Abstract

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

Claims

1. A head-worn computer, comprising:

a. Two physically separated cameras mounted on a front surface of the head-worn computer;

b. A laser projector mounted on the front surface of the head-worn computer adapted to project a user interface onto a surface proximate the head-worn computer;

c. Wherein the two physically separated camera'"'"'s simultaneously capture movements of a finger of the user in relation to the user interface on the surface; and

d. A processor adapted to develop a 3D model of interactions with the user interface from the captured movements of the finger.

2. A head-worn computer, comprising:

a. Two physically separated cameras mounted on a front surface of the head-worn computer;

b. An image source adapted to display a user interface as content in a see-through display of the head-worn computer, wherein the user interface is positioned to be perceived by a user as positioned on a surface proximate the head-worn computer;

c. Wherein the two physically separated camera'"'"'s simultaneously capture movements of a finger of the user; and

d. A processor adapted to develop a 3D model of interactions of the finger with the content displayed user interface from the captured movements of the finger.
