Systems and methods for detecting gestures using ultrasonic clicks are described. For example, some methods include playing an ultrasonic click using an audio driver, wherein the ultrasonic click is a modulated audio pulse with a duration less than one hundred periods of a modulation frequency waveform of the ultrasonic click; accessing a recording, captured using a microphone, of the ultrasonic click; applying an ultrasonic bandpass filter to the recording to obtain a filtered signal; determining a classification of a gesture based on the filtered signal; and transmitting, storing, or displaying an indication of the classification of the gesture.
