Abstract
A method of access control in an electronic device includes monitoring for input at the electronic device, for each input determined to be one of a plurality of predefined gestures including gestures from a touch-sensitive input device or from a movement sensor, mapping the input to a respective Unicode character and adding the respective Unicode character to a passcode to provide an entered passcode, comparing the entered passcode to a stored passcode, and changing an access state at the electronic device if the entered passcode matches the stored passcode.
