Multi-finger sliding detection using fingerprints to generate different events
First Claim
1. A method, comprising:
- detecting, by a microprocessor, a first touch and a simultaneous second touch on an electronic device;
determining, by the microprocessor, a first finger with which the first touch is associated and a second finger with which the second touch is associated;
detecting, by the microprocessor, a pattern of motion of the first touch and the second touch;
determining, by the microprocessor and based on the detected pattern of motion, whether the detected pattern of motion corresponding to the first touch and the second touch is not physically achievable with fingers of a same hand; and
allowing or denying, by the microprocessor, a function of the electronic device based on the determining whether the detected pattern of motion corresponding to the first touch and the second touch is not physically achievable with fingers of the same hand.

Abstract
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.

11. An electronic device, comprising:
-
a sensing device; and a microprocessor coupled to the sensing device, said microprocessor programmed to; detect a first touch from the sensing device; determine a first finger with which the first touch is associated; detect a second touch from the sensing device; determine a second finger with which the second touch is associated; detect a pattern of motion of the first touch and the second touch; correlate the detected pattern of motion to an action for controlling the electronic device; and determine, based on the detected pattern of motion, whether the detected pattern of motion corresponding to the first touch and the second touch is not physically achievable with fingers of a same hand. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A method, comprising:
-
detecting, by a microprocessor, a first touch placed on an input device of an electronic device and a second touch placed on the input device; determining, by the microprocessor, a first finger with which the first touch is associated and a second finger with which the second touch is associated; detecting, by the microprocessor, a pattern of motion of the first touch and the second touch; determining, by the microprocessor and based on the detected pattern of motion, whether the detected pattern of motion corresponding to the first touch and the second touch is not physically achievable with fingers of a common hand; triggering, by the microprocessor, an action using the finger determination and based on the determination of whether the detected pattern of motion is not physically achievable; and triggering a different action if the detected pattern of motion is physically achievable.
