Researchers from the The Media Computing Group at RWTH Aachen University, introduced a new concept, called SLAP Widgets, that combines soft controls with tangible controls. It's a nice application of tangible computing and something that might work very well with Microsoft Surface.SLAP (Silicone Illuminated Active Peripherals) are input devices formed of transparent silicone including buttons, dials, sliders, and a keyboard. The SLAP widgets are placed on the multitouch surface and, using tag recognition, labels and indicators are projected on the table surface just below the physical peripherals. It's a very cool idea, one that is similar in some ways to Microsoft SecondLight, which can project above the screen into tangible objects, but SLAP seems simpler to implement.
I especially like the SLAP keyboard which addresses the difficult issue of using keyboards on multitouch surfaces without haptic feedback. There is a really nice video and you can learn more on their site. Nice work guys! (thanks to Jonathan Brill for pointing this out on his blog).
