Braille technology refers to tools and devices that help individuals who are blind or visually impaired read and write using the Braille system. This system uses raised dots arranged in specific patterns to represent letters and numbers, allowing users to feel the text with their fingers. Modern Braille technology includes electronic devices like Braille displays and notetakers, which convert digital text into Braille. These devices often connect to computers and smartphones, enabling users to access a wide range of information and communicate effectively in today's digital world.
