One more session again! Now that you’re more skilled, let’s introduce a new way to interact using Arduino+processing to control a video projection. The first attempt will consist in showing/hiding a video according to the sensor output, in order to explore a new field of the physical interaction. This is very useful, specially when the video is projected, in order to map information over surfaces and showing them according to some interactions. We’ll bring the Arduino and the beamer, you’ll come with a couple of videos (text informations, infographics etc etc) or at least some pictures (text informations, infographics etc etc) to be projected.
