Affective computing is a multidisciplinary research area that focuses on developing systems and devices that can recognize, interpret, simulate, and process human emotions. This field combines principles from computer science, psychology, cognitive science, and neuroscience to create technology that can detect and respond to human emotions in a natural and intuitive way. Affective computing aims to improve human-computer interaction by making technology more empathetic, responsive, and adaptive to the emotional state of the user. This research area has applications in various fields such as healthcare, education, entertainment, and human-computer interface design.
