Summary:A non-contact gesture control method and an electronic device (100). The method is applied to an electronic device (100), and the electronic device (100) comprises: at least one loudspeaker (23) and at least one microphone (24). The method comprises: displaying a target application (28), the target application (28) being an application program that supports non-contact gesture recognition (S101); starting the at least one loudspeaker (23) to transmit an autocorrelated ultrasonic signal (S102); starting the at least one microphone (24) to collect a reflecting signal reflected after the ultrasonic signal encounters a non-contact gesture (S103); and controlling, according to the target application (28) and the reflecting signal, the target application (28) to respond to the non-contact gesture (S104). In this case, the electronic device (100) can accurately realize the human-computer interaction of the non-contact gesture in the target application (28), without considering the constraints such as light in a surr
