Conversational engagement and mobile technology use

The present work investigated effects of mobility constraints on gesturing and other aspects of conversational engagement when using mobile technology. Based on studies of non-verbal communication and interaction quality, we compared mobile and static forms of video call in structured interviews. Using real-time motion capture and content coding of recordings as well as self-reports, several data sources were considered: hand velocity as an indicator of gesturing, observed levels of engagement and remembered conversational content. Gesturing, in contrast to other indicators of engagement, was reduced under high mobility constraints and was more pronounced under low constraints. Gesturing was further positively related to observed engagement. Additionally, lower constraints resulted in more memories of conversational content. These findings emphasise the relevance of mobility constraints and bodily movement during mediated interaction and call for further model development in computer-mediated communication. Potential for application lies in interactive scenarios such as remote interviewing, testimonials, and relationship maintenance.
