<p>The purpose of this invention is to provide an authentication device, electronic device, method and program capable of providing appropriate guidance information to a user. This authentication device is provided with: an imaging unit for capturing images that contain the 3D glasses worn by the user; an angle detection unit for detecting the angle of a display unit; a sensor for acquiring biometric information about a part of the user's body; a position calculation unit for calculating, on the basis of the position and size of the 3D glasses contained in the image and the angle of the display unit, the relative position between the imaging unit and the 3D glasses; and a display control unit which, on the basis of the relative position, displays on the display unit a guidance image used in displaying guidance virtual images seen by the user through the 3D glasses in a position that serves as a reference when the user is positioning a body part relative to the sensor.</p> |
