Universal design requirement in public accessible buildings.

Tactile signs and Braille are used to help blind and visually impaired people navigate more easily.

On tactile signs, the letters and symbols are raised, so visually impaired people can understand the information on the sign by touching it.

The signs can be supplied in high quality constrasting plastics and metals.

Norwegian Braille association's requirements for signs

  • Signs should be placed at eye level, which is a center height of 150cm

  • No obstruction of the sign. Therefore, no objects should be placed in front of the sign.

  • For signs that can be approached closely, smaller amounts of text should be designed with raised tactile letters and Braille.

  • The raised tactile lettering should have a tactility of at least 1 millimeter.

  • The Braille should be placed so that it starts directly below where the tactile lettering.

  • The Braille on signs should have a tactility of at least 0.6 millimeters.

  • Signs placed against a light background should have a dark background with white or slightly subdued text color.

  • The luminance contrast between text and background on the sign, and between the sign and the wall, should be at least 0.8.

  • The font should be clean without serifs, not italicized and with raised tactile letters.

  • Indoor signs should be illuminated with at least 300 lux.

  • Signs should have a matt surface, as glossy surfaces give annoying reflections and glare.
