Abstract: In a fingerprint sensing system, a determination is made of a center of attention, COA, point. The COA point is a point on a finger of a user that is likely to be in proximity of the center of a fingerprint image of the finger obtained by a fingerprint sensor. This COA determination is used in guiding the user in a fingerprint enrolment procedure.
