By mask we’re not talking about using something like an animoji to replace your face, but rather as you can see in the video below that Noshiro uploaded onto Twitter, he has somehow managed to hide his face completely (save for his eyes and mouth), allowing users to see through his face and into the background behind him.

Exactly how he went about doing so is anyone’s guess as the developer has for now decided to keep mum about it. However according to Engadget, when one person asked if the trick involved pre-recording the background first, the developer admitted that was part of the trick. We’re not sure what kind of practical applications such an app might have, but it does show what kind of potential the TrueDepth camera system has aside from Face ID.
We expect that eventually more apps will be released that will take advantage of the technology in more practical ways, but for now it is interesting to see what it can do.
