Sony's 'Wearable Tech' Idea: a Wig

Watch out Google Glass, Sony is delving into wearable technology—and fashion, apparently—with a patent for a wig that can check your blood pressure, detect objects around you, and even help blind people navigate roads, the BBC reports. Sony thinks its SmartWig, worn "in addition to natural hair," could become "very popular" as a "technically intelligent item and fashion item at the same time" since it would be more comfortable than other wearable devices. And while it's obvious when a person is using Google Glass, at least parts of the SmartWig could be hidden from view.

Though there are no commercial plans yet, three prototypes have been made, including one that flips PowerPoint slides when pulled left or right. The patent notes the SmartWig could also use ultrasound waves and sensors to spot a person's surroundings and detect the wearer's pulse, temperature, and blood pressure. Another bonus: It can be made from horse, yak, buffalo, or human hair, as well as feathers, wool, or synthetic material. "It's an interesting idea but I think it would be very difficult for Sony to commercialize," a fund manager told Bloomberg. "Who will want to use this wig will become a problem."
