Do you want to track the physical position/rotation of the users head, or the virtual (viewpoint) position/rotation? Either way, your code would look something like this:

#Can be main view or tracking sensor
head = viz.MainView

def GetHeadInfo():
	pos = head.getPosition()
	euler = head.getEuler()
	
	#Do something with pos/euler data
	
vizact.ontimer(0,GetHeadInfo)

You can either completely hide the Vizard window, or minimize it. Here is some code that can do both

import win32gui
SW_HIDE = 0
SW_MINIMIZE = 6

#This will completely hide the window
win32gui.ShowWindow(viz.window.getHandle(),SW_HIDE)

#This will just minimize the window to the task bar
win32gui.ShowWindow(viz.window.getHandle(),SW_MINIMIZE)
