A couple of years ago we saw a pair of shoes with built-in navigation capabilities. That was a one-off, but it looks like you’ll be able to buy something similar to that in the near future. A company called Ducere Technologies claims that it’s working on Lechal, a pair of shoes as well as insoles that can guide its wearer through haptic feedback.
Both the shoes and the insoles have a removable Bluetooth module that works with a mobile device and a complementary app. You’ll set your destination on the app, and the corresponding shoe will vibrate to indicate which direction you should take.
I expect the final product will have a click-the-heels gesture to point you home. You can sign up on the Lechal website to be notified when pre-orders begin.
