Qualcomm teased the prospect of smartphones that learn a couple of years ago, and it's now much closer to making them a practical reality. The chip designer has revealed its next big mobile processor, the Snapdragon 820, will be one of the first that can handle its Zeroth cognitive computing platform. In short, it'll let your phone learn about you (and the world around you) to take action on its own. You should see photo apps that detect whole scenes, security tools that protect against unknown viruses and interfaces that depend more on expressions and head movement than button taps. It gets more ambitious than that, though. Zeroth allows for always-on sensors that detect your surroundings (such as through motion or sound) and help your phone anticipate what you want.
