<p>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.</p> |
