To be able to use the application correctly, users must also access the AugmentedScience e-book (PDF). The application works by scanning the markers included in these PDF files. When the camera is pointed at the relevant marker, the corresponding augmented reality content will automatically open in the app. No additional button needs to be pressed. Please make sure that the PDF is either opened on another device or printed, and that the marker is clearly visible and sufficiently large for accurate scanning.
