Wristband that could help the blind to see
Technology that helps the blind move around usually focuses on replacing the loss of sight with audio cues.
However, for the visually impaired, the sense of touch is much stronger and it is this that a new wristband depends on.
Created by a company called WearWorks, the wristband uses vibrations to guide people around. It does this through the phones that users carry.
The wristband connects to a handset, and there's feedback to help use the app. It tells the user where to go and guides them there. It buzzes when the user faces the wrong way and stays silent when the person is on the right way.
