AIMS 2004: Artificial Intelligence in Mobile Systems

Today's information technology
is rapidly moving small computerised consumer devices and hi-tech personal appliances
from the desks of research labs onto sales shelves and into our daily life.
These include low performance PDAs, embedded computers in cameras, cars, or
mobile phones, as well as high performance wearable computers and tablet PCs.
Many of these devices are becoming essential tools that we rely on increasingly
both in private and in professional settings. In addition, a growing number
of locations are being outfitted with ubiquitous devices and networking access.
This combination promises to enable new approaches to solve daily tasks and
to open up new possibilities.
However, in order to use
these systems new interaction metaphors and methods of control are required.
Well-known interaction devices, such as mouse and keyboard are oftentimes unfeasible
or even unavailable, thus rendering user interfaces that rely on them inappropriate.
Other resources such as power or networking bandwidth may also be limited or
unreliable depending on time and location. Moreover, the physical environment
and context can change rapidly throughout the interaction with mobile systems
and must be taken into account appropriately. Spatial and temporal relationships
between devices and users are continuously changing as well and may be a key
factor to be considered when interacting with a ubiquitous infrastructure.
In addition, we can expect
a shift from single users towards groups, from single applications to multiple
concurrent services, and from strictly personal to (semi-)public artefacts that
can be configured dynamically. The resulting complexity needs to be addressed
on all levels, from interface design to power issues. Within the field of Artificial
Intelligence, several of these problems have been investigated for many years
(such as how to make user interfaces more adaptive or how to deal with limited
technical or cognitive resources). Therefore, AI methods are promising tools
for building mobile and ubiquitous systems that are aware of the location and
situation of their users, and that can unobtrusively adapt to these factors.
The AIMS 2004 workshop intends
to bring together researchers working in various areas of (applied) AI as well
as in mobile and ubiquitous computing systems. The workshop aims to explore
recent research and findings in AI, the development of mobile systems and their
seamless integration in ubiquitous computing environments. The main objective
of the workshop is a lively discussion and exchange of ideas. The scope of interest
includes but is not limited to the following items (in no particular order):
- location and context
awareness as well as knowledge-based acquisition of contextual information
- spatio-temporal issues
and methods in mobile and ubiquitous applications
- interaction metaphors
and interaction devices for mobile and ubiquitous systems
- intelligent user interfaces
for mobile and ubiquitous systems
- multi-modal interfaces
for mobile and ubiquitous systems
- user interfaces that
adapt to the current situation as well as to resource availability
- seamless integration
of mobile systems in ubiquitous computing environments
- plan-based approaches
for interaction and adaptation
- user modelling and cognitive
- trade-offs between reasoning
capabilities, resource consumption and real-time constraints

SCOPE & AIMS
The goal of this workshop
is to bring together top researchers from academia and industry to facilitate
the exchange of ideas and the fostering of collaborations on location-aware
applications. The workshop will discuss new location-aware applications, debate
the challenges and capabilities offered by new technologies, and reflect on
the drivers and barriers to deployment of location-aware applications. Topics
of interest include:
- The end-user value that
location information adds to different classes of applications
- The reasons some applications
are sufficiently compelling that users are willing to disclose their location
- Which devices and platforms
will prove the most "location-aware"
- The dependence of location-based
applications on the social actions that it may engender or replace
- Applications that require
location-infrastructure that allows users to mask, blur or even lie about
- Ways of conducting feasible,
yet meaningful, evaluations of location-based applications
- Techniques for quantifying
the value of location information in particular applications
- The role that centralised-server
applications (e.g. web-based applications) will play in the location-aware
Selection of workshop participants
and presentations will be based on refereed submissions. Authors are invited
to submit a one-page position statement in the ACM SIGCHI conference publications
format. Position statements should have only one author, and should include
a brief biography in addition to a discussion of a viewpoint or experience with
location-aware computing applications. Please email submissions in PDF format
no later than 26 July 2004.
The workshop will be highly
interactive, and include six short talks with panel-based discussion periods,
as well as "whirlwind" sessions in which every participant will be
asked to present 2 slides concerning their work.
A workshop proceedings will
be distributed to participants, and will also be available online in PDF format.

