Indeed, ensuring safety for users is essential for the future commercial launch of this technology. Within this study, human-machine interfaces (HMIs) are evaluated regarding the communication between autonomous vehicles (AVs) and pedestrians in order to prepare a successful deployment of the technology on the market. Since real-life experiments involving AVs remain dangerous, experiments were conducted via virtual reality (VR). The results show that beyond the need for HMIs, display-based concepts were more usable than laser projections. The study impacts on: 1) substantiating the need for explicit HMIs on AVs (including concept recommendations) for a successful market entry; 2) proving that VR constitutes an advantageous alternative for conducting experiments in the field of autonomous transportation for both research and business. Further work is needed that involves more participants and an improved virtual environment.}, language = {en} } @article{StadlerCornetFrenkler, author = {Stadler, Sebastian and Cornet, Henriette and Frenkler, Fritz}, title = {Assessing Heuristic Evaluation in Immersive Virtual Reality: A Case Study on Future Guidance Systems}, series = {Multimodal Technologies and Interaction}, volume = {7}, journal = {Multimodal Technologies and Interaction}, number = {2}, issn = {2414-4088}, doi = {10.3390/mti7020019}, pages = {19}, abstract = {A variety of evaluation methods for user interfaces (UI) exist such as usability testing, cognitive walkthrough, and heuristic evaluation. However, UIs such as guidance systems at transit hubs must be evaluated in their intended application field to allow the effective and valid identification of usability flaws. However, what if evaluations are not feasible in real environments, or laboratorial conditions cannot be ensured? Based on adapted heuristics, in the present study, the method of heuristic evaluation is combined with immersive Virtual Reality (VR) for the identification of usability flaws of dynamic guidance systems (DGS) at transit hubs. The study involved usability evaluations of nine DGS concepts using the newly proposed method. The results show that compared to computer-based heuristic evaluations, the use of immersive VR led to the identification of an increased amount of "severe" usability flaws as well as overall usability flaws. Within a qualitative assessment, immersive VR is validated as a suitable tool for conducting heuristic evaluations involving significant advantages such as the creation of realistic experiences in laboratorial conditions. Future work seeks to further prove the suitability of using immersive VR for heuristic evaluations and compare the proposed method to other evaluative methods.}, language = {en} } @article{CornetStadlerKongetal., author = {Cornet, Henriette and Stadler, Sebastian and Kong, Penny and Marinkovic, Goran and Frenkler, Fritz and Sathikh, Peer Mohideen}, title = {User-centred design of autonomous mobility for public transportation in Singapore}, series = {Transportation Research Procedia}, volume = {41}, journal = {Transportation Research Procedia}, publisher = {Elsevier}, address = {Amsterdam}, issn = {2352-1465}, doi = {10.1016/j.trpro.2019.09.038}, pages = {191 -- 203}, abstract = {The paper presents a set of methods for user-centred design of autonomous mobility for public transportation in the context of a multi-disciplinary research programme in Singapore, called TUMCREATE. While traffic engineers plan the operation of the new mobility system, the Industrial Designers of TUMCREATE take on the role of designing the autonomous vehicles (AVs) and infrastructure for greater comfort and a positive travel experience for users. Tasks have been identified to promote user acceptance and facilitate the operation of autonomously driven vehicles for public transport. To fulfil these tasks, conventional design methods have been enhanced with Virtual Reality (VR) technology and with simulations developed by the computer scientists of TUMCREATE. Since public transportation is a complex and broad area, it cannot be investigated with a single design method. First results showed that conventional methods that consider the Universal Design principles guarantee the accessibility, usability and understandability of AVs and stations. VR has been identified as a suitable tool for Industrial Designers to evaluate communication concepts between AVs and pedestrians. This confirms that digital tools (i.e. VR) enhance conventional design methods, especially with regard to technologies that are not available on the market yet (e.g. AVs)}, language = {en} } @article{KongStadlerForchhammeretal., author = {Kong, Penny and Stadler, Sebastian and Forchhammer, Niklas and Cornet, Henriette}, title = {Menschzentrierte Gestaltung f{\"u}r ein autonomes Mobilit{\"a}tssystem in Singapur}, series = {ATZextra}, volume = {25}, journal = {ATZextra}, number = {Suppl 1}, publisher = {Springer Fachmedien}, address = {Wiesbaden}, issn = {2509-4610}, doi = {10.1007/s35778-020-0112-5}, pages = {38 -- 43}, abstract = {Die Automatisierung macht auch vor den {\"o}ffentlichen Verkehrsmitteln nicht halt.
