Greetings! 👋

I'm Peiyu Zhang

HCI Researcher and Software Engineer at UVA

I am a Systems and Information Engineering PhD candidate at the University of Virginia, advised by Prof. Sara Riggs. I am passionate about designing interfaces and systems that empower users to better harness emerging technologies such as AI and mixed reality. My research interests include human factors, multi-display interfaces in mixed reality, human-AI collaboration, and tangible interaction.

My Research

Multitasking Across Physical and Virtual Displays: The Effect of Spatial Discontinuity and Task Load

In submission to IEEE VR 26

Peiyu Zhang, Mohamad El Iskandarani, Sara Riggs
User study examining how the use of AR, spatial discontinuity between displays, and task load affect multitasking performance and perceived workload.

The Effect of Layout on Visual Search in Augmented Reality Multi-Window Displays

Accepted by IEEE TVCG

Peiyu Zhang, Mohamad El Iskandarani, Sara Riggs
User study examining how the spatial placement of multi-display AR, in relation to depth separation, information density, and the curvature of virtual multi-window displays, affects visual search performance.

The Effect of AI Assistance Timing on Performance and User Perceptions in Pathological Slide Diagnosis

Elsevier Applied Ergonomics

Peiyu Zhang, Zichen Ye, Ronggan Wei, Haiyan Niu, Hongxia Li, Mingjuan Wang, Peng Xue, and Sara Lu Riggs,
User study evaluating how the timing of AI-provided information affects clinicians' performance, workload, and trust and percieved usability of the AI tool.
