1. RecalibrateGPT: AI Fatigue Resilient Conversational Interfaces

They found: Two pilot studies with 12 advanced LLM users report roughly halved perceived workload and high usability, suggesting that conversation operations can reduce fatigue beyond model-quality gains.

2. Are We There Yet? Assessing Computer-Use Agents for Blind Users' Accessible Interaction with Desktop Applications

They found: Eight blind participants issued 1,258 commands across 12 applications; GPT-5 achieved the highest reported success rate at 52.5%, with failures spanning grounding, planning, constraint tracking, and termination.

3. Designing Proactive Thought Partners for Writing

They found: Sixteen participants used the probe for one week and valued planned roles, timely initiative, lightweight visual representations, and non-directive framing.

4. Better Situational Awareness in AR-HRC? A Comparative Study of Augmented Reality and Mobile Interfaces for Human-Robot Collaboration

They found: AR improved perception-level awareness of the robot but did not improve higher-level robot or environmental awareness; freed attention was redirected to conformal visuals rather than the physical scene.

5. Evaluating Usability in Biomedical Visualization: Rethinking Heuristic Evaluation for Spatial Omics and Multidisciplinary Research Platforms

They found: Across 39 participants, complex overlays, unlabeled tools, and immediate feature density caused trial-and-error behavior; the authors propose parameter transparency, point-of-use guidance, and phased disclosure.
