Head orientation data
Hi Jeff,
How does Vizard translate the head direction from the Oculus DK2 to shifts in the view? I need to know the head orientation of participant in the experiment as I already asked you about (http://forum.worldviz.com/showthread.php?t=5834) and i thought that maybe i can get it the way Vizard does. Thanks. |

Are you using a vizconnect configuration file to connect to the Oculus? If so, viewpoint updates are based on parent nodes in the scenegraph. For example if there is both a tracker and a transport in the scenegraph, the final viewpoint orientation in global coordinates is equal to the transport orientation plus the tracker orientation.
To get a handle to the oculus tracker in a vizconnect based application, use the getTracker command with the tracker name defined in the vizconnect GUI: Code:
oculusTracker = vizconnect.getTracker('head_tracker') Code:
view = viz.MainView Code:
def printData(): print 'tracker orientation', oculusTracker.getEuler() print 'view orientation',view.getEuler() vizact.onupdate(0,printData) |
