    3rdWorkshop on User-Embodied Interaction in Virtual Reality (UIVR)
    (Mensch und Computer 2021 - Workshopband, 2021) Roth, Daniel; Podkosova, Iana; Nilsson, Niels Christian; Kulik, Alexander; Bruder, Gerd
    The representation of users to others and themselves is especially important for Virtual/Mixed/Augmented Reality (VR/MR/AR) applications. The development of technological solutions and the understanding of underlying cognitive effects challenges humancomputer interaction (HCI) and related disciplines. A number of interesting research questions, such as realism of appearance and behavior as well as their effects on perception and user behavior arise, that are yet to be explored. To support a discussion and the generation of a common agenda, we will organize the 3rd half-day workshop on User-Embodied Interaction in VR (UIVR) gathering researchers and practitioners emphasizing the discussion of different positions on applications and findings to collect guidelines for future developments.

    Edutainment & Engagement at Exhibitions: A Case Study of Gamification in the Historic Hammaburg Model

    Gamification in the context of interactive exhibitions has enormous potential to attract visitors and improve their engagement, flow, and learning. This paper describes a case study in which we use game-design elements for an interactive and collaborative exploration of a virtual exhibition. The goal is to collaboratively explore the possibilities of a multiplayer game using different user interfaces and input devices in the same environment. The case study was conducted using a virtual 3D model of the “Hammaburg”, which is a medieval castle of the 9th century. The idea of the multiplayer exhibition consists of a two-player game. One player is using a touch-table or other touch input devices, whereas the other player is using an immersive head-mounted display (HMD), combined with a game controller to navigate through the virtual environment (VE). Both players can interactively explore the VE while playing a mini-game together. We performed a user study to evaluate the game concepts. The results suggest that communication between the players—both spoken and technologically supported—is a challenging task, and seems especially difficult for the HMD player. Furthermore, this paper proposes a more specific exploration of other possible settings focusing on the communication of the players.

    Evaluation von Buttons im Kontext des Gestaltungsstils Flat Design
    (Mensch und Computer 2015 – Proceedings, 2015) Lücken, Malte; Bruder, Gerd; Steinicke, Frank
    Bis vor wenigen Jahren waren viele Elemente grafischer Benutzerschnittstellen (engl. Graphical User Interfaces, GUI) durch realistische Gestaltungsmerkmale geprägt. Viele GUIs stellten beispielsweise dreidimensionale Buttons mit Schatten, Spiegelungen und Lichteffekten dar, ohne dass dies für deren Funktion notwendig gewesen wäre. Diesem so genannten Skeuomorphismus steht seit wenigen Jahren der Gestaltungsstil Flat Design gegenüber, bei dem GUI-Elemente ganz bewusst minimalistisch und ohne Bezug zu realen Vorbildern gestaltet werden. Im Rahmen einer Studie (N=332 Teilnehmer) wurden Eingabe-Buttons in verschiedenen Ausprägungen hinsichtlich der Auswahlhäufigkeit, Reaktionszeit und Präferenz untersucht. Die Ergebnisse zeigen, dass ein Mindestmaß an Affordanz (insbesondere ein Rahmen um die Buttonfläche) notwendig ist, sich die Performanz jedoch ansonsten zwischen den Ausprägungen und ihren Gestaltungsmerkmalen nicht signifikant unterscheidet.

    KiVR Sports: Influencing the Users Physical Activity in VR by using Audiovisual Stimuli in Exergames
    (Mensch und Computer 2019 - Tagungsband, 2019) Kirsch, Kolja; Schatzschneider, Christian; Garber, Carina; Rosenberger, Aila; Kirsten, Konya; Ariza, Oscar; Steinicke, Frank; Bruder, Gerd
    In traditional fitness or exercise situations, people often lack motivation. Fitness video games try to enhance exercise by combining cognitive game demands with physical activity and body coordination. Building on results of interdisciplinary game research, we designed and evaluated a dynamically-adaptive fitness game environment that has motivating effects and can be used besides, or as an alternative to standard fitness programs. In this work, we explore the effects of game design elements (e.g., music, lighting) on engagement in a VR exercise game suitable for HIIT (High-Intensity Interval Training). Participants reported a higher perceived incentive to perform well when the music tempo depended on the measured heart rate. A lower incentive was reported when the heart rate influenced in-game lighting. Static lighting produced significantly higher heart rate. Further displaying a score was effective on both heart rate and perceived incentive.

    Natural 3D Interaction Techniques for Locomotion with Modular Robots
    (Mensch und Computer 2015 – Proceedings, 2015) Krupke, Dennis; Lubos, Paul; Bruder, Gerd; Zhang, Jianwei; Steinicke, Frank
    Defining 3D movements of modular robots is a challenging task, which is usually addressed with computationally expensive algorithms that aim to create self-propelling locomotion. So far only few user interfaces exist which allow a user to naturally interact with a modular robot in real-time. In this paper we present two approaches for baseline research of 3D user interfaces for intuitive manipulation of 3D movements of a modular chain-like robot in the scope of an iterative design process. We present a comparative evaluation of the techniques, which shows that they can provide intuitive human-robot interaction via remote control for real-time guidance of modular robots to move through heavy terrains and pass obstacles. In particular, our results show that steering a robot’s locomotion via rotational hand movements has benefits for challenging locomotion tasks compared to translational hand movements. We discuss the results and present lessons learned for steering user interfaces for modular robots.

    smARTbox A Portable Setup for Intelligent Interactive Applications
    (Mensch & Computer 2012 – Workshopband: interaktiv informiert – allgegenwärtig und allumfassend!?, 2012) Fischbach, Martin; Wiebusch, Dennis; Latoschik, Marc Erich; Bruder, Gerd; Steinicke, Frank
    This paper presents a semi-immersive, multimodal fish tank simulation realized using the smARTbox, an out-of-the-box platform for intelligent interactive applications. The smARTbox provides portability, stereoscopic visualization, marker-less user tracking and direct interscopic touch input. Off-the-shelf hardware is combined with a state-of-the-art simulation platform to provide a powerful system environment. The environment combines direct (touch) and indirect (movement) interaction.

    User-embodied Interaction in Virtual Reality (UIVR)
    (Mensch und Computer 2019 - Workshopband, 2019) Roth, Daniel; Podkosova, Iana; Nilsson, Niels Christian; Kulik, Alexander; Bruder, Gerd
    The availability of tracking solutions allowing for the embodiment of users in Virtual- Mixed- and Augmented Reality (VR/MR/AR) applications challenges human-computer interaction (HCI) developers. Many potentials are yet to be explored. By no means is the most realistic replication of the user and the interaction a general optimum for all applications. In turn, altered body representations have perceptual impacts on the users themselves as well as on the perception of the interaction (“Kleider machen Leute”). To support a discussion and the generation of a common agenda, we will organize a half-day workshop on User-embodied Interaction in VR (UIVR) gathering researchers and practitioners emphasizing the discussion of different positions on applications and findings to collect guidelines for future developments.
