A system and method for permitting three-dimensional navigation through a virtual reality environment using camera-based gesture inputs of a system user. The system comprises a computer-readable memory, a video camera for generating video signals indicative of the gestures of the system user and an interaction area surrounding the system user, and a video image display. The video image display is positioned in front of the system user. The system further comprises a microprocessor for processing the video signals, in accordance with a program stored in the computer-readable memory, to determine the three-dimensional positions of the body and principle body parts of the system user. The microprocessor constructs three-dimensional images of the system user and interaction area on the video image display based upon the three-dimensional positions of the body and principle body parts of the system user. The video image display shows three-dimensional graphical objects within the virtual reality environment, and movement by the system user permits apparent movement of the three-dimensional objects displayed on the video image display so that the system user appears to move throughout the virtual reality environment.

A medical system that allows a mentor to teach a pupil how to use a robotically controlled medical instrument. The system may include a first handle that can be controlled by a mentor to move the medical instrument. The system may further have a second handle that can be moved by a pupil to control the same instrument. Deviations between movement of the handles by the mentor and the pupil can be provided as force feedback to the pupil and mentor handles. The force feedback pushes the pupil's hand to correspond with the mentor's handle movement. The force feedback will also push the mentor's hand to provide information to the mentor on pupil's movements. The mentor is thus able to guide the pupil's hands through force feedback of the pupil handles to teach the pupil how to use the system.

A virtual computer monitor is described which enables instantaneous and intuitive visual access to large amounts of visual data by providing the user with a large display projected virtually in front of the user. The user wears a head-mounted display containing a head-tracker, which together allow the user to position an instantaneous viewport provided by the head-mounted display at any position within the large virtual display by turning to look in the desired direction. The instantaneous viewport further includes a mouse pointer, which may be positioned by turning the user's head, and which may be further positioned using a mouse or analogous control device. A particular advantage of the virtual computer monitor is intuitive access to enlarged computer output for visually-impaired individuals.

The system allows training and qualification of a user performing a skill-related training exercise involving body motion in a workspace. A training environment is selected through a computer apparatus, and variables, parameters and controls of the training environment and the training exercise are adjusted. Use of an input device by the user is monitored. The 3D angles and spatial coordinates of reference points related to the input device are monitored through a detection device. A simulated 3D dynamic environment reflecting effects caused by actions performed by the user on objects is computed in real time as a function of the training environment selected. Images of the simulated 3D dynamic environment in real time are generated on a display device viewable by the user as a function of a computed organ of vision-object relation. Data indicative of the actions performed by the user and the effects of the actions are recorded and user qualification is set as a function of the recorded data.
