Human verbal and nonverbal expressions carry crucial information not only about intent
but also emotions, individual identity, and the state of health and wellbeing. From
a basic science perspective, understanding how such rich information is encoded in
...
Abstract: How can we create technologies to help us reflect on and change our behavior,
improving our health and overall wellbeing? In this talk, I will briefly describe
the last several years of work our research team has been doing in this area. We ...
What are facial expressions for? In social-functional accounts, they are efficient
adaptations that are used flexibly to address the problems inherent to successful
social living. Facial expressions both broadcast emotions and regulate the emotions
of ...
Humans interact with the world using five major senses: sight, hearing, touch, smell,
and taste. Almost all interaction with the environment is naturally multimodal, as
audio, tactile or paralinguistic cues provide confirmation for physical actions and
