At the Telekom booth there has been a long kind of bar multi-touch table. It is not rectangular but a curve. However, the quality of the projection has not been even as the creators of this table used different projections and did not get the projection illumination even. The application has been quite simple: Photo and video browsing. Anyway, it is looking very impressive:
At the booth of the state of Hessen, Germany a small Microsoft Surface table has been set up. It has good touch sensitivity and looks quite robust. Besides, the small form factor is very handy for mobility but it is not providing the WOW factor for fairs like the Cebit. On the Surface table there are a few photo and map browsing applications, which has been suited for the state of Hessen’s purposes: On the map the schools in Hessen can be found/browsed and in the photo browsing application it can be played with the photos of the members of the new ministry Cabinet of the state of Hessen. Additionally, a few small business cards have been provided with fiducials, which can be thrown onto the table to start those applications.
Here are the photos:
For me the most impressive installation on the Cebit has not been multi-touch but a grid of small LED balls, which were attached to strings. They have been moved up and down automatically and have changed their color according to patterns. Very impressive. Take a look at the photos:
