Abstract

Aspects of the present invention relate to methods and systems for imaging, recognizing, and tracking of a user'"'"'s eye that is wearing a HWC. Aspects further relate to the processing of images reflected from the user'"'"'s eye and controlling displayed content in accordance therewith.

Claims

1. A method, comprising:

a. Receiving, at a camera internal to a head-worn computer, at least a portion of a reflected image of an eye of a person wearing the head-worn computer, wherein the image of the eye is reflected off of a no-power state mirror of a DLP reflective display.
