Workshop on Modelling Multiple and Collaborative Tasks.
IHM-HCI 2001, Lille, France, 10-14th September 2001.


Past approaches to analysing and modelling tasks have concentrated on individual tasks with clearly
defined start-  and end- points.  There has been much less focus on modelling individual or group
tasks that are undertaken in parallel or are interleaved.  These often occur in dynamically changing
environments, and with additional challenges, such as the occurrence of continuous activities
supported by sophisticated technology.

We need to understand how users work individually and within groups. The motivation for this
workshop has come from a number of research and practical considerations, such as:-
i)      the need to understand and model organisational, social, cognitive and communicative
and the knowledge involved in multiple  and collaborative tasks;
ii)     the need to assess the utility of current approaches to modelling multiple and collaborative
iii)    how to address the issue of gathering, analysing and modelling data related to multiple and
collaborative activities;
iv)     the appropriateness of different representational formats for describing multiple and
collaborative tasks, and subsequent contributions to design of interactive systems.

The workshop is timely and important for the design of future systems, to support multitasking and
collaboration.  We are currently being challenged by users in domains such as healthcare, where the
designed systems do not support the nature of the work being undertaken.  Often this work is
creative, with multitasking and teamwork.  The predominant  form of user interface is desktop direct
manipulation which inflicts a style of interaction and a manner of working that constrains users by
serializing and occasionally trivializing what would otherwise be complex, parallel tasks.


What factors dictate which tasks are undertaken in parallel?  Is this due to shared or common
knowledge, or constraining the use of cognitive or physical resources? What is the effect of
interruptions, and their relationship to errors? How do these change in different contexts and work

How information external to an individual or group is used and becomes part of the task context?
How groups undertake work by sharing and dividing responsibilities and pooling resources? How do
groups form goals and how do these relate to individual goals and plans for conducting tasks?


The workshop will provide a forum for designers, researchers and practitioners interested in
modelling individual and group tasks to present their own work and ideas.  Additionally, it is
expected that practitioners could consider the contribution of modelling approaches to identifying
requirements and designs for systems to support multitasking and collaborative tasks.


This one day workshop will include the following:


Introduction to the workshop and participants backgrounds
Short talks by participants, with discussions


Work on exemplar scenarios to investigate issues of concern;
what is to be modelled;
consideration of different modelling  (including any new) approaches;
issues to be addressed in designing systems to support multitasking and collaboration.

Report back/concluding session.


A likely output from the workshop is a report in Interactions, the bulletin of the British HCI
group.  Longer papers arising from this workshop could form the basis of an edited book or special
issue of a journal.


Extended abstracts (three A4 pages) in rtf format should be submitted to Peter Wild
([log in to unmask]) to arrive no later than 30/07/01.
