>The thing is, it's actually really hard to judge quality of a design(takes a bachelor degree in Industrial Design and masters in related field and a few studies like the one in question to objectively evaluate a design).

Horse hockey. Spend a couple years in Quality Assurance with your eyes open. It:s trivial to seperate wheat from chaff. The key that your Industrial Design might give you insight on is the fact that Industry has decided unilaterally that cost to produce > joy of end user in use. I.e. if it's cheaper to make and sell, it's higher Quality, rather than it's damn good, now lets streamline it.

Yes, your process weighs into it, but I assure you, the cognitive load of a haptic interface vs a touchscreen is so much lower it's absurd to even try to compare. If you really care about the end user, you take the time to get them buttons, and don't distract them with touchscreen finicky BS.
