Abstract
The invention relates to a 3-dimensional computer graphics system in which an operator can effectively interact with a virtual model generated and displayed by a computer. In one embodiment the operator wears a helmet fitted with means which enable both the location of his head and its coordinates relative to the virtual model to be monitored and the information sent to computer. The helmet carries miniature VDUs which direct separate images to his individual eyes so that the image is perceived stereoscopically. The movement of the operator's eyes is also monitored by means mounted within housings of the helmet and data representing the operator's direction of vision sent to the computer. The data transmitted to the computer is used to modify the image of the model as perceived by the operator to enhance its realism.
