Abstract
A computer implemented method for detecting input gesture events on a touchscreen of an electronic device and for unlocking the electronic device is disclosed. The method may include displaying, while the electronic device is in a locked state, a plurality of guidance lines on the touchscreen of the electronic device, detecting, during an input gesture event, guidance line crossings and calculating a number of guidance line crossings detected during the input gesture event. The method may also include converting a calculated number of detected guidance line crossings into at least one password digit, comparing a sequence of password digits to a stored password in the electronic device and unlocking, in response to comparing the sequence of password digits to the stored password, the electronic device.
