We added a script so that our studies could be conducted in a consistent manner.
Minor changes were made to the consent form to fit the context of our study, such as adjusting the time the experiment should take and what the participant should expect to do.
We made separate questionnaires for each one of our interfaces and also a post study one. Questions were also reworded for clarity.
We compiled a list of all the comments on both videos for the participants to use during the search for the comments.
