Can ARKit use both cameras? The Ultimate Guide for ARKit Developers

Estimated read time 4 min read

ARKit is a powerful augmented reality framework developed by Apple. It allows developers to create interactive and immersive experiences that blend virtual objects with the real world. But what if you want to use both cameras on your device to enhance the user experience? In this guide, we will explore whether ARKit can use both cameras and how to do it effectively.

Using Both Cameras in ARKit

ARKit uses the camera input from a single camera to track the position of virtual objects in the real world. However, with the introduction of dual-camera devices such as the iPhone XS and later models, developers can take advantage of both cameras to create more advanced and interactive experiences.

One way to use both cameras is by using depth sensing. Depth sensing allows ARKit to track the distance between virtual objects and the real world. This information can be used to create more realistic and immersive experiences, such as virtual objects that interact with their environment in a more natural way.

Another way to use both cameras is by using stereo vision. Stereo vision allows ARKit to track depth and distance between virtual objects and the real world, and also detect changes in movement and orientation. This information can be used to create more advanced interactions between virtual objects and the user.

Case Studies

Let’s take a look at some real-life examples of how both cameras are being used in ARKit.

  1. Virtual Trying On: A fashion app called "Virtual Trying On" uses both cameras to allow users to try on clothes virtually before making a purchase. The app tracks the user’s body using depth sensing, and then overlays virtual clothing onto the user’s image. This allows users to see how the clothing would look on them in real-time, without having to physically try it on.
  2. Pokemon Go: The popular augmented reality game Pokemon Go uses both cameras to track the user’s location and surroundings. The game overlays virtual creatures onto the real world, allowing users to catch and battle them in their surroundings. This creates a more immersive experience for the user.
  3. Snapchat Filters: Snapchat filters use both cameras to create fun and interactive filters for photos and videos. For example, the "Lens" filter uses depth sensing to add 3D effects to the photo or video, making it look like the object is popping out of the screen.

The Benefits of Using Both Cameras in ARKit

Using both cameras in ARKit has several benefits:

  1. Improved Accuracy: By using depth sensing and stereo vision, ARKit can track virtual objects more accurately and in real-time. This allows for a more natural interaction between the user and the virtual object.
  2. Enhanced Realism: With both cameras, ARKit can create more realistic and immersive experiences by overlaying virtual objects onto the real world.
  3. Increased Engagement: By creating more interactive and immersive experiences, users are more likely to engage with the AR app or game.
  4. Better User Experience: Using both cameras allows developers to create a better user experience by providing more accurate tracking and more realistic visuals.


Can I use both cameras in my ARKit app?

Yes, it is possible to use both cameras in your ARKit app by using depth sensing or stereo vision.

What is the best way to use both cameras in ARKit?

The best way to use both cameras in ARKit depends on the type of experience you want to create. Depth sensing is great for creating realistic interactions, while stereo vision is useful for tracking depth and movement.

Are there any limitations to using both cameras in ARKit?

There are some limitations to using both cameras in ARKit, such as increased processing power requirements and potential compatibility issues with older devices.
