Spatial location presentation in head worn computing
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.
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 global position system (“GPS”) 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 identification of the obstructed view is determined based on a comparison of a GPS location of the user and the GPS location of the other person in relation to a pre-stored mapped instance of the actual object, wherein the processor is adapted to generate, in the field of view, digital content in-line with the virtual target line, wherein the digital content comprises an indicator of the other person's known location, and wherein the indicator is modified if the known location is obstructed from view by the at least one actual object.
2. The apparatus of claim 1 , wherein the map instance is stored remotely from the head-worn display.
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.
8. The apparatus of claim 1 , wherein the indicator is modified by modifying a visual characteristic of the indicator.
9. The apparatus of claim 1 , wherein the indicator is modified by modifying an audio characteristic of the indicator.
10. The apparatus of claim 1 , wherein the map instance is stored locally on the head-worn display.
