Abstract

Aspects of the present invention relate to methods and systems for positioning content within an FOV of a HWC based on sensor feedback.

Claims

1. A method, comprising:

a. Presenting content at a position within a field of view of a head-worn see-through display; and

b. Repositioning the content within the field of view based on a changed sight-heading of the head-worn display, wherein the repositioning occurs at a speed; and

c. Wherein the speed of the repositioning is damped and creates a misalignment of the content with a position consistent with the changed sight-heading if the sight-heading changes at a rate above a predetermined threshold.

2. The method of claim 1, wherein the rate of change of the sight-heading is indicative of a high rate of change of head direction.

3. The method of claim 1, wherein the rate of change of the sight-heading is indicative of a high rate of back and forth head direction.

4. The method of claim 1, wherein the misalignment is not perceived by a user of the head-worn see-through display due to the sight-heading rate of change.

5. The method of claim 1, wherein the speed of the repositioning is further dependent on an eye-heading rate of change.

6. The method of claim 1, wherein the step of presenting the content at a position within the field of view of the head-worn see-through display involves producing image light at a front-lit reflective display.

7. The method of claim 6, wherein the reflective display is a DLP with a dark light trap.

8. The method of claim 6, wherein the reflective display is an LCoS.

9. The method of claim 6, wherein the head-worn see-through display includes an eye imaging system.

10. The method of claim 1, wherein the user interacts with the content with an external user interface.
