This is not a simple question. The answer *it depends* will not be helpful either. So I would suggest that (if you have not already) you look into the book *Diffusion of Innovations* by Everett Rogers. You can also look at different type of *preparedness*. In any case you must have some kind of model of application that people can understand - you could look at research in Prototyping and Mock-Ups for inspiration on how that could be done. But your question is too generic - because you need to explore *what is the point of your research* and *what do you want to achieve* OR *what do you wish to inquire into specifically?*. If you do not have a specific research question - then the answer to your generic question would be *any-way you feel like it*. But that is perhaps not what you had in mind.

Dear Aarash, after you have followed the precious suggestions of Peter, I propose you to deepen some methodologies very helpful to explore preferences/acceptance of users. One of them is the Discrete Choice Experimen. Additionally, if you would like to know more deeply the opinions or the feelings of users, some qualitative methods (focus group or word cafè) would be helpfull as well.

Dear Peter and Anna Maria, Thank you so much for valuable comments. I will focus on references and solutions you mentioned in your comments.

Cheers,

Aarash
