“Climate change in the forest” is the big topic. There are currently two paths available in the app in the Teutoburg Forest Eggegebirge Nature Park, which can be followed via GPS track (without signs in the forest) and where different stations address the topic of climate change and forests. Acoustic signals indicate the imaginary stations. 3D animations, representations with augmented reality and quizzes complement the topic and make the hikes come alive. At the end of a hike there is a diploma for the achievement to download.
