What do you do to get the directions of any place? Pull out your phone, and then go to the map, type the name of the place. That sounds pretty easy but not that easy if your hands are blocked. That’s why, students of Cornell University have developed a wearable-a GPS enabled top hat that only relies on directional sound for navigation.
The top hat works using the sound navigation system, which is a GPS navigation system to utilize the ear’s inherent ability of sound localization that guides the users to their destination. Audio tones are complied to ear buds with amplitude and phase shift to make it seem like the sound is coming from the direction you are supposed to go. The navigation is solely based on pre-programmed routes which you select using a small LCD screen and buttons. It’s both hands-free and language free, and there’s no need for instruction while turning down a side street.
It may look pretty ridiculous to you, but it’s still a prototype. Developers can use some variants of this to develop any navigation app. Maybe in the future, you will find an app that will help you to get directions without looking at your phone. That can save both you and your time. It could be especially vital for people with poor sight to provide them non-visual cues for GPS to work.
