Google's smart headphone wire has touch sensing for controls
CNET --------- Google is working on a prototype headphone cord with touch sensing for controls. Twisting, flicking, pinching, grabbing and patting the wire, or sliding your fingers along it, triggers different functions -- tapping for play and pause, for example, double tapping to move to the next track, rolling between the fingers for volume. The braided wire also has fiber optic strands that light up in different colors to let you know what control you've activated. To learn more click on the picture below to read the article.
