Abstract: A communication or computing device having a touchscreen interface is adapted to detect a duress condition upon user access through input of a gesture-based password or authentication code. One or more force sensors are provided for detection of force applied at the touchscreen surface, and interoperate with processing elements to detect input of a gesture-based password through contact at the touchscreen interface; determine that force detected by at least one of the force sensors during input of the password exceeds a predefined threshold; and compares the input password with previously stored information to determine that the input password substantially corresponds to the previously stored information. If the input password substantially corresponds to the previously stored information and the detected pressure exceeds the threshold, a duress condition is determined for the device.

Abstract: A handheld communication or computing device having a touchscreen interface is configured to permit access in response to detection of a pressure-based password by a plurality of force sensors, each one of the force sensors corresponding to one of a plurality of sensing regions defined on the surface of the touchscreen interface. Upon detecting a sequence of presses applied to a plurality of the force sensors, the detected sequence is compared to previously stored information to determine if it matches. If there is a match, access to functions and/or data at the device is granted.
