Hi Jens
As initiators to the HCI group that is now closed down and working with usability, we are still following the discussions in the HCI forum and find your PPT interesting. We have come up with 10 usability heuristics for TYPO3. They are drawn from different sources, Jacob Nielsen, Preece Rogers & sharp, Tognazzzi, Shneiderman, More & Fitz. See below. We intend to provide feedback to your slides with reference to the heuristics. We expect to finish our work in a weeks time, but (to everybody) please feel free to comment on the 10 usability heuristics.

1.1.Match between system and working processes in the real world
2.Consistency and standards
3.Recognition rather than recall
4.Relevant to user’s needs
5.Fitts's Law
6.Learnability
7.Use of Metaphors
8.Law of proximity
9.Law of similarity
10.Design dialog to yield closure
*1. Match between system and the real world*
The system should speak the users' language, with words, phrases and
concepts familiar to the user, rather than system-oriented terms. Follow
real-world conventions, making information appear in a natural and
logical order.
*2. Consistency and standards*
Users should not have to wonder whether different words, situations, or
actions mean the same thing. Follow platform conventions.
*3. Recognition rather than recall*
Make objects, actions, and options visible. The user should not have to
remember information from one part of the dialogue to another.
Instructions for use of the system should be visible or easily
retrievable whenever appropriate.
*4. Relevant to the user’s needs *
Make the system match the needs of different kinds of users in different
kinds of situations.
*5. Fitts's Law*
The time to acquire a target is a function of the distance to and size
of the target.
*6. Learnability*
Ideally, products would have no learning curve: users would walk up to
them for the very first time and achieve instant mastery. In practice,
all applications and services, no matter how simple, will display a
learning curve.
*7. Metaphors, Use of*
Choose metaphors well, metaphors that will enable users to instantly
grasp the finest details of the conceptual model.
*8. Law of Proximity*
The Gestalt law of proximity states that "objects or shapes that are
close to one another appear to form groups" (Moore, Fitz 1993). Even if
the shapes, sizes, and objects are radically different, they will appear
as a group if they are close together. How they are grouped is important
also. In designing instruction, it may be sometimes necessary to
eliminate or place elsewhere elements of the instruction that do not
lend themselves to the grouping taking place, to "create a stronger
sense of groups and differences" (Moore, Fitz 1993). In their example,
Moore and Fitz eliminated two sentences of information from instructions
on disassembling a light switch; this information did not pertain
directly to the tasks at hand but rather on background information that
may best be located elsewhere (or even assumed by the learner).
*9. Law of Similarity *
Gestalt theory states that objects that appear to be similar will be
grouped together in the learner’s mind (Moore, Fitz 1993). For visual
instruction, this can include font styles, size, and color, for example.
In the graphic below, the learner is likely to discern a shape in the
middle, though each individual object is the same color.
*10. Design dialog to yield closure*
Sequences of actions should be organized into groups with a beginning,
middle, and end. The informative feedback at the completion of a group
of actions gives the operators the satisfaction of accomplishment, a
sense of relief, the signal to drop contingency plans and options from
their minds, and an indication that the way is clear to prepare for the
next group of actions.
