Retrospective vs. Prospective: A comparison of two approaches to mobile media capture and access


Mobile media applications need to balance user and group goals, attentional constraints, and limited screen real estate. In this paper, we describe the development and testing of two application sketches designed to explore these tradeoffs. The first is retrospective and time-
based and the second is prospective and space-based. We found that attentional demands dominate and mobile media applications should therefore be lightweight and hands-free as much as possible.
