While prior research focused on increasing the use of ESFs through behavior change interventions, there is currently no clarity on the barriers that restrict their utilization in the first place. To bridge this gap, we conducted a qualitative analysis of 349 Amazon product reviews and 98 Reddit discussions, yielding three qualitative themes that showcase how users perceive, interact with, and evaluate ESFs in HAs. Based on these themes, we derived frequent barriers to ESF adoption, which guided a subsequent expert focus group (N=5) to assess the suitability of behavior change interventions and potential alternative strategies for ESF adoption. Our findings deepen the understanding of everyday barriers surrounding ESFs and enable the targeted design and assessment of interventions for future HAs.}, year = {2024}, month = {Mar}, DOI = {10.1145/3643558}, journal = {Proc.

While prior work dominantly focuses on exploring performances of augmentations, this work aims to understand the societal impact of AR in complex social situations. Focusing on prosocial helping behaviour, we created two scenarios and designed five augmentations aiming to motivate a user to help. We wanted to understand (1) the impact on situation perception and (2) the impact on the social structure. In an online video experiment (n=294), we found that augmenting can impact anxiety about the situation and significantly increase the perceived reason to help being directed towards the augmentation. Similarly, we found that the helped rated the \dqreason\dq and \dqthankfulness\dq significantly higher towards AR than the helper, creating a disagreement around agency and responsibility. We discuss the implications of AR in complex social structures and how responsibility and agency will become important when embedding AR in our social lives.}, year = {2023}, month = {12}, day = {03}, reviewed = {1}, DOI = {10.1145/3626705.3627969}, journal = {Proceedings of the 22nd International Conference on Mobile and Ubiquitous Multimedia}, publisher = {ACM}, address = {New York, NY, United States}, file_url = {t3://file?uid=485402} } @Article { 727349643249_2023, author = {Colley, Mark and Speidel, Oliver and Strohbeck, Jan and Rixen, Jan Ole and Belz, Jan Henry and Rukzio, Enrico}, title = {Effects of Uncertain Trajectory Prediction Visualization in Highly Automated Vehicles on Trust, Situation Awareness, and Cognitive Load}, abstract = {Automated vehicles are expected to improve safety, mobility, and inclusion. 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).

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} }
