avrings

Av rings, or avrings, are wearable devices designed in a ring form to provide integrated audio-visual feedback for augmented and mixed reality experiences. A typical av ring embeds small speakers, an LED ring, a touch or gesture sensor, and a compact vibration motor within a finger-sized enclosure. The design emphasizes discreet, hands-free interaction and contextual cues rather than standalone functionality.

Hardware and interface: Av rings use a low-power microcontroller, a wireless module (usually Bluetooth), a small battery, and an audio driver. Optional components include capacitive touch sensors, pressure sensors, and micro LEDs for status indications. The form factor prioritizes comfort, heat management, and battery life sufficient for several hours of moderate use.

Functions and applications: They can deliver spatial audio to accompany AR content and illuminate the environment with ambient lighting cues. Haptic feedback is used for tactile interaction, while touch or gesture inputs enable basic control without removing the ring. Common use cases include gaming, live performances, accessibility aids for notifications, and collaboration in VR/AR workflows.

Development and status: Av rings constitute a niche segment within wearable technology. There is no universal standard, resulting in a variety of designs and software ecosystems. Privacy and safety concerns center on sensor data, visual distraction in public spaces, and the potential for unintended interactions in social settings.

Name and scope: The term av ring derives from "audio-visual ring." In some contexts avrings describe broader ring-shaped devices that deliver sensory feedback, whereas others refer to specific product lines from different manufacturers.
