Andrew Schretter from Duke’s Math Department was in the market for an interactive projection system and has shared his thoughts on the Epson Brightlink 696Ui which was supplied to us for testing courtesy of Erik Benson of Kontek.
As far as testing goes, it is a bit tricky to set up properly, you need to make sure the touch sensor is positioned above the screen and calibrating can be a bit tricky with the included markers. But once we had that done, it appears to work fine for our intended usage. Google chrome seems to cause a lot of problems since it has built in touch gesture support and you can’t disable it (things like pinch zoom, swipe to move forward and back pages, and right click that inexplicably supercedes any javascript in the page to disable it). I’m still working on making chrome work for us. The touch clicking also seems to get stuck a bit with chrome, probably because of bad multitouch support. Its as if the touch gets stuck with mouse button down.
