Embodiments provide evaluation criteria derived from a motion capture system to trigger movement of the user within a virtual world when the user moves, within an actual space of the environment, from a first location within a first zone to a second location within a second zone. The first zone and the second zone are concentric. ## Claims ### Claim 1 A method for triggering movement of a user in a virtual immersive environment, the method comprising: determining, using a motion capture system, a first location of the user within an actual space of the environment, wherein the actual space of the environment includes a plurality of concentric zones centered about a center point of the actual space of the environment, the plurality of concentric zones includes a first zone and a second zone, the first zone includes the center point and is defined by an outer boundary, the second zone surrounds the first zone and is defined by an inner boundary and an outer boundary, wherein the outer boundary of the first zone coincides with the inner boundary of the second zone, and wherein the first location is within a first zone; determining, using the motion capture system, a second location of the user within the actual space of the environment, wherein the second location is within the second zone; and triggering movement of the user within a virtual world using evaluation criteria derived from the motion capture system when the user moves from the first zone to the second zone. ### Claim 2 (depends on 1) The method of claim 1, wherein movement of the user within the virtual world is not triggered when the user is located in the first zone. ### Claim 3 (depends on 1) The method of claim 1, wherein movement of the user within the virtual world is at a constant speed when the user is located in the second zone. ### Claim 4 (depends on 1) The method of claim 1, wherein movement of the user within the virtual world is at a constant speed when the user is standing still while located in the second zone. ### Claim 5 (depends on 1) The method of claim 1, wherein the plurality of concentric zones further includes a third zone that surrounds the second zone and is defined by an inner boundary and an outer boundary, wherein the outer boundary of the second zone coincides with the inner boundary of the third zone, the method further comprising determining, using the motion capture system, a third location of the user within the actual space of the environment, wherein the third location is within the third zone, and wherein movement of the user in the virtual world is at a greater speed when the user is located in the third zone compared to when the user is located in the second zone. ### Claim 6 (depends on 1) The method of claim 1, wherein the environment is an enclosed structure in which the user is located during implementation of the method. ### Claim 7 (depends on 6) The method of claim 6, wherein the environment is portable. ### Claim 8 (depends on 1) The method of claim 1 further comprising determining, using the evaluation criteria, direction and speed of the user within the virtual world. ### Claim 9 (depends on 1) The method of claim 1, wherein the motion capture system comprises floor sensors provided within the first zone and the second zone that provide feedback data indicative of the location of the user within the actual space of the environment, and wherein the evaluation criteria comprises information corresponding to the feedback data. ### Claim 10 (depends on 1) The method of claim 1, wherein the motion capture system comprises at least one motion capture camera that detects when a user is located within the first zone or the second zone and that provides feedback data indicative of the location of the user within the actual space of the environment, and wherein the evaluation criteria comprises information corresponding to the feedback data. ### Claim 11 A system for triggering movement of a user in a virtual immersive environment, the system comprising: a motion capture system that determines a first location of the user within an actual space of the environment, wherein the actual space of the environment includes a plurality of concentric zones centered about a center point of the actual space of the environment, the plurality of concentric zones includes a first zone and a second zone, the first zone includes the center point and is defined by an outer boundary, the second zone surrounds the first zone and is defined by an inner boundary and an outer boundary, wherein the outer boundary of the first zone coincides with the inner boundary of the second zone, wherein the first location is within a first zone, the motion capture system also determines a second location of the user within the actual space of the environment, and wherein the second location is within the second zone; a sensory interface that receives evaluation criteria derived from the motion capture system, wherein the evaluation criteria is used to trigger movement of the user within a virtual world when the user moves from the first zone to the second zone, and wherein the sensory interface generates sensory messages corresponding to the evaluation criteria; and a sensory output system that receives the sensory messages which instruct the sensory output system to create sensory effects. ### Claim 12 (depends on 11) The system of claim 11, wherein the sensory output system includes at least one imaging device and the sensory effects include video images. ### Claim 13 (depends on 11) The system of claim 11, wherein movement of the user within the virtual world is not triggered when the user is located in the first zone. ### Claim 14 (depends on 11) The system of claim 11, wherein movement of the user within the virtual world is at a constant speed when the user is located in the second zone. ### Claim 15 (depends on 11) The system of claim 11, wherein movement of the user within the virtual world is at a constant speed when the user is standing still while located in the second zone. ### Claim 16 (depends on 11) The system of claim 11, wherein the plurality of concentric zones further includes a third zone that surrounds the second zone and is defined by an inner boundary and an outer boundary, wherein the outer boundary of the second zone coincides with the inner boundary of the third zone, the motion capture system further determines a third location of the user within the actual space of the environment, wherein the third location is within the third zone, and wherein movement of the user in the virtual world is at a greater speed when the user is located in the third zone compared to when the user is located in the second zone. ### Claim 17 (depends on 11) The system of claim 11, wherein the environment is an enclosed structure in which the user is located during operation of the system. ### Claim 18 (depends on 17) The system of claim 17, wherein the environment is portable. ### Claim 19 (depends on 11) The system of claim 11, wherein the evaluation criteria is used to determine direction and speed of the user within the virtual world. ### Claim 20 (depends on 11) The system of claim 11, wherein the motion capture system comprises floor sensors provided within the first zone and the second zone that provide feedback data indicative of the location of the user within the actual space of the environment, and wherein the evaluation criteria comprises information corresponding to the feedback data. ### Claim 21 (depends on 11) The system of claim 11, wherein the motion capture system comprises at least one motion capture camera that detects when a user is located within the first zone or the second zone and that provides feedback data indicative of the location of the user within the actual space of the environment, and wherein the evaluation criteria comprises information corresponding to the feedback data.
