Get your Minority Report or Skynet references ready, researchers at the University of Cambridge are working on a way to use AI and drone surveillance to spot violent behavior in crowds. The research paper even has a cool sci-fi name: Eye in the Sky. The project uses an inexpensive Parrot AR 2.0 drone to watch crowds of people from above. Then it uses AI to identify people in violent poses (the paper mentions strangling, punching, kicking, shooting and stabbing). It's important to note that the researchers didn't fly a drone around to detect real violence -- The Verge reports it shot its own video clips using volunteers.

Controlling artificial intelligence devices by voice will come soon said AI expert Neil Jacobstein. Artificial intelligence is set to transform the world, the audience at a Christchurch conference on the future was told. Artificial intelligence (AI) "allows us to expand the range of the possible, to do things we never thought we could do before," said Neil Jacobstein who chairs the artificial intelligence and robotics track at Singularity University, a think tank based in California. "AI is not just "faster, better, cheaper, it's different," he said. Students will soon have personalised one-to-one AI tutors that will follow them through formal education and into adult life, he said.
