Make touch drag more intuitive/smooth for AR-Application

I am currently working on an app to augment pictures on a vertical plane. Once the vertical plane is placed, the user is able to put an object on the plane. The placed object can be selected and dragged on touch - so far everything works fine.

 void MoveSelected()
     {
         Vector3 curPos = cam.ScreenToViewportPoint(Input.touches[0].position);
         Vector3 lastPos = cam.ScreenToViewportPoint(Input.touches[0].position - Input.touches[0].deltaPosition);
         Vector3 touchDir = curPos - lastPos;
 
         touchDir.z = 0;
 
         curSelected.transform.position += verticalPlane.transform.TransformDirection(touchDir);
     }

However, the dragging is not very intuitive and i would like to make it more smooth. For example, if i scale down the object, dragging becomes very slow. Is there any way to improve my method?

Im using latest ARFoundation, Unity and im testing on Pixel 2.

Thanks
