Travis,
I see your point. I’m just curious. You only want research subjects to know as much as they necessary to generate the data you need.
At the same time, we are all designers here and, hopefully, we want to help choto have the best thesis possible. My master’s thesis was similar in that my goal was to start a business and bring products to market.
If that is the route he is going, I may have some insights for him that go beyond what this survey can deliver. Not that I know everything, far from it.
By the way, Choto, I really like your sketch/stich experiments. Increasingly, that is how some of my work is being done, depending on the complexity of the product of course.
