Braille and tactile signs are designed to assist individuals who are visually impaired or blind.Braille is a system of raised dots that can be felt with the fingertips and used to read with touch. It was invented by Louis Braille, a Frenchman who lost his sight as a result of a childhood accident. Braille characters are small rectangular blocks, or cells, that contain tiny palpable bumps called raised dots. The number and arrangement of these dots distinguish one character from another.On the other hand, tactile signs use raised letters, numbers, pictograms, and sometimes braille to communicate information through touch. They are often used in public places such as schools, hospitals, and office buildings to provide directions, room numbers, and other important information. These signs can be made from a variety of materials, including metal, plastic, and wood, and are usually designed to contrast visually with their surroundings for those who have low vision.

Both Braille and tactile signs play a crucial role in providing accessibility and promoting independence for people with visual impairments.
