Proportion: a tablet app for collaborative learning

Everyday computing technology is transitioning from PCs to more natural user interfaces. At the forefront of this trend are multi-touch tablets. Each year, tablets become more affordable, capable and widespread. Now is the time for research to shape how they will be used to support learning. In this paper, I introduce the Proportion tablet application as both a concrete vision of how tablets can be used to support co-located collaborative learning and as a research platform for investigating that possibility. I motivate the work, describe how the design has evolved and outline the questions this design-based research aims to address.
