the data from the spray gun controller and the position and orientation data received from the tracking system. Virtual spray pattern images are displayed in real time on the virtual surface in accordance with the accumulation of virtual spray pattern data at each location on the virtual surface.

Methods and apparatus for simulating dental procedures and for training dental students

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.
