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 an image of an object in an environment proximate a person wearing a head-worn display;

b. recognizing the object as a known object with known physical dimensions;

c. analyzing the image of the object in relation to the known physical dimensions to determine an approximate distance between an image capture device used to capture the image of the object and the object; and

d. displaying content in the head-worn display at a focal plane relative to the approximate distance.

2. The method of claim 1, wherein the focal plane is defined by a convergence plane.

3. The method of claim 1, wherein the focal plane is defined by a perspective viewing angle.

4. The method of claim 1, wherein the focal plane is defined by a size relative to the object.

5. The method of claim 1, wherein the focal plane is defined by a distance at which the content comes into focus for a person wearing the head-worn display.

6. The method of claim 1, wherein the image capture device is mounted proximate the head-worn display.

7. The method of claim 1, wherein the known object is an object with a standard physical size.

8. The method of claim 1, wherein the known object is at least one of a doorway, a mailbox, a window, a window frame, a house siding, a brick, a light switch, a light post, a telephone poll, a road sign, a speed limit sign, a reflector, a road reflector, a vehicle, a building, a tile, a head size, and an inter-pupil distance.
