Blind Swimmers (and/or Engineers)
I started thinking of mad ideas for helping people to swim without sight. Does anyone have experience with anything that falls into the area of obstacle detection (wall) and guidance (staying in the lane)? I don't mean being hit on the head by a pole with a tennis ball on the end or just stroke counting. More like electronics.
Well, any experience anyone has of being a blind swimmer and/or working with a blind swimmer would be interesting hear from.
