Tips for getting the best performance Augmented Reality is still a new technology, but you can do a few things to make sure you have the best experience of AR that you can:
The black Flash screen can take a few seconds to load. Please be patient
Ensure that your webcam is not being used by any other applications
Close any large applications that you have open
Mid-range lighting is most suitable. Not a dark room or with bright lights behind you
Don't cover the marker or have heavy glare from a light on the marker
Try holding the marker still and at various angles
Don't move the marker in quick or jerky movements
Smartphones: if you don't have access to a printer you can still view and display the marker using your BlackBerry, iPhone or smartphone by accessing this link in your mobile browser http://www.lewispr.com/ar/marker.jpg
