One of the best uses for wearable technology is to help you get around without being hunched over your smartphone. Google Glass and smartwatches do this, but you're still staring at a screen instead of enjoying the scenery. That's all set to change thanks to an Indian company that wants to put navigation equipment in your shoes. The Lechal interactive haptic footwear hooks up to your smartphone and when you reach a junction, vibrates the left (or right) foot depending on which turn you need to make. The gear is expected to launch in September, and you'll be able to choose between full shoes or just insoles that'll fit inside your regular pair of kicks. You can register your interest on Ducere's website right now, and can expect to pay $150 for a pair -- hopefully a portion of which will go to the creators of Red Dwarf, who came up with a similar idea 26 years ago.
