Daisy Duke hot pants that replace sat-nav by vibrating body when you need to turn

After cars that drive themselves, phones you can talk to and shopping delivered by drone, it's hard to guess where technology is headed next. Step forward these shorts, which reveal more than a pair of legs – they also tell the wearer where to go. The Daisy Duke-style shorts send a vibration to different sides of the body, indicating when and where to turn. Step in the right direction: The Spinali Design shorts, left, and jeans, right, send a vibration to different sides of the body, indicating when and where to turn. They are connected to a smartphone by Bluetooth, and so when a route is set on the phone it sends the directions through to the shorts. The shorts also buzz to let the wearer know if they have an incoming text or call, taking away the need to keep checking the phone.
