Mobile apps are a success story for mobile devices, particularly in the consumer sector. Tailored to a specific task, they offer optimal usability for a defined class of devices. However, today's apps are neither designed to collaborate with complex workflows nor to support these. To overcome this limitation, we developed the concept of Mobile App(More)
This paper presents a mobile assistance system for service and maintenance personnel in industrial facilities. It provides an innovative interaction metaphor designed to fit domain specific working conditions. As a result of a strictly user-centered design process, the presented system follows the principles of <i>Embodied Interaction</i>. The system is(More)
This paper demonstrates a lightweight and highly decentralized collaboration infrastructure approach for virtual enterprises and describes its added-value in the customer-oriented production domain. First, we will describe challenges and key requirements of an exemplary application scenario. Second, we are going to present the reference architecture and(More)
In a globalised world the process industry faces great challenges regarding data management. Rising demands for agility and rapid shortening of innovation cycles have lead to project-based collaborations. Highly specialised small and medium enterprises are forming so-called virtual companies to profit from each other. Today, however, industrial data(More)
Future Internet Networked Enterprise Systems demand enhanced collaboration and mobility support. FI technologies are fundamental for increased service differentiation and cost optimisation in manufacturing environments. However, such ICT-based capabilities are not easy to introduce, in particular to SMEs, due to high costs and complexity. To progress in(More)
This position paper argues for adapting the Apps-approach to industrial interactive Linked Data applications (iLD) and presents a design study for a small application that is applicable whenever an information foraging task at hand may be described as carefully examining the neighborhood of a concept. This little App is primarily being developed for(More)
As Smart Manufacturing, Industrial Internet, Industrie 4.0, and Cyber-Physical Production System (CPPS) are becoming reality, the way process and manufacturing plants are operated has to change. Additionally, these developments - constituting the pervasive digitalisation of industry - have a profound effect on the way human workers and machines interact.(More)
