Sony has filed a patent for a “wearable computing device, comprising a wig that is adapted to cover at least a part of a head of a user, at least one sensor for providing input data, a processing unit that is coupled to the at least one sensor for processing said input data, and a communication interface that is coupled to the processing unit for communicating with a second computing device.”

Thats right. Weve had smart watches and smart glasses – now its time for the smart wig.

It might sound ridiculous, but Sony believes there are several applications for the technology. The sensors could detect a variety of environmental data including sound, humidity and density of CO2, as well as data from the human body, including temperature, pulse, blood pressure and brain wave activity, meaning the devices could have potential applications in the mHealth space.

Slightly harder to envisage is the navigation wig scenario, which Sony points out could be used to direct blind people using motors positioned on the back of the wig to give tactile feedback.
