The silent vocabulary of human evolution and physical expression
In short: Our bodies often broadcast our internal states before we ever find the words to speak. This documentary explores the science behind non-verbal communication, from evolutionary roots to modern technological recognition.
The film examines how scientists study bodily communication across diverse fields including psychology, security, commerce, and interpersonal relationships. It traces the origins of these signals through human evolution and emotion research.
Beyond human interaction, the documentary highlights how technology is currently being developed to recognize and interpret human expressions automatically.
