Abstract

Aspects of the present invention relate to methods and systems for presenting digital content in a field of view of a head-worn computer.

Claims

1. A method, comprising:

a. Capturing more than one image of an object in an environment proximate a person wearing a head-worn display;

b. Identifying that the object is moving in the environment by comparing the object'"'"'s position in the more than one image; and

c. Removing the object from consideration as a distance marker when presenting content in the head-worn display, wherein the content is presented at a focal plane at a distance from the head-worn display.

2. The method of claim 1, wherein the step of capturing the image is accomplished through the use of a camera mounted proximate the head-worn see-through display.

3. The method of claim 1, further comprising identifying the object as a known object.

4. The method of claim 3, wherein the step of presenting involves making a distance determination by assessing a size of the object as captured with the known object'"'"'s size attributes.

5. The method of claim 4, wherein the distance determination involves assessing a size of the object as captured with the known object'"'"'s size attributes.

6. The method of claim 1, wherein the step of presenting involves generating an image with a front lit reflective display.

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

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

9. The method of claim 6, wherein the head-worn display further comprises an in-optic eye imaging system.
