In the first GE lesson, our group raised a problem which a blind gym coach may encounter. The coach may touch certain part of the client's body and this may cause sexual harassment!
I think that the gym suit with magnetic property can help to solve this problem. With the client wearing magnetic gym suit and the coach wearing magnetic gloves, part of the suit and the gloves would slightly repel each other when the coach touches certain part of the client's body.
Of course, both the suit and the gloves have to be of the same pole!
