Furthermore, mass customization and the increasing usage of AI even in manual assembly offers new opportunities as well as it creates new challenges. OBJECTIVE:The trend towards mass customization in turn leads to increased complexity in production, which results in additional mental workload. This effect will continue in the foreseeable future. METHOD:Especially for small and medium sized companies, the backbone of Germany’s economy, automatization and Human-Robot-Collaboration will take time to develop. Information assistance systems are and will be a bridging technology to help organizations to manage increasing complexity and the mental workload of their employees to not only boost productivity but also keep their workforce healthy. The ongoing demographic change further underlines the need to use information assistance systems to compensate possible age-associated deficits, but also keep older employees committed to their work and avoid effects of disengagement or disenfranchisement through participatory ergonomics. RESULTS: Information assistance systems can only develop their inherent potential if they are designed to support employees of varying age, competence levels, and affinity for technology. Participatory development and early engagement are key factors for an increased acceptance and usage of the systems as well as the individualization to make it suitable for each individual employee. CONCLUSION:Expanding the functionalities to an adaptive assistance system, using physiological correlates of mental workload as an input, is conceivable in the future. }}, author = {{Bläsing, Dominic and Hinrichsen, Sven and Wurm, Susanne and Bornewasser, Manfred}}, booktitle = {{Work}}, issn = {{1875-9270 }}, keywords = {{Cognitive ergonomics, aging workforce, complexity, mixed-model assembly}}, number = {{4}}, pages = {{1535--1548}}, publisher = {{IOS Press}}, title = {{{Information assistance systems as preventive mediators between increasing customization and mental workload}}}, doi = {{http://doi.org/10.3233/WOR-211283}}, volume = {{72}}, year = {{2022}}, } @misc{8824, author = {{Müller, Dustin}}, keywords = {{Metaverse, Digitalisierung, Virtual Reality, Augmented Reality}}, pages = {{43}}, publisher = {{Technische Hochschule Ostwestfalen-Lippe}}, title = {{{Metaverse - wie sich die Welt digital und virtuell verändert (Chancen und Risiken des Metaverse)}}}, year = {{2022}}, } @misc{9162, abstract = {{The German manufacturing industry has been carrying out new developments towards the next industrial revolution, focusing on smart manufacturing environments.

Both perspectives have their right and need to go hand in hand. The first four of the twelve chapters contributed by leading experts in the fi eld address the theoretical foundations. The individual authors' views sometimes complement each other, sometimes they express similar ideas and concepts, and sometimes they even contradict each other severely. Since we are currently far from having established a common ground about what this emerging genre clearly defi nes and separates from related fields, we suggest treating the individual chapters with equal respect and being prepared to contribute to the fi eld with one's own thoughts and ideas that might help further shape and clarify the important issues of Pervasive Games.}}, author = {{Magerkurth, Carsten and Röcker, Carsten}}, booktitle = {{A reader for pervasive gaming research ; Vol. 1., Concepts and technologies for pervasive games }}, isbn = {{978-3-8322-6223-5}}, keywords = {{Pervasive Gaming Applications, User Interfaces, Smart Home Environments, Mixed Reality}}, publisher = {{Shaker}}, title = {{{Towards the Emergence of a New Application Domain}}}, volume = {{5-9}}, year = {{2007}}, } @inbook{4771, abstract = {{Pervasive Games have become popular in recent years.

Now, we apply these foundations to real Pervasive Games and explore the issues related to actually realizing such Pervasive Games. Clearly, the combination of virtual, physical, and social aspects in Pervasive Gaming contributes to a new complexity in game design, since games are no longer confi ned to the narrowness of a computer screen, but integrate with our real environments that consist of many things beyond our control.}}, author = {{Magerkurth, Carsten and Röcker, Carsten}}, booktitle = {{A reader for pervasive gaming research / Vol. 2.
