VisRing: A Display-Extended Smartring for Nano Visualizations
summary
A wearable ring integrates a 160×32 bendable OLED into a multilayer PCB and 3D-printed housing, packing IMU, PPG, temperature sensor, Bluetooth, and MCU into a SoC-like design that wraps 270–360° around the finger. The prototype weighs 6.6 g and costs ~$35 to build, uses a 60 mAh battery that gives roughly 2 hours of continuous display, ships with a nano-visualization library (bars, lines, radial progress, heart rate) and a 12-participant qualitative study showing comfort and fit issues.
