We examine opportunities for ubiquitous technologies in retail shopping, jewelry shopping in this case, to supplement the unique information needs inherent to physical trials of tactile products. We describe an iterative design approach to develop a mirror system that records and matches images across jewelry trials called the Countertop Responsive Mirror. The key technological distinction of our system from prior technologies is the use of "matched access," which automatically retrieves images that match a scene shown in separately accessed images. This not only helps shoppers compare jewelry but also promotes interactions among all parties during shopping. We report qualitative findings from multiple field trials of the system. This paper contributes to a body of research on the design and introduction of new technologies into retail shopping that provide value to all users without disruption to their normative practices and behaviors.

In 1987 Brundtland defined sustainable development as "development that meets the needs of the present without compromising the ability of future generations to meet their own needs." [1] The simplicity of this statement is seductive - but what really constitutes sustainable development, and defines the role of user experience research and design within it, is at best elusive. This workshop aims at bringing together experts and researchers in User Experience and related disciplines for a hands-on discussion of questions, insights, and approaches in designing for a sustainable future.

This paper reports on the results of studies of task management to support the design of a task list manager. We examined the media used to record and organize to-dos and tracked how tasks are completed over time. Our work shows that, contrary to popular wisdom, people are not poor at prioritizing. Rather, they have well-honed strategies for tackling particular task management challenges. By illustrating what factors influence task completion and how representations function to support task management, we hope to provide a strong foundation for the design of a personal to-do list manager. We also present some preliminary efforts in this direction.

According to usability experts, the top user issue for Web sites is difficult navigation. We have been developing auto-mated usability tools for several years, and here we describe a prototype service called InfoScent™ Bloodhound Simula-tor, a push-button navigation analysis system, which auto-matically analyzes the information cues on a Web site to produce a usability report. We further build upon previous algorithms to create a method called Information Scent Absorption Rate, which measures the navigability of a site by computing the probability of users reaching the desired destinations on the site. Lastly, we present a user study involving 244 subjects over 1385 user sessions that show how Bloodhound correlates with real users surfing for in-formation on four Web sites. The hope is that, by using a simulation of user surfing behavior, we can reduce the need for human labor during usability testing, thus dramatically lower testing costs, and ultimately improving user experience. The Bloodhound Project is unique in that we apply a concrete HCI theory directly to a real-world prob-lem. The lack of empirically validated HCI theoretical model has plagued the development of our field, and this is a step toward that direction.
