Spatial location presentation in head worn computing

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.

We claim: 
     
         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.
