This is a kiosk I built with MAGFest in mind, but it could be applied to any conference type of situation. It uses infrared lasers, ps eye, ccv, and html5.
Maybe you cover this in the video - but I have no sound so I can not know..:
What software and Frameworks did you use to build this?
I guess it is web based as you mention HTML5....
The graphic interface is html5 and the touch is done with CCV and EcoTUi driver.
