WORKSHOP TOPIC
It is generally accepted today, that knowledge about the tasks the user has
to fulfill with a computer system, plays an important role in the design
process. The more knowledge about the user tasks is available during design
time the more it can be exploited when defining the system's properties and
features, leading to a higher degree of user acceptance and user
satisfaction. Basically, this process starts with the analysis and modelling
of the user's tasks and uses the output of this modelling step in the
subsequent system design and evaluation phases.
Task modelling can essentially be done on two different levels, leading to
different models: Starting with the model of the current user tasks, a task
model assuming the target system to be in operation is developed. This
envisioned task model documents the task structure and the division of labour
between human user and system. Based on this second task model, the objects
as well as the dialogue structure of the interface are defined and captured
in an interface model. Hence, developers have to shift focus from the user
tasks and the objects involved in the tasks (task objects) to the interactions
and user interface objects as well as their implementation.
Currently, tool support mainly concentrates on user interface modelling of
standard applications and their implementation. Task modelling and its
transformation to dialogue, however, is hardly supported. Still, the various
studies concerning the transformations have resulted in several good ideas
and partial solutions. However, to make task based user interface design
more applicable for real projects tool support is necessary which takes into
account the various models and the different qualities of their transition.
We found significant support for this assumption during a workshop held at
CHI'98, entitled "From Task to Dialogue: Task-Based User Interface Design".
With 18 participants from industry and academia we discussed among others
matters of task modelling in everyday design practice and the impact of
formal methods and models in the field. There was one very clear result:
Everybody at the workshop wanted tools. It was universally recognised that
the user interface design process requires and supports multiple
representations at all design stages, and that each representation requires
and supports browsing, manipulation, and analysis tools. The opinion was
formed that the design task should be based on adequate tools, steming from
formal modelling or model-based approaches, which lead to a rather natural
outgrowth of tools to support various stages of design. One key to the
success of tools is that they "hide" the formalisms from the user or convey
them in a manner that is unobstrusive. The goal of this workshop is to
learn more about what formal methods and tool support are needed for
practical work in task-based user interface design.
To discuss this we want to bring together people from different viewpoints,
backgrounds, and domains:
* Researchers, working on model-based user interface design approaches,
theoretically oriented researchers as well as groups implementing
practically working design environments and
* Practitioners, creating user interface designs in their everyday work
practice, having to deal with "real" problems, "real" users and "real"
tasks.

WORKSHOP FORMAT
The workshop is supposed to be as interactive as possible. Therefore, after
a short round-table introductory statement from everybody including her or
his relation to the workshop topic, we will start group discussions as soon
as possible. Both groups, researchers and practioners, will have the chance
to discuss to some depth among themselves the needs, strategies, concepts,
techniques, and methods for task-based user interface design from their
respective viewpoints; additionally, in a second phase the groups will be
mixed, such that "research" and "practice" get a chance to discuss, to agree
and disagree, to influence and to learn from each other's opinions,
problems, and issues. Afterwards the whole group gathers again, each
subgroup reports its results in a short talk and a group discussion takes
place.

ORGANIZATIONAL ISSUES
Workshops provide an extended forum for small groups (15-20 people) to
exchange ideas on a specific topic of common interest. CHI'99 offers
workshops covering a wide range of HCI topics. The workshop announced here
will be held on Sunday, May 16, 1999 and Monday morning, May 17, 1999. This
workshop requires prospective participants to submit a position paper to the
organizers prior to CHI'99. Position statements are typically expected to be
two to four pages long and to outline participants' views on the workshop
theme and reasons for interest in the topic. Position statements should be
submitted directly to the organizers, at best by e-mail. The organizers can
also answer questions and provide additional information upon request.
Unless otherwise noted, position statements must be received by February
26, 1999. Submitters will be notified of their selection by March 26, 1999.
Accepted workshop participants will be charged a special registration fee of
$150 for this one and a half day workshop. If you are invited to attend, you
will receive a separate registration form, which you should fill out and
send with payment to the address provided on that. To share the important
issues and outcomes from the workshops with the rest of the CHI community,
organizers will have an opportunity and are encouraged to create posters and
show them during the conference.
