MIT researchers have developed a prototype for a wearable navigation system that can guide people with visual impairments. The device is to be wrapped around the users chest and uses a 3D depth-sensing camera to alert wearers of obstructions in their path through an electronic braille pad. The braille pad helps provide context for the users, informing them of the specifics of the object through a simple labeling system that recognizes tables as 't' or chairs as 'c.'
The device, which frees users from having to use a cane, offers an added dimension of protection and independence among the visually impaired community. The technology uses haptic sensors to help the wearer observe their surroundings, enhancing mobility and autonomy.
