how to reduce motion sickness with Oculus rift+logitech driving force

[hzhao]

Hi,

I am setting up my Oculus rift DK2 with Logitech driving force GT. To use these two, I combined the two demo codes for Oculus and joy stick control (attached below). It works. But I don't feel well when I use this setup because of the very strong motion sickness. I used the position tracking from Oculus. Could anyone give me some help to improve it? reduce the motion sickness? Thanks.

the code I used:

hmd = oculus.Rift()

# Get list of joystick device information
dinput = viz.add('DirectInput.dle')
devices = dinput.getJoystickDevices()
joy = dinput.addJoystick(devices[selected])
joy.setDeadZone(0.05)


# Check if HMD supports position tracking
supportPositionTracking = hmd.getSensor().getSrcMask() & viz.LINK_POS
if supportPositionTracking:

# Add camera bounds model
camera_bounds = hmd.addCameraBounds()
camera_bounds.visible(False)

# Change color of bounds to reflect whether position was tracked
def CheckPositionTracked():
if hmd.getSensor().getStatus() & oculus.STATUS_POSITION_TRACKED:
camera_bounds.color(viz.GREEN)
else:
camera_bounds.color(viz.RED)
vizact.onupdate(0, CheckPositionTracked)

# Setup navigation node and link to main view
navigationNode = viz.addGroup()
HMDviewLink = viz.link(navigationNode, viz.MainView)
HMDviewLink.preMultLinkable(hmd.getSensor())

# Apply user profile eye height to view
profile = hmd.getProfile()
if profile:
HMDviewLink.setOffset([0,profile.eyeHeight,0])
else:
HMDviewLink.setOffset([0,1.8,0])
