Many aspects of Mark Weiser's original vision of ubiquitous computing are rapidly becoming reality. Unlike just a few years ago, where we had at most one computer per person, we now routinely live and work in environments populated by dozens of "intelligent" devices. Increasingly, these devices have the ability to interconnect with one another and with software-based services, holding out the promise of flexible interoperability and integrated functionality. As these interconnected devices and services proliferate, we must focus on the question: how will we discover, make sense of, and ultimately use, the functionality around us?

The workshop will explore the problems that we will face building systems for this new world.

Specific questions we hope to address include:

• How will users locate, understand, assemble, and use the devices and services they need to accomplish their tasks?
• How can applications, devices, and services be designed so that they can integrate their functionality to assist users' tasks?
• How do we represent and effectively use contextual information about devices, services, users, and the environment?

The focus for this workshop is on the design and construction of services (including devices) and service frameworks to support a positive user experience. Participants will be selected based on 2-page position papers describing their interest in and experience with the topic.

Interactive Television (iTV) services are gaining acceptance in consumer marketplaces worldwide. Analyst predictions even suggest that interactive TVs and digital set-top boxes will overtake personal computers as the primary means of accessing internet content and e-commerce applications.

This one-day workshop is aimed at defining the design space that is represented by this medium and, importantly, identifying the strategies required to design successful iTV services. Currently, users may use a range of iTV services including: electronic program guides, text services, internet sites, email, e-commerce applications, and games. But, do design conventions that originate from desktop computing applications or web sites apply to iTV? Based on their own practical experiences, workshop participants will analyze the design approaches required by different kinds of iTV applications, and consider which applications are likely to add real value to users. Workshop participants will also work together to define a research agenda for the iTV community and outline the skills and disciplines required to make the most of this new platform for interactivity. The workshop will bring together a diverse range of perspectives and include members of the traditional HCI and interaction design communities as well as people from broadcasting and TV production organizations. Participants will be expected to have practical experience of researching or developing iTV services and be able to come to the workshop with examples and insights to share. Workshop participants will be selected on the strength of submitted position statements (of at least one page).

The increasing success and popularity of the Internet makes this a critical time to examine elements that can cause online user interactions to be a success or a dismal failure. One of the most important of these elements, trust, has been identified as critical in ensuring a successful online interaction. While virtual experiences in online systems eliminate or minimize face to face contact, human trust is still essential for the experience to be effective. Consequently, online interface designers must be able to design elements into their web sites that engender trust. We have identified two online contexts upon which to focus during the workshop. These are: ecommerce and health care information systems.

The ultimate goal of this workshop is to begin the discussion by identifying a vocabulary with which to talk about online trust and creating frameworks for understanding online trust.

The workshop goals are to:

• Identify and define key terms and concepts related to online trust.
• Briefly review and synthesize existing literature on online trust
• Develop new conceptual frameworks for viewing online trust
• Identify potential areas for future online trust research and design trials

The workshop is limited to 15 participants. Those interested should submit a 1-2 page paper describing their ideas related to the goals of the workshop by March 1. Participants are expected to read all position papers and other selected papers before the workshop and to come prepared to discuss specific ideas related to the goals of the workshop.
