This is just one technique that can be used to learn about the physical world, Tenenbaum says. A range of new three-dimensional environments aimed at AI researchers should drive further research in this area (see "A 3-D World for Smarter AI Agents" and "New Tool Lets AI Learn to Do Almost Anything on a Computer"). A team from the University of California, Berkeley, led by Sergey Levine, presented a system that learns about the physical world using a combination of video imagery and experimentation. This offers a way to develop and test simple ideas that might eventually transfer to the real world. This is just one technique that can be used to learn about the physical world, Tenenbaum says.
