Elie and I finally had some “free” time to go back to the multi-touch interface. We worked on the core library called Distal. Distal enables us to quickly put together a multi-touch GUI. It takes care of all the contact points [touchPoints], and their interaction with the GUI components (toggle button, dragable button, slider, dock, etc.). We are also using ezGesture, which is a gesture recognition library for Processing recently released by Elie. So far, it is only used to interact with the docks containing the GUI ; one finger sliding from right to left in a specific area of the surface will make the dock appears.
Here are some visuals created using facecloth and a video showing the interaction/process.
