How to reach every bone in the hand when they collide with an interactable object?

Hi everyone I am using Leap Motion and I want to reach the every node in the hand when they collide with something. Because I am working on a haptic glove project where you feel objects with your hand in Virtual Reality. I need some function similar to onTriggerEnter for each node in the hand because in reality I want to link every point in hand with vibration motors therefore when you touch something with your thumb unity will only send signal to vibration motor in thumb.

I looked Extended Finger Detection Script and the others but couldnt find any helpful thing. In play mode when left and right hand instantiated. There are Left and Right interaction Contact Bones. This is what I want to reach as I show in the screenshot.

If I can manage to reach the contact bones from the script and know which bone is for which node I can check whether they collide something or not. If they collide, I will send signal to vibration motor in that point.

What should I do, what do you reccomend? I am really nervous about this because the deadline is near. Thanks for your help.

I found the solution. In case anyone wondering or reading this forum idk can apply this solution. Again the case was reaching each finger collision event with objects.

Actually changing a few code in "Interaction Hand" script created the solution. I wrote a script which handles fingerCollisions.

public class fingerCollisionScript : MonoBehaviour
{
    public int boneIndex;
    private fingerCollisionController controller;
    private bool collisionOccured;
    private Collider collidedObject;
    private Collider m_Collider;

    // Start is called before the first frame update
    void Start()
    {
        GameObject controllerObj = GameObject.FindGameObjectWithTag("fingerCollisionController");
        m_Collider = this.GetComponent<Collider>();

        if (controllerObj)
        {
            controller = controllerObj.GetComponent<fingerCollisionController>();
        } else
        {
            Debug.LogError("fingerCollisionController could not be found");
        }
    }

    // Update is called once per frame
    void Update()
    {
        if (collisionOccured && !m_Collider.bounds.Intersects(collidedObject.bounds))
        {
            Debug.Log("Bounds intersecting");
            controller.boneNotCollided(boneIndex);
            collisionOccured = false;
        }
    }

    public void setIndex(int index)
    {
        boneIndex = index;
    }

    public void OnTriggerEnter(Collider collision)
    {
         controller.boneCollided(boneIndex);
         collisionOccured = true;
         collidedObject = collision;   
    }
    
}

and then added these lines into interactionHand Script:

contactBoneObj.transform.position = bone.Center.ToVector3();
      contactBoneObj.transform.rotation = bone.Rotation.ToQuaternion();
       
      // Custom: adding fingerCollisionScript
      contactBoneObj.AddComponent<fingerCollisionScript>();
      contactBoneObj.GetComponent<fingerCollisionScript>().setIndex(boneArrayIndex);
       Index(boneArrayIndex);

And finally wrote a controller which handles the colliding situation of each bone.

public void boneCollided(int boneIndex)
    {
        boneArray[boneIndex] = 1;
        int[] motorsToTurnOn = boneMotorMap[boneIndex];
        for(int m=0; m <motorsToTurnOn.Length; m++)
        {
            motorArray[motorsToTurnOn[m]] = 255;
        }
    }

    public void boneNotCollided(int boneIndex)
    {
        boneArray[boneIndex] = 1;
        int[] motorsToTurnOn = boneMotorMap[boneIndex];
        for (int m = 0; m < motorsToTurnOn.Length; m++)
        {
            motorArray[motorsToTurnOn[m]] =0;
        }
    }

You are welcome
