Here is a smart wearable device that helps visually impaired people find their way around their city. The FeelSpace Navigation Belt uses vibrations to guide the wearer in the right direction. For instance, the right side of the belt vibrates when the wearer needs to go right.
To get started, simply put the belt on, use the feelSpace app to choose where you want to go, and follow the signals. The belt offers 360-degree coverage. More information is available here.
