This year's CES has introduced us to a number of devices that cater to specific people. That includes IK Multimedia's iRing accessory, designed for aspiring DJs who'd like to control their iOS music apps with gestures... and a dash of showmanship. So long as a user's wearing the iRing, the iDevice's front camera picks the gesture controls up, and the peripheral's accompanying app translates them to commands music software can understand. According to the company (the same one responsible for a few other music accessories for iOS), the iRing's capable of controlling not only basic music apps, but also advanced ones designed for those who mix their own tunes. It also comes with a couple of its own music-editing apps that one can use to add effects and create non-stop loops. Those who prefer waving their hands in the air over poking at on-screen controls can get the iRing in various music and electronic retailers worldwide for $25.
