At Fraunhofer IPT we are realizing industry 4.0 through the adaptive digitalization and networking of machines, parts, personnel and other entities in the working environment, in order that information and instruction will be available everywhere and all the time in the production process. With analysis of big production data including machine states and product information gathered in the manufacturing, a predictive production process will be possible, which leads to the reduction of raw materials and scrap parts and to shorten the makespan. In addition, smart devices will play a very important role to help people being integrated in the future manufacturing environment. In this paper, we present our current development progress within the from the German Research Foundation DFG supported Cluster of Excellence “Integrative Production Technology for High-Wage Countries”. Firstly, an overall introduction to our current research in industry 4.0 research is given. After that we propose a conception of implementing digitalization and connection, which presents the effort to enhance both the ability of workers and human-machine-interaction in future production environment. Furthermore, we discuss the application areas of wearable computer technology and identify research topics for smart glasses. With a demonstrator developed in this scope for visual inspection of working parts we present the agile and flexible retrievability of information and interactivity of smart glasses in the future working environment. A further work area in our scope of Industry 4.0 development is the tracing & tracking of participating entities, i.e. the Internet-of-Things (IoT). We are now working on a Bluetooth-based agile low-cost Indoor Positioning System, which will also be proposed in this paper.
