tactile-vision substitution

Tactile-vision substitution is a technology that allows visually impaired individuals to "see" using touch. It converts visual information, like images or text, into tactile feedback—such as raised patterns or vibrations—delivered through devices like gloves or specialized screens. This way, users can interpret visual details through their sense of touch, enabling them to perceive aspects of their surroundings, read text, or recognize objects without relying on sight. Essentially, it substitutes the sense of vision with a carefully designed tactile experience to improve independence and awareness.
