Question data glove navigation

Hi, im trying to use 5dt data glove to navigate the 3D environment. i try to use the cameraHandler function, but in that function i cannot call the gesture method. below i try to show what is my idea. anyone can help me how can i navigate the 3D space. i need help as soon as possible.
the main objective that is i want try to do is if i use the data glove and i give the instruction by using index finger point the view can move forward.

any one can help me?!
thanks,
may god bless you.

Code:
import viz
import hand
viz.go()

#Identify the data glove's port.
PORT_5DT = 1

#Add the 5DT sensor
sensor = viz.add('5dt.dls')

##Create a hand object from the data glove
glove = hand.add(sensor,hand.GLOVE_5DT)

##Place the hand in front of the user
glove.rotate(0,-45,0)
viz.MainView.translate(0,0.3,-0.4)
glove.setPosition( 0.03, 0.09, 0.5 )

#Initialize world
viz.clearcolor( viz.GRAY )
ground = viz.add( 'tut_ground.wrl' )



#Add an array with all the gesture names from the 5DT user's manual.
gestureName = ['Fist', 'Index finger point', 'Middle finger point', 
'Two finger point', 'Ring finger point', 'Ring-Index finger point', 
'Ring-middle finger point', 'Three finger point', 'Little finger point', 
'Index and little finger point', 'Little-middle finger point', 
'Not ring finger point', 'Little-ring finger point', 
'Not middle finger point', 'Not index finger point', 
'Flat hand', 'Undefined']

def mytimer(num):
	gesture = int(sensor.get()[-1])
	
	if gesture == 1:
		#Index finger point
		ground.view.move( 0, 0, 1)
	if gesture == 0:
		#Fist
		ground.view.move( 0, 0, -1)

There are some problems with your timer. First off, you never register your timer with Vizard, so it is never called. Second, you are incorrectly accessing the viewpoint. Try replacing your mytimer function with the following code:
Code:
def UpdateView():
	gesture = glove.getGesture()
	
	if gesture == hand.GESTURE_INDEX_FINGER:
		#Index finger point
		viz.MainView.move( 0, 0, 1*viz.elapsed())
	elif gesture == hand.GESTURE_FIST:
		#Fist
		viz.MainView.move( 0, 0, -1*viz.elapsed())
		
		
vizact.ontimer(0,UpdateView)

Here's a modified version of the script that will always place the glove in front of the user. You can use other gestures to control left/right movement. Or, if you have an orientation tracker device, such as the Intersense IneriaCube, you could use that to steer the viewpoint as well.
Code:
import viz
import hand
viz.go()

#Identify the data glove's port.
PORT_5DT = 1

#Add the 5DT sensor
sensor = viz.add('5dt.dls')

##Create a hand object from the data glove
overlayView = viz.addView()
overlayView.setScene(4)
overlay = viz.addWindow(pos=(0,1),size=(1,1),clearMask=viz.GL_DEPTH_BUFFER_BIT,view=overlayView)
glove = hand.add(sensor,hand.GLOVE_5DT,scene=4,pos=(0,1.5,1.5),euler=(0,-90,0))

#Initialize world
viz.clearcolor( viz.GRAY )
ground = viz.add( 'tut_ground.wrl' )

def UpdateView():
	gesture = glove.getGesture()
	
	if gesture == hand.GESTURE_INDEX_FINGER:
		#Index finger point
		viz.MainView.move( 0, 0, 1*viz.elapsed())
	elif gesture == hand.GESTURE_FIST:
		#Fist
		viz.MainView.move( 0, 0, -1*viz.elapsed())
	
		
vizact.ontimer(0,UpdateView)

i'm so sorry if i bothering you.
i hope you can help me to solve my problem.

#Identify the data glove's port.
PORT_5DT = 1

#Add the 5DT sensor
sensor = viz.add('5dt.dls')

##Create a hand object from the data glove
overlayView = viz.addView()
overlayView.setScene(4)
overlay = viz.addWindow(pos=(0,1),size=(1,1),clearMask=viz.GL_DEPTH_BUFFER_BIT,view=overlayView)
glove = hand.add(sensor,hand.GLOVE_5DT,scene=4,pos=(0,1.5,1.5),euler=(0,-70,0))

#Initialize world
viz.clearcolor( viz.GRAY )
ground = viz.add( 'tut_ground.wrl' )

def UpdateView():
	gesture = glove.getGesture()
	
	if gesture == hand.GESTURE_INDEX_FINGER:
		#Index finger point
		viz.MainView.move( 0, 0, 1*viz.elapsed())
	if gesture == hand.GESTURE_FIST:
		#Fist
		viz.MainView.move( 0, 0, -1*viz.elapsed())
	if gesture == hand.GESTURE_TWO_FINGER:
		#Two finger point
		viz.MainView.move( 1*viz.elapsed(), 0, 0 )
	if gesture == hand.GESTURE_LITTLE_FINGER:
		#Tumb up
		viz.MainView.move( -1*viz.elapsed(), 0, 0 )

If you want to turn left/right instead of moving left/right using the following code:
Code:
#Turn right
viz.MainView.setEuler(90*viz.elapsed(),0,0,viz.HEAD_ORI,viz.REL_LOCAL)

#Turn left
viz.MainView.setEuler(-90*viz.elapsed(),0,0,viz.HEAD_ORI,viz.REL_LOCAL)
I'm sorry, I don't understand your second question.

for the second question is i want create a new gesture.

5dt glove have application to create new gesture.so i create the new gesture to make the navigation in vizard.

i create the gesture and i saved it as EDIT. the gesture is like this thumb= unflexed index=unflexed middle=flexed ring=flexed and little=flexed.

so i try to call the "edit" gesture. like this
Code:
gesture == hand.GESTURE_EDIT:
		#Tumb up
viz.MainView.setEuler(-90*viz.elapsed(),0,0,viz.HEAD_ORI,viz.REL_LOCAL)
but i was error.
i hope you can help me.
thanks a lot
