Abstract

Aspects of the present invention relate to the projection of imagery from a head-worn computer, wherein a projector with x-y control and a laser are mounted in the head-worn computer and positioned to project a raster style interactive user interface image onto a nearby surface.

Claims

1. A method, comprising:

a. Projecting a user interface image on to a surface proximate a head-worn computer, wherein a laser projector in a head-worn computer produces the projection;

b. World-locking the user interface image relative to the surface; and

c. Assessing movements of the head-worn computer and removing, by modifying what content gets projected, at least a portion of the projected user interface when there is an indication that the at least a portion of the projected user interface is out of a view of the user at the world-locked position.

2. The method of claim 1, wherein the step of assessing movements of the head-worn computer is accomplished by imaging the surface.

3. The method of claim 1, wherein the step of assessing movements of the head-worn computer is accomplished by monitoring data from an IMU on the head-worn computer.

4. The method of claim 1, wherein the at least a portion is a right side portion of the image when the head-worn computer moves to the left.

5. The method of claim 1, wherein the user interface image is a keyboard.

6. The method of claim 1, wherein the user interface image is shape stabilized such that the image maintains a normal shape as the head-worn computer moves.

7. The method of claim 1, wherein interactions with the user interface image are detected through a structured light analysis.
