Abstract: The present disclosure relates to a system includes a microcontroller including a neural network, a time-of-flight sensor including a plurality of pixels and configured to perform a capture of a scene comprising a user, the capture comprising, for each pixel, the measurement of a distance from the user and of a signal value. The sensor is further configured to calculate a value of a standard deviation associated with the distance value, and a value of a standard deviation associated with the signal value and a confidence value. The sensor is further configured to provide the values to the neural network. The neural network is configured to generate, based on the values, an estimate of a direction associated with the user. The system further includes a display, the microcontroller is configured to control the display, or another circuit, based on the estimate.
