Presentation by Roman Miletitch
This was a description and video demo about a device Roman and Jérémie Cortial have been working on. It’s a combination of bespoke hardware, running some open libraries, to allow drawing on paper with colored markers, which are then digitized and represented digitally.
The specific use they have mostly been working with is to create interactively a digital pinball machine, with as many reiterations of design-play-redesign-play as you would like. Although they have not pursued this in other directions, the libraries are open source and might be used for other ideas.
