Siyou Pei         


I'm a fifth year Ph.D. candidate, an AR/VR enthusiast, an HCI researcher @HiLab, Department of Electrical & Computer Engineering, UCLA, advised by Prof. Yang Zhang. I also had the fortune to work with mentors Alex Olwal, David Kim, and Ruofei Du. I will be interning at JPMC AR/VR Research Department this summer.
My research is about Extended Reality interaction with a focus on human body embodiment. Leveraging human expertise of their own body, I morph human body into virtual and physical objects to help users control objects intuitively. I also apply anthropomorphism to objects, utilizing common sense to help users easily understand smart environments.

I am on job market, open to opportunities in both academia and industry.


UI Mobility Control in XR: Switching UI Positionings between Static, Dynamic, and Self Entities

Siyou Pei, David Kim, Alex Olwal, Yang Zhang, and Ruofei Du (CHI '2024)
We facilitated UI mobility between static, dynamic, and self entities with Finger Switches based on users' in-situ needs.

WheelPose: Data Synthesis Techniques to Improve Pose Estimation Performance on Wheelchair Users

William Huang, Sam Ghahremani, Siyou Pei, and Yang Zhang (CHI '2024)
A data synthesis pipeline to address the underrepresentation of wheelchair users in data collection for pose estimation models.

Embodied Exploration: Facilitating Remote Accessibility Assessment for Wheelchair Users with Virtual Reality

Siyou Pei, Alexander Chen, Chen Chen, Franklin Mingzhe Li, Megan Fozzard, Hao-yun Chi, Nadir Weibel, Patrick Carrington, Yang Zhang (ASSETS '2023)
VR technique for wheelchair users to evalute accessibility remotely.

ForceSight: Non-Contact Force Sensing with Laser Speckle Imaging

Siyou Pei, Pradyumna Chari, Xue Wang, Xiaoying Yang, Achuta Kadambi, Yang Zhang (UIST '2022)
Best Demo Honorable Mention
Object surfaces deform in the presence of force. This deformation, though very minute, manifests as observable and discernible laser speckle shifts, which we leverage to sense the applied force.

Hand Interfaces: Using Hands to Imitate Objects in AR/VR for Expressive Interactions

Siyou Pei, Alexander Chen, Jaewook Lee, Yang Zhang (CHI '2022)
Best Paper Honorable Mention
A new interaction technique that lets users' hands become virtual objects by imitating the objects themselves. For example, a thumbs-up hand pose is used to mimic a joystick.

AURITUS: An Open-Source Optimization Toolkit for Training and Development of Human Movement Models and Filters Using Earables

Swapnil Sayan Saha, Mr. Sandeep Singh Sandha, Siyou Pei, Vivek Jain, Mr. Ziqi Wang, Yuchen Li, Ankur Sarker, Prof. Mani Srivastava (IMWUT '2021)
AURITUS is an extendable and open-source optimization toolkit designed to enhance and replicate earable applications, e.g., activity detection and head-pose tracking.
