UNLOCKING ELECTRONIC DEVICES USING TOUCHSCREEN INPUT GESTURES |
摘要 |
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. |

1. A computer program product for detecting input gesture events on a touchscreen of a smartphone and for unlocking the smartphone, the computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions configured to cause a processor to perform a method comprising:
displaying, while the smartphone is in a locked state, a plurality of guidance lines on the touchscreen of the smartphone, the plurality of guidance lines displayed in a plurality of colors; detecting, during an input gesture event, guidance line crossings, the guidance line crossings including a transition of the input gesture event from a first side of a guidance line to a second side of the guidance line; calculating a number of guidance line crossings detected during the input gesture event; converting the number of guidance line crossings into at least one password digit, the converting including multiplying the number of guidance line crossings by a numerical weighting value of 2; comparing a sequence of password digits including the at least one password digit to a password stored in the smartphone; and unlocking, in response to comparing the sequence of password digits to the stored password, the smartphone. |
