Conference Paper
Full-text available
Research on transparency tools for information privacy has largely focused on users’ perceptions of their usefulness—showing users prefer aggregated forms of data representation (e.g., interest segments) over hard-to-interpret raw data. However, users still do not understand what to learn from such interest segments. Representing a user’s digital f...

Deceptive patterns are often used in interface design to manipulate users into taking actions they would not otherwise take, such as consenting to excessive data collection. We present Trickery, a narrative serious game that incorporates seven gamified deceptive patterns. We designed the game as a potential mechanism for raising awareness of, and i...

User-centered evaluations are a core requirement in the development of new user related technologies. However, it is often difficult to recruit sufficient participants, especially if the target population is small, particularly busy, or in some way restricted in their mobility. We bypassed these problems by conducting studies on trade fairs that we...

Conference Paper
Full-text available
Despite the growth of physically assistive robotics (PAR) research over the last decade, nearly half of PAR user studies do not involve participants with the target disabilities. There are several reasons for this-recruitment challenges, small sample sizes, and transportation logistics-all influenced by systemic barriers that people with disabiliti...

In Human-Computer-Interaction, vibrotactile haptic feedback offers the advantage of being independent of any visual perception of the environment. Most importantly, the user's field of view is not obscured by user interface elements, and the visual sense is not unnecessarily strained. This is especially advantageous when the visual channel is alrea...

Mind-wandering, i.e., letting the mind drift away from the task at hand, is mostly seen as a state of mind to avoid, as it may negatively impact the current task. However, evidence in cognitive science shows that mind-wandering can also positively affect creativity and problem-solving. Still, there is a lack of technological solutions to facilitate...

Longitudinal studies in HCI research have the potential to increase our understanding of how human–technology interactions evolve over time. Potentially, longitudinal studies eliminate learning or novelty effects by considering change through repeated measurements of interaction and use. However, there seems to exist no agreement of how longitudina...
