Navigational technology has come quite far, but the 'Proximity Hat' looks to add an additional layer to the experience with pressure feedback for the visually impaired. Instead of using providing visual or auditory cues, the 'Proximity Hat' works by applying pressure to the wearers head the closer they get to a designated location.
Developed by Florian Braun at the Karlsruhe Institute of Technology in Germany, the 'Proximity Hat' is indeed ideal for guiding the visually impaired, but also shows promise with other markets as well. The 'Proximity Hat' could work wonders for firefighters to help make it through smoke-filled buildings or as a way to worn wearers of unseen dangers.
The 'Proximity Hat' features six ultrasonic sensors that each takes 50 measurements per second to help ensure accuracy.
