Embodiment Construction
[0095] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.
[0096] When a user uses a mobile terminal with a touch screen, in the process of answering a call, it is easy to accidentally touch the call stop button due to contact between the touch screen and the face, which affects the user's normal call. If the movement of the mobile terminal approaching the face can be detected timely and accurately, the touch function of the touch screen can be disabled...

The invention relates to a method and device for preventing a screen from being touched by mistake and a storage medium. The method comprises the steps of sending out a band-pass ultrasonic signal; receiving a reflected ultrasonic signal; calculating frequency domain information of the reflected ultrasonic signal; calculating at least one ultrasonic feature vector according to the frequency domain information, wherein the ultrasonic feature vector is used for representing the motion state information of a mobile terminal approaching or far away from an obstacle; constructing a feature vector set comprising the at least one ultrasonic feature vector; judging whether a mistaken touch prevention condition is met or not according to the feature vector set; and when the mistaken touch prevention condition is met, forbidding the touch control function of a touch screen. According to the method and the device, the movement condition of the mobile terminal can be more accurately obtained, the accuracy of disabling the touch function of the touch screen is improved, a user is effectively prevented from mistakenly touching the touch screen, and particularly call interruption caused by contact between the touch screen and the face in the call process can be effectively prevented.
Description
technical field [0001] The present disclosure relates to mobile terminal data processing technologies, and in particular to a method, device and storage medium for preventing false screen touches. Background technique [0002] With the rapid development of communication technology, mobile terminals have been widely used.
