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. Projecting a pattern of light of a non-visible wavelength, wherein the pattern of light overlaps the user interface image, wherein disruptions detected in the pattern are interpreted as user interactions with the user interface image; and

d. Causing the user interface image and the pattern of light maintain their relative shapes and to remain in an overlapping position during a movement of the head-worn computer.

2. The method of claim 1, wherein the world locked position is user modifiable.

3. The method of claim 1, further comprising presenting content in a see-through display of the head-worn computer in response to an interaction with the user interface image as indicated by a structured light disruption.

4. The method of claim 3, wherein the content is presented at a focal plane in relation to the focal plane of the surface.

5. The method of claim 4, wherein the content is presented at a focal plane that is different from the focal plane of the surface.

6. The method of claim 4, wherein the content is presented at a focal plane that is substantially the same as the focal plane of the surface.
