Abstract
A method for alerting a user on an electronic device is described. The method includes identifying a signal at an ultrasound transmission frequency received at a first electronic device from a second electronic device. Further, the method includes receiving timing information corresponding to an exchange of an ultrasound transmission between the first electronic device and the second electronic device. Furthermore, a first distance value between the first electronic device and the second electronic device is computed by performing a time of flight estimation using the timing information. Furthermore, the first distance value is refined by using an output of a machine learning model to determine a second distance value. Furthermore, the method includes generating an alert based on the comparison of the second distance value with a predefined threshold distance value. In some examples, the alert can be indicative of a violation of a physical distancing norm in an environment.
