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 rel

대표청구항 ▼

1. An eye-imaging system for a head-worn computer with a see-through display, comprising: a camera positioned in the head-worn computer with the see-through display, wherein the camera is further positioned to capture an image of an eye of a user wearing the head-worn computer;an IR light source positioned in the head-worn computer such that it irradiates the eye of the user with IR light;a hot mirror comprising a partially reflective partially transmissive surface adapted to reflect IR light and transmit visible light positioned in the head-worn computer such that image content light is transmitted through the hot mirror to the eye of the user and IR light reflected from the eye of the user is reflected by the hot mirror towards the camera; andthe camera adapted to capture the IR light as the reflections from the eye of the user. 2. The eye-imaging system of claim 1, wherein the head-worn computer includes a display adapted to generate the image content light. 3. The eye-imaging system of claim 2, wherein the display is a reflective display and the hot mirror is positioned to reflect illumination light towards the reflective display and then transmit the image content light through the hot mirror. 4. The eye-imaging system of claim 3, wherein the reflective display is a liquid crystal on silicon (“LCoS”) display. 5. The eye-imaging system of claim 4, wherein substantially all of the illumination light is incident the reflective surface between 45 degrees and 135 degrees relative to a front surface of the reflective display. 6. The eye-imaging system of claim 3, wherein the reflective display is a digital light processor (“DLP”). 7. The eye-imaging system of claim 6, wherein the illumination light is generated at a position adjacent to the reflective display. 8. The eye-imaging system of claim 6, further comprising a dark-light trap positioned to capture off-pixel light. 9. The eye-imaging system of claim 2, wherein the display is an emissive display.
