    An Active Tangible Device for Multitouch-Display Interaction
    (Mensch und Computer 2019 - Tagungsband, 2019) Brauer, Christoph; Ariza, Oscar; Steinicke, Frank
    In this article, we introduce an interactive tangible input device (TID) for touchscreens. Our approach complements a passive TID design by active microcontroller-driven features focusing on user-experience aspects. The TID provides battery-powered wireless operation, autonomous position sensing capabilities, visual and tactile feedback as well as multiple touch inputs and momentary buttons. The device can be accurately tracked in capacitive touchscreens, enabling novel interaction techniques for content selection and manipulation in 2D or stereoscopic tabletop environments, mid-air interaction is also supported by the use of IMU and short-to-mid-range distance sensors. Overall, we present a multi-purpose device which can be built using off-the-shelf-components, features a seamless firmware integration, Unity3D integration, and a 3D-printable body enclosure.

    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.

    A VR Study on Freehand vs. Widgets for 3D Manipulation Tasks
    (Mensch und Computer 2019 - Tagungsband, 2019) Schlünsen, Robin; Ariza, Oscar; Steinicke, Frank
    We present in this article the results of a study based on a hand-based 3D UI toolkit we developed which can be easily adapted and reused in VR applications with hand-tracking. We evaluated hand-based and widget-based manipulation methods as well as different multimodal cues for 3D manipulation and system-control tasks. Our study compared the manipulation methods in terms of performance, accuracy, and user acceptance. We found that free-hand manipulation is faster and preferred by the participants. We also analyzed the influence of the multimodal cues, finding valuable insights to integrate these cues to improve the user experience and accuracy in a 3D manipulation task.
