Two big tech trends dominate Google I/O developers conference

Google diving deeper into virtual reality and artificial intelligence during an annual conference that serves as a launching pad for its latest products and innovations. Virtual reality and artificial intelligence, or "machine learning," will be among the focal points at the Google I/O developers conference, kicking off Wednesday. That has spurred speculation that Google is getting ready to release a virtual-reality device to compete with Facebook's new Oculus Rift headset, as well as the Samsung's Gear VR and the Vive from HTC and Valve. "2016 is already the year of VR," writes CNET's Sarah Mitroff. "[Google] has shown off Cardboard, its low-cost portable VR viewer initiative, for the last two years, and this year we're certain to see new developments."
