MIT helps to guide visually impaired people




The Massachusetts Institute of Technology ( MIT) is helping to guide visually impaired people by a team of researchers at the Institute of Computer Science and Artificial Intelligence at the Institute to develop a new wearable model designed to help people with impaired vision and mobility one day instead of the metal-tip wand for the disabled Visually.

The new model comes after the emergence of many innovations that can be worn, which does not provide any solutions suitable for disabled, The new system consists of a 3D camera that works on the depth sensor, and is equipped with a computer hanging on the neck around the chest level, Which displays symbols such as C for the chair and T for the table.

The camera senses the position of the objects and converts the signals into pulsating vibrations that alert the wearer to the body position. The motors on the model vibrate across a variety of patterns and frequencies to indicate things such as the distance between the person and the body in front of it, When the wearable device approaches the obstacle or body in front of it.

The MIT team has previously posted a video to test the model through a person wearing the model and trying to locate the chair and chair and avoid barriers and flawless walking through a labyrinth with and without the use of the visually impaired stick that allows the visually impaired person to quickly identify the surrounding environment.

“Having something that does not affect their other senses was important, we did not want to be dependent on the sound, and we do not want to have anything about the head, or vibrations on the neck,” Robert Katschman, one of the researchers, said in a statement on the Massachusetts Institute of Technology website. These things, however, will be none of them acceptable, and we found one area of ​​the body around the abdomen is the least used for other senses. ”

The model is a prototype that is not available for commercial use. The team used the system with only about 10 volunteers at the moment and the team is working on an environmentally friendly version of the outdoors. The camera uses a stereo camera and a larger library to recognize things beyond the chair and table knowledge. It can make walking in the busy city streets much easier for the visually impaired.
