The way we experience time is based on its psychological value. Time spent efficiently or pleasantly positively influences the time experience. When choosing a transportation mode, people highly value flexibility, reliability, and autonomy. Public ...

While the web offers a great potential to find and share information, the cognitively demanding conditions of online interactions can leave users vulnerable to cognitive biases, such as the confirmation bias – the tendency to favor information that ...

The presented doctoral research aims to develop a behavioural user profiling framework focusing simultaneously on three beyond-accuracy perspectives: privacy, to study how to intervene on graph data structures of specific contexts and provide methods to ...

When faced with a difficult situation, searching for emotional support is one of the most natural things to do. Being supported not only helps regulating the negative emotions, but it also promotes coping skills and psychological adjustment to stressful ...

The role of credibility in persuasive systems is undoubted. It is therefore important that the determinants of credibility are clearly understood. Studies have asserted that personalizing persuasive principles, for instance, based on users’ personality, ...

Organizations, friends, family members, etc., construct groups and conduct discussions to make decisions about the problems. Group decision-making is a complicated and time-consuming process since the group members involved in a discussion may have ...

Intelligent personal assistants (IPAs) have become widely available, yet they remain primarily used for discrete, straightforward tasks. By contrast, both user studies and literature reviews indicate that IPAs of the future are to be personalised, ...

Adaptive information access systems is one of the most popular types of adaptive systems. It includes adaptive search, recommender system, adaptive navigation support, and adaptive information visualization. This is also one of the oldest types of ...

Ethical considerations are getting increased attention with regards to providing responsible personalization for robots and autonomous systems. This is partly a result of the currently limited deployment of such systems in human support and interaction ...

Argumentation schemes are generalised patterns that provide a way to (partially) dissociate the content from the reasoning structure of the argument. On the other hand, Cialdini’s principles of persuasion provide a generic model to analyse the ...

The availability of low-cost wireless physiological sensors has allowed the use of emotion recognition technologies in various applications. In this work, we describe a technique to predict emotional states in Russell’s two-dimensional emotion space (...

Theory-based, or “white-box,” models come with a major benefit that makes them appealing for deployment in user modeling: their parameters are interpretable. However, most theory-based models have been developed in controlled settings, in which ...

People with Dementia (PwD) and their caregivers can greatly benefit from regular cognitive and social activations. However, these activations need to be engaging and likeable to take effect and to maintain long-term motivation and wellbeing. Taking this ...

For many blind users, interaction with computer applications using screen reader assistive technology is a frustrating and time-consuming affair, mostly due to the complexity and heterogeneity of applications’ user interfaces. An interview study ...

Video viewing is an important component of online learning, yet little is known about what information about learning outcomes can be derived from students’ video control actions. We investigate the extent to which information on student learning is ...

Applications designed for entertainment and other non-instrumental purposes are challenging to optimize because the relationships between system parameters and user experience can be unclear. Ideally, we would crowdsource these design questions, but ...

Persuasive conversations are more effective when they are custom-tailored for the intended audience. Current persuasive dialogue systems rely heavily on advice-giving or focus on different framing policies in a constrained and less dynamic/flexible ...

Food recommender systems show personalized recipes to users based on content liked previously. Despite their potential, often recommended (popular) recipes in previous studies have turned out to be unhealthy, negatively contributing to prevalent obesity ...

Advances in artificial intelligence and machine learning have led to a steep rise in the adoption of AI to augment or support human decision-making across domains. There has been an increasing body of work addressing the benefits of model ...

The search engine of music streaming platforms is a high-control method for navigating the catalog. If one is to study users’ search behavior in this context, one can leverage the vast body of research on general information behavior while challenging ...
