Be My AI is an artificial intelligence engine that is being tested by Be My Eyes - an app that connects visually impaired smartphone users to sighted assistance. There are thousands of people currently testing the AI offering and it allows them to take pictures of their surroundings and the AI will describe, with great detail, what is in that image. For example, it can be helpful for things like navigation, describing clothing items or reading menus. However, a lot of its testers are greatly concerned over a recent change where the AI will no longer describe what is in an image, if there is a human present. Sean Dilley is a BBC journalist and user of Be My AI, and he describes the issues that could be behind these changes.

*After the time of recording this programme, it appears that the feature has been restored for some users.

Orla Guerin is the BBC's Senior International Correspondent and she has recently been back to war-torn Yemen, to catch up with a blind boy she met there two years ago. Ahmed made a particular impression because he was teaching his peers in his bombed-out school. Orla talks with Peter about what Ahmed is like and about his future ambitions.
