While conducting research on emotions and facial expressions in Papua New Guinea in , psychologist Carlos Crivelli discovered something startling. He showed Trobriand Islanders photographs of the standard Western face of fear — wide-eyed, mouth agape — and asked them to identify what they saw. Instead, they saw an indication of threat and aggression. But if Trobrianders have a different interpretation of facial expressions, what does that mean? Instead of reliable readouts of our emotional states, they show our intentions and social goals. Our smiles and frowns may well be instinctive.

Exaggeration of facial expressions is used in animation and robotics to intensify emotions. However, modifying a human-like face can lead to an unsettling outcome. This phenomenon is known as uncanny valley. The goal of this study was to identify the realism level and magnitude of facial expression that produce the maximum amount of emotional intensity and the minimum amount of perceived strangeness. We studied the perceived intensity of emotion and perceived strangeness of faces with varying levels of realism from schematic to photorealistic and magnitude of facial expressions from neutral to extremely exaggerated. We found that less realistic faces required more exaggeration to reach the emotional intensity of a real human face.

Investigating human nature and communication through robots View all 10 Articles. We propose an expression transmission system using a cellular-phone-type teleoperated robot called Elfoid. Elfoid has a soft exterior that provides the look and feel of human skin, and is designed to transmit the speaker's presence to their communication partner using a camera and microphone.
