Wink-activated iPod Controller - Is this Necessary!?

This article is basically about a new product that allows you to wink to control your ipod. It uses sensors and microcomputers to tell the difference in your skin, so when you wink the Ipod will do different things. You can pause, start, stop, skip, and other functions just like if you were using your fingers.

This product seems pretty pointless to me, seeing as it is not that hard to just change a song with your fingers. It is interesting how it uses sensors and a microcomputer, but I don't feel like the price will be worth it. As an impact for society, I think the only way this will be useful to people is if their hands are full with something else, and they need to change their song on their ipod. We will have to wait and see if this product will be a big hit.
