Hi again,I am forwarding a second report sent by the same groups of students (~ 2 weeks ago). I am not really convinced, but it still deserves to be shared. :-)
Here is my answer to them: « So I've read your results and wanted to share my thoughts.First, you should make a little clear in your layout what is the problem and what is the proposed solution. It's not always clear. Using clear sub-headers may help. ;-)
For the linear vs perceptual issue, you consider figure 2 as a correct solution. But if not mistaken, this is the current dev UI, no? The buttons you circled are actually unrelated. The "Linear" button there is *not* a feedback to the 2 smaller buttons on the right (though it is interesting that you think so and show there is really a problem on this GUI). The toggle button with a "Linear" label is what control linear vs perceptual distribution on the X axis. The 2 smaller radio buttons control the Y axis. This is not the GUI we want because it is absolutely not clear and easily understandable.
As for the out-of-range issue, if I understand well, you propose to use percentage and simply show everything from the minimal to maximal value. This is interesting but we would need to make clear what is out-of-range and it doesn't really. As you say, showing values below the histogram could help on this, though. Yet this is not all that clear what is the exact GUI that you would suggest as a replacement. Reading your report, as a developer, I am not sure at all what I should change to make this whole GUI neater. :-/
In any case, that was a first time.If ever your university is interested by collaboration on user experience stuff, don't hesitate to tell them they can contact me. We may discuss more about what could be done to have a successful collaboration which could make a great university project while improving GIMP.

Hi all!
Some student from the "UI specialist group from University of Oulu"
(Finland), are contributing to the Finnish translation of the UI and
the manual, and also have done some usability testing.
Attached is the current state of the report that they sent us.
Note sure what is the organization on their side, but from what I
understood there is a group of bachelor and a group of master
students.
Note: they agreed for me to forward the report here (and said they's
subscribe to the mailing list).
I think it's cool to have usability testing from universities and we
are looking forward to have more with hopefully some fruitful
collaboration (this is a call to every university or other kind of
group of usability designers out there!).
As already told directly on IRC to them, the report is a bit short and
that would be interesting to get deeper insight and recommendations.
But that's a start and we are thankful to get approached with this.
:-)
Since the students still have 300 hours on the project, we are making
a small experiment by proposing them to work on a single feature which
is needed for 2.10 ("the linear, gamma and hdr issues of curves and
levels dialogs") and see what they would recommend. Pat David is going
to write a non-developer version to understand our problem so that we
can send it over. :-)
This was just for a short note on this topic.
