Sony has officially introduced its wearable Motion Sonic device on Indiegogo. The new tech is described as an effects gear that syncs with your body's motion to control sound as you play music. It fits around your wrist or hand to not interfere with your movement while strumming a guitar or tapping piano keys. While performing, users can alter the pitch or add effects with the wave of their hand or delay the music by moving up and down. Both the controller and the instrument link up to your iPhone via the accompanying iOS app, where music can be recorded and all the effects are saved. Backers in the US and Japan can get a first look at the new gadget and have input on the final design.
