Effective narrative visualization communicates information by integrating story-telling and data visualization in a comprehensible, compelling manner. The compelling aspect of effective narrative visualization consequentially results in the potential to ...

In this paper we describe NudgeRank^TM, an innovative digital algorithmic nudging system designed to foster positive health behaviors on a population-wide scale. Utilizing a novel combination of Graph Neural Networks augmented with an extensible Knowledge ...

When people use web search engines to find information on debated topics, the search results they encounter can influence opinion formation and practical decision-making with potentially far-reaching consequences for the individual and society. However, ...

In this work, we investigate the efficacy of boost interventions rooted in information literacy principles to enhance user interaction with search results and promote knowledge acquisition on debated topics. We conducted a pre-registered online user ...

Exhibiting altruism toward and cooperativeness with others is a key ingredient for successful work relationships and managerial decision making. Rising political polarization creates a hazard because it ruptures this fabric and impedes the interaction of ...

Prior research found that a significant portion of EU-based websites responded to the GDPR by implementing privacy dialogs that contained inadequate consent options or dark patterns nudging visitors towards accepting tracking. Less attention, so far, ...

The use of technology to combat online misinformation is becoming a prominent topic of research and practice, yet most of the existing solutions do not consider the impact of cognitive biases in misinformation-related decision-making. Addressing this ...

Social networks, especially on mobile interfaces, can potentially undermine users’ digital wellbeing promoting passive and excessive use. Previous attempts to support users’ self-control either focus on restricting use, e.g., through usage timers and ...

Agents often exert influence when interacting with humans and non-human agents. However, the ethical status of such influence is often unclear. In this paper, we present the SHAPE framework, which lists reasons why influence may be unethical. We ...

As web designers may deliberately adopt design patterns to hook users’ attention, researchers and practitioners have innovated several tools for supporting users’ digital self-control, hoping to help users self-regulate technology use – especially ...

Healthcare providers have long grappled with patients not showing up for their scheduled medical appointments; such no-shows lead to wasted resources and longer wait times for other patients. However, new operations research offers a promising solution to ...

Patient no-shows for scheduled medical appointments are of great concern for many healthcare providers. In this paper, we tackle the no-show problem by applying insights from behavioral science. Specifically, we “nudge” patients into arriving for their ...

People make a vast number of decisions every day and these decisions invoke either a reflective or automatic behavior. Using e.g., nudging to influence a person’s behavior in a positive direction can have beneficial sustainable effects. This study aims ...

How could an envisioned voice-based conversational information system assist the information seeker when the seeker does not know how to continue the conversation? The system could explicitly suggest a question to ask after each of its responses, but ...

Besides technological innovations in energy production and management technologies, the fight against climate change requires fundamental changes in our energy consumption behavior. Behavioral interventions are key to this process, especially when ...

Self-assembling team formation systems, where online users can select their teammates, are gaining research and industry interest. Still, the benefits of diversity remain frequently untapped for these teams, as people tend to choose others similar to ...

This paper revisits concepts of nudge in the context of helping consumers to make healthier food choices. We introduce a novel form of social influence nudge not yet investigated by HCI scholars, the out-group social comparison, and test whether this ...

We develop an algorithm based on the nudging data assimilation scheme for the concurrent (on-the-fly) estimation of scalar parameters for a system of evolutionary dissipative partial differential equations in which the state is partially observed. The ...

Dark patterns are user interface elements that can influence a person's behavior against their intentions or best interests. Prior work identified these patterns in websites and mobile apps, but little is known about how the design of platforms might ...

Data protection regulatory policies, such as the European Union's General Data Protection Regulation (GDPR), force website operators to request users' consent before collecting any personal information revealed through their web browsing. Website ...

While nudging is a long-established instrument in many contexts, it has more recently emerged to be relevant in cybersecurity as well. For instance, existing research suggests nudges for stronger passwords or safe WiFi connections. However, those ...
