Using highlighter tool with wand

Hi,
I'm trying to convert WorldViz Highlighter tool example code (http://docs.worldviz.com/vizard/Tools_Highlighter.htm) into a script that uses wand as input (rather than mouse scrollwheel) and changes texture of an object. Here's the code:
Code:
import viz
import vizfx
import vizconnect
import vizact
import vizshape

viz.antialias = 4

viz.fullscreen = 1
viz.clearcolor = (0.5, 0.5, 0.5 )

if __name__ == "__main__":
	vizconnect.go('./vizconnect_config.py')
	viz.MainView.getHeadLight().disable()
else:
	vizconnect.go('./multiscript_vizconnect_config.py')

#Add wand
wand= vizconnect.getTracker('r_hand_tracker').getNode3d()
wandInput=vizconnect.getInput('r_hand_tracker')
#Add a sky with an environment map
env = viz.add(viz.ENVIRONMENT_MAP, 'sky.jpg')
dome = viz.add('skydome.dlc')
dome.texture(env)

#Add showroom osgb file
showroom=viz.add('Showroom1.osgb')


for window in viz.getWindowList():
		window.getView().getHeadLight().disable()

#Add video texture
video=viz.addVideo('VisualisationDemoVideo_v2.mov')
video.play()
video.loop()
videowall=showroom.getChild('projection.002')
videowall.texture(video)

#Get a handle to a texture
texture1=viz.addTexture('VisualisationPic.png')

#Get and set highlighter tool
from tools import highlighter
tool=highlighter.Highlighter(highlightOnCollision=False,highlightMode=highlighter.MODE_OUTLINE)
tool.setItems([videowall])

viewGroup=viz.addGroup()
viewGroupLink=viz.link(viz.MainView,viewGroup)
viewGroupLink.preTrans([0, 0, 1])
arrow = vizshape.addArrow(length=0.2, color = viz.ORANGE,parent=viewGroup)
arrowLink = viz.link(wand,arrow,mask=viz.LINK_ORI)
arrowLink.postMultLinkable(viz.MainView)
viz.link(arrowLink,tool)
  
def updateHighlighter(tool):
   
    tool.highlight()

tool.setUpdateFunction(updateHighlighter)

def onHighlight(e):

    if e.new == videowall:
        print 'videowall is highlighted'
        tex1=videowall.getTexture()
        if tex1==video:
            print 'change'
            videowall.texture(texture1)
        else:
            videowall.texture(video)
    
viz.callback(highlighter.HIGHLIGHT_EVENT,onHighlight)

showroom.disable(viz.LIGHTING)

headlight=viz.MainView.getHeadLight()
headlight.disable()

viz.MainView.setPosition(-5,2,-5)
We use wand 2014 local with PPT tracking.
The above mentioned code works, but not the way I want it to work. The beam of the highlighter tool starts from a fixed point and it doesn't follow the main view. How could the beam start point be main view and how would the target follow the wand?
