Abstract
A method for preventing a false touch of a screen includes: sending a bandpass 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, the ultrasonic feature vector being used to characterize movement state information of the mobile terminal approaching or moving away from an obstacle; constructing a feature vector set comprising the at least one ultrasonic feature vector; determining whether a condition for preventing a false touch is met according to the feature vector set; disabling a touch function of the touch screen in a case where the condition for preventing the false touch is met.
