"We expect fewer injuries of blind and visually impaired swimmers from our pool wall warning system"

When a blind swimmer is touched on the head or back by a tennis ball attached to a long pole by the so-called "tapper", then he or she knows that the pool wall is coming up. If this signal is given too early or too late, it can result in disqualification or injuries. Researchers in Leipzig, Germany, are currently working on an alternative.
