Google announces health tool to identify skin conditions

Google's latest foray into health care is a web tool that uses artificial intelligence to help people identify skin, hair, or nail conditions. The company previewed the tool at I/O today, and it says it hopes to launch a pilot later this year. People can use their phone's camera to take three pictures of the problem area -- for example, a rash on their arm. The tool then gives a list of possible conditions from a set of 288 that it's trained to recognize. It's not intended to diagnose the problem, the company said in a blog post.
