The ClassFlow educational software aims at enhancing classroom interaction with the goal of making students learn more effectively and with greater motivation. It follows a gamification approach that is fun for children and gives them direct feedback on their learning achievements. Teachers can praise students with animations such as flying balloons. The AR/VR course materials can be used, e.g., to explore the bottom of the ocean or space, turning abstract knowledge into an immersive teaching experience. By linking multiple devices, students can compete against each other by holding team competitions.
