IK Multimedia has released the iRing hardware in conjunction with a couple apps for using the device. With compatible apps such as GrooveMaker 2, iRing FX/Controller, iRing Music Maker, and DJ Rig, you can calibrate your iRings, create some grooves, and control some cool effects by simply moving your hands around where your iDevice camera can see them. The rings have two sides: one with three dots in a straight line, the other with three dots in a triangle pattern. The iRing doesn’t fit on a finger like a traditional ring; it fits between two fingers so it’s easy to pick up and put down one handed. The rings make use of your iDevice front facing camera to locate the dots. By moving your hands in three dimensions you can control different parameters of the groove or of effects.
