Article
The opaque nature of many intelligent systems violates established usability principles and thus presents a challenge for human-computer interaction. Research in the field therefore highlights the need for transparency, scrutability, intelligibility, interpretability and explainability, among others. While all of these terms carry a vision of suppo...

Software that uses Artificial Intelligence technology like Machine Learning is becoming ubiquitous with even more applications ahead. Yet, the very nature of these systems has made it very hard to understand how they operate, creating a demand for explanations. While many approaches have been and are being developed, it remains unclear how strong t...
Conference Paper
Decision support systems based on AI are usually designed to generate complete outputs entirely automatically and to explain those to users. However, explanations, no matter how well designed, might not adequately address the output uncertainty of such systems in many applications. This is especially the case when the human-out-of-the-loop problem...
Conference Paper
Full-text available
Given the opaqueness and complexity of modern AI algorithms, there is currently a strong focus on developing transparent and explainable AI, especially in high-stakes domains. We claim that opaqueness and complexity are not the core issues for end users when interacting with AI. Instead, we propose that the output uncertainty inherent to AI systems...
Conference Paper
Software using Machine Learning algorithms is becoming ever more ubiquitous making it equally important to have good development processes and practices. Whether we can apply insights from software development research remains open though, since it is not yet clear, whether data-driven development has the same requirements as its traditional counte...

In the everyday context, e.g., a household, HMD users remain a part of the social life for Non-HMD users being co-located with them. Due to the social context situations arise that demand interaction between the HMD and the Non-HMD user. We focus on the challenge that the Non-HMD user is not able to interpret the HMD user's state -- e.g., attentive...
Preprint
A particular measure to evaluate a head-mounted display (HMD) based experience is the state of feeling present in virtual reality. Interruptions of a presence experience - break in presence (BIP) - appearing over time, need to be detected to assess and improve an application. Existing methods either lack in taking these BIPs into account - question...
