If you're already over the smartwatch craze, why not try a 'smartwig'? Sony filed for a patent for a hairpiece with vibrating sideburns.

The SmartWig is jammed packed with sensors that vibrate on the user's head to send them messages. The patent also says the wig may include special fibers that look natural and can change shape.

The hair-raising idea will monitor your health, give directions and could "be made from horse hair, human hair, wool, feathers, yak hair or any kind of synthetic material."

The wig has already been tested on Sony employees who switched slides during a presentation by tapping their sideburns.

"'One or two switch buttons may be provided under the sideburns of the wig, and the one or more buttons are connected to the external computer via a wireless connection," the patent reads.

The SmartWig also has a built-in GPS chip and laser pointer.

"The laser pointer may, for example, be arranged on a forehead part of the wig, so that the user may point out relevant information on the projected slide in the above-explained presentation mode."
