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, comprising:

tracking a path of a first person as the first person moves through an environment, wherein the tracking is through a first processor receiving global positioning system (GPS) data indicative of the first person'"'"'s location in a first navigation facility of a computer device proximate the first person and involves both tracking the path and tracking event notifications provided by the first person; and

presenting an indication of the path of the first person to a see-through head-worn computer display of a second person when the second person is proximate the path as determined by a second processor receiving GPS data indicative of the second person'"'"'s location in a second navigation facility of the see-through head-worn computer display, wherein the presenting includes presenting a visual indication of the path and event notifications on a pre-stored mapped instance in the see-through head-worn computer display of the second person, wherein the second processor is adapted to identify that the first person is obstructed from view by the second person by identifying at least one obstacle on the pre-stored mapped instance that interferes with the second person'"'"'s view of the first person'"'"'s known-location, wherein the identification of the obstructed view presented on the pre-stored mapped instance is determined based on a comparison of the GPS location of the first person and the GPS location of the second person in relation to the obstacle on the pre-stored mapped instance.

2. The method of claim 1, wherein the event notification is an indication that an area has been searched as indicated on the pre-stored mapped instance.

3. The method of claim 1, wherein the step of presenting includes presenting an augmented reality view of the path and event notification on the pre-stored mapped instance.

4. The method of claim 1, wherein the path is maintained at a remote location and indications of the path are transmitted to any one of a plurality of pre-designated computing devices that become proximate the path.

5. The method of claim 1, wherein the event notification presentation includes an indication that the location of the event notification is in an obstructed location.

6. The method of claim 1, wherein the step of presentation further includes presenting navigation information to indicate to the see-through head-worn computer display of the second person where the path is located.
