This is a helping tool for the blind. In this technology a blind person will wear the technology around his neck. This would basically be a combination of cameras and optical range finders to detect and map the surroundings of the person as he walks around a new location. As we have the map of a place ,we can use virtual markers to navigate the person to a location of his choice like the place where he keeps his medicines or other important items.
This would be great medical tool to help the blind navigate new places.
This can also be coupled with NFC technology. Here this device will download the map of a particular area (room)from an NFC transmitter located at the entrance of the area. This makes this technology more universal to adapt because more unexplored areas could be navigated without the pre-run (to map).
