RetroTime: retrospectively visualizing and labeling time intervals

RetroTime is a system that allows users to easily label temporal data streams. Having such a tool is important to support Pervasive Computing applications that depend on accurate data to feed to supervised machine learning algorithms. This paper describes the user experience using RetroTime, and describes how it could be extended to support more complex labeling tasks, particularly in multi-person environments.
