I am a PhD student at Electrical and Computer Engineering, University of California, Los Angeles (UCLA), advised by Prof. Yang Zhang. Currently, my research is centered on harnessing the kinetic energy generated by people interactions with everyday objects to smarten up the environment by facilitating activity recognition and home automation. I am also broadly interested in the application of radar technologies in IoT, energy harvesting, ubiquitous sensing, wireless power transfer and wearable sensing.

Research & Projects
Headar: Sensing Head Gestures for Confirmation Dialogs on Smartwatches with Wearable Millimeter-Wave Radar (IMWUT 2023)
Xiaoying Yang, Xue Wang, Gaofeng Dong, Zihan Yan, Mani Srivastava, Eiji Hayashi, Yang Zhang
Headar employs mmWave radar to detect head gestures, enabling fluent and natural interaction through nods and shakes between user and wearable devices.
CubeSense++: Smart Environment Sensing with Interaction-Powered Corner Reflector Mechanisms (UIST 2023)
Xiaoying Yang, Jacob Sayono, Yang Zhang
CubeSense++ are battery-free reflector mechanisms that can encode user interactions with everyday objects into structured responses to mmWave radar.
MiniKers: Interaction-Powered Smart Environment Automation (IMWUT 2022)
Xiaoying Yang, Jacob Sayono, Jess Xu, Jiahao "Nick" Li, Josiah Hester, Yang Zhang
MiniKers is a fleet of environment actuation devices that harness energy from user interactions with everyday objects. "Kers" comes from "Kinetic Energy Recovery System" that are widely used in automotive systems for recovering energy under braking.
ForceSight: Non-Contact Force Sensing with Laser Speckle Imaging (UIST 2022)
Siyou Pei, Pradyumna Chari, Xue Wang, Xiaoying Yang, Achuta Kadambi, Yang Zhang
ForceSight is a non-contact force sensing approach using laser speckle imaging. Surface deformations caused by force can be approximated by laser speckle shift.
CubeSense: Wireless, Battery-Free Interactivity through Low-Cost Corner Reflector Mechanisms (CHI 2021 LBW)
Xiaoying Yang, Yang Zhang
CubeSense is a sensing approach that encodes user interactivity (e.g. button press, switch toggle, slider position, knob rotation) into Radar Cross Section (RCS) of corner reflectors.
