Conversational agents (CAs) that deliver proactive interventions can benefit users by reducing their cognitive workload and improving performance. However, little is known regarding how such interventions would impact users’ reflection on choices in voice-only decision-making tasks. We conducted a within-subjects experiment to evaluate the effect o...

To design user-centered services, it is essential to build empathy toward users. It is hence strategic to trigger empathy for users among professionals concerned with shaping service user experiences. There is, however, a lack of quantitative tools to measure empathy in design. Through two studies, we report on the development and validation of the...

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 collaborati...

HCI researchers are increasingly concerned about the prevalence of manipulative design strategies in user interfaces, commonly referred to as "dark patterns". The line between manipulation and persuasion strategies is often blurred, leading to legal and ethical concerns. This paper examines the tension between persuasive UX practices and manipulati...

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...

Technology ethics is increasingly at the forefront of human-computer interaction scholarship, with increasing visibility not only to end users of technology, but also regulators, technology practitioners, and platforms. The notion of "dark patterns" has emerged as one common framing of technology manipulation, describing instances where psychologic...

App permission requests are a control mechanism meant to help users oversee and safeguard access to data and resources on their smartphones. To decide whether to accept or deny such requests and make this consent valid, users need to understand the underlying reasons and judge the relevance of disclosing data in line with their own use of an app. T...

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...

Research in HCI and design position empathy as a key factor of a successful user-centred approach, supported by the emergence of empathic design methods. However, there is a dearth of empathy measurement tools to investigate the actual ability of design methods to trigger empathy among designers and beyond within the organization. For service stake...

Designers incorporate values in the design process that raise risks for vulnerable groups. Persuasion in user interfaces can quickly turn into manipulation and become potentially harmful for those groups in the realm of intellectual disabilities, class, or health, requiring proactive responsibility approaches in design. Here we introduce the Capabi...

A cookie banner pops up when a user visits a website for the first time, requesting consent to the use of cookies and other trackers for a variety of purposes. Unlike prior work that has focused on evaluating the user interface (UI) design of cookie banners, this paper presents an in-depth analysis of what cookie banners say to users to get their c...

Online services pervasively employ manipulative designs (i.e., dark patterns) to influence users to purchase goods and subscriptions, spend more time on-site, or mindlessly accept the harvesting of their personal data. To protect users from the lure of such designs, we asked: are users aware of the presence of dark patterns? If so, are they able to...

This position paper draws from the complexity of dark patterns to develop arguments for differentiated interventions. We propose a matrix of interventions with a measure axis (from user-directed to environment-directed) and a scope axis (from general to specific). We furthermore discuss a set of interventions situated in different fields of the int...

Chatbots have been adopted in the health domain and their number grew during the current COVID-19 pandemic. As a new kind of interface, chatbots combine visual elements with natural conversation. While conversational capabilities of chatbots improve, little attention has been given to the evaluation of the user experience and chatbot usability. Thi...

Experience has become the new paradigm of product design. Designers seek to anticipate emotions or associations a user might have when in contact with their design. The factors that influence human product perception are diverse. We firstly show which product dimensions are currently investigated by design researchers. It becomes obvious that besid...

Over the last decade, User Experience (UX) has become a core concept in the field of Human-Computer Interaction (HCI). Beyond the fact of understanding and assessing the User Experience derived from the use of interactive systems, practitioners and researchers from a wide range of disciplines are now facing the challenges of designing for User Expe...

International audience The UX domain has so far been strongly associated with software development. However, its methods are finding their way intodomains like Product and Service Design. Product Designers now need competencies far beyond classical form-giving. The objective of thispaper is to show Product Designers which design dimensions they nee...

The Japanese culture is known for its excellent service and hospitality which is based on the philosophy of Motenashi. This paper shows how aspects of Japanese hospitality can be applied to Interaction Design to enrich the sensual value of product interfaces. The analysis of Motenashi was undergone with literature on Japanese culture, guided interv...
