This document summarizes three interactive tabletop systems: Teaching Table, SciSketch, and SketchTop. Teaching Table is an interactive tabletop device used for pre-K math education with tangible objects, visual/audio output, and assessment tools. SciSketch is a low-cost digital tabletop that allows collaborative sketching with IR pens on a whiteboard for diagrams, charts, and 3D models. SketchTop is a multi-touch tabletop system that enables collaborative design across disciplines through synchronous communication, creation and sharing of designs.
