Spatially aware tangible displays are a promising approach for extending the interaction space of conventional tabletops from the 2D surface to the 3D physical space above it. This is achieved by utilizing the position and orientation of lightweight tracked displays, which allows for a natural and intuitive way to interact with complex information spaces. Technical solutions for such systems already exist in research labs. However, they usually are expensive, complex, and difficult to maintain and thus are inappropriate for a broad audience. With our work, we want to address this issue. In a long term, we envision a low-cost tangible display system that supports both active displays (e.g., the iPad) and passive displays (e.g., paper screens and everyday objects such as a mug). In this paper, we take the initial step into this direction by presenting a proof of concept system that supports active displays. Along with the application of a consumer depth camera (Kinect), this reduces the costs by more than an order of magnitude.
