AI technology and systems are increasingly used in devices and systems that are part of the pervasive computing fabric of the world. However, people are critical in the design, operation, and use of those AI systems, and society has to ensure that those systems operate transparently, promote equitable outcomes, respect privacy, and effectively serve people’s needs. In this context, this special section focuses on human-centered AI provides a forum for papers investigating new forms of human–AI interactions and experiences that enhance and extend human capabilities in the context of pervasive applications and systems.
