Introducing PI VR Landmarks! This app was developed to accompany a book, Encyclopædia Britannica: Landmarks. In the book, learn about natural and human-made landmarks around the world, from ancient to modern. With this app, you can bring the knowledge from the book to life by seeing ten landmarks from around the world.

To access the app, download PI VR Landmarks, available on the App Store or Google Play. Direct links to the store locations are found below:


  1. To use the app, you will need a VR viewer, such as the one packaged with your book or set of books. If that viewer has been lost or damaged, you can try another VR viewer. For the viewer included with the book, set up the viewer as shown on page 1 of the book.
  2. Launch the app. You may be asked to calibrate your viewer by scanning the QR code found on the bottom of the viewer itself. You will be able to change your viewer settings later in the options menu.
  3. The first time you use the app, you will be prompted to scan the QR code found on page 1 of the book to verify your possession of this book.
  4. You will see a double image of an interactive map on your phone. Insert your smartphone into the front compartment of the VR viewer. The line between the two images should line up with the notch at the center point of the viewer, between the two lenses. If your screen seems blurry, make sure the smartphone is aligned precisely with the center of the viewer. Adjusting the phone left or right a few millimeters can make a big difference. The tilt of the viewer and the phone can also affect how the screen looks to you.
  5. Look around to explore! PI VR Landmarks does not require a lever or remote control. You control each interaction with your gaze. When you see a loading circle, keep your gaze focused until it loads fully to access videos, slideshows, and games.
  6. Gaze at the X to close out of video, slideshow, or game screens.

Does the book work with all smartphones?

Click Cancel; it should not prevent you from running the app successfully.
