List of Workshops
There is rising interest
within the UbiComp community to research the roles of
interaction spaces and the elements they consist of,
and their effects on interaction, productivity, and satisfaction
in face-to-face collaboration. There are already several
approaches to support group work with adapted office
spaces and room elements, but none of them alone seems
to be an ultimate solution.
A key role for the success of these environments will
be in how they are realized. To build office environments
of the future it will not be sufficient to put traditional
PCs everywhere and expect them to foster interaction
and creativity among group workers. In contrast, collaborative
environments that adapt to the needs of group workers
would allow the computer as a device to disappear in
the architecture of office spaces, while its functionality
remains ubiquitously available.
Our motivation for this workshop is to bring together
researchers who are interested in face-to-face collaboration
and how new kinds of environments can support it. We
want to discuss previous results in this area and share
our experiences with the ultimate goal of finding emergent
research questions and future research directions.

W2: User centered Evaluations for Ubiquitous
Computing Systems: Best Known Methods
User-centered evaluations
must be performed on ubiquitous computing (ubicomp) systems
to determine if they are meeting their users' needs.
There has been a growing number of papers on ubicomp
systems in recent literature that have included user-centered
evaluations. In this workshop, we will leverage this
work to see if evaluation practices have evolved to
the point where we as a community can codify and publicize
a collection of "best known methods" and supporting
case studies.
Participants are asked to submit a position paper that
suggests an evaluation methodology and provides the
methodology's advantages and disadvantages. Details on
the format of the position paper can be found at
www.nist.gov/ubicomp02. Participants should be ready to
argue the validity of their approaches and compare and
contrast with other evaluative techniques. Prior to the
workshop, the organizers will group the proposed
methodologies into similar topics and select a participant
from each topic to present those methodologies. This
requires pre-workshop interaction between the participants
and organizers. Position papers should not exceed 4 pages.

W3: Supporting Spontaneous Interaction
in Ubiquitous Computing Settings
A spontaneous interaction
is one in which human and/or computational participants
coincide temporarily at a location and interoperate to
satisfy immediate needs. For example, two users who have
just met exchange documents between their PD's, or one
shows the other a document on a nearby screen in a place
that neither has visited before. In this workshop, we
focus on the temporary and serendipitous nature of these
interactions. We intend to explore models of spontaneous
interaction and understand how to facilitate and manage
it even though, by its nature, we cannot allow the set-up
costs typically tolerated in our systems today, and
any human involvement needs to be made very straightforward.
This full day workshop aims to provide a forum for
designers, developers and users of ubiquitous systems to
exchange experiences and contribute to the elucidation
of research challenges and directions for spontaneous
interaction in ubiquitous settings. We welcome participants
from a wide range of areas of expertise including
distributed systems, software engineering, and HCI.

W4: Emotions in the World
Facilitating and utilizing
emotions and affect is becoming a more common concern
in design practice, research, and education. Fields such
as computer science, HCI and interaction design are
discovering emotions as a possible vehicle for driving
the interfaces of handheld and ubiquitous devices. There
is, however, a real need to focus the discussion and
to gain a better insight into the nature of human emotions
and what their role might be in relation to technological
objects.
What do we want these technologies to do for us and how
will they fit into our lives?
The overall goal of the workshop is to enrich the current
debate on emotions and design. In particular our aim
is to allow participants to explore how human emotions
relate to objects and services in the surrounding worlds
and how devices and services may be designed to express
and support individual and collective emotion states.
We are looking for submissions from designers, researchers,
and practitioners in the fields of computer science,
human sciences, interaction design, industrial design
and engineering. Please see http://emotions.ifonly.org

W5: UbiCog '02: First International Workshop
on Ubiquitous Computing for Cognitive Aids
To date computer systems
designed to help people suffering from cognitive
disabilities due to aging, disease, or accidents have been
rare and of limited scope. Recently, however, researchers
in ubiquitous computing and artificial intelligence have
come together to envision systems that can act as pro-active
partners in increasing the independence and security
of people who have problems of memory, planning, and
carrying out tasks of everyday life.
Intelligent ubicomp systems for caretaking can take many
physical forms, such as sensor-filled intelligent homes
or hospitals, wireless PDA's, wearable computers, or
combinations of these. Goals of such systems include
``aging in place'' (allowing the elderly to live securely
in their own homes); prolonging or increasing the independence
of patients in traveling from place to place; performing
household tasks such as cooking or personal grooming;
monitoring and reminding patients to take medications;
and helping patients remain connected to the social fabric
of their extended family and community.
This workshop will bring together academic and industrial
researchers performing cutting-edge work in the intersection
of ubicomp, artificial intelligence, and/or patient care,
as well as representatives of some funding agencies.

