Here is a smart navigation belt that uses vibrations to guide you to your destination without any distracting audio or visual cues. Just choose where you want to go on your smartphone, and the Ubivade belt does the rest. It has 16 vibrating motors and can be used whether you are traveling on foot, by bus, or using other means.
The belt is compatible with iOS and Android devices. The battery life lasts a week. You can find out more about it on Kickstarter.
