Sorry if this post makes me sound ignorant, but I just don't understand what this is, and I am curious.
Sometimes I will see someone holding what looks like one of those canes that blind people use to help themselves get around.
However, instead of passing it back and forth along the pavement, like I am used to seeing blind people do, they hold it up in the air in front of them like they are about to jab someone with it.
I've seen people hold it straight ahead of them as they are walking, and I've seen people wave it back and forth in the air in front of them.
A man was waving a cane like this in the air the other day and he came up to me and asked me for directions. He was wearing glasses (normal glasses, not super thick glasses) and was not blind.
I never saw anything like this in the US. I have seen blind people using canes the normal way, sweeping them back and forth along the pavement, in both countries.
Can someone explain to me what these canes are for? It seems dangerous to be walking along a city pavement pointing a cane in front of you like a weapon.
