Call for participation, Workshop on the Temporal Aspects of Tasks.

Workshop at HCI2003, University of Bath, U.K.

Monday 8th September 2003

All day workshop

Contributions in the form of 6 page position papers are invited for a workshop
at HCI2003 on the Temporal Aspects of Tasks.


In recent years HCI researchers have paid attention to temporal issues in our
interaction with computers. Much progress has been made in understanding
temporal issues at the user interface and their implications for measures of
usability such as learning, satisfaction etc. In contrast, less research has
been undertaken in understanding the temporal factors that shape tasks. The
tasks supported by an interactive system are an important determiner of
usability measures, yet they have been largely ignored in the research on
temporal issues. Yet, issues such as allocation, scheduling, sequencing,
deadlines and pace have already been shown to have some bearing on how tasks
are planned and executed and the overall effectiveness of interactive systems.


1) the need to understand how temporal factors shape the tasks that people
carry out;

2) the role of work / task study methods and representation formats in
eliciting and representing temporal issues;

3) the need to consider how temporal issues affect the planning of a task’s
execution (and whether as a result of this planning the tasks are executed in
serial, parallel, interleaved or collaborative forms;

4) the need to consider the effects of issues such as legal regulations or new
technologies on the temporal form of tasks;

5) the temporal properties of interactive systems and how such temporal
characteristics can influence design.

These preliminary considerations could lead to a wider concern with how
temporal aspects of tasks interact with other aspects of context such as
location, resources, and organisational structure.  Furthermore, we need to
consider how knowledge of temporal issues at the task level has implications
for the design of interactive systems and if and how it ties in with the lower
level research on temporal aspects of usability. Added to this when we consider
temporal issues at this higher level we may also end up addressing the boundary
between cognitive, social and technological views of time, and pushing towards
more interaction between cognitive and social models and theories about
computer use.

The workshop builds on the small amount of work that has attempted to look
higher level issues in temporal aspects of work; on existing general interest
in temporal issues in HCI at the user interface level; research into methods
for the study of tasks, and their representation and use. The workshop also
ties in with the demands raised by studying increasingly dynamic and complex
task domains.


The following are goals of the workshop:

1) to explore in more depth the temporal aspects of tasks;

2) to bring together people with different disciplinary backgrounds to discuss
and address the temporal aspects of tasks;

3) to bring together researchers and practitioners to better inform both
research and practice into the temporal aspects of tasks.


The workshop will provide a forum for those interested in the temporal aspects
of tasks to interact and discuss relevant issues and will be undertaken through
the following structure. The morning sessions of the workshop will be given
over to presentation and discussion of the position papers chosen by the
organising committee. The afternoon sessions will be given over to presentation
and discussion of one or more scenarios. These scenarios will be chosen to
reflect both a rich task and rich temporal structure. Workshop attendees will
be asked to discuss each of the two scenarios in the light of their own work /
theoretical position and / or experience in development contexts.


The workshop will provide a forum for researchers and practitioners interested
in temporal aspects of tasks to present their work and ideas. Researchers would
provide views of their own and their respective discipline’s contribution to
understanding of temporal aspects of tasks. It is expected that HCI / computing
practitioners could also provide 1) consider the contribution of modelling
approaches to identifying requirements and designs for systems to support
multitasking and collaborative tasks and 2) provide insights and scenarios
from "real world" experiences.

Participants will be selected on the basis of their interest in and familiarity
with the topic. Contributions will be circulated beforehand and posted on the
Workshop web site. We will also generate a discussion on scenarios .


The workshop is designed as a one-day mix of presentations and group
discussion, ending with a poster design session.  Please send your
contributions by 21st July 2003 to: [log in to unmask]  Acceptance
notifications will be sent on or before 31st July 2003.  Peter Wild is also the
