Apple recently introduced an upgrade to their “personas” for the Vision Pro headset. A persona is essentially an avatar. People who play video games, use phone messaging apps, or AR/VR are already familiar with these types of avatars – either realistic looking or character looking.
The spacial personas developed for the Apple Vision Pro, however, are more 3D realistic based on facial-recognition scans done by the headset. When in use, such as during a Facetime call, you can see the other person right there in the room with you. And you'll see his/her body language and expressions, etc.
Now, before we get all excited, remember that it's not perfect just yet. The body appears more like a ghostly floating head and torso. Not quite Blair Witch Project creepy, but it's not 100% perfect. But it's a step in the right direction toward 3D realistic virtual communications.
Personas are avatars that look like their users. In that sense, they are similar to Memojis on iPhone. The primary difference is that Personas look way more lifelike. Users set up the realistic avatar by allowing the Vision Pro to perform a 3D face scan, which it uses to create a digital likeness. The avatar appears in a movable 2D tile during FaceTime calls or other multiuser activities, like SharePlay. The Vision Pro uses AI to sync the avatar to match the user's head, mouth, and hand movements. The effect is like having a floating animated portrait in your session space.
