AI Technical Summary

Technical Problem

Existing digital passwords, gesture passwords, fingerprint passwords, or other biometric password unlocking methods are difficult for blind or visually impaired individuals to input accurately, resulting in low accuracy of pattern unlocking.

Method used

The system collects the trajectory coordinates of the unlock pattern of the target object in a preset coordinate system, filters out the start and end coordinates, constructs the target coordinate system, converts it into a target coordinate set, and calculates the coordinate distance to the preset pattern for unlocking. It allows input of any start point, size, and direction.

Benefits of technology

It improves the accuracy of pattern unlocking, making the unlocking process unnecessary for specific paradigms and fixed requirements, and suitable for special users.

Abstract

Embodiments of the present application disclose a pattern unlocking method and related devices, which can include a pattern unlocking device, an electronic device, a computer program product and a computer readable storage medium; after obtaining a set of original coordinates of a target object in a preset coordinate system by collecting a trajectory of a target object, the original coordinates of the target object are filtered to obtain a starting point coordinate of a starting point of a pattern and an ending point coordinate of an ending point of the pattern, and then a target coordinate system corresponding to the starting point and the ending point is constructed based on the starting point coordinate and the ending point coordinate, the original coordinates in the original coordinate set are converted into coordinates in the target coordinate system according to the starting point coordinate, and a set of target coordinates is obtained, and then a coordinate distance between the set of target coordinates and a set of coordinates of at least one preset pattern is calculated to unlock the target object; the scheme can improve the accuracy of pattern unlocking for special users.
