Virtual body modeling apparatus having dual-mode motion processing
First Claim
1. Virtual body modelling apparatus operable to generate and animate under user direction a representation of a body in a virtual environment, the apparatus comprising:
- a first data store, holding data defining the virtual environment;
a second data store, holding data related to features of the virtual body representation;
a user-operable control device;
processing means arranged to generate a representation of the virtual environment based on data from the first data store and from a first viewpoint, to generate the body representation within the virtual environment based on data from the second data store, and to periodically modify the generated body representation in response to signals received from the user-operable control means; and
position determination means arranged to detect a location of said control device relative to a predetermined origin position,said user operable control device comprising a single user actuatable control, andsaid processing means being arranged to either periodically modify said generated body representation or periodically modify the position of the said first viewpoint and regenerate the representation therefrom in dependence on the operation of the user actuatable control.

Abstract
An apparatus is provided for modelling and interacting with a virtual environment. An image of the environment, and a representation of the user'"'"'s presence therein, is generated by a CPU (12) based on data from memories (14,16) and supplied to the user by a stereoscopic display (10). The user is provided with a hand-held unit (18) which has a single control button (20). When the button (20) is not pressed, the user'"'"'s movements of the control (18) are replicated by a modelled icon (such as a virtual hand) within the virtual environment to enable interaction. When the button (20) is actuated, the user'"'"'s movements of control device (18) are instead converted to navigational commands shifting the location of the user'"'"'s virtual presence around the virtual environment.
