A videolink app is asking sighted volunteers to give descriptive help to blind people over the internet. But is it a good idea?
A can of soup feels very much like a can of beans. And if you shake them... they sound similar too. So if you're blind and don't fancy soup on toast tonight, you might want to think about downloading a new smartphone app which connects you via live video to a sighted volunteer who can tell you which can is which.
