Are you both bald and lost? Then the "SmartWig" might be just what you need.
The techno-toupe, which can read the wearer's brainwaves and direct them to their destination with onboard GPS, is the latest - and possibly wackiest - addition to the world of wearable computing from Japan.
The country that brought world-changing hits such as the Walkman and the pocket calculator, as well as instantly forgettable misses including the walking toaster, now offers a hi-tech hairpiece.
The proof-of-concept invention comes in three varieties.
Wearers of the Presentation Wig will be able to remotely control a laser pointer from their mop-top. They can move forward through a PowerPoint slide show by tugging the right sideburn and go back a page by pulling on the left.
The Navigation Wig uses GPS to speak to satellites and guide users to their destination with tiny vibrations on different parts of the head.
The Sensing Wig monitors body temperature, blood pressure and brainwaves and can record sounds and images to allow wearers to play back their day and see what set their systems aflutter.
"Most wearable devices have become neither common nor popular," developers Hiroaki Tobita and Takuya Kuzi said in an essay issued last year.
"We think one of the biggest reasons is the style ... the focus has been function, not style."
They said the "natural appearance" of their invention - which can be made from human hair - could prove a selling point.
A spokeswoman for Sony said on Thursday that patents for the SmartWig had been filed in the European Union and the US, although there were no plans to commercialise the product.
Despite its success with the Walkman, Sony has struggled in recent years in its mainstay electronics business.
Sony's chief executive officer Kazuo Hirai told media last month he was pouring business resources into the development of wearable devices, which also includes the company's second-generation smartwatch.
