The year 2020 was dominated by the Corona pandemic, which abruptly changed everyday life at the university. Bonn-Rhein-Sieg University of Applied Sciences (H-BRS) succeeded not only in maintaining operations under these difficult circumstances, but also in enriching them with new ideas and insights. This difficult year 2020 has opened up new perspectives, especially for teaching, but also for research and administration. This annual report, to which we have given the motto "Walking - knowing the point of view, taking direction, showing attitude", tells of this. It shows which paths the H-BRS has taken in the past year. Some routes were rocky, and some slopes could only be overcome with combined efforts. Often, however, new terrain was opened up. The aim was always to find answers to the multi-layered, complex questions of our time - whether with regard to digitalisation, climate change or the social responsibility of science.
Change - shaping reality
(2019)
We present a novel forearm-and-glove tactile interface that can enhance 3D interaction by guiding hand motor planning and coordination. In particular, we aim to improve hand motion and pose actions related to selection and manipulation tasks. Through our user studies, we illustrate how tactile patterns can guide the user, by triggering hand pose and motion changes, for example to grasp (select) and manipulate (move) an object. We discuss the potential and limitations of the interface, and outline future work.
In presence of conflicting or ambiguous visual cues in complex scenes, performing 3D selection and manipulation tasks can be challenging. To improve motor planning and coordination, we explore audio-tactile cues to inform the user about the presence of objects in hand proximity, e.g., to avoid unwanted object penetrations. We do so through a novel glove-based tactile interface, enhanced by audio cues. Through two user studies, we illustrate that proximity guidance cues improve spatial awareness, hand motions, and collision avoidance behaviors, and show how proximity cues in combination with collision and friction cues can significantly improve performance.
