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. ...

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 ...

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 ...
