Remember, Soneira used the 0.6 arcmin resolution of the eye, but that?s for perfect eyesight. Most people don?t have perfect eyesight. I sure don?t. A better number for a typical person is more like 1 arcmin resolution, not 0.6. In fact, Wikipedia lists 20/20 vision as being 1 arcmin, so there you go.If I use 1 arcminute instead, the scale factor is smaller, about 3438. So let?s convert that to inches to see how small a pixel the human eye can resolve at a distance of one foot:12 inches / 3438 = 0.0035 inches

Hiram Says: June 10th, 2010 at 8:21 pmIf you look at or listen to the quote, we will see that Jobs says “around” 10- 12″ and “around 300 pixels” Then others infer the definitive statements, of definitely exceeding all human perception. When I heard that statement, with two “arounds” in it, I interpret that as “being damn close to if not exceeding the limit”. However, when making a statement this vague, you can guarantee the spec nerds will go nuts, once again not getting the point that the exact specs are not what is important, but the effect on the user experience.The funny thing is that these “expert” nerds are actually less perceptive than the casual non-tech user, when the nerds never see the forest with their nose against the tree.Why does only one company look at the big picture?
