20110002510OPERATOR INTERFACE FOR FACE AND IRIS RECOGNITION DEVICES - A primarily hand-held or adjustable-mount iris recognition device wherein feedback to the operator is provided by visible illumination or imagery projected onto the face of the subject, as well as an audio signal, while infra-red illumination is projected onto the face of the subject as an illumination source for an iris recognition process. When the device is pointed in the direction of the subject, the infra-red illumination is directed to illuminate primarily the eye region whereas the visible illumination is directed to illuminate primarily other regions including the cheeks. The visible illumination is configured such that the position of the visible illumination on the face indicates to the operator whether the iris recognition device is pointed in the correct direction and at the correct distance for optimal iris recognition. The brightness of the visible illumination is modified in response to the result of an eye detection process performed on the iris recognition device, and the brightness, color and other attributes of the visible illumination or the audio signal are modified in response to the result of eye-finding or other process, including the results of an iris recognition process.01-06-2011
