So bezeichnet Intrapreneurship das Vorgehen, Angestellte innerhalb von Unternehmen selbst als Unternehmerinnen und Unternehmer agieren zu lassen, um so Innovation zu f{\"o}rdern. Der Begriff Design Thinking beschreibt ein Vorgehen, mit Hilfe dessen uneindeutig definierte Probleme behandelt und nutzerzentrierte Produkte entwickelt werden k{\"o}nnen. Die Pr{\"a}misse dieses Beitrags ist es, dass die Kombination von neuartigen Technologien und besonders Virtual Reality mit Design Thinking den Innovationsprozess innerhalb von Unternehmen f{\"o}rdern kann. Anhand zweier Fallbeispiele wird dargestellt, dass neben Nachteilen technischer Natur besonders die M{\"o}glichkeit fiktive Szenarien in VR darzustellen und valide Nutzerdaten in labor{\"a}hnlichen Verh{\"a}ltnissen zu sammeln, Innovation in Unternehmen anregen kann. In weiteren Schritten soll die Nutzung von Design Thinking und Virtual Reality in neuen Applikationsdom{\"a}nen sowie die Nutzung weiterer Designmethoden untersucht werden.}, language = {en} } @inproceedings{StadlerBraunFrenkler, author = {Stadler, Sebastian and Braun, Carmen and Frenkler, Fritz}, title = {The Usage of Mixed Reality for Presentations: A Comparative Evaluation}, series = {XR and Metaverse : Proceedings of the 8th International XR-Metaverse Conference 2023, Las Vegas, USA}, booktitle = {XR and Metaverse : Proceedings of the 8th International XR-Metaverse Conference 2023, Las Vegas, USA}, editor = {Dieck, M.

Electrochemical-energy storage reaches higher capacities at smaller costs, but at the expense of efficiency. This pattern continues in a similar way for chemical-energy storage. In terms of capacities, the limits of batteries (accumulators) are reached when low-loss long-term storage is of need. Chemical-energy storage and stocking fulfills these requirements completely. The storing itself may be subject to significant efficiency losses, but, from today's point of view and in combination with the existing gas and fuel infrastructure, it is the only national option with regards to the long-term storage of renewable energies. Chemical-energy storage is the backbone of today's conventional energy supply. Solid (wood and coal), liquid (mineral oil), and gaseous (natural gas) energy carriers are 'energy storages' themselves, and are stored using different technologies. In the course of energy transition, chemical-energy storage will be of significant importance, mainly as long-term storage for the power sector, but also in the form of combustibles and fuels for transport and heat. Not only are conventional storing technologies discussed within this chapter, but a detailed explanation is also given about the storage of renewable energies in the form of gaseous (power-to-gas, PtG) and liquid (power-to-liquid, PtL) energy carriers for electricity, heat, chemicals, and in the form of synthetic fuels.}, language = {en} } @incollection{SternerBauerCrotoginoetal., author = {Sterner, Michael and Bauer, Franz and Crotogino, Fritz and Eckert, Fabian and von Olshausen, Christian and Teichmann, Daniel and Thema, Martin}, title = {Chemische Energiespeicher}, series = {Energiespeicher - Bedarf, Technologien, Integration}, booktitle = {Energiespeicher - Bedarf, Technologien, Integration}, edition = {2.

The results show that the HMI concepts help passengers to reduce anxiety in the AV. Overall, VR turned out to be a suitable tool for this exploratory study. Further work will focus on testing HMI concepts in a variety of more complex scenarios to ensure user acceptance.}, language = {en} }
