This paper proves the dramatic benefit to navigation that is produced when participants physically walk through a virtual world. The study used a navigational search task, conducted in a room-sized space. If we can perfect walking interfaces that can be used in large-scale spaces then we will finally solve the well-known problems of disorientation and getting lost that many people suffer from when they navigate in VEs.
