Assistant control via detecting tactile modulation of ultrasonic signal

A method implemented by one or more processors, the method comprising:

• causing an output interface of a computing device to render a signal that can be captured by a first microphone and a second microphone of the computing device,
• wherein the computing device includes an automated assistant application that provides access to an automated assistant that can be responsive to natural language input from a user;
• processing a first instance of audio data that characterizes input received by the first microphone and a second instance of audio data that characterizes separate input received by the second microphone,
• wherein the input and the separate input are received simultaneous to the output interface rendering the signal;
• determining, based on processing the first instance of audio data and the second instance of audio data, whether the user provided a touch input gesture that caused the input to exhibit a particular signal characteristic before or after the separate input exhibited the particular signal characteristic;
• and
• causing, in response to the user providing the touch input gesture, the automated assistant to initialize performance of one or more operations according to whether the input exhibited the particular signal characteristic before or after the separate input exhibited the particular signal characteristic.

A method implemented by one or more processors, the method comprising:

• causing an audio output interface of a computing device to render an acoustic signal that embodies one or more ultrasonic frequencies,
• wherein the computing device is in communication, via a wireless communication protocol, with a separate computing device that provides access to one or more applications;
• processing audio data generated by an audio input interface that is attached to a housing of the computing device,
• wherein the audio data is generated during rendering of the acoustic signal by the audio output interface of the computing device;
• determining, based on processing the audio data, that a user provided a touch gesture to the housing of the computing device,
• wherein the touch gesture to the housing modifies an acoustic signal received by the audio input interface when audio output interface is rendering the acoustic signal;
• and
• causing, based on the touch gesture to the housing of the computing device, the computing device to control the one or more applications of the separate computing device in response to the user providing the touch gesture.
