Click here to download optical markers, that can be used with ARaction:


  • When printing them, make sure that page scaling is deactivated!
  • After you placed them on the floor, make sure they do not move anymore.

There are two usecases for optical markers in ARaction:

  1. When using ARaction in a difficult environment (e.g. outdoors in a forest) you can enable optical marker relocalisation for your presentation. Optical markers are very robust and can be recognized even under challenging light conditions – on the other hand the positioning of your markers will be less exact as with the default localisation method.
  2. When you want to import markers with their position from one presentation into another and those presentations do not use the same ADF scan file, an optical marker will be used as calibration point to recalculate the position of all imported markers.
