Abstract

Aspects of the present invention relate to user interface control of a head-worn computer.

Claims

1. A method of presenting a virtual user interface, comprising:

a. Determining a head pose of a user wearing a head-worn computer based on sensor feedback of a sensor system in the head-worn computer;

b. Determining that the head pose is within a predetermined range; and

c. Presenting the virtual user interface such that it appears, from the user'"'"'s perspective, on a surface proximate the user.

2. The method of claim 1, wherein the virtual user interface is presented by projecting an image on the surface with a projector.

3. The method of claim 1, wherein the virtual user interface is presented as augmented reality content in a see-through display of the head-worn computer.

4. The method of claim 1 further comprising:

repeatedly determining the head pose of the user and only presenting the virtual user interface when the head pose is within the predetermined range.

5. The method of claim 1, wherein the predetermined range is indicative of the user looking in a direction of the surface where the virtual user interface is presented.

6. The method of claim 1, wherein the direction is downward.

7. The method of claim 2, further comprising projecting a pattern of structured light overlapping the virtual user interface and monitoring the pattern for disruptions to be characterized as an interaction with the virtual user interface.

8. The method of claim 7 wherein the virtual user interface and structured light maintain their shape and overlapping position during a movement of the head-worn computer.
