Using Front Camera in Vuforia Engine

I'm trying to create an AR experience that works with both front and rear cameras (where available). I want to switch between them just like you would with a default camera app.

Does Vuforia Framework Support Front Camera, and does someone integrate Vuforia with other face tracking AR framework before and how was the experience ?

Vuforia has deprecated the front camera in his newer versions (8.x and newers).

You can use older versions of unity to force use vuforia 7.x

In my case, I used Unity 2018.2.12 and downloaded vuforia 7 here:

Vuforia front camera setting

In your AR camera settings, you will find this option ranging from CAMERA_DEFAULT, CAMERA_BACK and CAMERA_FRONT.

To access the camera via script, Vuforia has explained in detail in this page: https://library.vuforia.com/articles/Solution/Working-with-the-Camera

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Vuforia;

public class CameraController : MonoBehaviour
{
    private bool lightOn = false;
    private bool frontCamera = false;

    public void CameraChange()
    {
        if (!frontCamera)
        {
            RestartCamera(CameraDevice.CameraDirection.CAMERA_FRONT);
            frontCamera = true;
            Debug.Log("Using Front Camera");
        }
        else if (frontCamera)
        {
            RestartCamera(CameraDevice.CameraDirection.CAMERA_BACK);
            frontCamera = false;
            Debug.Log("Using Back Camera");
        }
        else
        {
            Debug.Log("No camera status available.");
        }
    }

    private void RestartCamera(CameraDevice.CameraDirection newDir)
    {
        CameraDevice.Instance.Stop();
        CameraDevice.Instance.Deinit();
        CameraDevice.Instance.Init(newDir);
        CameraDevice.Instance.Start();

        // Periodically check to see if still needed
        VuforiaUnity.OnPause();
        VuforiaUnity.OnResume();
    }
}
