People, who are disabled from vision, need an aid to foresee the roads and anything else that is lying in front. The AngelWing is one system that is designed specially for the blinds so that they can sense whatever is occurring within a particular range. The system consists of a set of Bluetooth device which includes a transmitter, earphone and sensor. The entire system is compact and hence extremely useful. The sensor looks like a white and red regular stick but it is much more efficient than the regular ones. The Bluetooth device is a tiny tool to be attached to the ears.
