Imagine controlling your music apps and effects by waving your arms in front of your iPad. You can do just that with iRings. They are detected by the front-facing camera, and using advanced image-recognition and geometric positioning technology, you can have control of assignable parameters within your apps. There’s plenty of room for experimentation, fun and performance. The ring itself is a simple double sided ring that fits between your fingers. Because the included app does the heavy lifting, this is a very inexpensive way of experimenting with your music. It can even be assigned to MIDI signals which can control hardware instruments.
