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 head-worn display apparatus adapted to present an indication of another person'"'"'s (“

other person”

)-known location with respect to a user wearing the head-worn display apparatus, comprising;

a. a see-through electronic display adapted to display digital content and providing a see-through view for the user; and

b. a processor receiving data indicative of the other person'"'"'s known location and in communication with the see-through electronic display, the processor adapted to generate a virtual target line indicative of a distance and angle between the see-through display and the other person and to cause digital content to be displayed along the virtual target line on the see-through display,

wherein the processor is adapted to identify that the other person is obstructed from view by identifying at least one actual obstacle in the field of view that interferes with the user'"'"'s view of the other person'"'"'s known location,

wherein the processor is adapted to generate, in the field of view, digital content in-line with the virtual target line, and

wherein the digital content is indicative of the other person'"'"'s known location and is indicative that the known location is obstructed from view by the at least one actual object.

2. The apparatus of claim 1, wherein the processor identifies the at least one actual obstacle by assessing a map of objects in an area proximate the virtual target line to identify a potential intersection of the virtual line with an object on the map.

3. The apparatus of claim 1, wherein the processor identifies the at least one actual obstacle by using a range finder to identify an actual object that is present at a shorter distance than a distance prescribed by the virtual target line.

4. The apparatus of claim 1, wherein the processor is adapted to generate digital content that is presented at a focal plane associated with a distance prescribed by the virtual line.

5. The apparatus of claim 1, wherein the digital content is indicative of a general area of where the other person is located.

6. The apparatus of claim 1, wherein the digital content is indicative of a general area of where the other person is located and indicative that the general area is relatively close to the other person.

7. The apparatus of claim 1, wherein the digital content is indicative of a general area of where the other person is located and indicative that the general area is not relatively close to the other person.
