Affective Computing For Accessibility

What is Affective Computing?

Affective computing is a multidisciplinary field that combines computer science, psychology, and cognitive science to develop systems capable of recognizing, interpreting, and responding to human emotions. It involves the use of sensors, algorithms, and artificial intelligence to analyze emotional cues such as facial expressions, voice tone, and physiological signals. In the context of smart cities, affective computing enables urban systems to adapt to the emotional states of residents, fostering environments that are more responsive and human-centric.

For example, imagine a public transportation system that detects passenger stress levels during peak hours and adjusts its operations to reduce overcrowding. Or consider a smart lighting system that dims or brightens based on the mood of individuals in a public space. These applications illustrate how affective computing can enhance the functionality and user experience of smart city technologies.
