Abstract
This document relates to user-authentication gestures. One example can capture multiple biometric features when a user-authentication gesture is performed as a device authentication attempt. The example can compare values of the multiple biometric features to previous values stored for the user. The example can further unlock the computing device in an instance where the values of the multiple biometric features satisfy a similarity threshold relative to the previous values.
Claims21
1-20. (canceled)
A device comprising:
- a touch screen having one or more touch sensors configured to sense touch contact pressure on the touch screen;
- at least one hardware processor;
- and
- at least one computer-readable storage medium having computer-executable instructions that, when executed by the at least one hardware processor, cause the at least one hardware processor to:
- obtain, from the one or more touch sensors, a touch contact pressure of a touch contact received from a user of the device;
- perform a comparison of the received touch contact pressure to one or more stored touch contact pressure gesture recognition values;
- and
- based at least on the comparison, determine whether the user has performed a gesture on the touch screen using the touch contact.
A device comprising:
- a touch screen having one or more touch sensors configured to sense touch contacts on the touch screen;
- at least one hardware processor;
- and
- at least one computer-readable storage medium having computer-executable instructions that, when executed by the at least one hardware processor, cause the at least one hardware processor to:
- determine, using the one or more touch sensors, a first touch contact duration of a first touch contact and a second touch contact duration of a second touch contact received from a user of the device, the first touch contact being received for at least some time concurrently with the second touch contact;
- perform comparisons of the first touch contact duration and the second touch contact duration to one or more stored touch contact duration gesture recognition values;
- and
- based at least on the comparisons, determine whether the user has performed a gesture on the touch screen using the first touch contact and the second touch contact.
A method for gesture recognition on a touch screen device, the method comprising:
- determining at least one of a touch contact pressure or a touch contact duration of a touch contact received by the touch screen device from a user;
- performing one or more comparisons of the touch contact pressure or the touch contact duration to one or more stored authentication gesture recognition values of an authentication gesture;
- based at least on the one or more comparisons, determining whether the user has properly performed the authentication gesture;
- and
- when the user has properly performed the authentication gesture, authenticating the user on the touch screen device.
