Chapter 5: Social Interaction in Design

Social Interaction in Design details the intricate mechanisms governing human communication, noting that face-to-face dialogue is a highly skilled collaborative achievement involving mutual greetings, specific cues for closing conversations (implicit or explicit), and farewell rituals. Central to this coordination are turn-taking rules (Sacks et al., 1978), which dictate when speakers listen, speak, or continue talking, and adjacency pairs (Schegloff and Sacks, 1973), where one utterance sets an expectation for the next. When communication falters, participants employ repair mechanisms, using gestures, voice intonation, or tokens like "Huh?" to clarify misunderstandings. In remote conversations, technologies from early videophones and media spaces like the VideoWindow evolved into modern videoconferencing. Concepts defining remote presence include telepresence, which is the perception of being physically remote while feeling present (often facilitated by robots like Beam+), and social presence, which describes the feeling of being with a real person in a virtual environment (as seen in Facebook Spaces). The text also covers co-presence, focusing on supporting interaction in the same physical space through coordination mechanisms like talk, nonverbal communication, and the use of physical objects. Crucial to collaboration is awareness, broken down into peripheral awareness (constantly updating a sense of the surrounding social and physical context) and situational awareness (understanding how current events and actions affect the future). Designing group systems involves creating shareable interfaces (multitouch tables, whiteboards) that support parallel interaction and can encourage more equitable participation, potentially benefiting shy or non-native speakers. The principle of social translucence emphasizes making participants' activities visible, exemplified by systems like Babble and Sococo’s online office maps. The chapter concludes by discussing the profound impact of social media, which has dramatically changed social networks and work practices, introducing new social phenomena such as the rise of digital volunteers who use platforms like Twitter to provide rapid, widespread information (though reliability remains a concern). This networked connectivity enables various forms of social engagement, including large-scale viral events (like the Carter Wilkerson "Chicken Nugget Battle") and organized pro-social activities like citizen science. The increased use of communication technology also raises sociological dilemmas, such as the observed decrease in face-to-face conversation leading to a potential loss of empathy, and ethical issues, such as creating chatbots from a deceased person's texts.
