Abstract: A computer-implemented method of authenticating a user with a computing device is disclosed. The method involves displaying a grid of selectable visually-distinguishable graphical elements on a device display, receiving from a user of the device a drawn pattern across the selectable graphical elements, comparing the received drawn pattern to information representing a stored authentication pattern for the user, and unlocking access to functions on the device if the received drawn pattern substantially matches the stored authentication pattern.

Abstract: A computer-implemented touch screen call interface includes announcing an incoming telephone call on a mobile device touch screen display, connecting to the call and displaying a slidable panel on the display while locking the display from inputs other than unlocking inputs, receiving a user selection moving the slidable panel away from a position that covers one or more selectable controls, and unlocking the display for selection of the selectable controls while the slidable panel stays in a position that leaves the selectable controls uncovered.
