Braille signage typically consists of raised characters that can be felt with the fingertips. These characters are embossed onto the sign surface, allowing individuals to read the information using their sense of touch. Braille signage is usually accompanied by visual text and graphics to accommodate individuals with varying degrees of visual impairment.
Braille signage is essential for promoting accessibility and inclusivity. It allows individuals with visual impairments to navigate public spaces safely and independently by providing information about room numbers, restroom locations, elevator access, emergency exits, and other important details. Additionally, Braille signage can also include tactile symbols to convey information about specific amenities, such as elevators, staircases, restrooms, or parking spaces.
