A short document to illustrate a project by Diana Nowacka. This work presents actuated graspable interfaces that employ physical objects to allow users to interact with a computer application. Active tangibles are enhanced by motors which make the tangibles movable and allow multi-touch surfaces to steer them. Since the tangibles consist of printed-circuit boards, they are enhanced by several sensors which provide a wide range of features for input and sensing. Touchbugs can not only be used as controls on interactive surfaces, but because of their ability to be programmed and therefore to act in a goal-directed fashion, can guide users during their interaction. They can assist in tasks like image processing or writing documents on interactive horizontal surfaces.