W6: Workshop on Socially-informed Design
of Privacy-enhancing Solutions in Ubiquitous Computing
Privacy-enhancing solutions, both technical and social,
are needed to drive development of ubiquitous computing
in a socially acceptable direction. The goal of this
workshop is to develop an understanding of how social
studies can inform the design and evaluation of privacy-enhancing
solutions in ubicomp.
When engaging a ubicomp system to interact with another
agent, whether user or system, users have to concern
themselves with the trustworthiness of the other agent,
the environment they are in, and the controller of the
environment. Many actors are involved, each with different
incentives to gather and use information about the user.
It is unrealistic to assume clean separations between
technical, behavioral, legal and social factors influencing
privacy.
This workshop aims to provide a forum for ubicomp system
developers, security researchers, social scientists
(including legal experts) and consumer privacy advocates
to collaboratively explore the future of socially-informed
privacy-enhancing solutions (technical approaches and
complementary laws and policies) in ubiquitous computing.
Questions from other disciplines other than computer
science (e.g., economics, sociology, law, public policy)
will contribute significantly to the workshop.

W7: Security in Ubiquitous Computing
The questions that Ubiquitous computing may introduce
to security can be associated with the central themes
or buzz words of ubiquitous computing. For example, the
concept of ubiquity of resources and services certainly
raises questions for confidentiality, authorization and
access control, while augmented reality leads us to
wonder about the resultant augmentation of security threats.
Many of the issues regarding privacy and context awareness
are focused on location, however, context information
goes beyond location such that a breech of privacy may
also be in jepoardy of revealing more than location.
The concepts of the Invisible COmputer and Smart Items
indicate a need to re-think technologies and notions
surrounding trust, ownership, accountability and non-repudiation.
Furthermore, with increased Mobility and Portability
there is increased distribution and diversity of operating
platforms and inter-networks. Therefore, what will an
infrastructure supporting end-to-end security resemble
in these environments?
As Ubiquitous Computing seeks to move computers into
the background while using them to enhance human endeavors,
we have to thouroughly evaluate and determine the likelihood
that society will indeed accept and trust this successor
to interactive computing. Furthermore, the balance between
the usability that ubiquitous computing seeks to facilitate
and the complexity of security needs to be resolved.
This workshop therefore contributes to this field by
bringing together professionals prepared to address and
brainstorm over these important issues for security in
ubiquitous computing.

W8: Concepts and Models
for Ubiquitous Computing
Ubicomp has produced
many innovative and exciting systems and applications
alongside broad visionary viewpoints. However, more generic
design focused concepts and models will become essential
as ubicomp moves from an exploratory research area to
being the normal pattern of human–computer interaction.
This workshop is for those interested in developing the
generic understanding of interaction needed to make sense
of ubiquitous environments. This will include those
developing new interactive approaches and metaphors,
those reflecting on experience of development and those
constructing supporting software architectures.
We wish to bring together researchers interested in the
fundamental principles of ubiquitous interaction. This
will include system-orientated architectural and device
models; user orientated cognitive models; new paradigms
and metaphors; and discussions of the nature of user’s
understanding. The breadth of scope is based on experience
within the user-interface community where there is a
considerable overlap between conceptual understanding
and architectural models of interaction.
The experimental systems designed today are unlikely
to be those used in 5–10 years time or beyond, but the
lessons they teach us will be of enduring value. This
workshop will be the first of an ongoing series of international
workshops aimed at making these generic lessons explicit.

W9: Design and Evaluation of Notification
Interfaces for Ubiquitous Computing
Advances in computing and networking technology during
recent years have pervaded many environments in many
forms. The computer has evolved from a solitary, desk-bound
box that demanded the user’s entire attention to a collection
of smaller, ubiquitous information and communication
appliances connected to a host of other such appliances
and users, approaching Weiser’s vision of the pervasive
and invisible computer. At the same time, users want
these devices to be both highly informative and ecologically
unobtrusive, keeping the user aware what is going on
in various ways without unduly disrupting the current
social or environmental context.
Notification systems attempt to
deliver current, important information to the computer
user in an efficient and effective manner. Notifications
are involved in alerts, presence and awareness updates,
location and context awareness, communication initiation,
instant messaging, and information-on-demand (information
that is “pushed” to the device according to a standing
request from the user). All notification systems require
that the user attend to them to at least some degree
if they are to succeed. It is becoming apparent that
the design of appropriate notifications is an important
aspect of ubiquitous computing applications. However,
to date there has been little formal design or evaluation
of notification interfaces in this area. In this workshop
we would like to focus on the nature of notifications
such as alerts, messaging and presence information on
portable computer, PDA and cell phone users, and how
to optimize their design.
