    The friday afternoon project: A two-hour voodooio prototyping exercise

    VoodooIO is a new architecture for physical user interfaces, providing interface devices that can be flexibly arranged on an interactive substrate. The architecture supports rapid assembly of physical interfaces and dynamic rearrangement of devices. In this paper we provide an account of a case study in which VoodooIO was used to rapidly build and explore a physical interface to an existing application, Google Earth. The case study gives insight into VoodooIO's support for rapid prototyping of physical user interface applications.

    Locating physical interface objects on interactive surfaces
    (INFORMATIK 2006 – Informatik für Menschen – Band 2, Beiträge der 36. Jahrestagung der Gesellschaft für Informatik e.V. (GI), 2006) Block, Florian; Gellersen, Hans; Hazas, Mike; Molyneaux, David; Villar, Nicolas
    Pin&Play has enabled a new type of surface-based physical user interface, characterised by dynamic arrangement of interface objects on a surface area. Previous work has shown that this affords rapid re-arrangement of the spatial layout of interface objects, for example in adaptation to user preferences, but the Pin&Play system did not support tracking of object locations on the surface. In this paper, we investigate and compare two practical location techniques for interactive surfaces that are based on external sensing: detection of surface events using load sensors, and camera-based detection using object beacons.
