Abstract: In a conventional apparatus for displaying interviewee information on a portable information terminal held by a user, when the user actually faces an interviewee, it is not possible to quickly acquire information relating to the interviewee at timing immediately before an interview, and such information have been acquired after start of the interview. For this reason, there have been awkward situations where the user and the interviewee cannot be on the same topic at the start of the interview. A portable information terminal according to a representative embodiment of the present invention determines whether or not a person in the vicinity of a user is a potential interviewee by performing behavior analysis on such a person, and when it is determined that the person is a potential interviewee, acquires information relating to the person to present it to the user. Consequently, the user is allowed to previously be aware of the information relating to the interviewee before the start of the interview or at timing at which the person is recognized as an interviewee.

Abstract: In a cooperative display system that connects a portable terminal and a head mounted display to display information in cooperation, the portable terminal displays information on a first display, and transmits at least a part of the information that is displayed to the head mounted display, and the head mounted display shares and displays the information transmitted from the portable terminal on a second display. Here, the information displayed on the portable terminal is hierarchical information, and the information displayed on the head mounted display is lower-level information in the hierarchical information. In addition, whether a user is stationary or moving is detected by a sensor of the portable terminal, and in a case where the user is stationary, the display of the information on the portable terminal is stopped, and the information is displayed only on the head mounted display.

Abstract: A user authentication system includes a main body device and an authentication device. The main body device has an authentication code transmission requesting unit, a verification unit, and an unlocking unit. The authentication code transmission requesting unit generates an authentication code transmission request including a first value, and transmits the authentication code transmission request to the authentication device. The authentication device generates an authentication code in response to the first value in the authentication code transmission request, and transmits the authentication code to the main body device. The verification unit determines that authentication is successful if the authentication code is received from the authentication device. When the verification unit determines that the authentication is successful, the unlocking unit enables a predetermined functionality.
