MiniKers: Interaction-Powered Smart Environment Automation (IMWUT 2022)
"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)
CubeSense: Wireless, Battery-Free Interactivity through Low-Cost Corner Reflector Mechanisms (CHI 2021 LBW)
CubeSense is a wireless, battery-free and low-cost sensing system based on corner reflector mechanisms. We designed several controllers by encoding user interactivity (e.g. button press, switch toggle, slider position, knob rotation) into Radar Cross Section (RCS) of corner reflectors.
