EXTERNAL USER INTERFACE FOR HEAD WORN COMPUTING
Head worn computers may include two physically separated cameras mounted on a front surface that capture movements of a finger of the user of the head-worn computer. The head worn computer includes an image source adapted to display content in a see-through display of the head-worn computer, wherein the content is positioned to be perceived by a user as positioned on a surface proximate the head-worn computer. A processor of the head worn computer is adapted to develop a 3D model, based on the captured finger movements and the position of the content, describing an interaction of the finger with the content.
1 . A head-worn computer, comprising:
two physically separated cameras mounted on a front surface of the head-worn computer, wherein the two physically separated cameras capture movements of a finger of the user of the head-worn computer;
an image source adapted to display content in a see-through display of the head-worn computer, wherein the content is positioned to be perceived by a user as positioned on a surface proximate the head-worn computer; and
a processor adapted to develop a 3 D model, based on the captured finger movements and the position of the content, describing an interaction of the finger with the content.
2 . The head-worn computer of claim 1 , wherein the interaction is a gesture.
3 . The head-worn computer of claim 1 , wherein the content is a user interface adapted to control an aspect of the head-worn computer.
4 . The head-worn computer of claim 3 , wherein the interaction is an interaction with a control portion of the user interface.
