SLIDE UNLOCKING METHOD FOR TOUCHSCREEN DEVICE UNDER SCREEN LOCKING STATE

摘要

A slide unlocking method for a touchscreen device under a screen locking state is provided. The method comprises steps of: sampling a track generated by the sliding of a user's finger on a touchscreen, and sequentially acquiring a plurality of sampling points; acquiring a first sampling point and a last sampling point of the track, and calculating a transverse sliding distance of the finger on the touchscreen and a longitudinal sliding distance of the finger on the touchscreen; and unlocking the touchscreen when the transverse sliding distance is greater than or equal to a first preset distance and the longitudinal sliding distance is less than or equal to a second preset distance, and keeping the screen in the lock state when the transverse sliding distance is less than the first preset distance or the longitudinal sliding distance is greater than the second preset distance. In this way, the present invention increases the degrees of freedom of a user's operation, so that a user can conveniently perform unlocking in a special usage scenario.
