The application relates to the technical field of
mobile phone screen unlocking, and relates to a
mobile phone screen unlocking method based on
gesture recognition. The method comprises the following steps: S1, touch detection is performed on a
mobile phone screen, so that a real-time touch pattern and a real-time
completion time are generated; and S2, standard touch patterns and hand image data of set gesture types are collected. The application adjusts a time threshold value according to a formula by counting the average
completion time of historical gesture operations of a user, so that the time threshold value is automatically lengthened if the actual
operation time of the user is generally longer than the standard
completion time, and the time threshold value is shortened if the actual
operation time is shorter, the adjustment of the time threshold value avoids misjudgment caused by slow user operation speed, the unlocking is more in line with the actual operation
rhythm of the user, and meanwhile, the basic deviation threshold value is adjusted according to the real-time completion time in the gesture comparison link, the adjustment avoids unlocking obstruction caused by
temporary operation state fluctuation of the user, guarantees the rationality of judgment, and greatly improves operation convenience.
