Braille signs are signage that is designed for visually impaired people and includes both raised text and tactile images. The Braille dots are arranged in a way that corresponds to the letters of the alphabet, as well as numbers and other symbols. These signs are used in public spaces to provide information about things such as room numbers, restroom locations, and emergency exits. Braille signs are required in many countries by law to ensure that buildings are accessible to everyone, including those with disabilities. They are typically made from durable materials such as plastic or metal and may include additional information such as raised pictograms or lettering to make them more visible to people with low vision.
