Robots and humans see the world differently – but we don't know why

A few years back, artificial intelligence reached the point at which it could recognise objects in images and answer questions about them. But it turns out that when an AI looks at an picture, it sees totally different things to humans. In experiments conducted at Facebook and Virginia Tech, researchers found significant differences between what humans and computers looked at when asked a simple question about an image. Lawrence Zitnick and a team of computer vision experts first asked human workers on Amazon's Mechanical Turk platform to answer basic questions about a photo. The photo began blurred, but the worker could click around to sharpen it in different areas.
