One Ring to Rule Them All
The remote, however, is of dubious value. Sure you can skip songs, etc. but it just doesn't have the same ease of use as the wheel. Other remotes, or for that matter interfaces, still use the same old push button rewind/play/fast forward buttons that we've come to love(?) for years.
Recently we were fumbling for the scroll wheel hidden away in a pocket and thought 'why isn't there a device that extends the scroll paradigm but isn't yetanotherdarnthing to carry around.' Why isn't there a bluetooth or infrared module that plugs into the remote port of your favorite player and can be controlled with a simple device?
Fab miniaturization has progressed to a point where it's technically feasible to make very small devices. So why aren't we seeing very small remotes? Yes there are issues with making a universal module that understands all devices. But with enough interest in a clever remote design we bet that a 'rosetta stone' controller would be a work in earnest.
How about a ring that functions as a remote control? A simple band could very easily duplicate all the functions now found on the iPod scroll wheel. Touch sensitive or a band within a band - one ring to control any device attached to the universal controller.
We're betting that clever designers will be able to hide or integrate such circuitry very soon. Let's hope that battery designers are equally clever.
