Multi-touch interaction techniques are becoming more widespread because of new industrial initiatives to make this hardware available and affordable for the consumer market. To cope with the diversity in hardware setups and the lack of knowledge about developing generic multitouch applications, we created a framework, Eunomia, for ing the hardware from the software and to enable software developers to easily develop interactive applications taking advantage of multi-touch interaction. We describe our first set of applications created on top of this framework that are targeted for public spaces. During the deployment of these applications, we were able to observe users that are confronted with multi-touch technologies in a public space.
