It is the evolution of LOGES, this path, with its codes, while maintaining the fundamental characteristics of the previous tactile system, widespread in infrastructures and public offices, has been adapted, in the straight code, to European Regulations. All codes are equipped with a RFG Transponder having a round detector on its back. This system provides further information on the entire path. Using special devices users will receive further information.
The system has different reliefs and grooves for the different codes. Their sizes can to be easily perceived by the plantar tactile sense. The surface is rough and non-slip while the bottom of the plate is smooth, to let the White stick slide. Codes are tapered in order not to hinder or discomfort the walking of persons with reduced mobility.
The system is based on two base codes and four second level codes.
Base codes: they are 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
It 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.
