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)
More and more industrial manufacturing companies are outsourcing assembly tasks to sheltered work organizations where cognitively impaired workers are employed. To facilitate these assembly tasks assistive systems have been introduced to provide cognitive assistance. While previous work found that these assistive systems have a great impact on the workers'(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)
Research on how to take advantage of Augmented Reality and Virtual Reality applications and technologies in the domain of manufacturing has brought forward a great number of concepts, prototypes, and working systems. Although comprehensive surveys have taken account of the state of the art, the design space of industrial augmented and virtual reality keeps(More)
Due to increasing complexity of products and the demographic change at manual assembly workplaces, interactive and context-aware instructions for assembling products are becoming more and more important. Over the last years, many systems using head-mounted displays (HMDs) and in-situ projection have been proposed. We are observing a trend in assistive(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)
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)
