How 'super vision' will change the way we see the world

Computers are getting better at recognising faces and shapes and making connections between images, heralding a new age of visual search that could transform the way we interact with the world around us. Have you ever searched Google maps for a destination, asked it for directions, then walked off in completely the wrong direction? I have, plenty of times - and I'm way down the street before the arrow on my phone jolts into the right position telling me I'm getting colder, not hotter. Of course, being a man, I have to walk on a few more metres before finally admitting my mistake and effecting the 180-degree "swivel of shame". And this always seems to happen when I'm late for a meeting, which is quite often.
