Abstract
An embodiment method may include receiving radar data at a millimeter-wave radar sensor, the radar data being generated in response to an incident radio-frequency signal reflecting off a biological target located in a field of view of the millimeter-wave radar sensor; extracting a filtered vital-Doppler signal from the radar data; determining an emotion of the biological target based on the filtered vital-Doppler signal; and generating a user-engagement rating indicative of a level of engagement of the biological target in an activity performed in the field of view based on the emotion.
