Abstract

A virtual reality (VR) system includes an image playback system that sends images to an image viewing device, such as a pair of display glasses. Each image has a 360-degree field of view. An user views a portion of the images. The portion of the image viewed is determined by a directional sensor mounted to the display glasses. The images are advanced according to a speed sensor attached to a moving device, such as a stationary bicycle. The VR system simultaneously coordinates the portion of the images viewed by the user by coordinating signals from the directional sensor and the speed sensor.

Claims

1. A virtual reality (VR) system comprising:

an image playback system having a storage device for maintaining a plurality of images where each image has a field-of-view defining an X direction and a Y direction;

an image viewing device operatively communicating with said image playback system for displaying a portion of said plurality of images to a user;

a directional sensor operatively communicating with said playback system for defining a viewing direction of the user in both of said X and Y directions;

a forward and rearward moving device for defining a Z direction; and

a speed sensor operably connected to said moving device and operatively communicating with said playback system for providing a rate of change of said plurality of images in said Z direction;

said VR system characterized by said image playback system having a controller operatively connected to said storage device for simultaneously coordinating said X and Y directions of said directional sensor and said Z direction of said speed sensor such that said viewing direction and said rate of change are interlaced to automatically change said portion of said plurality of images displayed by said image viewing device in said X, Y, and Z directions when the user moves the directional sensor in at least one of the X and Y directions and simultaneously moves the moving device in the Z direction.

2. A VR system as set forth in claim 1 wherein said controller automatically changes said portion of said images displayed by said image viewing device throughout said field-of-view.

3. A VR system as set forth in claim 1 wherein said field-of-view is further defined as 360 degrees in the X direction and 180 degrees in the Y direction.

4. A VR system as set forth in claim 3 wherein said portion of said plurality of images is further defined as approximately 140 degrees in the X direction and 90 degrees Y direction.

5. A VR system as set forth in claim 1 wherein said image viewing device is further defined as display glasses adapted to be worn by the user.

6. A VR system as set forth in claim 5 wherein said directional sensor is attached to said display glasses such that said portion of said plurality of images automatically changes as said glasses move in said X and Y directions.

7. A VR system as set forth in claim 1 wherein said image playback system includes a first wireless interface for communicating with said speed sensor and said directional sensor.

8. A VR system as set forth in claim 7 wherein said speed sensor includes a second wireless interface for communicating with said first wireless interface of said playback system.

9. A VR system as set forth in claim 7 wherein said directional sensor includes a third wireless interface for communicating with said first wireless interface of said playback system.

10. A VR system as set forth in claim 1 wherein said forward and rearward moving device is further defined as an exercise apparatus for allowing a user to exercise.

11. A VR system as set forth in claim 10 wherein said speed sensor is operatively connected to said exercise apparatus and is operational as the user exercises.

12. A VR system as set forth in claim 1 wherein said plurality of images are compressed for increasing an amount of images stored on said storage device.

13. A VR system as set forth in claim 1 wherein said image playback system further includes a frame buffer operatively communicating with said image viewing device for displaying said portion of said plurality of images to the user at a constant frame rate.

14. A method of operating a virtual reality (VR) system comprising:

maintaining a plurality of images where each image has a 360-degree field-of-view defining a X direction and a Y direction;

determining a viewing direction of a user in both of the X and Y directions;

displaying a portion of the plurality of images to the user; and

sensing a rate of change of the plurality of images moving in a Z direction;

the method characterized by simultaneously coordinating the X and Y directions and the Z direction and interlacing the viewing direction and the rate of change for automatically changing the plurality of images in the X, Y, and Z directions as the user changes the viewing direction in at least one of the X and Y directions and simultaneously moves in the Z direction.

15. A method as set forth in claim 14 wherein the step of automatically changing the plurality of images is further defined as automatically changing the plurality of images in the X, Y, and Z directions throughout the 360-degree field-of-view.

16. A method as set forth in claim 14 wherein the step of maintaining the plurality of images is further defined as compressing the plurality of images and storing the plurality of images.

17. A method as set forth in claim 16 wherein the step of displaying the portion of the plurality of images is further defined as decompressing the images.

18. A method as set forth in claim 14 wherein the step of determining a viewing direction of a user is further defined as monitoring any movement of the user.

19. A method as set forth in claim 14 wherein the step of coordinating the X and Y directions and the Z direction is further defined as communicating across one or more wireless interfaces.

20. A method as set forth in claim 14 wherein the step of displaying a portion of the plurality of images to the user is further defined as displaying a portion of the plurality of images to the user at a constant frame rate.
