About Me

Hi! I’m a PhD student in Computer Science at the Hong Kong University of Science and Technology, advised by Prof. Huamin Qu at VisLab. My research focuses on creating AI-Powered interactive systems to enhance visual accessibility for blind and low vision users. I’m also broadly interested in augmenting human abilities for diverse populations.

Before my PhD studies, I earned both my bachelor’s and master’s degrees from Tsinghua University, including an M.S. in Computer Science (advised by Prof. Yuanchun Shi), a B.E. in Electrical Engineering, and a second B.A. in Digital Meida Art. I also spent two years working as a software product manager at Xiaomi Corporation.

Research Overview

As a systems researcher in Human-Computer Interaction, I create AI-powered interactive systems that enhance visual accessibility and augment human abilities in three core areas:

1. Multi-Modal AI Systems for Accessible Visual Media: I build multi-modal machine learning pipelines that enable BLV users to engage with various forms of visual media, such as online video comments (CHI 2025, best paper honorable mention), 360° videos (UIST 2025), and personal photo collections (UIST 2024). These systems empower BLV users to enjoy visual content more deeply and immersively.

2. Multi-Sensory Interfaces for Real-World Navigation: I develop wearable systems that leverage multi-sensory feedback—such as on-body haptics (IMWUT 2020), handheld vibrations (CHI 2021), and head-mounted light cues (IMWUT 2021)—to support navigation for BLV users. These interfaces help users follow paths smoothly and accurately in real-world environments.

3. AI-Powered Interactive Learning Support: Beyond visual accessibility, I explore how human-AI systems can enhance self-directed learning and problem-solving for broader populations. Two collaborative projects will appear at the UIST 2025 full paper track.

Game Projects

Beyond my research, I design indie games that encourage players to explore new knowledge, reflect on social issues, and reimagine how we engage with the digital world. These projects include:
