Inventables Pocket Pal MP3 Player

Inventables has just rolled out its Pocket Pal MP3 player concept which features an interface on the outside, controlling your tunes which are located within your pocket without having to reach inside of it.

This is a concept for a control interface using a magnetic knob on a MP3 player. The knob can be removed and placed outside your pocket to control the volume and skip to the next song. It can be implemented using hemispherical oriented magnets and existing magnetic field sensors.

And I thought that data and magnets don't really play nice with one another...
