Abstract
A method, system, and computer program product is provided that controls platen movement during a live scan. The platen moves in response to finger movement. The present invention then applies a counter force that counters the platen movement. In one embodiment, the counter force has a magnitude which is a function of the speed of the platen movement. The platen can move in a lateral direction (right or left) in response to the finger. The direction in which the counter force is applied is a direction that counters the platen movement in a determined direction. In one example, the force is applied through a motor that drives the platen in a direction opposite the direction of movement caused by the finger or fingers during the live scan. In this way, the counter force which is applied helps prevent a user from moving a finger too rapidly during the live scan. As a result, a high-quality fingerprint image can be obtained with less training and experience in live scan fingerprinting. A user need not follow complicated live scan bars or other indications of a recommended speed or rate of platen movement.
