Abstract

A control device includes a housing. The control device also includes a wireless communicator interior the housing. The wireless communicator wirelessly sends commands for controlling an electronic device, such as a game console. The control device also includes a reflector positioned to reflect light directed at the housing.

Claims

1. A method, comprising:

receiving one or more infrared images from an infrared camera;

recognizing within one or more of the infrared images an active infrared light emitted from a beacon of a wireless control device; and

after the beacon of the wireless control device stops emitting the active infrared light, recognizing within one or more of the infrared images a passive infrared light reflected from a retroreflector of the control device.

2. The method of claim 1, further comprising sending to the beacon of the wireless control device a command to emit the active infrared light.

3. The method of claim 1, further comprising using a position of the active infrared light to locate the control device in one or more depth images.

4. The method of claim 1, further comprising using a position of the passive infrared light to locate the control device in one or more depth images.

5. The method of claim 4, further comprising assessing a three-dimensional position of the control device from the one or more depth images.

6. The method of claim 5, further comprising tracking the three-dimensional position of the control device over time.

7. A computing device, comprising:

an infrared camera configured to generate one or more infrared images of a scene;

an infrared emitter to illuminate at least a portion of the scene with infrared light;

a logic machine operatively coupled to the camera; and

a storage machine holding instructions executable by the logic machine to;

recognize within one or more of the infrared images an active infrared light emitted from a beacon of a wireless control device; and

after the beacon of the wireless control device stops emitting the active infrared light, recognize within one or more of the infrared images infrared light emitted from the infrared emitter and reflected from a retroreflector of the wireless control device.

8. The computing device of claim 7, further comprising a communication subsystem configured to send to the beacon of the wireless control device a command to emit the active infrared light.

9. The computing device of claim 7, wherein the infrared camera includes a depth camera configured to generate depth images, and wherein the storage machine holds instructions executable by the logic machine to use a position of the active infrared light to locate the control device in one or more of the depth images.

10. The computing device of claim 7, wherein the infrared camera includes a depth camera configured to generate depth images, and wherein the storage machine holds instructions executable by the logic machine to locate the control device in one or more of the depth images based at least in part on a position of infrared light emitted from the infrared emitter and reflected from a retroreflector of the wireless control device.

11. The computing device of claim 10, wherein the storage machine holds instructions executable by the logic machine to assess a three-dimensional position of the control device from the one or more depth images.

12. The computing device of claim 11, wherein the storage machine holds instructions executable by the logic machine to track the three-dimensional position of the control device over time.

13. The computing device of claim 7, further comprising a communication subsystem configured to receive commands from the wireless control device.

14. A computing device, comprising:

a camera input configured to receive one or more infrared images from an infrared camera;

a logic machine operatively coupled to the camera input; and

a storage machine holding instructions executable by the logic machine to;

recognize within one or more of the infrared images an active infrared light emitted from a beacon of a wireless control device; and

after the beacon of the wireless control device stops emitting the active infrared light, recognize within one or more of the infrared images a passive infrared light reflected from a retroreflector of the wireless control device.

15. The computing device of claim 14, further comprising a communication subsystem configured to send to the beacon of the wireless control device a command to emit the active infrared light.

16. The computing device of claim 14, wherein the storage machine holds instructions executable by the logic machine to use a position of the active infrared light to locate the control device in one or more depth images.

17. The computing device of claim 14, wherein the storage machine holds instructions executable by the logic machine to use a position of the passive infrared light to locate the control device in one or more depth images.

18. The computing device of claim 17, wherein the storage machine holds instructions executable by the logic machine to assess a three-dimensional position of the control device from the one or more depth images.

19. The computing device of claim 18, wherein the storage machine holds instructions executable by the logic machine to track the three-dimensional position of the control device over time.

20. The computing device of claim 14, further comprising a communication subsystem configured to receive commands from the wireless control device.
