This paper charts the design and build of two interactive tabletops that use infrared (IR) illumination techniques. One table implements fiducial tracking, whilst the other implements multi-touch tracking. Trade-offs in both designs are discussed to highlight key considerations when building an interactive table. Using three key dimensions from lessons learned, we conduct a comparative analysis of both approaches. Finally, we propose a DIY Design Process to assist designers in building their own interactive table.
