I believe the VR920 and the Icuiti are the same device. If so, you can use our Icuiti plugin that ships with Vizard. Here is some sample code that will connect to the HMD and link the orientation data to the viewpoint:
Code:
import viz
viz.go()
#Add icuiti sensor
icuiti = viz.add('icuiti.dls')
#Link sensor to viewpoint
viz.link(icuiti,viz.MainView)
