    Creative Sound Modeling with Signed Distance Fields
    (Mensch und Computer 2022 - Workshopband, 2022) Mende, Tendsin; Engeln, Lars; McGinity, Matthew; Groh, Rainer
    Wavetable synthesisers often use 2D or 3D surface representations to visualise the internal table of values that produce the final audio waveform. This representation can be used to extend the expressiveness of synthesizers, by allowing more intuitive creation and manipulation of the 3D forms. In this work we explore the use of Signed Distance Fields (SDF) for representing and visualising 3D wavetables. SDF representations allow intuitive interactive sculpting and animation of 3D forms. We demonstrate different methods for transforming these forms into sound in real-time, by intersecting arbitrary 2D surfaces with the 3D forms and interpreting the results as sound, in both time and frequency domains. This extends the concept of wavetable synthesizers, and as SDFs lend themselves to real-time, immersive display and interaction through motion and gesture, the technique can be used to construct novel interfaces for musical expression.

    Stretching Projection - Projection-based Visual Control and Support for Sports Exercises
    (Mensch und Computer 2022 - Tagungsband, 2022) Franke, Ingmar S.; Elze, Annika; McGinity, Matthew
    Various fitness trackers make it possible to check vital signs, count steps or measure the duration of an exercise. However, a fitness tracker does not provide information about the correct execution of a sport exercise. This is the motivation for our contribution. We introduce the concept of an interactive training environment using the example of stretching exercises in the form of a computer-based visual feedback system, which is intended to increase the efficiency and safety of a training session. We answer the question: How can such a system be designed?
