Abstract

A system and method for providing a virtual reality game controller with improved functionality by providing capacitive touch and proximity sensors on the controller to enable additional feedback to the user such that interaction with a physical object such as a game controller may be translated into interaction with a virtual tool in a virtual environment such as providing a visual indication in the virtual environment that a finger or thumb is approaching a button of a physical game controller.

Claims

1. A method for providing feedback to a user in a virtual reality environment, said method comprising the steps of:

providing a virtual environment that is visible to the user;

providing a physical game controller;

providing a virtual object that represents the physical game controller but within the virtual environment;

disposing at least one proximity sensor on the physical game controller, wherein the at least one proximity sensor will detect an object approaching the at least one proximity sensor before contact is made;

detecting an object approaching the at least one proximity sensor on the physical game controller; and

providing a visual indicator in the virtual environment that the object is approaching the physical game controller.

2. The method as defined in claim 1 wherein the method further comprises providing the visual indicator on the virtual object that the object is approaching the physical game controller.

3. The method as defined in claim 2 wherein the method further comprises changing the visual indicator to thereby indicate a distance of the object from the physical game controller.

4. The method as defined in claim 3 wherein the method further comprises:

1) creating a first feature on the physical game controller that is activated by touch and deactivated when touch is withdrawn; and

2) disposing the at least one proximity sensor on the first feature.

5. The method as defined in claim 4 wherein the method further comprises selecting the first feature from the plurality of features comprised of a button, a trigger, a keyboard, a pad, and a dial.

6. The method as defined in claim 5 wherein the method further comprises providing a plurality of features on the physical game controller.

7. The method as defined in claim 3 wherein the method further comprises selecting the visual indicator from the group of visual indicators comprised of an illuminated surface, an illuminated ring on a surface, and a plurality of concentric illuminated rings on a surface.

8. The method as defined in claim 7 wherein the method further comprises changing an intensity of illumination of the visual indictor in order to indicate the distance of the object from the physical game controller.

9. The method as defined in claim 7 wherein the method further comprises changing the number of the concentric illuminated rings that are illuminated in order to indicate the distance of the object from the physical game controller.

10. The method as defined in claim 2 wherein the method further comprises providing a location of the object that is approaching the physical game controller on the virtual object by using the visual indicator to show the location on the virtual object that is perpendicular to the object relative to the physical game controller.

11. A system for providing feedback to a user in a virtual reality environment, said system comprised of:

a virtual environment that is visible to the user;

a physical game controller;

a virtual object that represents the physical game controller but within the virtual environment;

at least one proximity sensor disposed on the physical game controller, wherein the at least one proximity sensor will detect an object approaching the at least one proximity sensor before contact is made; and

a visual indicator in the virtual environment that indicates that the object is approaching the physical game controller.

12. The system as defined in claim 11 wherein the system is further comprised of the visual indicator being disposed on the virtual object.

13. The system as defined in claim 12 wherein the system is further comprised of the visual indicator indicating a distance of the object from the physical game controller.

14. The system as defined in claim 13 wherein the system is further comprised of a first feature disposed on the physical game controller that is activated by touch and deactivated when touch is withdrawn, wherein the at least one proximity sensor is disposed on the first feature.

15. The system as defined in claim 14 wherein the system is further comprised of selecting the first feature from the plurality of features comprised of a button, a trigger, a keyboard, a pad, and a dial.

16. The system as defined in claim 15 wherein the system is further comprised of a plurality of features disposed on the physical game controller.

17. The system as defined in claim 13 wherein the system is further comprised of selecting the visual indicator from the group of visual indicators comprised of an illuminated surface, an illuminated ring on a surface, and a plurality of concentric illuminated rings on a surface.

18. The system as defined in claim 17 wherein the system is further comprised of the visual indictor changing an intensity of the illumination in order to indicate the distance of the object from the physical game controller.

19. A method for providing feedback to a user in a virtual reality environment, said method comprising the steps of:

providing a virtual environment that is visible to the user;

providing a physical game controller;

providing a virtual object that represents the physical game controller but within the virtual environment;

disposing at least one proximity sensor on the physical game controller, wherein the at least one proximity sensor will detect an object approaching the at least one proximity sensor before contact is made;

detecting an object approaching the at least one proximity sensor on the physical game controller; and

providing a visual indicator in the virtual environment that the object is approaching the physical game controller, and changing the visual indicator to thereby indicate a distance of the object from the physical game controller.
