Controller Coordinates and Euler angles

[biomech_dave]

Hello! I'm using the Vive for proprioceptive reseach and need to get the coordinates of the controllers. I am new to Python but I tried manipulating the steamvr example like this:

import viz
import vizact
import vizshape
import steamvr

for controller in steamvr.getControllerList():
print "connected"
total = 0
if total == 0:
left_controller = controller
total += 1
else:
right_controller = controller

print right_controller.getPosition()

I get an error that 'right_controller' is not defines. I'd like to get the Euler angle and position output continuously while the programming is running. Any thoughts would be helpful.

Thanks!
Dave

If both controllers are connected, try the following:

rightController = steamvr.getControllerList()[0]
leftController = steamvr.getControllerList()[1]

def printData():
	print 'pos right:',rightController.getPosition()
	print 'pos left :',leftController.getPosition()
	
vizact.onupdate(0,printData)

However, I would recommend using vizconnect to connect to the Vive in Vizard. In the preset configuration list there is a 'HTC Vive' option. That connects to all hardware and renders a hand for each controller. The transport allows you to navigate using the controller track pad. You can also get the controller position in your own script:

rightTracker = vizconnect.getTracker('r_hand_tracker').getRaw()
leftTracker = vizconnect.getTracker('l_hand_tracker').getRaw()

def printData():
	print 'pos right:',rightTracker.getPosition()
	print 'pos left :',leftTracker.getPosition()
	
vizact.onupdate(0,printData)

Great! That helped a lot! I also have the code for the module generated by vizconnect which will help.

Thanks again for the really quick reply.

Cheers,
