Methods and apparatus for directing the gaze of a user in an iris recognition system

An iris biometric acquisition system comprising:

• a mirror to reflect an image of an eye of a user towards the user;
• a visibility limiting device comprising at least one of a privacy film or a plurality of louvers, disposed between the user and the mirror to limit an angular field of view of the mirror;
• and
• an image sensor to acquire an image of the iris of the user when the iris is within the angular field of view of the mirror.

A method for directing a gaze of a user to one of different locations or positions of an iris biometric acquisition system for accommodating different heights of individuals, the method comprising:

• limiting, by a visibility limiting device positioned between a user attention device and a user, an angular field of view of the user attention device;
• providing, by the visibility limiting device and the user attention device, guidance to the user to position an iris of the user in accordance with the limited angular field of view;
• and
• acquiring, by a sensor positioned adjacent to the visibility limiting device, imagery of the iris positioned in accordance with the guidance provided by the visibility limiting device and the user attention device.
