Peripheral
Vision demonstrates the range of individual fields of vision.
Visitors place their nose in the center of a half-moon shaped
table and look at a point (indicated by a spring) across the
surface of the table. A friend positions a wooden block off
to the side of the table, far enough to the side so that it
can't be detected. Either a word or a symbol is painted in
color on the block. As the friend slides the block slowly
around the edge of the table towards the center, visitors
can first perceive motion, then color, then shape. The visitor
will find that reading is possible only in the very center
of the vision field.
