Head tracking logging & realtime data

Hi, two questions -

First off, with the work we'll be doing, it'll be useful if we can keep track of where the person is and where their head is pointed during the trial. What's the best way to do this? If it doesn't exist specifically, I can write the code, but I can't figure out where to start.

Also, is it possible to get head position & rotation data during a simulation, and to make the simulation itself transparent (as in, the person sees the computer desktop instead of the 3D visualization). I ask because I'm thinking about writing the necessary mouse control and connector code to make a sort of VR interface to Google Earth and/or Street View, or something of that sort.

Thanks for any help!

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
You can either completely hide the Vizard window, or minimize it. Here is some code that can do both
import win32gui

#This will completely hide the window

#This will just minimize the window to the task bar
