Researchers at Vienna University have created a virtual reality maze of unlimited size but which can be navigated within a single room (in the real world). The maze is generated as the person walks through the virtual world while maintaining firm boundaries with the confines of the real world room that the person is in (meaning that they won’t walk into real walls). There is a video at the New Scientist website which illustrates the virtual maze in action. There are many potential research applications of this technology.
