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. IOW this needs a control group so we can tell if the new design brings improvement or regression. Also, these tests measure usability, but not their overall impression. Did they like it? 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.

Re: Lucid changes to Firefox default search provider

I am pursuing this change because Canonical has negotiated a revenue sharing deal with Yahoo! and this revenue will help Canonical to provide developers and resources to continue the open development of Ubuntu and the Ubuntu Platform. This change will help provide these resources as well as continuing to respect our user's default search across Firefox. Since Google is the current default, will the switch to Yahoo only have an effect on new installs? -- Celeste Lyn Paul KDE Usability Project KDE e.V.

I must admit, on a large screen moving all the way from top to bottom of the scrollbar is a royal pain. I wouldn't mind having easier targets. Mac OS 8 and later fixes this with a much smaller change: it lets you put the arrow buttons next to each other at the bottom/right of the scrollbar, instead of at opposite ends. You can even drag from one button to the other while the mouse button is still down. KDE does a similar (but somewhat more confusing) thing by having two up/left buttons in a scrollbar, one at the the top/left and the other next to the down/right button. Hmm.. are you using a weird widget set?

In Mac OS X, a vertical scrollbar has one up button and one down button. The Appearance control panel lets you specify where the up button goes. (It's possible to have both buttons at both ends, but only using command-line settings or third-party utilities like TinkerTool.) 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
