We present Moirai, a device that aids runners in self-regulating their running routine. By negotiating with the device, runners can balance their desire to achieve their goals while preventing overtraining injuries. The interaction relies on the strategic repertoire principle, a five-way taxonomy of strategies used in human- human negotiation. The user and the system can use the following strategies: contending, conceding, compromising, problem-solving, and avoiding. Behavior change design predominantly focuses on the first two: contending relates to hard paternalism, where the user has no choice but to accept, and conceding to soft paternalism or nudging, where the user can deviate from a default. The other three strategies are relatively underexplored, the closest to some of these being the aesthetic of friction. Relying on data and human negotiation strategies to reach a goal that is not solely one of the users, Moirai can appear as a moral agent. We envision these principles as applicable beyond the exercising context to other domains that require self-regulation, such as health, sustainability, or productivity- related applications.

While working on a computer typically involves sitting for prolonged periods of time, sedentary work routines are associated with numerous health issues. To address this societal concern, existing solutions trigger physical activity as a break from work, rather than a part of it. In this research, we explore a vision for physically active ways of working, by transforming mundane digital tasks into physically active ones. As a research artifact and design exemplar, we present A2-I2, an innovative tangible system for sending emails. After loading their email onto a physical “letter” token, office workers must walk to a physical mailbox located in the office space. Understanding what design qualities influence the experience and acceptability of such systems is a necessary step toward the design of acceptably active interface interactions. We report on a preliminary user test with 8 participants. With this project, we aim to inspire future tangible and embodied systems addressing the timely issue of sedentary behavior at work.

As the workplace collaboration software market is booming, there is an opportunity to design tools to support reflection and self-regulation of collaboration practices. Building on approaches from personal informatics (PI), we aim to understand and promote the use of data to enable employees to explore their work practices, specifically collaboration. Focused on the preparation stage of PI (deciding to track and tools selection), we invited office workers (N=15, knowledge workers in academia) to identify meaningful aspects of their collaboration experience and report them in a logbook for two weeks. We then conducted semi-structured interviews with participants to identify and reflect on metrics related to collaboration experience. We contribute new insights into employees’ motivations and envisioned metrics reflecting their collaboration, including the personal, social, and organizational considerations for collecting and sharing this data. We derive design implications for self-tracking technologies for collaboration. [less ▲]

Uncovering factors influencing railway passenger experiences through love and breakup declarations

While existing approaches for assessing passenger experience are often limited to surveys of customer satisfaction, societal and technological challenges push the railway industry to adopt a user-centric approach to the design of their service. We used the love and breakup method in a study involving N = 53 passengers making a declaration to their railway company to collect qualitative feedback on the passenger experience. The method allowed to gather personal, emotional, and contextual insights into passengers’ experiences that can inform the transportation service design process. We describe 21 factors and 8 needs influencing the passenger experience, thereby consolidating and deepening prior work in the railway context. Using the lens of user experience theories, we argue that the service should be assessed against fulfilling these needs, which can act as guiding principles regarding service improvement. The study also presents valuable insights into the love and breakup method to explore service experiences. [less ▲]

DISCOV: Stimulating Physical Activity through an Explorative Interactive Walking Experience

Aware of the consequences of their inactive lifestyles, many people still struggle to integrate enough physical activity into their busy lives. Interventions that nudge to reinforce existing active behavior seem therefore more likely to be effective than those adding an activity to daily routines. To encourage people to increase their physical activity level, we designed Discov, a network of physical waypoints triggering people to lengthen their walks. Placed in a public park, Discov encourages people to explore their surroundings in a fun and challenging way by creating an interactive walking experience. Adopting a Research-through-Design approach, we explore the potential of the design of accessible infrastructures and human-environment interactions to impact public health by nudging citizens into being more physically active. We discuss insights gathered through this process and report on first user tests of this interactive walking experience. [less ▲]

Urban planning and design offer opportunities to nudge people towards more active behavior. This is a popular topic among urbanists and health professionals, with several guidelines and best practices already developed. However, a gap exists between theory and practice and the complex realization process of such active environments is rarely documented. In this study, we investigated the process of designing, implementing, and evaluating active urban environments through semi-structured interviews with 11 European practitioner experts in the field of active environment design and development. We additionally analyzed 51 examples of active environments they provided. We discuss definitions of active environments and their added value to encourage active behavior and provide an overview of the spectrum of design strategies, elements and boundaries used to create them. We also describe typical steps in the design and realization process, including types of stakeholders, main gaps, and points of friction in this practice [less ▲]

Research in human–computer interaction (HCI) has identified meaning as an important, yet poorly understood concept in interaction design contexts. Central to this development is the increasing emphasis on designing products and technologies that promote leisure, personal fulfillment, and well-being. As spaces of profound historical significance and societal value, museums offer a unique perspective on how people construct meaning during their interactions in museum spaces and with collections, which may help to deepen notions of the content of meaningful interaction and support innovative design for cultural heritage contexts. The present work reports on the results of two studies that investigate meaning-making in museums. The first is an experience narrative study (N = 32) that analyzed 175 memorable museum visits, resulting in the establishment of 23 triggers that inform meaningful interaction in museums. A second study (N = 354) validated the comprehensiveness and generalisability of the triggers by asking participants to apply them to their own memorable museum experiences. We conclude with a framework of meaning in museums featuring the 23 triggers and two descriptive categories of temporality and scope. Our findings contribute to meaning research in HCI for museums through an articulation of the content of meaning-making in the cultural sector. [less ▲]

Empathy towards users is crucial to the design of user-centered technologies and services. Previous research focused on defining empathy and its role in the design process for triggering empathy for end-users. However, there is a lack of empathy measurement instruments in design. Most previous work focused on designers, overlooking the need for other stakeholders to develop empathy towards the users to break organizational silos and deliver high-quality user-centered services and products. In this contribution, we share the preliminary stages of the development of an empathy scale for service design. We build on empathy literature from psychology and design to define 18 items representing four empathy dimensions. We report on the definition of these dimensions and their underlying items, and present preliminary studies in which we reviewed the first version of the scale with experts and stakeholders. [less ▲]
