Although there are many new technologies that can assist the disabled people, 3-D technology has always been a big success. The Massachusetts Institute of Technology (MIT) is working on a technology that can help the visually impaired. They have come up with a new wearable technology that helps the visually impaired to navigate easily through the surroundings. The device can find out if there is any kind of obstacle in front of the user and can help them identify it. This eliminates the need of a partner or a walking stick. Using technology similar to that employed to (literally and figuratively) drives 3D cars, the device relies on a system able to interpret 3D camera data. The technology is quite simple and easy. With the wearable technology one can identify the obstacles when there is a vibration detected in the motor. “Primarily, the real-world applications are day-to-day scenarios [in which a] user with visual impairment is confronted with navigating a cafeteria, finding his or her way around in a hotel lobby, or finding an empty chair in the bus or train,” Dr. Hsueh-Cheng Wang, a former postdoctoral researcher at MIT and now an assistant professor of electrical and computer engineering at National Chiao Tung University in Taiwan, told. As a whole it focuses its attention on the day to day things which the blind people come across and finds a better way to cope up with all the difficulties.
