Abstract

Aspects of the present invention relate presentation of digital content, in a see-through display, representing a known location in an environment proximate to a head worn computer.

Claims

1. A method of presenting an indication of another person'"'"'s (“

other person”

) known location to a person wearing a see-through display of a head-worn computer (“

first person”

), comprising;

Receiving geo-spatial coordinates corresponding to the other person'"'"'s location;

Receiving geo-spatial coordinates corresponding to the first person'"'"'s location;

Receiving a compass heading for the first person that is indicative of a direction in which the first person is looking;

Generating a virtual target line between a see-through visual plane of the head-worn computer and other person such that the target line describes a distance and angle between the other person'"'"'s location and the first person'"'"'s location; and

Presenting, in a field of view of the head-worn computer, digital content to augment the first person'"'"'s view of an environment through the see-through display of the head-worn computer, wherein the digital content is positioned within the field of view along the virtual target line such that the first person perceives the digital content in a position within the environment that represents the other person'"'"'s known location.

2. The method of claim 1 wherein the geo-spatial coordinates corresponding to the other person'"'"'s location and the first person'"'"'s location include altitude, longitude, and latitude.

3. The method of claim 1 wherein the compass heading for the first person is an based on an electronic compass in the head-worn computer.

4. The method of claim 1, wherein the compass heading for the first person is based on images of the environment captured by a camera in the head-worn computer.

5. The method of claim 1, wherein the geo-spatial coordinates corresponding to the other person'"'"'s location indicates that the other person is behind an object that obstructs the first person'"'"'s view of the other person;

and wherein the digital content indicates that a clear view is not available.

6. The method of claim 1, wherein a remote server is used to generate the target line.

7. The method of claim 1, wherein the target line is generated local to the head-worn computer.
