More than one attendee of the Multitouch and Surface Computing Workshop at CHI 2009 made sure that I was aware of a touch-based informational kiosk at the conventional center… Note that there are three cues to the user to hint that it is touch-enabled. For applications that run on Microsoft Surface, I find that users tend to know that they should use touch to interact with the unit when there is some “organic” or random movements of some UI objects. Our Water (Attract) is a great example. Additionally, the use of a “severed” hand (as seen in the photo) ought to be considered carefully for deployment in certain culture.
