Please post "before" and "after" screenshots, demonstrating the above conclusion.
How are you measuring touch reliability of the buttons without a prototype touchscreen device? Are you just placing your finger on a computer screen?
You create the screenshots. You test them with your own software. You post the results if you want. See how things work out for you.
I cannot post the touchscreen software because I don't own it: it's proprietary. It's in-house stuff developed from years of UI design and other places. I didn't develop it myself: I only had a small part in its development. We're not the only ones who use this stuff... by the way. Lots of people in the industry have their own iterations of it.
Second, I don't own the results of the data, and I want to keep eating... but if you PM me, I could give you some more indication of what the data says.
The way the software works is you map out hit areas in a pixel perfect array. The software knows where the hit areas "start" and "stop". When you touch a button, the software will register whether your finger a) stays within a target
y or b) touches more than 1 target simultaneously. The software can also use a set of constants like average finger size, etc. to run simulations without the need to do any empirical interactions. It'll calculate cluster coefficients for you. But the model is harder than actually scaling down a screen and testing because there are several variables that need to be accounted for.

Uh-huh.

Do you really have to wonder why? Because the whole "usability testing" thing is something he just made up, once he was pinned down to present some evidence in support of his outrageous claims.
And he is still making things up, as he goes along. It's fun to watch.
Sure, it certainly is. I'm sorry but I don't remember every little thing between all of the Apps. I really didn't remember what the problem was with Safari until I came in this morning. I didn't even remember what buttons were in the top left except back and forward. I new there was two other symbols but they always confuse me.
And if you asked me right now what the problems were with Pages, I wouldn't be able to tell you because I don't remember. I don't even know what's in the top toolbar offhand.
So no, I'm not making it up as I go along. I'm old and tired.

If anyone wants a scaled down screenshot of Safari, PM me, and shut your mouth where you're getting any of this information.
