I think Preferences are a good tool for reconciliation of our UI
differences. However, another good tool is if we can establish a
constructive dialogue about UI. Such a dialogue could perhaps
occasionally spare us a new preference in favor of a slightly more
cohesive result, because it was a solution that was good enough for
the overwhelming majority. Let's talk about it! Of course
preferences are great because they allow our users to heavily
customize the system..
I hope, my having gone through Maui and forced myself through dozens
of painstaking design and usability choices, at least illustrates my
own _interest_ in this subject. I'm interested, in talking about
these ideas with those interested in making Squeak look drop-dead
gorgeous not just on the surface, but in the details too.
Understanding each others' core-UI principles I think would be very
helpful in establishing a constructive dialog. Here are mine:
1) That, at least the a software dev-environment (which is about what
we're talking about), that this software, Squeak, expects users to
have Basic Computer-Literacy before attempting to use Squeak.
"Basic Computer Literacy" is defined as:
- Use of the keyboard, including the Enter or Return key, arrow
- Use of the mouse as a pointing device.
- Use of the (red/left/primary) mouse button as a means to
"select" or "activate".
- Use of the (yellow/right/alternate) mouse button, and
understanding that is how to ask an object for options or information.
2) A user with Basic Computer Literacy, will be able to, at least,
_discover_ how to operate a system with merely those skills. If the
system requires further skills, it should be discoverable via help or
guidance-elements accessed only with BCL. Typically, users learn
about UI-elements not already obvious to them by yellow-clicking for
interrogation and discovery.
3) Humans direct, software responds. Software should take care not
to interrupt human. Software should no't ask "are you sure?",
instead, provide undo.
4) Ensuring not to break rule 2, give the user the most powerful
gestures possible to efficiently operate the software. This typically
- minimize the demands of the users fine motor-skill (i.e.,
- employ high-traction strategies, such as the power of pointing
- good keyboard support is almost always, really necessary.
That's it, those are my UI principles. If software requires user to
be "frantic" to go fast, then it does not provide enough
The principles I heard from rado are:
- favors practicality over aesthetic
- that the machine should make it easy on him, not force his eyes to
"search for the corner" to see the status (and not forgetting, there
may be several dirty windows with their corner exposed)
I understand these. The principles from Igor are:
1. friendly for newcomers
2. convenient for citizens.
however, I am not sure what he meant by "friendly" and "convenient".
Igor, I am very interested in your ideas in a constructive dialogue..
