Abstract
A mobility tool for the blind and visually impaired includes a rod and an earpiece. The earpiece is configured to position on an ear of a user so that a first speaker is positioned proximate to an ear canal of the ear. A sensing module is coupled to a lower end of the rod and is configured to detect a temperature hazard, a water hazard, and a traffic hazard. A navigation and communications module is coupled to an upper end of the rod and is operationally coupled to the sensing module and the earpiece. The navigation and communications module comprises a GPS transceiver that is configured to send and receive location coordinates. The sensing module is configured to detect a respective hazard along a route, positioning the first speaker to selectively broadcasting directions for the route and a warning of the respective hazard to the user.
