This system enables users to create room-sized interactive surfaces with spray paint via Arduino Blog
If you’ve ever thought of adding a user interface to an everyday surface — like a concrete wall, or even a sofa — MIT CSAIL’s SprayableTech system presents a variety of interesting possibilities.
Input elements, such as buttons and sliders, are airbrushed onto a surface like graffiti with a single layer of conductive ink, while electroluminescent displays can be formed by the application of multiple layers with different properties. Spray paint stencils for these interfaces are created with the help of a toolkit integrated into Blender.
