David,
I don’t see how they can ever be success criteria - since we would have to specify physical dimensions — and we don’t know the device size.   are you thinking we assume this is a tablet or something and base all recommendations on that?   With some set resolution?        Or do we assume that we can rescale content to force a physical size regardless of screen size and resolution? 

What are your thoughts?

The principles of enough space to click without hitting something else, and a big enough target  seem foundational. The word "adequate" is pretty subjective, I wonder if there is a range of measurements we can provide as were discussed at the face to face.
