FourBySix is a large, multi-user, multi-touch table designed to
facilitate creative group work. It measures, predictably enough, 4' by 6'.
FourBySix combines top projection with camera-based multi-touch input and
object tracking from below; support for multiple sets of keyboard and mice;
and high-resolution image acquisition through a top-mounted digital still
camera. I built FourBySix during an internship at Microsoft Research in
2008 with collaborators Merrie Morris, Hrvoje Benko, and Andy Wilson. We are in the process of publishing two papers on this system - one
about new techniques for integrating mouse and keyboard input on interactive
surfaces (UIST2009), and one on a software system, Pictionaire, that supports design
team meetings (CSCW2010).

The following video demonstrates new interaction techniques we developed for integrating keyboard and mouse support on a multi-touch table:

Others have used FourBySix for their research as well- Rebecca Fiebrink and Dan Morris published a paper on tradeoffs between physical and virtual controls at CHI 09. In their system, multiple physical musical controllers are used in combination with multitouch input for a collaborative multitrack music editing application.
