    Musical similarity analysis based on chroma features and text retrieval methods
    (Datenbanksysteme für Business, Technologie und Web (BTW 2015) - Workshopband, 2015) Englmeier, David; Hubig, Nina; Goebl, Sebastian; Böhm, Christian
    At the present day the world wide web is full of music. Highly effective algorithms for music compression and high data storage has made it easy to access all kind of music easily. However, it is not possible to look for a similar piece of music or a sound as easily as to google for a similar kind of text. Music is filtered by its title or artist. Although musicians can publish their compositions in a second, they will only be found by high youtube ratings or by market basket analysis. Less known artists need much luck to get heard, although their music might just be what people want to hear. To approach this issue, we propose a new framework called MIRA (Music Information Retrieval Application) for analyzing audio files with existing Information Retrieval (IR) methods. Text retrieval has already yielded many highly efficient and generally accepted methods to assess the semantic distance of different text. We use these methods by translating music into equivalent audio words based on chroma features. We show that our framework can easily match music interpreted even by different artists.

    Spherical Objects as an Opportunity to Investigate Physical Embodiment in Mixed Reality Environments
    (Mensch und Computer 2019 - Workshopband, 2019) Englmeier, David
    In this work, we introduce our approach of using current VR and AR technology to explore fully tangible spherical user interfaces.We present three prototypes utilizing this technique. We briefly outline possible challenges, advantages, and fields of application for the presented concepts. Accordingly, we discuss why VR is an interesting tool to investigate interaction with Tangible User Interfaces (TUIs) that are currently not feasible in real world applications such as tangible holographic interfaces or lightweight handheld non-planar displays.This allows for studying various levels of tangible feedback on established use cases such as spherical visualizations. Subsequently, a tangible sphere, due to its natural shape enables an investigation of interaction techniques transferred from the real to the virtual world. Building on these prospects we represent the position that such objects could play a leading role not only in research but in future Virtual Reality (VR) and Augmented Reality (AR) applications that rely on natural interaction based on realistic physical feedback.
