User acceptance is required for the successful introduction of this technology. One essential prerequisite for acceptance is appropriately trusting the vehicle’s capabilities. System transparency via visualizing internal information could calibrate this trust by enabling the surveillance of the vehicle’s detection and prediction capabilities, including its failures. Additionally, concurrently increased situation awareness could improve take-overs in case of emergency. This work reports the results of two online comparative video-based studies on visualizing prediction and maneuver-planning information. Effects on trust, cognitive load, and situation awareness were measured using a simulation (N=280) and state-of-the-art road user prediction and maneuver planning on a pre-recorded real-world video using a real prototype (N=238). Results show that color conveys uncertainty best, that the planned trajectory increased trust, and that the visualization of other predicted trajectories improved perceived safety}, year = {2023}, month = {12}, DOI = {10.1145/3631408}, journal = {Proceedings of the ACM on Interactive, Mobile, Wearable and Ubiquitous Technologies (IMWUT)}, publisher = {ACM}, address = {New York, NY, USA}, pages = {23}, file_url = {t3://file?uid=483418} } @Article { 548473804178_2023, author = {Rixen, Jan Ole and Meinhardt, Luca-Maxim and Gl\"{o}ckler, Michael and Schlothauer, Anna and Ziegenbein, Marius-Lukas and Colley, Mark and Gugenheimer, Jan and Rukzio, Enrico}, title = {The Loop and Ways to Break It: Investigating Infinite Scrolling Behaviour in Social Media Applications and Reasons to Stop}, status = {1}, year = {2023}, month = {09}, DOI = {10.1145/3604275}, journal = {Proceedings of the 25th International Conference on Mobile Human-Computer Interaction (MobileHCI '23) (conditionally accepted}, publisher = {ACM}, keywords = {rixen2023loop}, file_url = {t3://file?uid=481676} } @Conference { rixen2023dissonance, author = {Rixen, Jan Ole and Funk, Christian and Rukzio, Enrico and Gugenheimer, Jan}, title = {May I Still Define Myself? Exploring How Dissonance in Displaying Personal Information Through Head-Mounted Augmented Reality Can Affect Personal Information Sovereignty}, abstract = {Head-mounted Augmented Reality enables individuals to overlay digital information onto the physical world, consequently influencing how they assess and react to augmented social situations. While prior work has shown that augmenting social situations with faithful personal information can benefit a conversation, honest mistakes or an attempt to deceive might lead to a dissonance between augmentation and verbally disclosed information. In this work, we take the first steps towards understanding the happenings in case of information dissonance by conducting a preliminary within-subject online video study (N=30), investigating how it affects users, perception of the interlocutor, and if augmentation or interlocutor would act as the more trusted instance. We found that only 26.7{\%} trusted the interlocutor’s verbally uttered information, while a majority believed the AR device (46.7{\%}) or were undecided (26.7{\%}).

Most current interaction approaches rely either on additional hardware (e.g. Daydream Controller) or offer only a limited interaction concept (e.g. Google Cardboard). We explore a solution where a conventional smartwatch, a device users already carry around with them, is used to enable short interactions but also allows for longer complex interactions with mobile VR. To explore the possibilities of a smartwatch for interaction, we conducted a user study in which we compared two variables with regard to user performance: interaction method (touchscreen vs inertial sensors) and wearing method (hand-held vs wrist-worn). We found that selection time and error rate were lowest when holding the smartwatch in one hand using its inertial sensors for interaction (hand-held).}, year = {2018}, month = {4}, DOI = {10.1145/3170427.3188629}, organization = {In Proceedings of CHI EA '18 (CHI '18 Extended Abstracts on Human Factors in Computing Systems)}, keywords = {3D pointing; smartwatch; nomadic virtual reality; mobile virtual reality}, file_url = {t3://file?uid=435518} }
