Alavi, Ali, Clocher, Brice, Smith, Allab, Kunz, Andreas M. and Fjeld, Morten (2011): Multi-State Device Tracking for Tangible Tabletops. In: SIGRAD Swedish Chapter of Eurographics November 17-18, 2011, Stockholm, Sweden. . Available online

Tangible tabletops where actively emitting devices (TUIs) are tracked to inform about their identity, position, orientation, and state can provide rich interaction within complex, dynamic scenarios. TUI states assuming values over a highresolution large range requires sending many bits for each update and comes at the cost of system update rate. In the first part of this paper, we present an in-house map application where interaction with time-dependent contour lines may benefit from high-resolution TUI states. Prototypical TUI concepts such as slider, ruler, and knobs further motivate the benefit of high-resolution tracking. In the second part of the paper, we depart from a device tracking overview and then show how tangible devices for tabletops typically use infrared (IR) emitters and a camera to send information about their position, orientation, and state. We propose a method that can be realized as a tabletop system using a low-cost camera detecting position combined with a low-cost infrared receiver detecting the state of each device. Since both kinds of sensors are used simultaneously we call the method _dual mode._ This method offers high-resolution tracking without having to compromise on update rate
