Abstract

Briefly, in accordance with one or more embodiments, to implement a meta-display in a head or body worn display system, a display having a first field of view is stored in a memory, and a portion of the first field of view is displayed in a second field of view wherein the first field of view is larger than the second field of view. A position of a user'"'"'s body is detected with a body sensor and a position of the user'"'"'s head is detected with a head sensor. The portion of the first field of view displayed in the second field of view is based on a position of the user'"'"'s head with respect to the user'"'"'s body.

Claims

storing a display having a first field of view in a memory;

displaying at least a portion of the first field of view in a second field of view, the first field of view being larger than the second field of view;

detecting a position of a user'"'"'s body with a body sensor; and

detecting a position of the user'"'"'s head with a head sensor;

wherein the portion of the first field of view displayed in the second field of view is based on a position of the user'"'"'s head with respect to the user'"'"'s body.

2. A method as claimed in claim 1, wherein said detecting a position of the user'"'"'s head comprises detecting a movement of the user'"'"'s head from a first position to a second position, the method further comprising moving the second field of view in response to the movement of the user'"'"'s head to display another portion of the first field of view in the second field of view corresponding to the second position.

3. A method as claimed in claim 1, wherein said detecting a position of the user'"'"'s head comprises detecting a movement of the user'"'"'s head, the method further comprising moving the second field of view proportional to the movement of the user'"'"'s head to display another portion of the first field of view in the second field at a new portion of the first field of view.

4. A method as claimed in claim 1, wherein the display in the first field of view comprises at least some content that is located outside of the second field of view and is not displayed in the second field of view until the user moves the user'"'"'s head toward the content, wherein the content is at least partially displayed in the second field of view in response to the user moving the user'"'"'s head toward the content.

5. A method as claimed in claim 1, wherein said detecting a position of the user'"'"'s body comprises detecting a movement of the user'"'"'s body, the method further comprising moving the first field of view proportional to the movement of the user'"'"'s body to relocate the first field of view to a new location.

6. A method as claimed in claim 1, further comprising controlling a cursor in the first field of view via movement of the user'"'"'s head, the user'"'"'s body, a mouse, or an eye or gaze tracking system, or combinations thereof, to access, select, or manipulate, content in the second field of view.

7. A method as claimed in claim 1, wherein the first field of view comprises one or more regions in which content is displayed, wherein the second field of view is directed to a selected region to display the content in the second field of view in response to detecting an appropriate movement of the user'"'"'s head with respect to the user'"'"'s body via said detecting a position of the user'"'"'s body and said detecting a position of the user'"'"'s head.

8. A method as claimed in claim 1, further comprising detecting a position of the user'"'"'s eyes with an eye tracking sensor, wherein the portion of the first field of view displayed in the second field of view is based at least in part on a position of the user'"'"'s eye'"'"'s.

9. A method as claimed in claim 1, further comprising detecting a position of the user'"'"'s hand, wrist or arm with a manual sensor, wherein the portion of the first field of view displayed in the second field of view is based at least in part on a position of the user'"'"'s hand, wrist or arm.

10. A method as claimed in claim 1, further comprising detecting a position of the user'"'"'s eyes with an eye tracking sensor or detecting a position of the user'"'"'s hand, wrist or arm with a manual sensor, or combinations thereof, wherein the portion of the first field of view displayed in the second field of view is based at least in part on a position of the user'"'"'s eyes or the user'"'"'s hand, wrist or arm, or combinations thereof.

11. A method as claimed in claim 1, further comprising detecting movements of the user'"'"'s eyes with an eye tracking system, wherein the portion of the first field of view displayed in the second field of view is based on a position of the user'"'"'s head with respect to the user'"'"'s body and further controlled by the detected movements of the user'"'"'s eyes.

12. A method as claimed in claim 1, further comprising detecting a gesture of the user'"'"'s hand, wrist or arm with a manual sensor, wherein the portion of the first field of view displayed in the second field of view is based on a position of the user'"'"'s head with respect to the user'"'"'s body and further controlled by the detected gestures of the user'"'"'s hand, wrist or arm.

13. A method as claimed in claim 1, further comprising detecting movements of the user'"'"'s eyes with an eye tracking system or detecting a gesture of the user'"'"'s hand, wrist or arm with a manual sensor, or combinations thereof, wherein the portion of the first field of view displayed in the second field of view is based on a position of the user'"'"'s head with respect to the user'"'"'s body and further controlled by the detected movements of the user'"'"'s eyes or by the detected gestures of the user'"'"'s hand, wrist or arm, or combinations thereof.

14. A display system, comprising:

a memory to store a display having a first field of view;

a photonics module to display a portion of the first field of view in a second field of view, the first field of view being larger than the second field of view;

a body sensor to detect a position of a user'"'"'s body; and

a head sensor to detect a position of the user'"'"'s head;

wherein the portion of the first field of view displayed in the second field of view is based on a position of the user'"'"'s head with respect to the user'"'"'s body.

15. A display system as claimed in claim 14, further comprising a processor coupled to the body sensor and to the head sensor to detect a movement of the user'"'"'s head from a first position to a second position, and to move the second field of view in response to the movement of the user'"'"'s head to display another portion of the first field of view in the second field of view corresponding to the second position.
