Virtual environment navigation and interaction apparatus and method

摘要

In an interactive entertainment apparatus, where a user is presented with an image of a virtual environment and enabled to move the image viewpoint location and direction within the environment, a control arrangement is provided for movable or animated characters or artefacts appearing within the environment. Variables (distance, theta) are generated determining the separation between the viewpoint and artefact and divergence of viewpoint direction. Changes in one or both of these values initiates a controlled sequence (104.C/F) of poses adopted by all or part of the artefact.
