Abstract

A virtual environment can use an absolute orientation framework. An absolute orientation framework in a virtual environment can be activated using an omnidirectional locomotion platform. An absolute orientation framework enables a user's avatar to move independently from the current viewpoint or camera position. The user's avatar can move in an absolute manner relative to a virtual environment map.
