Developer and Washington University computer science graduate Nathan Gitter has created an interesting eyebrow-controlled arcade game designed specifically for iPhone X, called Rainbrow, that takes advantage of the new TrueDepth camera system.
By utilizing iOS 11’s new ARKit framework for building augmented reality apps and the new TrueDepth camera system on iPhone X, Rainbrow tracks your eyebrows all the time which allows you to control an emoji character using just your facial expressions.
Frown and your emoji hero goes down. Raise your eyebrow and you’ll move the emoji up. Make a neutral expression and the emoji stays still. It’s as easy as that and works great.
You must dodge enemies and collect as many stars as possible to get a high score. Hit a car, basketball, duck, spooky ghost or some other obstacle and it’s game over. And with a special powerup, your character gains rainbow eyebrows and the ability to destroy enemies in its path.
Here’s Rainbrow in action.
If you’re having difficulty with Rainbrow recognizing your eyebrows, move to an area with more light. Rainbrow uses the TrueDepth camera system on iPhone X to track your eyebrow movements, meaning it cannot be played on devices without a TrueDepth camera system.
The game’s privacy policy states that depth data is only used for gameplay purposes. It’s kept only for the duration of a game session and never uploaded to a server or given to third parties.
Rainbrow is a fun concept that shows off some of the things the TrueDepth camera can be used for beyond standard stuff like Animoji, Portrait Lighting and Face ID. It’s an oddly fun and addicting title that I wholeheartedly recommend you check out yourself.
