A smart ring with a tiny camera lets users point and click to control home devices

Jan 09, 2025

Researchers have developed IRIS, a smart ring that allows users to point and click to control smart devices. The prototype Bluetooth ring contains a small camera which sends an image of the selected device to the user's phone. The user can control the device clicking a small button or -- for devices with gradient controls, such as a speaker's volume -- rotating the ring.
