    Researchers developing smart ring for healthcare and extended reality
    The OmniRing doesn’t have a display and so can support a longer battery life. This makes it possible to wear the ring all the time, including while sleeping and swimming, enabling the ring to capture deeper and more intimate levels of sensing information.  Credit: Taiting Lu

    A team of researchers in the Penn State School of Electrical Engineering and Computer Science aims to enable health care and extended reality—which encompasses virtual, augmented and mixed reality—with their smart sensing ring, OmniRing.

    The ring uses both inertial measurement unit (IMU) sensors, which can capture location, speed and rotation of the fingers, and photoplethysmography (PPG) sensors, which utilize an infrared light to measure volumetric changes in blood circulation...