This workshop will explore
how emerging sensor technologies can be used to create new playful ubiquitous
applications. It will focus in particular on how the inherent uncertainties
of sensing technologies can be deliberately exploited as part of games and entertainment,
rather than being seen as a problem to be solved or swept away under the
The workshop will be structured
around a series of subgroup discussions each of which will take one sensing
technology, one playing application and one design approach, and will produce
a design pitch to be presented back to the workshop as a whole.
Ubiquitous computing employs
a wide variety of sensing technologies to capture rich and dynamic information
about people and environments so as support reactive, embedded and contextually
aware applications. There is a bewildering array of sensing technologies available
including global positioning systems, video-tracking, load-sensing, ultrasonic
tracking, embedded accelerometers, light sensors, sound sensors, electrostatic
field sensors, pressure sensors and many others.
A common issue in using
these technologies is their inherent unpredictability. Compared to familiar
input devices such as keyboards, mice and joysticks, ubiquitous sensing technologies
often deliver uncertain results their range may be unclear, their measurements
may be noisy, they may be subject to interference, or it may be difficult to
reliably derive descriptions of high-level human activities from low-level sensor
data that they provide.
These uncertainties raise
new challenges for application designers, especially with regard to user interface
design. However, we suggest that they also present new design opportunities,
especially for artistic and playful applications such as art installations,
performances and games, which are becoming increasingly visible applications
of ubiquitous computing. Such applications might deliberately exploit uncertainty,
ambiguity and the seams in technologies to create engaging and provocative experiences.
This workshop will bring
together researchers who are developing sensing technologies with the designers
of playful applications artists, product designers and games designers
to exchange perspectives and to engage in a series of focused design
sessions based upon specific combinations of technologies and applications.
The workshop will involve
several focused discussions in subgroups, each of which will take:
- an emerging sensing
- a playful application
- a design approach or
and will work up an outline
design pitch for a specific playful application that makes an innovative
and engaging use of the sensing technology and in particular the copes
with or even better, exploits the uncertainties in the sensing technology.
The workshop organizers
will act as facilitators, guiding the subgroups and ensuring that they remain
on focus. Each group will pitch its ideas back to the other groups as part of
a final discussion. The overall workshop will be structured as follows:
- one and a half hours
of introduction and initial presentations of short papers on the technologies,
application areas and design frameworks;
- four hours focused design
sessions in subgroups (including lunch);
- one and a half hours
of final presentation of pitches and discussion.
After the workshop the organisers
will produce an archive website for dissemination of the original inputs and
a summary of the final outputs.
Submission deadline for
two page position papers: July 30th
deadline: August 9th 2004

2nd International Workshop on Ubiquitous Systems for
Supporting Social Interaction
Communication in Public Spaces

Public spaces, such as conferences,
museums, cafes, and workplaces present new opportunities for ubiquitous computing
technologies. Such spaces represent important venues for social interaction
and the informal exchange of knowledge, providing a place to find others who
share common or complementary interests. As discovered in last year's workshop,
we have only begun to understand the challenges and questions associated with
situating ubicomp technologies within such spaces.
For example, how do people
find others who share their interests and develop their social networks? How
can technologies provide richer ways for people to communicate and engage with
others? How can the serendipitous exchanges and interactions that often occur
within public spaces be supported? How and where does the interaction between
people happen? In view of these questions, the proposed workshop seeks to bring
together like-minded researchers and practitioners to better understand the
design, development and evaluation of ubiquitous systems for supporting social
activities and social interaction in public spaces.
The main subject of the
proposed workshop is the development and use of ubiquitous systems to support
social interaction in public spaces and at public events, such as museums, conferences,
trade shows, etc. Topics relevant to this subject include:
- Applications: existing
commercial and experimental applications, e.g., ubiquitous systems in museums,
at public gatherings, etc.
- Pattern Recognition:
how to learn socially relevant features from raw sensor data and build computational
models of the dynamics.
- User interface: how
to provide a simple and intuitive user interface for novice users to a complex
- Presentation: how various
types of information acquired by the ubiquitous system can be effectively
presented to the end users.
- Scalability: how to
accommodate a large number of simultaneous users at a potentially unlimited
number of locations.
- Deployment: how to package
the system so that it can be easily deployable in an environment that is not
prepared for such type of applications.
- Reliability: how to
build robust and reliable systems that can guarantee at least some minimal
number of services.
- Privacy: if the system
"knows" everything about everybody currently present in the tracked
ubiquitous environment, what are the privacy concerns and how best to address
- Security: what happens
if the system is defeated and the intruders gain access to all the accumulated
knowledge. How to prevent this from happening.
- Social aspects: how
the technology can be used to help forming social networks and how it can
be used to study them.
- Evaluation: how the
services provided by a system can be evaluated, what are the evaluation criteria,
what does it mean to build a practical and useful system.
Participants are asked to
submit position papers, no more than 6 pages in length, consisting of the author's
vision and/or experience of the design and usage of ubiquitous systems for public
spaces. Proposals for demonstrations and posters are welcome.
Position papers should be
submitted electronically to email@example.com
on or before July 26th as a PDF or MS Word file formatted according to the ACM
SIG Proceedings Format (http://www.acm.org/sigs/pubs/proceed/).
Papers will be selected based on their originality, merit and topical relevance.
A review panel consisting of the workshop organizers and external reviewers
will be assembled to evaluate the submissions. Notification of acceptance will
be sent out by August 2nd, 2004. Accepted papers will be included in the workshop's

