We are currently planning two case studies to further examine how we want to design the breaks. We are hoping that we can visit ETH Zürich, where there is a break after 45 minutes of lecture. Furthermore, we would like to go to a university that offers a "Pausenexpress". The "Pausenexpress", if booked by the professor, visits lectures for a short active break after 45 minutes. We would like to talk to the persons responsible and to some students to get some different opinions on breaks during lectures and to gain more knowledge abot what is working and what is not. This should help us to create the optimal break for our project.
