Patent ID: 7864168

Claim:
A multiuser physical competition system comprising: a first tracking system for determining changes in a first overall physical location of a first user within a first physical space; a second tracking system for determining changes in a second overall physical location of a second user within a second physical space; and at least one computer operatively coupled to the tracking systems for updating user virtual locations in a virtual space that correspond in a scaled translation to the physical locations of the users, and for determining occurrence of virtual collisions of the users in the virtual space; wherein the at least one computer resolves the virtual collisions in the virtual space; wherein the at least one computer resolves the virtual collisions by selecting a prevailing user for each of the virtual collisions; and wherein the at least one computer resolves the virtual collisions by determining whether the users are considered as having the same posture or as having different postures, and by applying a same-posture resolution criterion if the users have the same posture, or applying a different-posture resolution criterion if the users have different postures.