Computing for Pervasive Healthcare
Tim Adlam (Royal United Hospital, Bath, UK)
Wactlar (Carnegie Mellon University, Pittsburgh, USA)
Korhonen (VTT Information Technology, Finland)
The UbiHealth 2004 workshop
is focused on bringing ubiquitous computing technology to bear on challenges
in health and social care. It includes technology to support people at home
or in care facilities, and to broadly improve the delivery of health and social
care. The aim of pervasive care is to deliver continuous, appropriate and effective
aids so that the recipient is provided with an improved quality of life. This
spans assisting people with cognitive, perceptual and mobility impairments independent
of age. If these aids are used by the care provider, the goal is further to
deliver that care more efficiently, less stressfully, and always with compassion.
The aim of the workshop is to build a global community of researchers who are
working in this combined context. This year our emphasis will be to examine
real world applications of ubiquitous computing to health and social care, considering
how it can be introduced, evaluated and delivered for the benefit patients and
caregivers within government regulatory frameworks. The workshop will explore
these issues through the presentation of papers describing the participant's
experiences with early deployment, their visions for future research and application
opportunities, and a panel question and answer session. Experts will be invited
to initiate the panel discussion with a talk on ethical issues.

UbiComp in the Urban Frontier
Eric Paulos (Intel Research, Seattle, USA)
Ken Anderson (Intel Research,
Townsend (New York University, USA)
UbiComp in the Urban Frontier
is a one day workshop to be held at the 6th Annual Ubiquitous Computing Conference
in Nottingham, England. This workshop will be focused on understand how the
rapidly emerging fabric of mobile and wireless computing will influence, disrupt,
expand, and be integrated into the social patterns existent within our public
There is little doubt that
laptops, PDAs, and mobile phones have enabled computing to become a truly mobile
experience. With these new computing devices, we emerge from our office, work,
and school into the urban fabric of our cities and towns. We often view these
urban areas as in-between spaces obstacles to traverse from one place to another.
However, not only do we spend a significant amount of time in such urban landscapes,
but these spaces contribute to our own formulation of identity, community, and
self. Much of the richness of life transpires within our own urban settings.
Similarly, there is a growing body of work within the field of social computing,
particularly those involving social networking such as Tribe, Friendster, and
Live Journal. At the intersection of mobile and social computing, we seek to
provoke discussion aimed at understanding this emerging space of computing within
and across our public urban frontiers.
While toting a laptop around
a city may seem a like an example of such city computing, the urban frontiers
workshop will be more deeply concerned with addressing several sub-themes, including
(but not limited to):
- Place What is the meaning
of various public places? What cues do we use to interpret place and how will
Urban Computing re-inform and alter our perception of various places?
- Community Who are the
people we share our city with? How do they influence our urban landscape?
Where do we belong in this social space and how do new technologies enable
and disrupt feelings of community and belonging?
- Infrastructure How will
buildings, subways, sidewalks, parking meters, and other conventional, physical
artifacts on the urban landscape be used and re-appropriated by emerging technology
- Traversal What is a
path or route through a city using these new urban tools? How will navigation
and movement, either throughout an entire city or within a small urban space,
be influenced by the introduction of Urban Computing technology?
The timing of the Urban
Frontiers workshop is aimed at capturing a unique, synergistic moment expanding
urban populations, rapid adoption of Bluetooth mobile devices, and widespread
influence of wireless technologies across our urban landscapes. The United Nations
has recently reported that 48 percent of the world's population currently live
in urban areas and that this number is expected to exceed the 50 percent mark
by 2007, thus marking the first time in history that the world will have more
urban residents than rural residents. Current studies project Bluetooth-enabled
devices to reach 1.4 billion units in 2005 alone. Nearly 400 million new mobile
phones are scheduled to be sold worldwide this year alone. WiFi hardware is
being deployed at the astonishing rate of one every 4 seconds globally.
We are gathering for an
event to expose, deconstruct, and understand the challenges of this newly emerging
moment in urban history and its dramatic influence on technology usage and adoption.
We invite position papers on topics related to these themes.
Selection of workshop participants
and presentations will be based on refereed submissions. Authors are invited
to submit a two-page position statement in the ACM SIGCHI conference publications
format. Position statements are encouraged to be provocative and will be used
during the workshop to guide and disrupt our views of the urban frontiers. They
may include personal experiences, performances, studies, or individual urban
projects. Position statements should have only one author, and should include
a brief biography. Further submission details will be posted on the workshop
website in the coming week.
Please email submissions
in PDF format to firstname.lastname@example.org

