Blind Requests Assistance
 A blind person requests assistance in the Be My Eyes app. The challenge that he/she needs help with can be anything from knowing the expiry date on the milk to navigating new surroundings.
 
 Volunteer Receives Video And Describes
 The volunteer helper receives a notification for help and a live video connection is established. From the live video the volunteer can help the blind person by answering the question they need answered.

An intriguing idea. It’s among many that are pushing the boundaries of what we can do as a group of millions of people now that we are constantly connected to one another.
