Abstract

A headset computer that includes a wireless front end that interprets spoken commands and/or hand motions and/or body gestures to selectively activate subsystem components only as needed to carry out specific commands.

Claims

1. A method for controlling a headset computer system that includes a microdisplay, a user input device, a first processor, and two or more peripherals comprising:

entering a first state by enabling only the first processor and user input device;

detecting a user input;

interpreting, with the first processor, the user input as a spoken command or gesture command; and

entering a second state by the first processor issuing a command enabling a selected ones of the two or more peripherals and the first processor issuing a command disabling peripherals based on the spoken command or gesture command.

2. The method of claim 1, wherein the two or more peripherals are selected from a group comprising one or more microphones, for receiving audio signals from the user, a wide area network interface, a communication interface, a second processor, a display, a camera, and a motion detector.

3. The method of claim 2, wherein the motion detector provides two or more motion inputs indicative of user motion, the user motion being along two or more axes.

4. The method of claim 2, wherein the motion detector is a camera for detecting hand and/or body gesture movements of a user.

5. The method of claim 2, wherein the motion detector is a head movement tracking device for detecting head movements of a user.

6. The method of claim 2, wherein the communication interface is configured to provide one or more wireless links between the headset computer and a data processing device.

7. The method of claim 1, wherein the user input is the spoken command, and the spoken command is to access a document, and in the second state, power is applied to a second processor and the microdisplay, and the document is then displayed.

8. The method of claim 1, wherein the user input is the spoken command, and the spoken command is to access a webpage, and the second state further enables a wireless interface to connect to a network to fetch the webpage.

9. The method of claim 1 wherein the user input is a request to manipulate an aspect of the microdisplay, and the second state modifies presentation of information on the microdisplay.

10. The method of claim 1, wherein the first processor further comprises a speech recognizer for processing audio signals to detect the spoken command.

11. The method of claim 1 wherein the first processor is configured to process the command to control aspects of presentation of visual information on the microdisplay.

12. The method of claim 11 wherein the command controls at least one of a field of view, a zoom factor, pan factor, and scale factor.

13. The method of claim 11 wherein the command selects a hyperlink item in a web page display.

14. The method of claim 1, wherein the two or more peripherals are configured to provide one or more peripheral input signals indicating a sensor input or at least one of the gesture command from a user and/or the spoken command from the user.

15. A headset computer comprising:

a microdisplay;

a user input device that provides a user input being a spoken command or a gesture command;

two or more peripheral devices being disabled in a first state;

a first processor configured to translate the user input into one or more commands, only the first processor and the user input device enabled in the first state; and

a processor controller, for selectively enabling and/or disabling the microdisplay and one or more of the two or more peripheral devices, in a second state, based on the one or more commands.

16. The headset computer of claim 15, wherein the two or more peripheral devices are selected from a group comprising one or more microphones, for receiving audio signals from the user, a wide area network interface, a communication interface, a second processor, a display, a camera, and a motion detector.

17. The headset computer of claim 16, wherein the motion detector provides two or more motion inputs indicative of user motion, the user motion being along two or more axes.

18. The headset computer of claim 16, wherein the motion detector is a camera for detecting hand and/or body gesture movements of a user.

19. The headset computer of claim 16, wherein the motion detector is a head movement tracking device for detecting head movements of a user.

20. The headset computer of claim 16, wherein the communication interface is configured to provide one or more wireless links between the headset computer and a data processing device.

21. The headset computer of claim 15, wherein the user input is the spoken command, and the spoken command is to access a document, and in the second state, power is applied to a second processor and the microdisplay, and the document is then displayed.

22. The headset computer of claim 15, wherein the user input is the spoken command, and the spoken command is to access a webpage, and the second state further enables a wireless interface to connect to a network to fetch the webpage.

23. The headset computer of claim 15, wherein the user input is a request to manipulate an aspect of the microdisplay, and the second state modifies presentation of information on the microdisplay.

24. The headset computer of claim 15, wherein the first processor further comprises a speech recognizer, for processing audio signals to detect the spoken command.

25. The headset computer of claim 15 wherein the first processor is configured to process the one or more commands to control aspects of presentation of visual information on the microdisplay.

26. The headset computer of claim 25 wherein the one or more commands control at least one of a field of view, a zoom factor, pan factor, and scale factor.

27. The headset computer of claim 25 wherein the one or more commands select a hyperlink item in a web page display.

28. The headset computer of claim 15, wherein the two or more peripheral devise are configured to provide one or more peripheral input signals indicating a sensor input or at least one of the gesture command from a user and/or the spoken command from the user.
