Tech should make you think of projects like this – Be My Eyes. This is an incredible project that connects independently living blind people to a wide community of sited people through video calling. This means that if a blind person is in their home for example, they go to the fridge and take out a packet of food, but they can’t read the sell-by-date to read if it’s safe to eat. So they video call someone through the app – show them the packet through the video call, and the person on the other end can read the packet for them and tell them whether its safe to eat.
