Abstract

A personal display system having an ocular scan unit for generating user identification information and an interface for conveying user identification to a connected system.

Claims

1. A personal display system, comprising:

a headset;

a transparent optical display surface carried on said headset; and

an ocular scan unit comprising;

an imager for imaging an attribute of a user'"'"'s eye and generating an output signal;

an identification information generator for generating identification data that identifies a user in response to said output signal from said imager; and

logic responsive to the identification data of the identification information generator for displaying user-dependent information on the display surface, the displayed user-dependent information being viewable on the display surface as overlayed with objects viewable by the user though the display surface.

2. The personal display system of claim 1, wherein said ocular scan unit further comprises:

an optical system for focusing light reflected from said user'"'"'s eye onto said imager.

3. The personal display system of claim 2 wherein said optical system comprises a beam splitter for reflecting light from said user'"'"'s eye to said imager.

4. The personal display system of claim 2 wherein said optical system comprises a lens for focusing light onto said imager.

5. The personal display system of claim 2 wherein said display surface comprises a light emitting diode.

6. The personal display system of claim 5 wherein said display surface further comprises said imager.

7. The personal display system of claim 6 wherein said imager comprises active pixels.

8. The personal display system of claim 2 wherein said display surface comprises a liquid crystal display.

9. The personal display system of claim 2 wherein said display surface comprises an optical lens.

10. The personal display system of claim 2 further comprising a projector for projecting imagery onto said display surface.

11. The personal display system of claim 1 further comprising an interface unit for exchanging data with a connected system via a wireless communication link.

12. The personal display system of claim 11 wherein said connected system comprises a real world simulation device.

13. The personal display system of claim 3 wherein said connected system comprises a security access clearance device.

14. The personal display system of claim 3 wherein said display surface comprises a surface of an optical lens, wherein the logic for projecting comprises an image projector configured to project imagery onto the display surface, wherein content of the imagery is generated by the connected system and is communicated to the personal display system via the wireless communication link, and wherein content of the imagery is responsive to the ocular scan unit.

15. A method of providing identification-dependent data to a user comprising:

reflecting light from a user'"'"'s eye;

generating a scan signal in response to light reflected from said eye;

evaluating the scan signal to identify the user; and

displaying to the user information that is dependent upon the identified user, wherein the information is displayed to the user on a transparent display surface as overlayed with objects viewable by the user through the display surface.

16. The method of claim 15, further comprising transmitting identification data to a connected system.

17. A personal display system, comprising:

a headset having a transparent optical display surface to be located in front of a user'"'"'s eyes when the headset is positioned on the user'"'"'s head;

means for displaying visual information to a user on the optical display surface;

means for supporting said means for displaying in relation to the user;

means for scanning of said user'"'"'s eye and generating a scan image;

means responsive to the means for scanning for evaluating the scan image to identify the user; and

means responsive to the means for evaluating to generate user-dependent display information for displaying on the optical display surface as overlayed with objects viewable by the user through the display surface.

18. A personal display system according to claim 17 wherein said means for displaying comprises a liquid crystal display.

19. A personal display system according to claim 17 wherein said means for scanning said user'"'"'s eye comprises active pixels comprised on organic light emitting diodes.
