Zoom on an evolutionary descriptive support of interior adapted to the setting of generalized accessibility of the buildings: the chain of displacement must be continuous and the identical access terms for all. To reach, circulate, receive information whatever its handicap: engine, auditive, visual or mental. The descriptive systems "full access" respect the constraints of comprehension, visibility (contrast environment, height of posting and materials anti-reflecting) and of legibility (contrast support, height of the characters) in position upright as in sitting position. The haptic universe makes it possible to explore information thanks to tactilo-kinesthetic perception for the public partially-sighted person and blind man: Braille, highlighted of writing and pictograms.
The option "full access" is the answer marcal to the problems as regards accessibility (ERP...) following the law of February 11th, 2005 for the chance and equal rights, the participation and citizenship of the handicapped people. It is the guarantee of a descriptive system in conformity with the law "handicap": rules of accessibility, information and indication. A study of establishment according to two axes of major reflection is necessary: the continuous chain of displacement and the logic of addressing of spaces of destination. The principal techniques implemented are the transcription in Braille, the writing in relief and wholesale characters, the recourse to the standardized pictograms and the marked out podo-tactile advance of totem. The full access makes it possible to integrate the handicapped people and to improve quality of life on the long run thanks to an environment accessible to all.
