Abstract

A head-mounted display (HMD) is provided, including the following: a transceiver; a plurality of antenna arrays; a selector configured to determine which of the antenna arrays is active for wireless communication of data by the transceiver; a display configured to render video data received by the transceiver through the active antenna array.

Claims

1. A head-mounted display (HMD), comprising:

a transceiver;

a plurality of antenna arrays respectively disposed in a plurality of sides of the HMD, the plurality of sides of the HMD including a front side, a lateral side, and a rear side of the HMD;

a selector configured to determine which of the antenna arrays is active for wireless communication of data by the transceiver;

a display configured to render video data received by the transceiver through the active antenna array.

2. The head-mounted display of claim 1, wherein the selector is configured to measure signal strength through each of the antenna arrays, and determine which of the antenna arrays is active for wireless communication based on the measured signal strengths.

3. The head-mounted display of claim 2, wherein the selector is configured to define the antenna array with the highest measured signal strength to be the active antenna array.

4. The head-mounted display of claim 1, wherein the selector is configured to determine which of the antenna arrays is active for wireless communication based on a location or orientation of the HMD in an interactive environment.

5. The head-mounted display of claim 4, further comprising:

at least one inertial sensor configured to detect the location or orientation of the HMD.

6. The head-mounted display of claim 4, further comprising:

at least one sensor configured to detect one or more emitters in an interactive environment in which the HMD is disposed, to enable determination of the location or orientation of the HMD.

7. The head-mounted display of claim 6, wherein the sensor is a camera, photo sensing diode, or magnetic sensor.

8. A system, comprising:

a head-mounted display (HMD);

a beamforming transceiver configured to have a beamforming direction that is adjusted towards the HMD;

wherein the HMD includes,

an HMD transceiver,

a plurality of antenna arrays respectively disposed in a plurality of sides of the HMD, the plurality of sides of the HMD including a front side, a lateral side, and a rear side of the HMD,

a selector configured to determine which of the antenna arrays is active for wireless communication of data between the HMD transceiver and the beamforming transceiver, and

a display configured to render video data received from the beamforming transceiver by the HMD transceiver through the active antenna array.

9. The system of claim 8, wherein the selector is configured to measure signal strength through each of the antenna arrays, and determine which of the antenna arrays is active for wireless communication based on the measured signal strengths.

10. The system of claim 9, wherein the selector is configured to define the antenna array with the highest measured signal strength to be the active antenna array.

11. The system of claim 8, wherein the selector is configured to determine which of the antenna arrays is active for wireless communication based on a location or orientation of the HMD in an interactive environment.

12. The system of claim 11,

wherein the HMD further includes,

at least one inertial sensor configured to detect the location or orientation of the HMD.

13. The system of claim 11, further comprising:

one or more emitters;

wherein the HMD further includes,

at least one sensor configured to detect the one or more emitters, to enable determination of the location or orientation of the HMD.

14. The system of claim 13, wherein the sensor is a camera, photo sensing diode, or magnetic sensor.

15. The system of claim 8,

wherein the beamforming transceiver is configured to have a beamforming direction that is adjusted towards the active antenna of the HMD.

16. A method, comprising:

in a head-mounted display (HMD) having a plurality of antenna arrays respectively disposed in a plurality of sides of the HMD, the plurality of sides of the HMD including a front side, a lateral side, and a rear side of the HMD, monitoring a signal strength of a wireless signal through each of the antenna arrays;

selecting, based on the monitored signal strengths, one of the antenna arrays of the HMD as an active antenna array for wireless communication of data between the HMD and an external transceiver;

receiving video data through the active antenna array of the HMD;

rendering the received video data to a display of the HMD.

17. The method claim 16, wherein the antenna array with the highest measured signal strength is selected as the active antenna array.

18. The method of claim 16, further comprising:

determining a location or orientation of the HMD in an interactive environment;

wherein selecting which of the antenna arrays is active for wireless communication is further based on the location or orientation of the HMD in the interactive environment.

19. The method of claim 18, wherein determining the location or orientation of the HMD includes detecting inertial data through at least one inertial sensor of the HMD.

20. The method of claim 18, wherein determining the location or orientation of the HMD includes detecting, via one or more sensors of the HMD, one or more emitters in an interactive environment in which the HMD is disposed.
