CALL FOR PARTICIPATION
CHI'90 Workshop
Modeling the User Interface
a comparison of approaches towards the "Mental Model"
Can we describe a user interface without engaging users? Can
we predict how difficult an interface will be to learn, to
understand, and to use? Can we prescribe how an interface
should be designed? In the HCI community there exist several
approaches to answer these questions by modeling different
aspects of the interface and of HCI.
A limited attendance, invitational workshop on Modeling the
User Interface is being organized for the CHI'90 Conference
in Seattle. The workshop will be arranged on April 1st and
2nd. This workshop aims at comparing, analyzing, and struc-
turing some different modeling approaches, for instance CLG,
GOMS, Cognitive Complexity Theory, TAG, and ETAG.
The following aspects will be discussed:
(1) aspect(s) of HCI covered
(2) general theoretical background
(3) descriptive power
(4) predictive power
(5) engineering applicability
Results expected consist of evaluations of the different
types of models for different purposes. Their merits and
drawbacks will be illuminated and an overview picture drawn
for when to use what model. Possible requirements for new
approaches will also be identified. The results will be pub-
lished in the SIGCHI bulletin.
Participants in the workshop should have experience with
working with modeling interfaces, either theoretically or
empirically. People who have already attempted comparisons
and analyses of different models are also invited to parti-
cipate.
Please send a description of yourself (experience, expertise
and interest) and a position statement (about 2 pages) to
the workshop organizers not later than February 6th, 1990
(prefarably by electronic mail).
The workshop organizers (Gerrit C. van der Veer, Free
University, Amsterdam, The Netherlands, and Yvonne Waern,
Stockholm University, Sweden) will invite participants on
the basis of the position statements (not later than Febru-
ary 20, 1990). The position papers and a final agenda will
be mailed to all participants, upon notification of accep-
tance.
A workshop fee of $50 will be collected from each participant to help
defray the costs of coffee breaks and A/V equipment.
