What would be telling is if the people who didn't figure out the task the first time remembered how to complete it the next time. That shows that the task is learnable, which is acceptable if the curve matches the difficulty of the functionality. Unfortunately very rarely do you use the same users for multiple tests (in fact it is usually discouraged unless you are doing longitudinal studies) except in longitudinal studies. > > I'm curious whether these stats are higher/lower/same-as with Classic > Desktop.

Find it frustrating/confusing? Do people in the UK use the System Usability Scale, NASA TLX, or Modified-Cooper Harper? Theyre assessment surveys that measure satisfaction and cognitive load, but I've only seen human factors engineers use them. > > Bryce > > -- > ubuntu-desktop mailing list > ubuntu-desktop@lists.ubuntu.com > https://lists.ubuntu.com/mailman/listinfo/ubuntu-desktop > -- Celeste Lyn Paul KDE Usability Project KDE e.V.

I like the sound of "Application Catalog". Library seems to play too much on metaphor, but Catalog has a similar feeling/meaning without invoking too much real world meaning. -- Celeste Lyn Paul KDE Usability Project usability.kde.org -- ubuntu-desktop mailing list ubuntu-desktop@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-desktop

Aah, I see. Strange, all of the screenshots I googled had three arrow buttons. > In KDE, as shown in your screenshot, a vertical scrollbar has two up > buttons and one down button. It's not obvious why going up is twice as > important as going down, and having multiple buttons for the same task > causes dither. Hum.. I've never noticed anyone have problems with it during testing before (~ 30 participants using KDE in various ways) and I don't remember anyone from OpenUsability mentioning anything. I think the second up arrow is a simple single-learning event, if you want to try the up arrow, it is obvious what it does and so the user can choose to use that method or not. Scrolling is not inhibited by it. *shrugs* > > Cheers > -- > Matthew Paul Thomas > http://mpt.net.nz/ -- Celeste Lyn Paul KDE Usability Project usability.kde.org -- ubuntu-desktop mailing list ubuntu-desktop@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-desktop

Hmm.. are you using a weird widget set?
