## Build immersive AR in the platform of your choice

For the first time, our world-leading computer vision technologies are available as libraries and SDKs for a wide range of platforms and creative tools. Developers of all stripes can now build magical AR content using their favorite development environments and languages. With **broad support for both web and native mobile platforms**, it's now possible to deliver awesome AR experiences to more end-users than ever before.

### Face tracking

Face tracking uses computer vision to build an understanding of a users’ face: recognising key landmarks such as the eyes, mouth, nose, and chin. By understanding where these landmarks are, we enable you to build interactive experiences by attaching 3D models and 2D images to them.

### World tracking

World tracking allows us, through the phone camera, to build an understanding of a user’s environment, and place digital content on to flat surfaces. The position of content placed in the world is often set to remain fixed, allowing users to walk around and view it from any angle, making it feel like it is part of the room with you.

### Image tracking

Printed materials such as posters and magazine covers can be uploaded to ZapWorks to make ‘Target images’. Using our image tracking technology, through the phones camera, you can bring these materials to life.
