Other ways to navigate without sight...

• Human echolocation is an ability of humans to detect objects in their environment by sensing echoes from those objects. By actively creating sounds – for example, by tapping their canes, lightly stomping their foot or making clicking noises with their mouths – people trained to orientate with echolocation can interpret the sound waves reflected by nearby objects, accurately identifying their location and size. This ability is used by some blind people for acoustic wayfinding, or navigating within their environment using auditory rather than visual cues.

• Canes, Users swing the cane as they walk. This helps them find objects and swerve around them.
• Trained guide dogs
• Braille
• Sound,
• Not all pedestrian crossings make sound. there are often crossings close to each other, or busy crossings where sound is not always the best means of navigation
• At most crossings now there is a small cone on the underneath of the boxes, this cone spins when the green light comes on using a different sense to help people to navigate individually
• difference in the texture of pavements, this is something I had not paid much attention to before, using the sense of touch of the feel to navigate an area.
