In order for Face ID to work on the iPhone X, Apple had to create a pretty complex setup that they are calling TrueDepth, which is basically an array of cameras and sensors that effectively help to map the user’s face properly in order to authenticate them. This is also used in the Animoji feature, but now it looks we have another use for the TrueDepth system.

Developed by Washington University computer science graduate Nathan Gitter, he has created a game for the iPhone X called Rainbrow which basically uses the TrueDepth camera to play. How it works is that gamers will use their eyebrows to move an emoji face up and down the screen to collect stars, while avoiding other emojis.

As you can see in the video above, raising one’s eyebrows will move the emoji upwards, while keeping their face neutral will maintain their position, and furrowing your brows will make your emoji character jump down. We reckon it will probably be a rather tiring game and wouldn’t be surprised if you walked away with some muscle cramps, but at the same time it is a pretty clever idea and a great way to leverage the TrueDepth system.

Rainbrow is not the first app to use the TrueDepth system and ARKit. Previously we have seen a glasses maker use the system to help recommend frames for its users.
