Real-time document collaboration using iPads

This paper presents a real-time collaborative interface for reading groups. We exploit the light and portable properties of iPad hardware to facilitate an intimate interaction experience that gives users the ability to simultaneously mark up their own copy of a document, while instantly viewing notes made by other members of the group. We also introduce a tool that allows group members to quickly `point out' information within a document to other members without physically gesturing with their hands. We finish with a short explanation of a study proposed to test the implemented system.
