Selected Research

  • RFID Tattoo: A Wireless Platform for Speech Recognition

    Three million people in the US are suffering voice impairments. Current solutions, like keyboard and electrolarynx, require extra effort for the patients to compensate for their voice disorders. We present RFTattoo, an elegant speech recognition system for voice impaired using batteryless and flexible RFID tattoos.

  • Pushing the Range Limits of Commercial Passive RFIDs

    Today’s commercial passive RFIDs report ranges of 5-10 meters at best. This reveals blind zones for RFIDs to be detected in warehouses, stores and factories today. We present PushID which achieves an 8x improvement in range over commercial RFID systems.

  • WiSh: Towards a Wireless Shape-aware World using Passive RFIDs

    WiSh gives ordinary objects shape-awareness, relaying their geometry by combining wireless sensing with graphics. It opens up novel applications: clothing that can detect a user’s posture, or even bridges that report their structural health.

  • Monitoring a Person’s Heart Rate and Respiratory Rate on a Shared Bed Using Geophones

    Heartbeat and respiration signals from multiple people received by geophones merge together. We build 3D characteristic model for each person relying on their spatical signatures.

  • RetroShape: Leveraging Rear-Surface Shape Displays for 2.5D Interaction on Smartwatches

    A tactile feedback system to enhance the user experience with a method unique to the smartwatch form factor, allowing the visual scene on screen to extend into 2.5D physical space.
