While is beginning to become a viable input solution for and , optical tracking precision remains a challenge that might not fully be resolved without assistance. That’s where comes in. Developed by researchers at the University of Washington, the new electromagnetic tracking system promises a combination of high-resolution tracking and low power consumption that could benefit AR, VR, and broader wearable device applications.
AuraRing consists of two pieces. The first is an index finger-sized ring containing a coil of wire wrapped 800 times around a 3D printed loop, using a tiny battery to generate an oscillating magnetic field with only 2.3 milliwatts of power. A wristband then uses three sensor coils to determine the ring’s five degree of freedom (DoF) orientation at any point in time. The
