Here you want a simple marker so some simple options are:

  1. ARToolkit Simple markers like Hiro KanZI marker (it's an open source and completely free AR Library):

  1. Using Vuforia, you can try "Frame Marker". Vuforia provides more than 500 simple designs. You can paint it or stick it on your sheet:

FYI: Vuforia and Artoolkit for both Unity packages are available for free. You just have to import it into your Unity project.

I am writing from memory, so it might not be entirely correct.

  • Decide what marker you want to use.
  • Draw it on paper. Note, however, that the Vuforia SDK identifies points of interest in a target image (most often that is corners), so the more detailed a photo, the more points of interest, which is why their samples use high resolution images of e.g. lots of little stones. Drawing something like a square, cross, or some other simplistic marker, does not work very well.
  • Take a photo of it and transfer it to your computer.
  • Download Vuforia's Augmented Reality SDK for Unity.
  • Register on the Vuforia website and add your photo as an Image Target. Then save/download the database unity package they create for you from your image.
  • Also get a licence key.
  • In a blank Unity scene, import the SDK.
  • Add an AR camera prefab.
  • Add an image target prefab.
  • Import the downloaded database package (containing your uploaded image).
  • On the image target inspector, change the behaviour to use your image as the image target.
  • On the AR camera inspector, add your licence key, and specify the image target database.
  • Create or import some 3D model / primitive. Make it a child of the image target, and position it to sit on top of the image target.
  • Make sure the AR camera is looking at the image target.
  • Build the project and run the project, that's about it.

There should be many tutorials online, just google for something like vuforia augmented reality tutorial
