Abstract

A pair of handheld controllers with asymmetric tracking patterns for use with a tracking camera. The pair of controllers includes a right-hand controller and a left-hand controller. The right-hand and the left-hand controllers are substantially symmetric with respect to each other with the exception of their respective tracking patterns. A right-hand pattern of lights is disposed on the right-hand controller and a left-hand pattern of lights is disposed on the left-hand controller. The right-hand pattern of lights and the left-hand pattern of lights are asymmetric with respect to each other. The right-hand controller includes a right-hand handle portion and a surrounding right-hand ring portion and the left-hand controller includes a left-hand handle portion and a surrounding left-hand ring portion. The right-hand pattern of lights and the left-hand pattern of lights are disposed on the right-hand ring portion and the left-hand ring portion, respectively.

Claims

1. A pair of handheld controllers for use with a tracking camera, the pair of controllers comprising:

a right-hand controller and a left-hand controller, wherein the right-hand and the left-hand controllers are substantially symmetric with respect to each other when adjacent to each other in a similar orientation relative to a plane between the left-hand and right-hand controllers;

a right-hand pattern of lights trackable by the tracking camera disposed on the right-hand controller and a left-hand pattern of lights trackable by the tracking camera disposed on the left-hand controller, wherein the right-hand pattern of lights and the left-hand pattern of lights are asymmetric with respect to each other when the left-hand and right-hand controllers are adjacent to each other in the similar orientation.

2. The pair of handheld controllers of claim 1, wherein the right-hand controller includes a right-hand handle portion connected to a surrounding right-hand ring portion, and wherein the left-hand controller includes a left-hand handle portion connected to a surrounding left-hand ring portion.

3. The pair of handheld controllers of claim 2, wherein the right-hand pattern of lights and the left-hand pattern of lights are disposed on the right-hand ring portion and the left-hand ring portion, respectively.

4. The pair of handheld controllers of claim 3, wherein the right-hand pattern of lights and the left-hand pattern of lights each comprises first and second rows of lights positioned around the outer circumference of their respective ring portions.

5. The pair of handheld controllers of claim 4, wherein the first row of lights is positioned adjacent a forward edge of the respective ring portion, the lights of the first row of lights are positioned at alternating first and second distances from the forward edge.

6. The pair of handheld controllers of claim 4, wherein the second row of lights is positioned adjacent a rear edge of the respective ring portion, the lights of the second row are positioned at approximately the same distance from the rear edge.

7. The pair of handheld controllers of claim 1, wherein the right-hand and left-hand handle portions include a right-hand handle pattern of lights and a left-hand handle pattern of lights, respectively, wherein the right-hand and left-hand handle patterns are symmetric with respect to each other when the left-hand and right-hand controllers are adjacent to each other in the similar orientation.

8. The pair of handheld controllers of claim 1, wherein the right-hand pattern of lights and the left-hand pattern of lights each comprise a plurality of infrared light emitting diodes.

9. A pair of handheld controllers for use with a tracking camera, the pair of controllers comprising:

a right-hand controller, including;

a right-hand handle portion,

a first right-hand pattern of tracking features disposed on the right-hand handle, and

a surrounding right-hand ring portion;

a left-hand controller, including;

a left-hand handle portion,

a first left-hand pattern of tracking features disposed on the left-hand handle, and

a surrounding left-hand ring portion;

wherein the right-hand and the left-hand controllers are substantially symmetric with respect to each other when adjacent to each other in a similar orientation relative to a plane between the left-hand and right-hand controllers;

a second right-hand pattern of tracking features disposed on the right-hand controller; and

a second left-hand pattern of tracking features disposed on the left-hand controller, wherein the second right-hand pattern of tracking features and the second left-hand pattern of tracking features are asymmetric with respect to each other when the left-hand and right-hand controllers are adjacent to each other in the similar orientation.

10. The pair of handheld controllers of claim 9, wherein the second right-hand pattern of tracking features and the second left-hand pattern of tracking features are disposed on the right-hand ring portion and the left-hand ring portion, respectively.

11. The pair of handheld controllers of claim 10, wherein the second right-hand pattern of tracking features and the second left-hand pattern of tracking features each comprises first and second rows of tracking features positioned around the outer circumference of their respective ring portions.

12. The pair of handheld controllers of claim 11, wherein the first row of tracking features is positioned adjacent a forward edge of the respective ring portion, the tracking features of the first row are positioned at alternating first and second distances from the forward edge.

13. The pair of handheld controllers of claim 12, wherein the second row of tracking features is positioned adjacent a rear edge of the respective ring portion, the tracking features of the second row are positioned at approximately the same distance from the rear edge.

14. The pair of handheld controllers of claim 9, wherein the tracking features comprise lights trackable by the tracking camera.

15. A handheld controller for use with a tracking camera, comprising:

a controller, including;

a handle portion,

a surrounding ring portion connected to the handle portion; and

first and second rows of tracking features positioned around the outer circumference of the ring portion;

wherein the tracking features of the first row of tracking features are positioned adjacent a forward edge of the ring portion at alternating first and second distances from the forward edge, and wherein the tracking features of the second row of tracking features are positioned adjacent a rear edge of the respective ring portion at approximately the same distance from the rear edge.

16. The handheld controller of claim 15, wherein the tracking features of the second row of tracking features are positioned at alternating circumferential distances between the tracking features.

17. The handheld controller of claim 16, wherein the controller is a first controller and further comprising a second controller, wherein the first and second controllers are substantially symmetric with respect to each other when adjacent to each other in a similar orientation relative to a plane between the first and second controllers.

18. The handheld controller of claim 17, wherein the first and second rows of tracking features define a first pattern of tracking features and further comprising a second pattern of tracking features disposed on the second controller, wherein the first pattern of tracking features and the second pattern of tracking features are asymmetric with respect to each other when the first and second controllers are adjacent to each other in the similar orientation.
