Designing for passengers' information needs on fellow travelers: A comparison of day and night rides in shared automated vehicles Appl. Ergon. (IF 3.2) Pub Date : 2023-12-12 Lukas A. Flohr, Martina Schuß, Dieter P. Wallach, Antonio Krüger, Andreas Riener
Shared automated mobility-on-demand promises efficient, sustainable, and flexible transportation. Nevertheless, security concerns, resilience, and their mutual influence – especially at night – will likely be the most critical barriers to public adoption since passengers have to share rides with strangers without a human driver on board. Prior research points out that having information about fellow

Thermoregulation of feet in cold environments: A study on alpinism Appl. Ergon. (IF 3.2) Pub Date : 2023-12-12 Eleonora Bianca, Francesca Dotti, Francesco Orrico, Ada Ferri
Thermal comfort plays a crucial role in the performance and well-being of mountaineers, especially in extreme environments. The aim of this study was to develop a reliable protocol to assess the thermal comfort of mountaineering boots, with a specific focus on temperature variations in different regions of the foot and their correlation with physiological factors. Two different models of mountaineering

Morphological analysis of the human earcanal deformations during face-related activities Appl. Ergon. (IF 3.2) Pub Date : 2023-12-08 Michel Demuynck, Aidin Delnavaz, Jérémie Voix
Ear-related technologies are spreading in our daily life and have become essential in several applications. The comfort, retention and battery life of in-ear devices can be substantially improved by considering the dynamic behavior of the earcanal. A better understanding of the earcanal dynamic motion would not only result in the improved fit and performance of earpieces but could also pave the way
