The promise of augmented and virtual reality was a big focus of Facebook’s annual conference for developers Tuesday. CEO Mark Zuckerberg kicked off the gathering by talking about augmented reality tools he envisions on Facebook. Augmented reality involves the overlay of computer-generated images into real-world surroundings.
Mr. Zuckerberg said new phone-based applications might let you create a three-dimensional scene from a single two-dimensional photo or splatter the walls of your house with colorful digital art. (You’d see the digital additions by looking “through” your phone at the augmented physical world.)
