Human Computer Interaction (HCI) for Undergraduate Design students [on hold]

I will teach an undergraduate course in HCI to design students and It will be theoretical at the first and second exam where they will get in-depth in understanding the user and the behaviours alongside the UX. I'm thinking of doing a project for the final where they will need to develop a hypothetical physical interface from a-z. does that make sense and if not it will be great to hear some suggestions.

Thank you!
