Motion controller for iPhone and iPad that uses hand gestures to control parameters of effects and other items in the music performances by simply moving your hands in front of the device. It uses patented advanced image-recognition, motion control and precise geometric positioning technology to determine the exact position of the wearable rings, recognizing and tracking the printed dot patterns allowing for controlling various app parameters, without touching the device. For DJs or music lovers, it can be used to create real-time, non-stop dance grooves and scores with the included iRing Music Maker app. The motion controller is a simple double sided ring that fits comfortably between the fingers – on one side there is a linear pattern of three dots, on the other a triangular pattern. The iRing app uses the front-facing camera on the device and advanced volumetric positioning algorithms to recognize and determine the exact position of the ring in relation to the selected device camera. This precise reading of the position of the ring is converted by the app into music or MIDI control messages. Because movements can be recognized along the three axis, with two rings you can control up to six parameters simultaneously. On top of movements also certain gestures are recognized (like the rotation of the ring) greatly enlarging the music expression possibilities. The package includes two thermoplastic rings in the same colour. Dimensions: 42 x 30 x 27 mm. Weight: 10 g. Green colour.
