Abstract: Headpiece includes a frame having a support portion adapted to be supported on a person's head and a viewable portion adapted to present visual data to the person when said support portion is supported on the person's head. A camera obtains images of an environment around the person. A user interface receives input from the person. A processor controls content of the viewable portion based on input received via the user interface. A communication-detecting sensor detects communications. The processor monitors detection of communications detected by the communication-detecting sensor and images obtained by the imaging device when the viewable portion is displaying a test to determine whether a person other than the person on which the support portion is supported is present or providing information to the person on which the support portion is supported.
