Abstract
According to an embodiment, a method includes collecting, by a time-of-flight (ToF) sensor, real time raw data of a scene comprising a user in its field of view; generating, by a first neural network, an estimate of a posture of the user based on a distance calculated to the user; generating, by a second neural network and in response to determining that the estimate of the posture of the user meets a first criterion, an estimate of a head orientation of the user based on the distance, a standard deviation of the distance, the number of photons returning per unit of time, a standard deviation of the signal value, and a reflection value; and transitioning from low-power to normal mode in response to determining that the user is actively engaged with the device based on the estimate of the head orientation of the user.
