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. Aspects further relate to determining health conditions of the user based on eye imaging technologies.
Claims9
An eye-imaging system, comprising:
- a camera system, adapted to capture eye-image light that originates as one or more reflections from an eye of a user, the camera system positioned in a head-worn computer, wherein the head-worn computer is adapted to display digital content to a user along a common optical axis that intersects with an eye of the user such that the user can see the digital content;
- a light source positioned in the head-worn computer such that it irradiates the eye of the user, along the optical axis, with a pattern of light to produce at least a portion of the reflections from the eye of the user;
- and
- a processor adapted to analyze a difference between the irradiated pattern of light and the captured eye-image light, wherein the difference is interpreted as positional changes of the eye of the user.
