Abstract: A virtual reality system is provided in which a user can be guided within a virtual space to a specific destination within a specific time while providing the impression that the user is free to roam the virtual space at will. A leader object or "virtual guide" is projected ahead of the user and is constrained to move along a predetermined path. The user is allowed to move at will within a controlled distance of the leader object. That distance may change depending on the user's location and on elapsed time. Thus the user can be advanced through the virtual reality experience by advancing the leader object.

Abstract: A virtual reality system is provided in which a user can be assured of reaching a destination in a virtual world within a specific time while providing the impression that the user is free to roam the virtual space at will. A virtual leader is projected in front of the user by the system. The virtual leader appears to lead the user but is actually linked to a virtual stick connected to the user, so that as the user moves or turns, the leader moves or turns to stay at substantially the same position relative to the user.
