The Participant Number agreed on with our supervisor is N>=15.

Pre Study We conducted a pre-Study with n<5 users to make out any inconsistencies or design mistakes in our study. Lessons learned are the following:

• Video Recording of the subject is not meaningful, therefore we will refrain from doing that in order to facilitate a more pleasant test experience for our participants
• Test is conducted between-subjects, learning should be prohibited as compared to testing Morae as well as the OBS-Tool
• Instructions concerning the configuration of OBS-Studio as well as the Morae-Recorder should be provided to the participants
