Hi, I am Yujie.

I am a master's student at University of Chicago, working on human-computer interaction, wearables and haptics. My interests lie in creating novel interactive devices and understanding how they can improve people's wellbeing. I am a member of Human Computer Integration Lab, advised by Prof. Pedro Lopes. During the summer, I work with Prof. Tanzeem Choudhury's group at Cornell Tech.

I received my bachelor's degree from UNC-Chapel Hill with a double major in Computer Science and Journalism. Before jumping into HCI research, I had experience in product management and marketing, where I explored areas such as social networks, cybersecurity, and health advertising.

In Proceedings of ISMAR 2020

We leveraged higher-level Purkinje images to improve eye tracking accuracy for both vergence and accommodation. In this work, I designed and fabricated a user-customized eyetracker prototype suited for eyeglasses-style AR and VR displays. I also collected and analyzed Purkinje image data with OpenCV.
