Researchers at the University of Washington have created a ring that can detect the location of someone’s index finger and hand movements. This wearable magnetic tracking system, named AuraRing, contains an embedded electromagnetic transmitter coil and a wristband with sensor coils. The ring sends signals that are picked up by the wristband to identify the exact finger position. The AuraRing consumes only 2.3 milliwatts of power using oscillating magnetic fields, compared to other smart rings that require data streaming using wireless communication.

The AuraRing can be used across multiple industries, and added to smartwatches and other wristband devices for additional benefits. It can also be used to pick up handwriting or provide a virtual reality avatar hand to mimic what someone’s hand is doing with their actual hand. The ring and wristband can be useful for more than just gaming and smartphone capabilities. “It’s all about super powers,” stated by Salemi Parizi, a doctoral student in electrical and computer engineering. This product is still undergoing research and testing before administering to the market.
