Robot like navigation systems and 3D Braille map to guide way for the blind

Advanced location and navigation systems help robots locate their positions. Indeed, cameras, sensors, accelerometers and gyroscopes are the key location and navigation technologies robots often come with. A team of researchers at the Pierre and Marie Curie University in Paris, France is now working to utilize these sophisticated location and navigation systems with a pair of glasses and 3D Braille map to help blind people find their way indoor and outdoor spaces easily.

The robotic system, which is under development by Edwige Pissaloux and peers of the university’s Institute of Intelligent Systems and Robotics, is simply an effort to create a Braille 3D map based on the user’s position and environment. It is made possible through the use of advanced technologies like sensors, cameras and a pair of glasses that we see in robots. The wearers of the device will be updated with the 3D map on a portable Braille device, which they can carry around while going out for a walk on street.

The technology will eventually help blind people easily make their way, Pissaloux says. However, it is not a device just to show way for its users. Apart from just warning users of the obstacles on the way ahead, the system can recognize various social spaces like a bus station, library and pharmacy and update the users with the details, she adds.

The system works with a pair of cameras on each side of the glasses producing 3D images of particular location. Later, a processor assesses the snaps and produces a 3D map out of them. It will be combined with the information from the system’s gyroscopes and accelerometers. The outcome will be the exact information that will show the way for the blind person on street.
