I feel my way into the park, clocking with my hands a fence, a bench, a railing, bushes and trees (which are big and rough).
The process is slow, halting, and daunting, for this is the first time I have been blind to open space around me.
At first I am definitely out of my comfort zone, but by the end of an hour in total darkness, I am beginning to appreciate the many different forms of awareness. The cane helps, sounds orient me, but most important is the voice of my guide Mary, as she patiently leads me through what would otherwise be an obstacle course.
I am at Dialogue in the Dark, an immersive exhibition that enables sighted people to experience what it is to live with a visual impairment.
The project, which was developed in Germany in 1988, has been mounted in 45 countries across the world.
