Apple patents the Smartring

I think this form factor is pretty inevitable for mobile input devices.

As wearables and such continue to become more prolific, I'd venture we'll see a day where holding a mobile phone in front of your face will be extremely uncool compared to newer more subtle input devices.

Not quite the muscle movement based input of "Rainbow's End", but getting there.

maybe they'll acquire this company soon https://ringly.com/

Will it be called iRing?
