On the BBC R4 Today programme there is an item about a new AI based app to help blind people by describing their surroundings in some detail. The app is interactive in that you can ask it where the rest rooms are in a cafe, or to read a menu, or ask it how long to cook a cottage pie, or what the street scene is.
It will be on iPlayer for today, at six forty two, and is three and a half minutes long.
Unfortunately it fades into political correctness towards the end of the item.
