Object Move From Hololens Player Direction

Hello, Community!

I would be very grateful if I could answer this question.

I did not speak English and I used Google Translator.

I am developing an App using Hololens and Unity.

Using a gesture to move the object in the direction
Goal.

We have confirmed that the y and z axes are now properly implemented and distributed to Hololens, so that they work normally.

I made a lot of effort, But the x-axis does not know the correct answer.

Here is my code:

    Vector3 heading = this.gameObject.transform.position - XVeil.Instance.HeadTransform.position;
    var distance = heading.magnitude;
    var direction = heading / distance;

    if (args.Position.x > 0.8 || args.Position.x < -0.8)
    {
       // This is Problem
        Vector3 dir1 = this.gameObject.transform.position - Vector3.zero;
        Vector3 dir2 = this.gameObject.transform.position - XVeil.Instance.HeadTransform.position;
        float angle = Vector3.Dot(dir1, dir2);
        Vector3 moveVector = args.Position - oldPosition;
        Vector3 newPos = Quaternion.Euler(0, angle, 0) * moveVector;
        this.gameObject.transform.position += newPos * offset;
        oldPosition = args.Position;
    }
    else if (args.Position.y > 0.8 || args.Position.y < -0.8)
    {
        // this is OK
        Vector3 newPos = args.Position;
        newPos.x = 0f;
        newPos.z = 0f;
        this.gameObject.transform.position += newPos * offset;
    }
    else if (args.Position.z > 0.8 || args.Position.z < -0.8)
    {
        // this is OK
        this.gameObject.transform.position += direction * args.Position.z * offset;
    }
