    KiVR Sports: Influencing the Users Physical Activity in VR by using Audiovisual Stimuli in Exergames

    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.

    The Interactive Spatial Surface - Blended Interaction on a Stereoscopic Multi-Touch Surface
    (Mensch & Computer 2014 - Workshopband, 2014) Lubos, Paul; Garber, Carina; Hoffert, Anjuly; Reis, Ina; Steinicke, Frank
    Current touch technology provides precise and accurate large multi-touch surfaces, which allow multiple users to collaborate in these two-dimensional setups. Furthermore, recent developments in the field of display technology support visualization of three-dimensional (3D) virtual environments (VEs) in high-fidelity visual detail on these surfaces. Finally, cost-efficient depth cameras such as the Microsoft Kinect support affordable hand tracking, which enables interaction above the surface. In this paper we describe the interactive SPAtial SurfaCE (iSPACE), a system combining classical multi-touch-based interaction with direct mid-air selection and manipulation of stereoscopically projected virtual objects. By utilizing a large state-of-the-art Ultra HD 3D display and a high-performance touch frame, the system offers high-quality collaborative exploration.
