Marker for Augmented Reality

GreyMapp uses AR-Kit (iOS) and ARCore (Android) for the augmented reality capabilities. In case your device doesn’t natively support these techniques there is a fallback using a marker.

You can download the marker here: Brain Marker

In order to use the marker, print it with your favourite pdf reader. Make sure that when you print it, you will use no scaling or resizing (print at 100% size).
