SOCIAL INTERACTION DESIGN:

Social interaction design is emerging because many of our computing devices have become networked and have begun to integrate communication capabilities. Phones, digital assistants and the myriad connected devices from computers to games facilitate talk and social interaction.  Social interaction design accounts for interactions among users as well as between users and their devices. The dynamics of interpersonal communication, speech and writing, the pragmatics of talk and interaction--these now become critical factors in the use of social technologies. And they are factors described less by an approach steeped in the rational choice approach taken by cognitive science than that by sociology, psychology  and anthropology
