Abstract

A system and method of operating an audio visual system generating an immersive virtual experience may include generating, by a head-mounted audio visual device, a virtual world immersive experience within a virtual space while physically moving within a physical space, displaying, by the head-mounted audio visual device within the virtual space, a visual target marker indicating a target location in the physical space, receiving, by the head-mounted audio visual device, a teleport control signal, and moving a virtual location of the head-mounted audio visual device within the virtual space from a first virtual location to a second virtual location in response to receiving the teleport control signal.

First claim

What is claimed is:

1. A method, comprising:
generating, by a head-mounted audio visual device, a virtual world immersive experience within a virtual space while physically moving within a physical space;
selecting, by the head-mounted audio visual device, a center or approximate center of the physical space as a target location within the physical space based on determining an approximate center location of a walkable area of the physical space, wherein the selecting the target location does not use a user-placed physical marker;
displaying, by the head-mounted audio visual device within the virtual space, a visual target marker indicating the target location in the physical space;
receiving, by the head-mounted audio visual device, a teleport control signal; and
moving a virtual location of the head-mounted audio visual device within the virtual space from a first virtual location to a second virtual location in response to receiving the teleport control signal.

2. The method of claim 1 wherein the displaying comprises:
displaying, by the head-mounted audio visual device within the virtual space, a visual target marker indicating a center of the physical space.

3. The method of claim 1 wherein the displaying comprises displaying, by the head-mounted audio visual device within the virtual space, a visual target marker indicating a target location in the physical space in response to at least one of the following:
detecting that the head-mounted audio visual device is within a threshold distance of a boundary of the physical space;
detecting that the head-mounted audio visual device has been re-oriented towards the target location in the physical space; and
receiving either the teleport control signal or a signal from a controller to place the head-mounted audio visual device in a teleport mode.

4. The method of claim 1 wherein the displaying comprises:
continuing displaying the visual target marker until the head-mounted audio visual device is within a threshold distance of the target location in the physical space.

5. The method of claim 1 wherein the displaying comprises:
continuing displaying the visual target marker while the head-mounted audio visual device is within a walkable path within the physical space towards the target location or the visual target marker.

6. The method of claim 1 wherein the displaying comprises:
detecting that the head-mounted audio visual device is within a threshold distance of a boundary of the physical space;
performing the following in response to the detecting:
displaying, by the head-mounted audio visual device within the virtual space, a visual target marker indicating a target location in the physical space; and
displaying, by the head-mounted audio visual device within the virtual space, a visual boundary indicating the boundary of the physical space.

7. The method of claim 1 wherein the displaying comprises:
performing the following in response to the receiving the teleport control signal:
displaying, by the head-mounted audio visual device within the virtual space, the visual target marker indicating a target location in the physical space; and
displaying, by the head-mounted audio visual device within the virtual space, a visual boundary indicating the boundary of the physical space.

8. The method of claim 1 wherein the moving comprises:
moving a virtual location of the head-mounted audio visual device within the virtual space from a first virtual location to an object of interest within the virtual space.

9. The method of claim 1 and further comprising:
estimating, by the head-mounted audio visual device, that the head-mounted audio visual device will collide with a boundary of the physical space in less than a threshold period of time; and
displaying, by the head-mounted audio visual device within the virtual space, a visual boundary indicating the boundary of the physical space in response to the estimating.

10. The method of claim 1 and further comprising:
displaying, by the head-mounted audio visual device within the virtual space, a visual boundary indicating the boundary of the physical space at least a threshold period of time before the head-mounted audio visual device is estimated to collide with the boundary of the physical space.

11. An apparatus comprising at least one processor and at least one memory including computer instructions that, when executed by the at least one processor, cause the apparatus to:
generate, by a head-mounted audio visual device, a virtual world immersive experience within a virtual space while physically moving within a physical space;
select, by the head-mounted audio visual device without using a user-placed physical marker, a center or approximate center of the physical space as a target location within the physical space by determining an approximate center location of a walkable area of the physical space;
display, by the head-mounted audio visual device within the virtual space, a visual target marker indicating the target location in the physical space;
receive, by the head-mounted audio visual device, a teleport control signal; and
move a virtual location of the head-mounted audio visual device within the virtual space from a first virtual location to a second virtual location in response to receiving the teleport control signal.

12. A method, comprising:
generating, by a head-mounted audio visual device, a virtual world immersive experience within a virtual space while physically moving within a physical space;
determining, by the head-mounted audio-visual device, an approximate center location of a walkable area of the physical space;
selecting, by the head-mounted audio-visual device without using a user-placed physical marker, the approximate center location as a target location within the physical space;
receiving, by the head-mounted audio visual device, a teleport control signal; and
moving, in response to the teleport control signal, the head-mounted audio visual device from a first virtual location to a second virtual location in the virtual space.

13. The method of claim 12 wherein the moving comprises:
moving, in response to the teleport control signal, the head-mounted audio visual device to a location in the virtual space that corresponds to an approximate center of the physical space.

14. The method of claim 13 wherein the approximate center of the physical space comprises at least one of the following:
a center of the physical space;
any point within a threshold distance of the center of the physical space;
a center of a walkable area of the physical space; and
an interaction distance offset from the center of the physical space.

15. The method of claim 12 wherein the moving further comprises:
shifting, in response to the teleport control signal, the virtual space with respect to the physical space so that an object of interest is displayed at a location in the virtual space that corresponds to a target location in the physical space.

16. The method of claim 12 wherein the moving further comprises:
moving, in response to the teleport control signal, an object of interest in the virtual space to a location in the virtual space that is an interaction distance offset from a target location in the physical space.

17. The method of claim 12 further comprising:
detecting, by the head-mounted audio visual device, that the head-mounted audio visual device has moved to a location within a threshold distance of the target location in the physical space so that a user of the head-mounted audio visual dev
