    Demonstrating Dothraki: Tracking Tangibles Atop Tabletops Through De-Bruijn Tori
    (Mensch und Computer 2021 - Tagungsband, 2021) Schüsselbauer, Dennis; Schmid, Andreas; Wimmer, Raphael
    We demonstrate usage examples and technical properties of Dothraki, an inside-out tracking technique for tangibles on flat surfaces. An optical mouse sensor embedded in the tangible captures a small (36×36 pixel / 1×1 mm), unique section of a black-and-white De-Bruijn dot pattern printed on the surface. Our system efficiently searches the pattern space in order to determine the precise location of the tangible with sub-millimeter accuracy. Our proof-of-concept implementation offers a recognition rate of up to 95%, robust error detection, an update rate of 14 Hz, and a low-latency relative tracking mode. The MuC demonstration encompasses four separate demos that showcase typical application scenarios and features: a magic lens, two tangibles that know each others relative position, a simple geometry application that measures distances and angles, and tangibles that know on which of multiple surfaces they have been placed.

    Using a Hardware Simulation for Automatic Software Performance Model Parameterization
    (Softwaretechnik-Trends Band 43, Heft 2, 2023) Weber, Sebastian
    While the fulfilment of functional requirements during software re-engineering or maintenance can likely be monitored with existing test cases, checking whether quality requirements (e.g. performance) are still satisfied requires additional effort. A developer would have to either measure the target system or analyse it based on models. The precise parameterization of these models is usually based on measurements which require an executable software and the target hard ware. This paper proposes an approach to use hardware simulations for the automatic parameterization of performance models to remove the need for the target hardware. The results show that the accuracy of the hardware simulation for the chosen hardware re quires improvements, if these results are intended to replace measurements. Nevertheless they show the applicability of the approach.