- Sep 7, 2004: Workshop at Ubicomp 2004
Recent years have seen a
dramatic improvement in display technology.Although not as pronounced as the
advances in computer processing and memory capabilities, it has nevertheless
created a situation where displays - ranging in form factor from very small
to very large - are available at relative low cost and are being used for everything
from digital picture frames to building-sized billboards. The large scale deployment
and use of displays in public (airports, train stations, etc.) and semi-public
spaces (home, hospital, etc.) raises important questions in the areas of human-computer
interaction, computer-mediated communication, distributed systems, and networking.
This workshop intends to
bring together researchers and practitioners from a wide variety of disciplines
with the goal to identify and discuss issues related to the design, implementation,
use and evaluation of biquitous display environments. The immediate objective
is to foster a multifaceted investigation; the ultimate goal is to define a
research agenda for the area as a whole and to stimulate new research initiatives.
A particular focus of this workshop is to investigate the implications of new
display technologies for system design and interaction.
The scope of interest includes
but is not limited to:
- Novel display technologies
- Interaction techniques
for ubiquitous display environments
- Applications and scenarios
- Toolkits and authoring
- General methods and
- Multi-display environments
The workshop is planned
to bring together 10-15 people with various backgrounds and interests. We welcome
participants from all disciplines that are related to ubiquitous display environments,
including but not limited to engineering, human-computer interaction, industrial
design, and economics. We are particularly keen on attracting people from industry
as well as academic.
will be requested to submit possible topics for discussion. Communication between
participants will be facilitated prior to the workshop, via e-mail, to begin
discussion of the workshop topics. To maximize information and idea exchange
and foster collaboration, we plan to spend most of the time on discussions rather
than presentations. The primary activities at the workshop will take place in
small working groups made up of 3-4 people.
The participants will be
selected on the basis of a submitted paper (up to 6 pages in Springer LNCS format)
describing their interest and experience in the field, or ongoing research.
Submissions will be reviewed by the workshop organizers and outside experts.

