Personal Mobile Messaging in Context

Mobile text messaging is one of the most important communication channels today, but it suffers from lack ofexpressiveness, context and emotional awareness, compared to face-to-face communication. We address thisproblem by augmenting text messaging with information about users and contexts. We present and reflect onlessons learned from three field studies, in which we deployed augmentation concepts as prototype chat appsin users’ daily lives. We studied (1) subtly conveying context via dynamic font personalisation (TapScript),(2) integrating and sharing physiological data – namely heart rate – implicitly or explicitly (HeartChat) and(3) automatic annotation of various context cues: music, distance, weather and activities (ContextChat). Basedon our studies, we discuss chat augmentation with respect to privacy concerns, understandability, connectedness and inferring context in addition to methodological lessons learned. Finally, we propose a design spacefor chat augmentation to guide future research, and conclude with practical design implications.
