Short range wireless powered ring for user interaction and sensing

摘要: In general, the short range wireless powered ring described herein pertains to a finger-worn ring. one embodiment has small interaction area towards palm of hand that employs sensors sense user input and can interpret this other data. For example, as scroll select actions. The communicates interactions data wirelessly using low-power solution. contains coil circuitry for energy harvesting from enabled devices such as, NFC phones, while users interact with their devices. A built in rechargeable battery is used store scavenged energy. may also contain physiological inertial sensors. provide readily available device form factor an easily accessible source ease use.
