Abstract

A facial expression sensing method including acquiring radar data from a radar sensor configured to perform range sensing in an environment including a person, analysing the radar data to determine facial radar data indicative of radar data captured from a face of the person, determining a facial expression by using facial radar data and at least one computational model, the at least one computational model being at least partially indicative of relationships between facial radar data and different facial expressions and generating an indication of the facial expression.
