EYE IMAGING IN HEAD WORN COMPUTING
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.
1 . A head-worn computer, comprising:
a. A camera adapted to capture a reflected image of a eye of a person wearing the head-worn computer, wherein the camera is positioned to capture the reflected images of the eye from an optical path that is in-line with an image-light path through delivery optics that are adapted to present an image to the eye;
b. A processor adapted to present advertisement content in a display of the head-worn computer; and
c. The processor further adapted to:
i. cause the camera to capture a plurality of reflected images of the eye during the presentation of the advertisement content;
ii. calculate a persistence statistic indicative of how long the person's eye was aligned with the advertisement content based on the plurality of captured reflected images; and
iii. communicate the persistence statistic to a advertisement assessment system.
2 . The head-worn computer of claim 1 , wherein the persistence statistic is used as a conversion indication.
3 . The head-worn computer of claim 1 , wherein the processor interacts with a server to calculate the persistence statistic.
4 . The head-worn computer of claim 1 , wherein the processor transmits the reflective image of the eye to a server for the verification.
5 . The head-worn computer of claim 1 , wherein the camera is located proximate an image display system, wherein the image display projects image light along the optical path in-line with the delivery optics adapted to present an image to the eye.
6 . The head-worn computer of claim 5 , wherein the image display is a reflective display and the reflected image of the eye of the person reflects off of the image display prior to being captured by the camera.
7 . The head-worn computer of claim 5 , further comprising a reflective surface positioned between the image display and the camera, wherein the camera captures the reflected image of the eye of the person after it reflects off of the reflective surface.
8 . The head-worn computer of claim 7 , wherein the image display is a front lit reflective image display.
9 . The head-worn computer of claim 7 , wherein the image display is an emissive display.
