Abstract

Headpiece (10) including a frame (22) having a support portion supported on a test-taker'"'"'s head, an imaging device (14) that obtains images of an environment around and in front of the test-taker, a biometric identification system (26) that obtains biometric data about the person, a display (12) viewable by the test-taker, and a sound generator and detector (16, 18). A processor on the frame (22) is coupled to these components and controls content of the display (12) based on input received via the imaging device (14) and the biometric identification system (26). The processor also monitors detection of audio communications by the sound detector (16) relative to sound generated by the sound generator (18) and images obtained by the imaging device (14) and a test is displayed on the display (12) to determine whether a person other than the test-taker is present in an image obtained by the imaging device (14) or orally providing information to the test-taker.

Claims

1. A headpiece, comprising:

a frame having a support portion adapted to be supported on a person'"'"'s head;

a housing extending from said frame;

a first imaging device arranged in connection with said housing to obtain images of an environment around and in front of the person when said support portion is supported on the person'"'"'s head;

a biometric identification system arranged in connection with said housing and configured to obtain biometric data about the person when said support portion is supported on the person'"'"'s head, said biometric identification system comprising a second imaging device arranged in a position on said housing to obtain images of at least one of iris and retina of the person when said support portion is supported on the person'"'"'s head;

a display arranged in connection with said housing and viewable by the person when said support portion is supported on the person'"'"'s head;

a sound detection interference monitoring system arranged in connection with said housing;

a memory component arranged in connection with said housing and containing a key that enables decryption of a test provided to the device with the decrypted test being displayed on said display; and

a processor arranged in connection with said frame and coupled to said first imaging device, said biometric identification system, said display, said sound interference detection system and configured to control content of said display,

said processor being further configured to monitor detection of audio communications by said sound detection interference monitoring system and images obtained by said first imaging device when said support portion is supported by the person'"'"'s head and a test is displayed on said display to determine whether a person other than the person on which said support portion is supported is present in images obtained by said first imaging device or orally providing information to the person on which said support portion is supported,

said processor being further configured to monitor biometric data obtained by said biometric identification system for changes and stop display of the test on said display when a change in biometric data obtained by said biometric identification system is indicative of the person no longer having the device supported on their head.

2. The headpiece of claim 1, wherein said housing is situated below said frame, said housing being substantially L-shaped with a first portion extending straight outward from a lateral side of said frame and second portion at an angle to said first portion and positioned in front of said frame.

3. The headpiece of claim 1, further comprising a third imaging device arranged in a position in connection with said housing in which images obtained by said third imaging device include a portion of said frame or the person'"'"'s head when said support portion is supported on the person'"'"'s head.

4. The headpiece of claim 1, further comprising an illuminator that illuminates the iris of the person in conjunction with imaging of the iris by said third imaging device.

5. The headpiece of claim 1, further comprising a connector for connecting said processor to an external electronic device.

6. The headpiece of claim 1, further comprising headphones adapted to overlie ears of the person when said support portion is supported by the person'"'"'s head.

7. The headpiece of claim 1, wherein said sound detection interference monitoring system comprises a sound generator that transmit sound waves and a sound detector that receives sound waves, said processor being configured to analyze transmitted sound waves relative to received sound waves to assess detection of sound by said sound detector.

8. The headpiece of claim 1, further comprising a chassis intrusion detection system integrated into said frame to prevent access to said processor.

9. The headpiece of claim 1, wherein said second imaging device is an iris scan camera.

10. The headpiece of claim 1, wherein said second imaging device is a retinal scan camera.

11. The headpiece of claim 1, wherein said processor is configured to control content of said display based on input received via said first imaging device and said biometric identification system.

12. The headpiece of claim 1, wherein said processor monitors biometric data obtained by said biometric identification system for changes by comparing biometric data obtained at different times to each other and considering a difference in biometric data to be indicative of more than one person providing the biometric data.

13. The headpiece of claim 1, wherein said housing is situated below said frame, said housing having a first portion extending straight outward from a lateral side of said frame and second portion at an angle to said first portion and positioned in front of said frame, the headpiece further comprising:

a third imaging device arranged on an inward facing side of said first portion of said housing whereby images obtained by said third imaging device include a portion of said frame and the person'"'"'s head when said support portion is supported on the person'"'"'s head;

an illuminator configured to provide illumination in a field of view of said third imaging device in conjunction with imaging by said third imaging device.

14. The headpiece of claim 13, wherein said sound detection interference monitoring system is arranged on said second portion of said housing and comprises a sound generator that transmit sound waves and a sound detector that receives sound waves, said processor being configured to analyze transmitted sound waves relative to received sound waves to assess detection of sound by said sound detector.

15. The headpiece of claim 2, wherein said display is arranged at a terminal end of said second portion of said housing.

16. The headpiece of claim 2, further comprising a third imaging device arranged on an inward facing side of said first portion of said housing whereby images obtained by said third imaging device include a portion of said frame and the person'"'"'s head when said support portion is supported on the person'"'"'s head.

17. The headpiece of claim 2, wherein said second portion of said housing is substantially perpendicular to said first portion of said housing.

18. The headpiece of claim 2, wherein said first imaging device and said a sound detection interference monitoring system are arranged on said second portion of said housing.

19. The headpiece of claim 4, wherein said illuminator is arranged on said housing.

20. The headpiece of claim 4, wherein said housing is situated below said frame, said housing being substantially L-shaped with a first portion extending straight outward from a lateral side of said frame and second portion at an angle to said first portion and positioned in front of said frame, said second imaging device and said illuminator being arranged on said second portion of said housing.
