With the opportunity to customize ordered products, assembly tasks are becoming more and more complex. To meet these increased demands, a variety of interactive instruction systems have been introduced. Although these systems may have a big impact on overall efficiency and cost of the manufacturing process, it has been difficult to optimize them in a(More)
With increasing complexity of assembly tasks and an increasing number of product variants, instruction systems providing cognitive support at the workplace are becoming more important. Different instruction systems for the workplace provide instructions on phones, tablets, and head-mounted displays (HMDs). Recently, many systems using in-situ projection for(More)
Routing has an important influence on the performance of interconnection networks in parallel computers. Besides simple oblivious schemes like xy-routing for 2D grids there exist a lot of sophisticated adaptive and fault-tolerant routing algorithms which could however not be implemented so far, because there are no fast hardware routers which are able to(More)
Interactive tabletops or projections became widely utilized in schools, museum exhibitions or conference rooms to teach and illustrate dynamic artifacts or support talks. In such scenarios, all observers, such as pupils and teachers, will perceive the same information even if they hold different positions and could benefit from an adapted and personalized(More)
Human vision underlies natural constraints. Field of view, perceived wavelength, angular resolution, or perspective are just a few. Combining a head-mounted display with a camera can overcome some of these limitations and constraints. We investigate the field of view, which is created by presenting a third person view to the wearer of the head-mounted(More)
Magnetocardiography provides touchless information about myocardial excitation propagation and repolarization. This evolving diagnostic technique has been used so far to risk-stratify patients in terms of sudden cardiac death and to detect myocardial ischemia. We evaluated its potential to assess myocardial viability in patients with coronary artery(More)
With increasingly large smartphones, it becomes more difficult to use these devices one-handed. Due to a large touchscreen, users can not reach across the whole screen using their thumb. In this paper, we investigate approaches to move the screen content in order to increase the reachability during one-handed use of large smartphones. In a first study, we(More)
As Brain-Computer Interfaces become available to the consumer market, this provides more opportunities in analyzing brain activity in response to different external stimuli. Current output modalities often generate a lot data, such as an electroencephalogram which only displays electrode measurements. We introduce a three-dimensional real-time brain data(More)
Head-mounted displays for virtual reality (VR) provide high-fidelity visual and auditory experiences. Other modalities are currently less supported. Current commercial devices typically deliver tactile feedback through controllers the user holds in the hands. Since both hands get occupied and tactile feedback can only be provided at a single position,(More)
