Touch-based interfaces are still a little thin on the ground, but that doesn’t mean people aren’t working on new ways to engage the sense that gets little attention from technology. Take, for example, this ‘augmented spatial awareness’ system being developed in Japan that acts as a set of electronic whiskers to detect motion in the vicinity of your head. The designers cite uses such as helping the blind and making driving safer, and more power to them for that, but I’m thinking that the first commercial use will be in the gaming or entertainment industries.
