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. Arranging a raster laser projector in a head-worn computer such that it projects a user interface image on to a surface proximate the head-worn computer;

b. Stabilizing the projector and locking the position of the user interface such that the user interface maintains its relative position on the surface during movements of the head-worn computer;

c. Wherein the stabilization of the projector includes physically stabilizing the projector through a gimbaled mount regulated by a head-worn computer motion detection system and digitally stabilizing the user interface image by using a sub portion of a projection field of view of the projector such that the projection can be shifted within the field of view to compensate movements detected by the head-worn computer motion detection system.

7. A method, comprising:

a. Arranging a raster laser projector in a head-worn computer such that it projects a user interface image on to a surface proximate the head-worn computer;

b. Stabilizing the projector and locking the position of the user interface such that the user interface maintains its relative position on the surface during movements of the head-worn computer; and

c. Correcting a shape of the user interface to maintain a proper perspective of the shape, from a user'"'"'s perspective, during the movements of the head-worn computer.

8. The method of claim 7, wherein the correction includes re-aligning the shape of the user interface relative to the surface.

9. The method of claim 7, wherein the correction includes re-aligning the shape of the user interface relative to an edge of the surface.

10. A method, comprising:

a. Arranging a raster laser projector in a head-worn computer such that it projects a user interface image on to a surface proximate the head-worn computer;

b. World-locking the 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.
