[This is from the Blink Talk Conference]

A pilot study proposal has been submitted to the University of
Pittsburgh to test Pathfinder tactile tiles.  The purpose is to see
if the tiles (designed to aid and alert blind pedestrians) are
durable in cold and snowy conditions and appropriate for
installation at intersections, curb cuts, bus stops, steps and so
on.  The tiles have raised "polka dots" about one fourth inch high
and one inch round or raised bars which are oriented in the
direction of travel.  The bumps can be felt through one's shoes.
The tiles are bright yellow to provide contrast with the pavement.
Pathfinder Tiles are currently in use in the San Francisco Bay Area
(BART) subway platforms, in Sacramento, and in Toronto.

Before a decision is made to participate in this study, I'm
interested in hearing from people who are blind or have low vision
in regard to the helpfulness and/or necessity of these tiles (based
on actual experience with the tiles or on theoretical viewpoints).
I am also interested in hearing from persons with mobility
impairments and balance problems as to whether or not these tiles
would pose any threats to their safety or ease in traveling (via
wheelchair or on foot).  Again, this can be based on experience or
conjecture.

 What do you like about the tiles?  What don't you like about the
tiles?
