In this tutorial, we'll explore the role of Augmented Reality (AR) in mental health treatment. You will learn how to create immersive therapeutic environments using AR technology, and how it can be applied to cognitive behavioral therapy.
What You Will Learn:
- Understanding the basics of AR
- AR in mental health
- Creating a simple AR application for mental health
Prerequisites:
- Basic understanding of programming (preferably in C#)
- Familiarity with Unity Engine
AR overlays digital information onto the real world. It can be used to create immersive therapeutic environments for mental health treatment. For example, AR can be used in exposure therapy by creating controlled environments that patients can interact with.
AR has various applications in mental health, such as in the treatment of phobias, anxiety, and PTSD. It can also be used to enhance mindfulness and relaxation exercises.
We'll use Unity Engine and Vuforia SDK to create a simple AR application. This application will create an immersive environment for relaxation exercises.
First, we need to set up Unity and Vuforia. After you download and install Unity, create a new project and name it AR_MentalHealth.
// Import Vuforia Engine package into Unity
// Go to Assets -> Import Package -> Custom Package, and select the Vuforia package
// Now, enable Vuforia:
// Go to File -> Build Settings -> Player Settings -> XR Settings and check 'Vuforia Augmented Reality'
Next, we'll create an AR Camera and an Image Target (this can be a picture that the AR Camera will recognize).
// Remove the main camera from the scene
// Right-click in the Hierarchy -> Vuforia -> AR Camera
// Right-click in the Hierarchy again -> Vuforia -> Image
// This will create an Image Target
Let's add a 3D object that will appear when the Image Target is recognized.
// Right-click on the Image Target in the Hierarchy -> 3D Object -> Cube
// This will create a cube that appears when the Image Target is recognized
In this tutorial, we've learned about the basics of AR and its applications in mental health. We've also created a simple AR application using Unity and Vuforia.
Next Steps:
- Learn more about AR and its other applications
- Explore other AR SDKs like ARKit for iOS or ARCore for Android
- Experiment with creating different therapeutic environments

Solution: Import a 3D model of a beach scene and attach it to an Image Target.
Exercise 2: Create an AR application that plays relaxing music when a specific image is recognized.
Solution: Attach an AudioSource to the Image Target and set it to play a relaxing music clip.
Exercise 3: Enhance the previous exercises' applications by adding interactivity. For example, change the music volume by moving the recognized image closer or further from the camera.
