Adorned in Memes: Exploring the Adoption of Social Wearables in Nordic Student Culture
要旨

Social wearables promise to augment and enhance social interactions. However, despite two decades of HCI research on wearables, we are yet to see widespread adoption of social wearables into everyday life. More in-situ investigations into the social dynamics and cultural practices afforded by wearing interactive technology are needed to understand the drivers and barriers to adoption. To this end, we study social wearables in the context of Nordic student culture and the students’ practice of adorning boiler suits. Through a co-creation process, we designed Digi Merkki, a personalised interactive clothing patch. In a two-week elicitation diary study, we captured how 16 students adopted Digi Merkki into their social practices. We found that Digi Merkki afforded a variety of social interaction strategies, including sharing, spamming, and stealing pictures, which supported meaning-making and community-building. Based on our findings, we articulate “Memetic Expression” as a strong concept for designing social wearables.

Hitting Pause: How User Perceptions of Collaborative Playlists Evolved in the United States During the COVID-19 Pandemic
要旨

Through collaborative playlists (CPs), streaming platform users have co-curated music together for various purposes for over a decade. As the COVID-19 pandemic has transformed how people come together through technology and engage with music, CPs have also taken on new roles and value. To understand how CP usage and perception have evolved since the onset of COVID-19, we conducted a mixed-methods investigation of CPs in the United States. Survey results from primarily CP users (N=142) revealed that interest in and usage of CPs have mostly increased since the pandemic, and that the role of music in connecting with others is positively correlated with the perceived impact of COVID-19. Follow-up interviews (N=9) provided additional insights into changing perceptions and usage patterns of CPs during COVID-19; for instance, fewer collaborators per playlist reflects users’ greater focus on strengthening social connections and relationships. Taken together, findings and design implications on digitally mediated co-curation further elucidate the necessity for social and collaborative experiences with music supported by CPs during COVID-19.

BikeAR: Understanding Cyclists' Crossing Decision-Making at Uncontrolled Intersections using Augmented Reality
要旨

Cycling has become increasingly popular as a means of transportation. However, cyclists remain a highly vulnerable group of road users. According to accident reports, one of the most dangerous situations for cyclists are uncontrolled intersections, where cars approach from both directions. To address this issue and assist cyclists in crossing decision-making at uncontrolled intersections, we designed two visualizations that: (1) highlight occluded cars through an X-ray vision and (2) depict the remaining time the intersection is safe to cross via a Countdown. To investigate the efficiency of these visualizations, we proposed an Augmented Reality simulation as a novel evaluation method, in which the above visualizations are represented as AR, and conducted a controlled experiment with 24 participants indoors. We found that the X-ray ensures a fast selection of shorter gaps between cars, while the Countdown facilitates a feeling of safety and provides a better intersection overview.

Effects of Pedestrian Behavior, Time Pressure, and Repeated Exposure on Crossing Decisions in Front of Automated Vehicles Equipped with External Communication
要旨

Automated vehicles are expected to substitute driver-pedestrian communication via LED strips or displays. This communication is expected to improve trust and the crossing process in general. However, numerous factors such as other pedestrians' behavior, perceived time pressure, or previous experience influence crossing decisions. Therefore, we report the results of a triply subdivided Virtual Reality study (N=18) evaluating these. Results show that external communication was perceived as hedonically pleasing, increased perceived safety and trust, and also that pedestrians' behavior affected participants' behavior. A timer did not alter crossing behavior, however, repeated exposure increased trust and reduced crossing times, showing a habituation effect. Our work helps better to integrate research on external communication in ecologically valid settings.

FlexNav: Flexible Navigation and Exploration through Connected Runnable Zones
要旨

Runners want to actively explore unknown environments without the fear of getting lost. We conducted a survey to better understand runners’ needs and practices in this context. The survey results emphasized the interest in flexible exploration. To address this interest, we designed FlexNav, a system that supports exploratory running through flexible tours that link the best runnable zones in a neighbourhood. FlexNav provides adaptive navigation support enabling runners to follow such tours without continually getting disruptive directions. We tested it with runners to assess its usability. The results confirm the usefulness of the system and the users' preference for flexible tours over fully specified tours with turn-by-turn guidance. Our study highlights the subjective nature of runnable zones and the subtle balance between guidance and exploration.
