LOGES was born in 1995, it is a special embossed tactile paving allowing visually impaired persons to be completely independent when moving. The name is the Italian acronym for Linea di Orientamento Guida E Sicurezza; its surface is specially embossed in order to be perceived by feet. On these surfaces information codes are embossed, providing easy understandable guiding paths helping blind and visually impaired persons to orient and be independent
The system is based on two base codes and four second level codes.
Base codes: Straight Path and Stop Danger always detectable (also if the path is only assisted by natural guidance)
Second level codes: adding valuable information detectable because of their different structure. They are always included in paths or tactile signs
I t provides direction information and warnings through four different senses:
- the kinesthetic and the plantar tactile sense
- the hand tactile sense (through the white cane)
Provides acoustic information coming from the tip of the stick or from the sole of the shoe, given the difference in sounds produced by tactile and non tactile paving
- chromatic and luminance contrast
Provides visual information to visually impaired persons because of the difference in the chromatic and luminance contrast between the path and the surrounding paving.
