Mites: A Ubiquitous Sensing System and Stack
2018-018 Mites: A Ubiquitous Sensing System and Stack
Abstract
https://mites.io/
Smart spaces and the internet of things rely on robust sensing of the environment, achieved by upgrading a space with expensive smart devices that do not talk to one another or tagging devices/rooms with after-market sensors. The latter is more flexible and intelligent...

RFTouch: Robust Touch Segmentation for On-Skin AR/VR Interfaces
2018-258 Actitouch: Robust Touch Detection for On-Skin AR/VR Interfaces
Abstract
ActiTouch enables precise, low-latency touch segmentation by using the body as an RF waveguide. Users need only wear one wristband emitter (e.g., smartwatchs) and a head-worn receiver (e.g., AR/VR headsets). When a user touches the other arm, a circuit path is formed,...
