Biometric identification headpiece system for test taking
First Claim
1. A headpiece, comprising:
- a frame having support structure for supporting said frame on a head of a person and a viewing portion configured to be in front of a face of the person when said frame is supported on the head of a person;
at least one light valve assembly arranged in said viewing portion and having a first state in which the person is able to view an object in front of the headpiece through said at least one light valve assembly when said frame is supported on the of a person and an alternative second state in which viewing of the object in front of the headpiece through said at least one light valve assembly by the person on whose head said frame is supported is prevented;
a biometric identification system arranged on said frame and that periodically attempts to obtain biometric data about the person when said frame is supported on the head of a person; and
a processor coupled to said at least one light valve assembly and said biometric identification system and that controls whether said at least one light valve assembly is in the first state or the second state,said processor analyzing biometric data obtained by said biometric identification system relative to previously obtained biometric data associated with the person on whose head said frame is supported and when the analysis by said processor indicates that the biometric data obtained by said biometric identification system does not match the previously obtained biometric data associated with the person on whose head said frame is supported, said processor controlling said at least one light valve assembly to change from the first state to the second state and prevent viewing of the object in front of the headpiece,said processor further controlling said at least one light valve assembly to change from the first state to the second state and prevent viewing of the object in front of the headpiece when said biometric identification system does not obtain biometric data after said biometric identification system has previously obtained biometric data while said frame is supported on the head of a person.

Abstract
Headpiece for test-taking includes a frame having support structure for supporting the frame on a person'"'"'s head and a viewing portion configured to be in front of the person'"'"'s face when the frame is supported on the person'"'"'s head, and at least one light valve assembly arranged in the viewing portion. Each light valve assembly has a first state in which the person is able to see therethrough and an alternative second state in which viewing therethrough is prevented. A controller controls whether the light valve assembly is in the first state or the second state to thereby control viewing therethrough. The light valve assembly may be situated rearward of part of the viewing portion. Only the headpiece wearer is thus able to view test questions on a display through the light valve assembly.

8. An arrangement for test-taking, comprising:
-
a headpiece comprising a frame having support structure for supporting said frame on a head of a person, a viewing portion coupled to said frame and configured to be in front of a face of the person when said frame is supported on the head of a person, and at least one light valve assembly arranged in said viewing portion; a display configured to display a test in the form of a series of questions to the person when said frame is supported on the head of a person and when said display is in front of said headpiece, each of said at least one light valve assembly having a first state in which the person is able to view said display through said at least one light valve assembly when said frame is supported on the head of a person and an alternative second state in which viewing of said display through said at least one light valve assembly by the person on whose head said frame is supported is prevented; at least one user interface configured to receive input from the person when said frame is supported on the head of a person relating to the questions displayed on said display; and a processor arranged on said frame and coupled to said at least one user interface, said display and said at least one light valve assembly, said processor being configured to control content of said display based on input received via said at least one user interface to change content of said display as a response to the input received via said at least one user interface, said processor being further configured to control said at least one light valve assembly to be in the first state or the second state based on content being displayed on said display such that while a first portion of content is being displayed on said display, said at least one light valve assembly is in the first state and while a second portion of content is being displayed on said display, said at least one light valve assembly is in the second state. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A method for test-taking, comprising:
providing each of a plurality of persons with a device, each device including a headpiece comprising a frame having support structure for supporting the frame on a head of the person, a viewing portion configured to be in front of the a face of the person when the frame is supported on the head of the person, and at least one light valve assembly arranged in the viewing portion and having a first state in which the person is able to view an object in front of the headpiece through the at least one light valve assembly when the frame is supported on the head of the person and an alternative second state in which viewing of the object in front of the headpiece through the at least one light valve assembly by the person on whose head the frame is supported is prevented; displaying on at least one display, test questions; enabling each person to provide answers to the test questions being displayed on the at least one display using at least one respective user interface; controlling, using a processor, content of the at least one display based on input received via the at least one respective user interface; and independently controlling the at least one light valve assembly of each of the headpieces to be in the first state or the second state and content of the at least one display dependent on one another to thereby control viewing of content of the at least one display through the at least one light valve assembly of each of the headpieces such that each person is able to view only specific ones of the test questions in an order different from each other person. - View Dependent Claims (21, 22)
