I actually think Unity is great and every single Ubuntu novice I have shown it to picks it up in no time.
I don't know about the metrics you propose, I think user experience takes in more variables than those. I'm a power user by the way and usually make use of 9 view ports (compiz desktops) . I think Unity comes into its own when you learn the keyboard shortcuts. But newbies who stick to the mouse find it very easy.
Canonical do a lot of user testing but it's obvious that they're trying to create a user interface that can work for everyone, everywhere, on all devices. That's a mammoth ask and I reckon they're doing something that not even Apple can do elegantly.
OK. If I am a software developer then Elvis still lives. So maybe this is all reinventing the wheel. I don't know.
Anyway. I find Unity in ubuntu very counter-intuitive. It feels weird.
Yet it is meant to be the latest thing/fad/trend to make me happy. No evidence. No measurements. No tests. I am just meant to be a "happy" Unity user. So, what about this:
1. the distance the mouse travels across the screen to use a GUI
2. the number of mouseclicks.
3. the clock time taken to do task x.
1 + 2 + 3 = user figure for a GUI. The lower the score the better.
All you guys here who make software. Do you do any measurements like this to arrive at the usability of software such as a GUI or anything else? Or is it just Macbeth Witches style chuck in eyes of newt, frog legs, pigs' blood and basil into the cauldron and hope for the best?
