Eye imaging in head worn computing
Head-worn computers with eye-imaging systems include a camera system positioned in a head-worn computer, wherein the camera system is further positioned to capture eye-image light that originates as reflections from a user's eye, wherein the camera system is further positioned to capture eye-image light as a reflection from a partially reflective surface that is positioned in front of an image display in the head-worn computer, wherein image light, from the image display, is transmitted through the partially reflective surface. A processor is adapted to cause the camera system to capture the eye-image light. The processor is further adapted to cause a comparison of the captured eye-image light with a pre-stored eye image of a known user of the head-worn computer. In the event the comparison confirms the identity of the known user, the user is granted permission to view content to be presented in a display of the head-worn computer.
1. A head-worn computer with an eye-imaging system, comprising:
a camera system positioned in a head-worn computer, wherein the camera system is further positioned to capture eye-image light that originates as reflections from an eye of a user, wherein the camera system is further positioned to capture the eye-image light as a reflection from a partially reflective surface that is positioned in front of an image display in the head-worn computer, wherein image light, from the image display, is transmitted through the partially reflective surface; and
a processor adapted to cause the camera system to capture the eye-image light,
wherein the processor is further adapted to cause a comparison of the captured eye-image light with a pre-stored eye image of a known user of the head-worn computer, and
wherein, in the event the comparison confirms the identity of the known user, the user is granted permission to view content to be presented in a display of the head-worn computer.
2. The head-worn computer of claim 1 , wherein the camera system is further positioned to capture the eye-image light originating on an optical path that is in-line with a content presentation optical path.
3. The head-worn computer of claim 1 , wherein the camera system is further positioned to capture the eye-image light originating on an optical path that is outside of a content presentation optical path.
4. The head-worn computer of claim 1 , wherein the processor is further adapted to detect when the head-worn computer is mounted on the user's head by detecting an arm pressure.
5. The head-worn computer of claim 1 , wherein the processor is further adapted to detect when the head-worn computer is mounted on the user's head by detecting when the head-worn computer is turned on.
6. The head-worn computer of claim 1 , wherein the processor is further adapted to detect when the head-worn computer is mounted on the user's head by detecting an arm position.
7. The head-worn computer of claim 1 , wherein the processor is further adapted to detect when the head-worn computer is dismounted from the user's head, wherein, the indication of dismounting causes a security system to remove the permission until the user's identity is re-confirmed.
8. The head-worn computer of claim 7 , wherein the processor is further adapted to detect when the head-worn computer is dismounted by detecting an arm pressure.
9. The head-worn computer of claim 7 , wherein the processor is further adapted to detect when the head-worn computer is dismounted by detecting when the head-worn computer is turned on.
10. The head-worn computer of claim 7 , wherein the processor is further adapted to detect when the head-worn computer is dismounted by detecting an arm position.
11. The head-worn computer of claim 1 , wherein the processor is further adapted to capture the eye-image light periodically while the head-worn computer is being worn such that a health parameter of the user is determined.
12. The head-worn computer of claim 1 , wherein the processor is further adapted to capture the eye-image light at times based on a predicted activity of the user.
