Abstract

There are situations under which co-located people are required to perform collaborative marking tasks: for example, human resource officers need to review resumes together and teachers need to grade answer sheets after an examination. In this poster, we introduce PiMarking, a collaborative system designed to accommodate user-authenticated marking tasks and face-to-face discussions on large-scale interactive tabletop surfaces. PiMarking makes it easy for user-differentiation, document sharing and synchronized marking among group members. PiMarking puts forward user permission management mechanisms, allowing three modes for document sharing: distributed copy, share display and synchronized marking. We conducted a preliminary study using a realistic resume marking task, which proved the effectiveness of the features provided by PiMarking.
