In a world where technology is transforming lives everyday, there is another good news for the blind. A young engineering student from Arunachal Pradesh in India has invented goggles that can protect visually impaired people from bumping into taller obstacles on the way. Fitted with sensors, the G4B or Goggles for the Blind is designed to detect obstacles that are higher from the ground within the distance of 2 meters and alert the user through vibrations if he or she gets closer. It is said that the G4B has three sensors: one each on the left, right and at the Center, designed to vibrate as per the position and direction of the obstacle. More interestingly, it is said that the intensity of vibration is determined by the distance between the person and the obstacles ahead of him or her. The closer one gets to the obstacles, the stronger the vibration becomes. It uses echo-location, similar to the navigation mechanism used by bats. If this technology comes to the market, I think it can make life much easier for the visually impaired population as a whole.
