* W9: Design and Evaluation of Notification Interfaces for Ubiquitous Computing

W1: Collaboration with Interactive Walls and Tables
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 for submission details

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.
