Descrição
Guides consist of a path of narrow ridges adjacent the longitudinal direction of approximately 5 cm are interrupted at regular intervals.
This latest outage of (rain) water and dirt as possible. Pollution can visually guide the otherwise not perceive.
Many visually impaired, the vast majority of the visually impaired, have a limited field of view. An immediately apparent ripples in contrast against the background colors is necessary because a small part of the facial field guide-line/rectangle already be recognizable.
Ripples should be narrow (approx. 10 mm) and a diameter to have adapted to the local surface roughness.
On a flat surface (linoleum, etc.) has a diameter of 10 mm base and 1.5 mm high to 2 mm is sufficient. A rough surface requires a triangular cross section about pole use and to prevent enkelverzwikking, base 10 mm, high up to 4.5 mm.
Ripples have a heart-to-center distance of about 60 to 70 mm. It has only one or two ridges in the sole.
We take tactile ripples in the foot because of the sole between the ripples verbuigt and fell. The bending angle is the third and sag to the fourth power depending on the distance between the ripples. Broad ridges and ripples slightly closer to each other therefore feel little or no through the sole. If they still perceive is based on (re) sprain in the ankle joint. This happens when the ripples wide, rounded or sinusoidal-shaped and higher than 5 mm.
As we approached transverse guides also should be observed, the guide-line/rectangle at least one step (60 cm) wide, so about 10 ribs side. Because we expected from the different ways in which the visually impaired the (other) senses efforts to orient, we have a pattern, design and applications developed which are used to connect them to all visually impaired. Variables characteristics ripples have about the area or roughness of the surface with our application method easy to implement.
Guides to bring us to places we provide any type of tile or clinker which the ripples are already fitted with the correct dimensions and (contrast) color.
