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:

a. Receiving a geo-spatial position of first and second persons, both of which wearing head-worn computers with see-through displays;

b. Presenting content in the first person'"'"'s see-through display content indicative of the second person'"'"'s location, wherein the content is aligned with a virtual target line that connects the first person and second person; and

c. Maintaining the virtual target line and content position until receiving an indication that the second person has moved, wherein the indication of the move is based on a motion sensor in the second person'"'"'s head-worn computer, wherein the motion sensor communicates motion data to a remote service.

2. The method of claim 1, wherein the virtual target line is calculated remotely and communicated to the first person'"'"'s head-worn computer.

3. The method of claim 1, wherein the virtual target line is calculated at the first person'"'"'s head-worn computer.

4. The method of claim 1, wherein the motion data is communicated in a peer-to-peer network to the first person'"'"'s head-worn computer.

5. The method of claim 1, wherein the motion data is communicated to a central server.

6. The method of claim 1, wherein the motion sensor is an IMU and is activated for the method when GPS data is unavailable.

7. The method of claim 1, wherein each of the head-worn computers includes an IMU, GPS sensor, wireless communication system and an in-line eye imaging system.

8. The method of claim 7, wherein the eye imaging system provides for user verification and secure communications.
