Laugh it up

ARE you both bald and lost? Then the ‘‘SmartWig’’ might be just what you need. The wacky Japanese technotoupe can read the wearer’s brainwaves and direct them to their destination with onboard GPS. The proof-of-concept invention comes in three impressive 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 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 them aflutter.
