Sony's engineers have filed a patent for a new form of wearable tech, only this one differs from the watches and glasses currently doing the rounds. Sony's come up with the idea of a smart wig, with embedded rumble tech to tap the wearer on the scalp when they get a message.
Sony's patent is absolutely baffling from the very first sentence, in which it tells us it can foresee a future for a "Wearable computing device, comprising a wig that is adapted to cover at least a part of a head of a user." The smartwig would be tethered to a partner device, which would then tell its head-based companion to vibrate whenever there's something actionable going on on the smartphone.
The patent lurches into even more peculiar territory the further you read, with Sony suggesting there could also be a camera, ultrasound-based proximity scanner and laser pointer incorporated into its smartwig.
