Multi-finger sliding detection using fingerprints to generate different events
Fingerprint portions of two or more different fingers are detected on a detection surface, such as an optical surface, a touch pad, a touchscreen, or the like, and then a further detection made that the person has moved their finger(s), for example, apart, together or relative to one another. The movement can be detected based on identifying the fingerprint portion sliding across the screen. The combination of fingerprint information associated with a corresponding motion is correlatable to one or more actions or triggering events that are used to control one or more electronic devices. Further aspects are directed toward utilizing one or more of the techniques herein for a security application. For example, two users, each placing one or more fingers on a touch screen or touch pad, with the fingerprints thereafter being recognized, perform a certain movement with this triggering the unlocking, or locking, of an object.
