What is augmented reality & how does it work?
Simply put, augmented reality is an overlay of digital content in the real world through a screen. AR has already delighted millions in the form of Snapchat’s animated emojis, Instagram’s 3D stickers, and Pokémon Go. The accessibility and simplicity of markerless AR are two of the huge advantages it has over VR, and now Apple and Google have opened it up to the masses via ARKit and ARCore respectively.
Using a phone or tablet’s camera and motion sensors, AR works by finding points in the environment, then tracking them as you move the device. It doesn’t create a 3D model of a space, but it can “pin” objects to one point, realistically changing their scale and perspective. It can also find flat surfaces, which is great for placing digital props into the real world.
