Problems solved by technology

However, infrared rays are often reflected by other positions in the gesture except for the pulp of the finger. This method is likely to generate interference signals due to the large gesture area, which in turn leads to a decrease in the accuracy of gesture recognition and is prone to misuse. Poor experience

Abstract

The invention discloses a method and device for unlocking a mobile terminal. The method comprises the following steps: transmitting an ultrasonic signal through a plurality of ultrasonic sensors arranged on the mobile terminal; determining the ultrasonic sensor which detects an ultrasonic reflection signal with the change of a signal value, and determining a key position, corresponding to an unlocking interface, of a gesture of a user according to the ultrasonic reflection signal detected by the determined ultrasonic sensor; and judging whether the mobile terminal is unlocked or not according to a password factor on the determined key position. With the adoption of the method and device disclosed by the invention, the gesture of the user can be rapidly and accurately identified, the effect of incorrect operation caused by interference signals is avoided and the application experience of the user is improved.

Description

technical field [0001] Embodiments of the present invention relate to screen unlocking technologies, and in particular to a method and device for unlocking a mobile terminal. Background technique [0002] At present, many electronic products are equipped with intelligent recognition technology, especially gesture recognition, which is widely used. For example, existing mobile phones, many mobile phone manufacturers have added gesture recognition functions to mobile phones. Users do not need to touch the mobile phone, but only need to make corresponding gestures You can operate the mobile phone, such as entering the password to unlock the mobile phone through the air, turning pages through non-contact control of gestures, etc. [0003] In the existing non-contact gesture control unlocking methods, most of them use a camera to acquire the user's gestures, and extract the user's gesture movement trajectory through image processing to perform the unlocking operation. This metho...
