Therefore, clear contrasts in the near environment are always helpful.
White surfaces on a black background are perceived signifficantly more clearly
than blue with a green background. This is exactly the principle of the
Blackbox with its loud neon-colours and the glistening white in the
darkness.
MORE THAN A PLEASURE …
The SWW-Blackbox is much more than a special attrraction on a funfair. It invites sighted and visually impaired people to become active and to simply experiment. For some physically and mentally disabled visually impaired people, a neon tennis-ball has the irresistable appeal toseize it. Even legally blind persons move this little, now brightly shining ball devotedly in front of their eyes again and again.
It's amazing also for the sighted. Just try it!
