    Immersive Experience of Multidimensional Data using Mixed Reality based Scatterplots
    (Mensch und Computer 2022 - Tagungsband, 2022) Potthast, Jonas; Grimm, Valentin; Rubart, Jessica
    Scatterplots are widespread mathematical diagrams visualizing data in usually two or three dimensions. In this paper, we present a prototypical app implemented for the Microsoft HoloLens 2 device, which demonstrates an immersive experience for multidimensional data. The data is visualized by a three-dimensional scatterplot using color for an optional fourth dimension. The immersive experience enables the manipulation of the dimensions as well as the interaction with the data elements. First user feedback indicates that in this way, users tend to get a better understanding of the underlying multidimensional data.

    Immersive Exploration of Machine Learning Data Combining Visual Analytics with Explainable AI
    (Mensch und Computer 2023 - Workshopband, 2023) Potthast, Jonas; Grimm, Valentin; Rubart, Jessica
    With the need to explain complex machine learning (ML) models it is necessary to explore human friendly visualizations and interaction techniques of data. In our position paper, we discuss a unique way for interacting with machine learning data to help decision makers in developing a mental model. This can increase trust towards the ML models and make the complexity digestible. In our approach, we combine visual analytics with explainable AI. In particular, we present a Mixed Reality based scatterplot application making use of SHAP values, where feature axes are automatically adjusted when diving deeper into parts of the data.
