Researchers from the American Scientific Academy Mass General Brigham have developed a technical system that helps the visually impaired avoid traffic collisions by 37 percent.
According to the British Daily Mail, the new technology consists of a video camera attached to a person's chest and a "vibrating wristband" system and is directed to assist the visually impaired, blind and those who use a long stick or a guide dog.
The researchers explained that the experimental device and data recording unit are placed in a backpack with a belt with a wide-angle camera attached to the chest on the belt, in addition to two Bluetooth-connected bracelets worn by the user. .
They added that if an imminent collision is detected on the left or right side, the corresponding wristband will vibrate, and a head-on collision will cause both bracelets to vibrate, alerting the user and specifying his steps.
"Separate walking is an essential part of daily life for many visually impaired people, but they are at greater risk of bumping into objects when they walk alone," said study researcher Gang Lu and associate professor of ophthalmology at Harvard Medical School.
