Abstract: This application is directed to a method for controlling user experience (UX) operations on an electronic device that executes an application. A touchless UX operation associated with the application has an initiation condition including at least detection of a presence and a gesture in a required proximity range with a required confidence level. The electronic device then determines from a first sensor signal the proximity of the presence with respect to the electronic device. In accordance with a determination that the determined proximity is in the required proximity range, the electronic device determines from a second sensor signal a gesture associated with the proximity of the presence and an associated confidence level of the determination of the gesture. In accordance with a determination that the determined gesture and associated confidence level satisfy the initiation condition, the electronic device initializes the touchless UX operation associated with the application.

Abstract: The various embodiments described herein include methods, devices, and systems for ultrasonic sensing on electronic devices. In one aspect, a method is performed at an electronic device having memory, one or more processors, a speaker, and a microphone. The method includes, while audibly communicating with a user via the speaker and microphone: (1) sending one or more ultrasound pulses via the speaker; (2) receiving, via the microphone, one or more signals corresponding to the one or more ultrasound pulses; (3) determining positioning of the user based on the one or more received signals; and (4) adjusting one or more parameters of the speaker and/or the microphone based on the determined positioning.

Abstract: An electronic device has memory, one or more processors, a speaker, and a microphone. The device sends a first set of ultrasound chirps at a first rate via the speaker. It receives, via the microphone, a first set of signals corresponding to the first set of ultrasound chirps and being reflected from a person. The device determines based on the first set of signals that the person is in proximity to the electronic device. In accordance with the determination that the person is in proximity to the electronic device, the device sends a second set of ultrasound chirps at a second rate, faster than the first rate. It receives, via the microphone, a second set of signals corresponding to the second set of ultrasound chirps, and identifies a gesture from the person based on the second set of signals.
