Designing for Common Ground: Visually Representing Conversation Dynamics of Neurodiverse Dyads

Abstract

During interpersonal interactions, conversational moves can help people establishcommon ground ---a shared frame of reference to support communication. Neurodiverse conversation dyads that include autistic and non-autistic members can experience challenges in creating and maintaining such a shared frame of reference due to differing communication and cognitive styles. We conducted a design study to understand conversational patterns among neurodiverse dyads and then used those patterns to co-design concepts for supporting the creation and maintenance of common ground by those conversation pairs. Our study involved two activities with participants: (1) a paired interview with autistic adults and a trusted conversation partner that used a novel swimlane visual elicitation activity, and (2) a remote design study during which the autistic participants designed a game intended to visualize and support neurodiverse conversation dynamics. We found that communication technology can scaffold neurodiverse dyads in locating common ground by supporting crucial individual and joint decision-making; clarification of language and emotions; and embodied sense-making of identity, relationships, and shared information. This project generated insights related to two distinct aspects of designing assistive Information and Communication Technology (ICT) to support autistic individuals: (1) the ability for visual elicitation activities to help autistic individuals recognize interaction patterns, gain a deeper understanding of other's perspectives, and imagine more desirable alternatives, and (2) the importance of recognizing and supporting multi-dimensional aspects of communication practices (i.e., social, emotional, sensory) in establishing and maintaining shared points of reference for neurodiverse conversation dyads.
