Am Standort Brugg/Windisch betreibt die FHNW ein Maker Studio mit einem Schaufenster zur Präsentation von Wechselausstellungen. Um Passanten in die Wechselausstellungen einbeziehen zu können, sind lichtempfindliche Schalter am Schaufenster angebracht, mit denen die interaktiven Elemente einer Ausstellung gesteuert werden können. Diese Schalter und anderen interaktiven Elemente sind mit Technologien des Internet of Things (IoT) realisiert worden. Unter IoT wird die virtuelle Repräsentation realer, physischer Objekte verstanden, die untereinander mithilfe der Internet-Technologien kommunizieren können.

In this publication1 we present a generic design for a novel annular barcode. On round media, circular or annular barcodes are more natural and preferable instead of traditional rectangular barcodes. Especially on round media with a distinctly convex or concave conic surface, an annular barcode is even more preferable than a full circle, because printing the barcode in the center of the media might be much more complicated or imprecise. Our generic annular barcode design supports different barcode and module sizes and therefore different data sizes. It includes different marker, synchronization, and data areas. For improved data robustness a data protocol and error correcting codes similar to them in QR codes are suggested. The feasibility of the design is shown by an implementation of an efficient and effective barcode decoder in C++ and a series of tests with distorted and noisy pictures of our annular barcodes.

In the project „Active Data Logger“ we investigate the design of embedded data acquisition systems when focusing on mobility, efficiency and coverage of as many use cases as possible. Mobile data acquisition systems are needed in many fields of research and productive environments that require mobility, and they have different requirements than non-mobile data acquisition systems. After all, data collection and analysis is a very important task, as it provides a basis for gaining knowledge and taking decisions based on the results. The feasibility of a universal mobile data acquisition system is demonstrated with a proof of concept design and implementation which covers multiple use cases.
