Abstract

Described is a head mounted display device which includes a mounting attachment to attach the head mounted display to a user and a radio frequency transceiver to communicate with a computing device, wherein the computing device formats and transmits video signals for output on the head mounted display. A display screen positionable in front of an eye of the user displays video content included in the video signals transmitted from the computing device.

Claims

1. A head mounted display device, comprising:

a mounting attachment to attach the head mounted display to a user;

a radio frequency transceiver to communicate with a computing device, wherein the computing device formats and transmits video signals for output on the head mounted display; and

a display screen positionable in front of an eye of the user to display video content included in the video signals transmitted from the computing device.

2. The head mounted device as recited in claim 1, wherein the computing device transmits audio signals to the radio frequency transceiver for output on the head mounted display, further comprising:

a sound output device positionable in proximity to an ear of the user to output the audio signals transmitted from the computing device.

3. The head mounted device as recited in claim 1, wherein the radio frequency transceiver receives an action command corresponding to an action of the head mounted display.

4. The head mounted device as recited in claim 3, wherein the radio frequency transceiver transmits a request command to the computing device, the action command being received in response to the request command.

5. The head mounted device as recited in claim 1, wherein the display screen is one of an LCD display and an OLED display.

6. The head mounted device as recited in claim 1, wherein the display screen has a resolution of at least 800×

600 pixels.

7. A head mounted device as recited in claim 1, wherein the radio frequency transceiver communicates with the computing device using Bluetooth.

8. A system comprising of:

a computing device formatting video signals and transmitting the video signals via a radio frequency transceiver; and

a head mounted device including a radio frequency transceiver to receive the video signals from the computing device, a display screen positionable in front of an eye to display video content included in the video signals transmitted from the computing device.

11. The system as recited in claim 8, wherein the computing device communicates via the radio frequency transceiver with one of a local area network and a wide area network.

12. The system as recited in claim 11, wherein the computing device communicates with the one of the local area network and the wide area network using an IEEE protocol.

13. The system as recited in claim 8, wherein the computing device communicates with the head mounted device using Bluetooth.

14. The system as recited in claim 8, wherein the computing device transmits an action command corresponding to an action of the head mounted device.

15. The system as recited in claim 14, wherein the head mounted device transmits a request command to the computing device, the action command being transmitted in response to the request command.

16. The system as recited in claim 15, wherein the computing device maps the request command to the action command.

17. The system as recited in claim 15, wherein the request command is an audio command and the computing device translates the audio command using automatic speech recognition (ASR) software.

18. The system as recited in claim 8, wherein the action command is a non-stateful command.

19. The system as recited in claim 8, wherein the computing device includes power management software which signals the head mounted device to enter a reduced power state.

9. The system as recited in 8, wherein the computing device further transmits audio signals via the radio frequency transceiver, the head mounted device further including a sound output device to output sound included in the audio signals transmitted from the computing device.

10. The system as recited in 8, wherein the computing device includes one of a display, a touchscreen, a keypad, a keyboard, and an audio input/output arrangement.

20. A method, comprising the steps of:

executing an application on a hand held computing device;

configuring display information of the application for a display that is external to the hand held computing device;

transmitting the display information to a head mounted display device, wherein the display information is transmitted via a radio frequency signal; and

displaying the display information on the head mounted display device.
