Your stomach knows best?Gruden, Timotej (Avtor) Jakus, Grega (Avtor) Sodnik, Jaka (Avtor) Stojmenova Pečečnik, Kristina (Avtor) electrogastrographycomfortautomated drivinguser interfacedriving simulatorIn this paper, we present a novel approach of assessment of user interfaces, designed to positively affect passenger comfort, using electrogastrography (EGG). EGG is a method that records electrical activity of the stomach, and has been shown to reliably assess motion sickness, which is one of the main contributors to physical discomfort in AVs. A user study with 26 (22 complete data sets for analysis) participants was conducted in a driving simulator, assessing three types of auditory-tactile user interfaces (UI) (baseline, abstract, representational) for highly automated driving using EGG features such as dominant fre-quency, tachygastria, and crest factor of spectral density. The results indicate that the percentage of power spectrum density in the tachygastric range increased when using an abstract UI during events requiring lateral AV maneuvers. These findings suggest that EGG can serve as an objective method for evaluating passenger-centric interfaces in future vehicles.20262026-10-05 13:24:52Neznano189400UDK: 629.33-52:004.8ISSN pri članku: 2168-4081DOI: 10.1145/3828158.3838259COBISS_ID: 293692419OceCobissID: 293651203sl
