Workplace health interventions have predominantly been designed around visualizations of physical activity data in the work routine. Yet, contextual factors, such as computer-based activity, appears to be crucial to support healthier behaviors at work. In this research, we explore the effect of visualizing computer-based activity to prompt physical activity at work, through desktop-based ambient displays. Based on our prototypes Yamin and Apphia, we conducted an exploratory qualitative user study in a lab setting with office workers (N=16). Results showed that visualizing one’s computer-based activity could potentially increase the awareness, self-reflection, and social interactions for individuals to become physically active. With our findings, we discuss design implications for using computer activity data in a physical form as a motivational factor to encourage physically active workstyles. We present directions for future field studies to gain further insights on this topic. [less ▲]

This paper describes Ivy, an office chair that represents sitting time of an office worker through growing ivy strands. The longer one sits, the more strands will grow onto the chair. By means of a qualitative interface called Ivy, we illustrate a design approach that is currently underrepresented in sedentary behavior interventions. With this approach, we counter the current trend of digitalization and quantification of health interventions. Instead of graphs and numbers, Ivy uses data physicalization as a qualitative interface that represents sitting. We describe the design, the process, and future research steps of Ivy as a critical perspective on sedentary behavior interventions. We aim to spark discussion amongst designers and researchers in the field of Human-Computer Interaction to use qualitative interfaces as a promising approach to deepen the user's relationship with the targeted behavior and enrich the ability to construct meaning from the feedback. © 2020 Owner/Author.

The office jungle: A vision for wildness to turn offices into jungles

The Office Jungle is an experimental office environment designed to make offices more "wild". Through this demonstration and associated design vision, we make a first attempt to reflect on and to define what characterizes wildness and how it could empower people in more playful and active lifestyles, particularly in the workplace. In our understanding, wildness is not an exclusive property of nature, but rather a condition that can be designed for. How wildness can be designed is described here in a set of design principles called "Design for Wildness", inspired by the work of Gibson. The Office Jungle, a large geodesic sphere of 2 meters in diameter, is part and parcel of these design principles and can be used as a tool to design other wild environments. Such environments could benefit people working in the office, many of whom have been suffering the consequences of a sedentary lifestyle. © 2020 Owner/Author. [less ▲]

Runner's Perceptions of Reasons to Quit Running: Influence of Gender, Age and Running-Related Characteristics.

Physical inactivity has become a major public health concern and, consequently, the awareness of striving for a healthy lifestyle has increased. As a result, the popularity of recreational sports, such as running, has increased. Running is known for its low threshold to start and its attractiveness for a heterogeneous group of people. Yet, one can still observe high drop-out rates among (novice) runners. To understand the reasons for drop-out as perceived by runners, we investigate potential reasons to quit running among short distance runners (5 km and 10 km) (n = 898). Data used in this study were drawn from the standardized online Eindhoven Running Survey 2016 (ERS16). Binary logistic regressions were used to investigate the relation between reasons to quit running and different variables like socio-demographic variables, running habits and attitudes, interests, and opinions (AIOs) on running. Our results indicate that, not only people of different gender and age show significant differences in perceived reasons to quit running, also running habits, (e.g., running context and frequency) and AIOs are related to perceived reasons to quit running too. With insights into these related variables, potential drop-out reasons could help health professionals in understanding and lowering drop-out rates among recreational runners. [less ▲]

Running is a popular recreational sport, yet for many amateur runners it remains challenging to turn intentions into sustainable running behavior. Although the market offers a myriad of running-related devices that aim to motivate runners, these often focus on the training itself and not on overcoming the barriers experienced prior to the run. A better understanding of these barriers to running is essential to identify design opportunities for technologies supporting amateur runners. We conducted two complementary studies among participants of a women-only running event. Combining an online survey (N = 114) and a journey mapping activity (N = 13), we investigated the influence of motivational barriers and enablers in runners' rituals. Based on our findings, we created the Runner's Journey, a visual narrative highlighting actionable design opportunities for running motivation technology. We propose five design recommendations to overcome barriers among amateur runners. © 2020 ACM. [less ▲]

How Acceptable Is This? How User Experience Factors Can Broaden our Understanding of the Acceptance of Privacy Trade-Offs

Privacy is a timely topic that is increasingly scrutinized in the public eye. In spite of privacy and security breaches, people still frequently compromise their privacy in exchange for certain benefits of a technology or a service. This study builds on both technology acceptance (TA) and user experience (UX) research in order to explore and build hypotheses regarding additional dimensions that might play a role in the acceptability of privacy tradeoffs that are not currently accounted for in TA models. Using four scenarios describing situations with potential privacy trade-offs, we conducted a focus group study with 8 groups of participants (N = 32). Our results suggest that factors influencing privacy trade-offs go beyond existing TA factors alone. A technology's perceived usefulness plays an important role, as well as dimensions related to context, previous experiences, perceived autonomy and the feeling of control over the data being shared.

This paper presents a mobile application for vote-casting and vote-verification based on the Selene e-voting protocol and explains how it was developed and implemented using the User Experience Design process. The resulting interface was tested with 38 participants, and user experience data was collected via questionnaires and semi-structured interviews on user experience and perceived security. Results concerning the impact of displaying security mechanisms on UX were presented in a complementary paper. Here we expand on this analysis by studying the mental models revealed during the interviews and compare them with theoretical security notions. Finally, we propose a list of improvements for designs of future voting protocols. [less ▲]

The present study reports on the user experience (UX) of rich-prospect browsing, an emerging interface design trend for digital cultural heritage. Building on research that suggests online museum collections are used only infrequently by the general public, this study investigates the role of next-generation user interfaces in the design of optimal browsing experiences. Moreover, it describes the results of user testing for three different arts and culture collections that make use of rich-prospect. The study recruited 30 participants of varying ages, nationalities, and museum visiting habits to discuss their museum experiences and test three different applications: Coins, Curator Table, and Museum of the World. The results of the study provide insights into the user experience of a new browsing medium and reveal the information-seeking habits and patterns that occurred within these information environments. Moreover, the study isolated the core features of rich-prospect in order to define opportunities and pain points during the browsing experience and indicated which features in particular are most important to people during the browsing experience. Finally, we suggest some best practices going forward in the design of rich-prospect. [less ▲]