presents an overview of feasible scenarios where mobile and web interfaces intersect
in the space of communication between users, as well as illustrates how well
designed integrated interfaces system between technologies may compliment mobile
lifestyles. Although the technology is converging to make ubiquitous communication
possible, HCI innovation in this area should arise in order to make an impact
in its popularity and wide spread usage.
innovations in how we communicate have spurred a trend toward scenarios where
ubiquitous communication scenarios are more common. With the advent of wireless
communication network standards (such as 3G, 4G and blue tooth, WiFi) and the
ever increasing adaptation toward a nomadic life style; communication between
individuals, groups and communities now occur over networks and devices that
are most suitable for an individual's location, time, and environment. People
choose methods of communication with capabilities that best meet a specific
circumstances. For example, wireless handsets have mobile and geographic qualities,
such as context sensitivity, which make it ideal for those travelling and seeking
local information; where as a person who is stationery at a workstation may
find emailing or instant messaging on a key board more convenient.
As a result of so many choices to communicate, an eclectic system of devices
(PC's, laptops, i-TV, mobile phones, PDA's, tablets, etc) and applications (such
as, email, chat, instant messaging, SMS, MMS, etc) has emerged. This technological
convergence of communication devices poses HCI issues where web and mobile interfaces
the popularity of the web based applications for communicating and the wide
spread usage of mobile phones grew independently; however new innovations in
technology, have converged functionality. Interface design must also converge
and begin to address how the continuity of the user experience between these
two mediums will fuse and avoid incompatibility. For instance, previously, if
users of these two devices wanted to share photos with another, they may have
had to take a photo with a digital camera, then had to wait till they were near
a computer with internet connection to download pictures, then post them on
the web. With the convergence of these technologies, however, it is possible
for users to take, edit, send, and post photos on the internet, (and visa versa)
or broadcast it on i-TV, all in one continuous processes on a single device.
The challenge is to design interfaces that take into account a continuous user
experience across mediums.
design patterns, human factor studies, behavioral theories and evaluation techniques
in ubiquitous communication scenarios must arise in order for these technologies
to enjoy wide spread popularity and usage.Topics are listed as blow:
historic overview of wireless devices and internet applications for communicating
scenarios of communication technology convergence: an overview wireless devices
and internet based applications
scenarios: the nomadic culture and its development in the different everyday

activities (tests and experience sessions) and group discussion. A half-day
workshop, while less desirable, would also be possible, although it would imply
a reduction of the content.
Due to the interactive format of some sections of the workshop, a group no bigger
than 30 participants will be suitable to positive share knowledge and experiences.
However, if the interest in this topic significantly increases and request to
participate warrant, then
it would be possible to consider reformatting the workshop to accommodate larger

situations of use, information and communication needs of different target groups
of the same given mobile application scenario. The results will be discussed
and compared in order to gather an understanding of the need of information

Workshop on Advanced Context Modelling, Reasoning and
Jadwiga Indulska (University of Queensland, Australia)

There is growing interest
in the development of context-aware ubiquitous systems which can support seamless
computing for mobile users in integrated, heterogeneous environments built from
a variety of network technologies, sensors and computing devices. In addition,
there is growing interest in context-aware applications that intelligently support
user tasks by acting autonomously on behalf of users in these integrated, ubiquitous
environments. However, there is also increasing recognition of challenges associated
with context-awareness, including barriers associated with scalability and usability
and novel software engineering problems. This workshop focuses on context models
that provide abstractions to foster context reuse and ease of programming, and
support development of scalable, robust, reliable and usable context-aware applications.
The workshop also responds to the growing popularity of ontology principles
and methods in ubiquitous computing systems, and examines the role that these
can play in context modelling and reasoning about context.
This workshop offers the
opportunity to bring together researchers involved in the development of context
models and context-aware applications for ubiquitous computing environments.
It aims at exploring the most recent research results and ongoing work in the
areas of context modelling, reasoning about context, and management of context
information. Special emphasis will be placed on presenting state of the art
and emerging research as well as experience reports from the following research
- formal or disciplined
approaches to modelling context
- semantics of context
models and expressiveness of different context modelling approaches
- ontology-based approaches
to context modelling and reasoning
- comparison of different
approaches to context modelling and reasoning, including ontology-based and
- advanced issues in context
modelling and reasoning, including:
- issues of imperfect context information, including ambiguity and incompleteness
- issues related to temporal and spatial information
- distribution and structuring
of context information
- scalability, integration
and reuse of context models
- interoperability of context
- evolution of context
models and versioning issues
- experiences with using
context models to build ubiquitous computing applications
The workshop will be organized
into panels and breakout sessions. The results of the breakout sessions will
be presented in a plenary session at the conclusion of the workshop.
This workshop will last
for 1 full day and will be limited to 20 participants to enable productive discussions.
Participants will be invited on the basis of position papers, which will be
selected based on their originality and contribution to the workshop topics.
Position papers should address at least one of the workshop topics and be in
the form of a technical paper, experience report, or work-in-progress report.
The papers will be refereed by the workshop Program Committee. We are seeking
cooperation from an international journal to publish selected extended workshop
Each position paper should
be no more than 6 pages in length and should be in ACM SIGCHI format (http://www.acm.org/sigs/sigchi/chipubform/).
