Pictionaire: Multi-touch table that integrates physical and digital objects from Microsoft Research
Another interesting MSR multi-touch project: Pictionaire This research project combines computer object recognition and Surface style multitouch interactions for collaboration.
It’s based on a modified version of the Surface SDK
It is really easy to add custom touch devices in WPF4 (I’ll write about that in the next post). I'm hoping to see a lot more experimentations around new multi-touch input methods in the community.
