Hi!
First of all, thank you very much for being that spontaneous and signing up for the user evaluation. As said, the overall time effort should not exceed 30-40 minutes.
You can watch the 7min video (https://www.youtube.com/watch?v=qqitzqNhFXM) at any time by yourself. At your chosen time you can join the meeting with me, I can answer some questions which you might have. After that, you will get a link to a form that allows us to get semi-structured feedback that we want to include in the paper.
If you have any questions, feel free to let me know.
Otherwise, see you later.
Momina
