This is an IEEE paper I co-authored around a fairly specific question: when two people work together in augmented reality, does showing someone their own gaze, on top of their partner's, actually help? We built a collocated sorting task in Unity for pairs of HoloLens 2 users and compared showing just the partner's gaze against showing both. I built the task and ran it as a proper user study under IRB approval. The short answer is that self-gaze isn't always needed, but it made people more confident in some collocated settings.
In the Ruiz HCI Lab at UF I build the software behind human-subjects research, eye-tracking, augmented reality, and how people trust and use AI. That runs from real-time gaze pipelines to full study apps with IRB-compliant data collection, and into the analysis afterward. I like research questions you can only really answer by building the thing a person then sits down and uses.
