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)
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)
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)
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)
Projectors most likely will be embedded into the next generation of mobile devices, and thus projecting pictures and videos into the physical world will be an important use case. However, the projection positioning in the real world is challenged by surface reflections or objects in the environment. As adjusting the projected image manually is cumbersome,(More)
The way human perceive their environment depends strongly on the senses they have. One of them is the natural first person view using their eyes, which is limited regarding the field of view, perceived wavelengths or angular resolution. A third person view, which is often used in video games to provide a better visibility of the avatar and its surroundings,(More)
