From Toil to Thought: Designing for Strategic Exploration and Responsible AI in Systematic Literature Reviews

Systematic Literature Reviews (SLRs) are fundamental to scientific progress, yet the process is hindered by a fragmented tool ecosystem that imposes a high cognitive load. This friction suppresses the iterative, exploratory nature of scholarly work. To investigate these challenges, we conducted an exploratory design s…

DensityBars: A Space-Efficient Visualization for Event Temporal Distribution

Event temporal distribution analysis aims to capture both global (e.g., rises and peaks) and local patterns (e.g., frequent occurrences and sudden absences). Traditional charts typically rely on adjusting binning granularities to reveal such patterns. However, this strategy forces a trade-off between global clarity an…

Cluster-Based Approach for Visual Anomaly Detection in Multivariate Welding Process Data Supported by User Guidance

Welding robots are essential in modern manufacturing as they automate hazardous welding tasks, improving productivity and safety while reducing costs. However, a significant portion of the total part costs comes from the manual visual inspection and the rework of robot-welded seams, underlining the importance of proce…

CreAItive Collaboration? Users' Misjudgment of AI-Creativity Affects Their Collaborative Performance

How does generative AI affect collaborative creative work and humans' capability to carry it out? We tested 52 participant pairs in a standard creativity test, the Alternate Uses Test. The experimental AI group had access to ChatGPT-4, while the control group did not. The intervention did not lead to an improved pe…

Does the Medium Matter? An Exploration of Voice-Interaction for Self-Explanations

This research evaluates voice-based self-explanations as a pedagogical tool in preparation for lectures, assesses user preferences between voice and text, and derives design insights. We report two studies: Study 1, a quasi-experimental field study, with 247 participants divided into voice-based (N=83), text-based (N=…

Flicker Augmentations: Rapid Brightness Modulation for Real-World Visual Guidance using Augmented Reality

Providing attention guidance, such as assisting in search tasks, is a prominent use for Augmented Reality. Typically, this is achieved by graphically overlaying geometrical shapes such as arrows. However, providing visual guidance can cause side effects such as attention tunnelling or scene occlusions, and introduce…

An Asymmetric Multiplayer Learning Environment for Room-Scale Virtual Reality and a Handheld Device

Many different digital learning environments are currently in use. In combination with virtual reality (VR) technologies, these allow the creation of engaging hands-on experiences. While VR environments can deeply immerse the person wearing the headset, spectators are often not actively involved or are not even consid…

Eye-Perspective View Management for Optical See-Through Head-Mounted Displays

Optical see-through (OST) head-mounted displays (HMDs) enable users to experience Augmented Reality (AR) support in the form of helpful real-world annotations. Unfortunately, the blend of the environment with virtual augmentations due to semitransparent OST displays often deteriorates the contrast and legibility of an…

Territoriality in Hybrid Collaboration

Hybrid Collaboration, where remote and co-located team members work together using different devices and tools, has already been trending in recent years (e.g., through globalization and international cooperation) but experienced a further boost since the outbreak of the COVID-19 pandemic. The reason behind this surge…

TiiS: Humanized Recommender Systems: State-of-the-Art and Research Issues
