Apple's patent for a smart ring has been publicly disclosed, showing the accessory works with XR headsets or smart glasses to control connected devices through gestures. The headset identifies which device the user is looking at, then the ring's motion sensors interpret finger or wrist movements to execute commands, such as switching songs on a HomePod or launching apps on an iPad. The sensor technology aligns with motion sensors used in Apple Watch, iPhone, and Vision Pro. Apple has not announced release timing.
