A head-mounted device (10), comprising: a frame (22), which has a support portion supported on the test taker's head; an imaging device (14), which obtains images of the surrounding and front environment of the test taker Image; a biometric identification system (26) to obtain biometric data about the person, a display (12) visible to the test taker, and a sound generator and detector (16,18). A processor on the frame (22) is coupled to these components and controls the content of the display (12) based on input received via the imaging device (14) and biometric system (26). The processor also monitors the sound detector (16) for detection of audio communication with respect to the sound produced by the sound generator (18) and the image obtained by the imaging device (14), and displays the test questions on the display (12) to determine Whether a person other than the test taker exists in the image obtained by the imaging device (14), or provides verbal information to the test taker. |
