    Computerspiele zum Anfassen ein digital-analoger Baukasten für Brettspiel
    (Mensch & Computer 2013 - Workshopband, 2013) Krause, Robin; Haase, Marcel; Hatscher, Benjamin; Herzog, Michael A.; Goutrié, Christine
    Die Idee hinter DiTAG, dem »Digital To Analog Gaming Board«, ist ein modulares Interface zum Entwickeln und Spielen von Brettspielen, das die Lücke zwischen digitaler und analoger Spielwelt schließt. Das Spielbrett besteht aus einzelnen Bausteinen, die sich mittels Steckverbindungen zusammenfügen lassen und mit einem RFID-Lesegerät sowie einem Transponder ausgestattet sind. Jedes Modul kann so angrenzende Bausteine oder die auf ihm platzierten Spieleobjekte erkennen. Das Baukastenprinzip erlaubt es den Spielern eigene Spielideen zu entwickeln und jedes beliebige Objekt zur Spielfigur oder Karte zu machen. Die technologische wie gestalterische Herausforderung des Projektes ergibt sich aus dem Wechselspiel analoger und digitaler Spielelemente. Der präsentierte Prototyp dient in diesem Sinne als Labor, in dem neue Spielformate und damit einhergehende Interaktions- und Gestaltungskonzepte in der Anwendungsumgebung entwickelt und getestet werden.

    Foot Interaction Concepts to Support Radiological Interventions
    (i-com: Vol. 17, No. 1, 2018) Hatscher, Benjamin; Luz, Maria; Hansen, Christian
    During neuroradiological interventions, physicians need to interact with medical image data, which cannot be done while the hands are occupied. We propose foot input concepts with one degree of freedom, which matches a common interaction task in the operating room. We conducted a study to compare our concepts in regards to task completion time, subjective workload and user experience. Relative input performed significantly better than absolute or rate-based input. Our findings may enable more effective computer interactions in the operating room and similar domains where the hands are not available.

    Influence of augmented reality interaction on a primary task for the medical domain
    (Mensch und Computer 2019 - Workshopband, 2019) Solovjova, Alina; Hatscher, Benjamin; Hansen, Christian
    Augmented reality can deliver valuable information right where the user needs it. When used to display complex data, interaction is required to access all the information. For general use-cases, hand gestures are the go-to technique to interact in augmented reality contexts. However, in some usecases, the hands are not always available for interaction. For instance, in the operating room, it is likely that the surgeon needs to perform a primary task with the hands simultaneously. This work investigates the influence of interaction tasks using head & hand, head & foot and head & speech on a primary task and the suitability of these input modalities for two kinds of interaction tasks. Results show that interaction techniques used in a multitasking environment should always be evaluated together with a primary task as it might cause user preferences to shift.

    Plantar pressure-based gestures for medical image manipulation
    (Mensch und Computer 2018 - Tagungsband, 2018) Solovjova, Alina; Labsch, Dominic; Hatscher, Benjamin; Fritzsche, Markus; Hansen, Christian
    In this work, we present an interaction concept for manipulating an image viewer only using a pressure sensitive shoe insole. A simple foot gesture set has been created and applied to a prototypical user interface, which enables the changing of slices of medical image data in an image viewer. In a pilot study, the gestures were tested according to the NASA Task Load Index (NASA-TLX). The purpose of this project was to estimate how suitable and user-friendly different foot gestures are in practice. We found that plantar pressure-based gestures are quite intuitive and users quickly become accustomed to using them. However, gestures based on overlapping pressure-sensitive areas might lead to unintended results.
