"Some of these effects are going to be fun, and others are going to be useful", he said. But, note that Zuckerberg is now talking mostly about things you see in the app - not things you'd see with AR glasses, which he says may come eventually. The platform, which has a strong mobile focus but also desktop capabilities, provides a suite of tools for artists, designers and developers to build augmented reality (AR) apps for Facebook.
Facebook also announced a bevy of updates to Messenger, its increasingly independent messaging app.
At Facebook's F8 annual developer conference, Facebook and Snapchat's cold war heated up.
CEO Mark Zuckerberg said in a keynote speech that he no longer viewed glasses and spectacles - such as those created by Alphabet Inc., Microsoft Corp., and Snap Inc.
We're not able to do those things just yet but Facebook users will have more options when it comes to sharing photos and videos like pixilated blue beards, stickers and 3-D text.
Facebook also launched a virtual world, called Facebook Spaces, created to let users of its Oculus Rift VR headset hang out with their friends wherever they might be. Facebook Spaces will come with Messenger video calling feature to call a friend in the real world.
Facebook is teaming-up with Udacity to create custom training programmes for Developer Circles. Users can build an avatar and use Spaces to "spend time" with up to three other avatars.
Building on the launch of chatbots on Messenger at F8 previous year, Facebook announced the new Discover tab, to find recently used bots, popular "experiences" and search for businesses.
The F8 2017 is finally here. The company claimed that Workplace is being used by 14,000 businesses. However, Zuckerburg also mentioned that the new AR tools will not magically transform users' experience. Facebook relies on users to flag content that's illegal or violent. The company is said to officially launch the standard version of its Workplace later this year.
This interaction happens via chat-bots, which were rolled out at last year's developers' conference.
Facebook-and tech journalism-seems to have missed the irony of building an application that allows people to interact in ways they used to before Facebook was invented.
