1. Facebook is really buying into Augmented Reality
Where chatbots and virtual reality (VR) were central to last year's F8, augmented reality (AR) was Zuckerberg's big push this year.
Zuckerberg came armed with barbed comments for rival social network Snapchat during his Tuesday morning keynote, describing augmented reality use cases like Pokemon Go or Snapchat style "face filters" as "primitive versions of these use cases on our phones and cameras". Facebook released its own set of facial filters and augmented reality effects last month with Facebook Camera, but Zuckerberg says this was only stage 1.0.
"Photos and videos are becoming more central to how we share than text, so the camera needs to become more central than the text box in all of our apps," he said.
Facebook's strategy to win in this space revolves around giving users the ability to create their own personalised effects and filters. "Today we are going to start building this platform together and make the camera the first mainstream augmented reality platform," Zuckerberg said.
