There have also been installations of the DiamondTouch that feature conductive floor pads scattered in front of a DT display mounted vertically on the wall. The use of chairs just happens to work well when you're dealing with interaction around a table, which happens to be one of the big research threads coming out of the Mitsubishi Electric lab over the last several years. They've published a number of user studies (many at the ACM CHI conference) about how people interact with information when they're sharing an interactive table-type surface and working face-to-face.
