Not even the nascent state of the Web can excuse the amateurish lack of usability of today's eCommerce initiatives. The sites we evaluated demonstrated a fundamental failure to incorporate decades-old principles of software design. But as the novelty of doing business on the Web gives way to demands for basic quality, companies will have to get serious about user experience.

As part of a new CHI Sustainability Community, focused on environmental sustainability, this panel will discuss specific ways in which HCI research will be critical in finding solutions to this global challenge. While research to date has primarily focused on the end consumer, the panel will be challenged with enlarging the discussion to include the designer as a target user and to consider interfaces and interactions that support sustainable design and sustainable manufacturing, as well as sustainable consumption. Specifically, to make real progress, we seek to enumerate ways that HCI needs to grow, as well as to find ways that can help more HCI researchers to become involved.

Engaging occupants in conservation efforts is a key part of reducing our ecological footprint. To this end, we have developed the Aware Living Interface System (ALIS), an integrated in-home system that supports residents in awareness of resource use, facilitates efficient control of house systems, and encourages conservation in daily activities. Initial responses from deployments in two high-profile sustainable homes indicate the potential and challenges involved in supporting sustainable living.

Collaboration often relies on all group members having a shared view of a single-user application. A common situation is a single active presenter sharing a live view of her workstation screen with a passive audience, using simple hardware-based video signal projection onto a large screen or simple bitmap-based sharing protocols. This offers simplicity and some advantages over more sophisticated software-based replication solutions, but everyone has the exact same view of the application. This conflicts with the presenter\'s need to keep some information and interaction details private. It also fails to recognize the needs of the passive audience, who may struggle to follow the presentation because of verbosity, display clutter or insufficient familiarity with the application. Views that cater to the different roles of the presenter and the audience can be provided by custom solutions, but these tend to be bound to a particular application. In this paper we describe a general technique and implementation details of a prototype system that allows standardized role-specific views of existing single-user applications and permits additional customization that is application-specific with no change to the application source code. Role-based policies control manipulation and display of shared windows and image buffers produced by the application, providing semi-automated privacy protection and relaxed verbosity to meet both presenter and audience needs.

Notification systems attempt to deliver current, important information to
the computer screen in an efficient and effective manner. All notification
systems require that the user attends to them to at least some degree if they
are to succeed. Examples of notification systems include instant messaging
systems, system and user status updates, email alerts and news and stock
tickers. The benefits of notification systems are numerous, including rapid
availability of important information, access to nearly instantaneous
communication and heightened awareness of the availability of personal
contacts. While the popularity of these systems has skyrocketed in recent
years, the effects of incoming notifications on ongoing computing tasks have
been relatively unexplored. The investigation of the costs, benefits and the
optimal display of instant messages and all notifications in the context of
desktop or mobile computing tasks falls in the general arena of psychological
research on alerting and disruptions, but also requires research contributions
from design, computer science and information visualization. To date, much of
the psychological research on interruption leverages theoretical task
constructions. In this special issue, we focus on the nature of interruptions
such as messaging while computing and how to optimize the user experience.

Bartram, Lyn, Ware, Colin and Calvert, Tom W. (2003): Moticons:: detection, distraction and task. In International Journal of Human-Computer Studies, 58 (5) pp. 515-545.
In this paper, we describe an empirical investigation of the utility of
several perceptual properties of motion in information-dense displays applied
to notification. Notification relates to awareness and how dynamic information
is communicated from the system to the user. Key to a notification technique is
how easily the notification is detected and identified. Our initial studies
show that icons with simple motions, termed moticons, are effective coding
techniques for notification and in fact are often better detected and
identified than colour and shape codes, especially in the periphery. A
subsequent experiment compared the detection and distraction effects of
different motion types in several task conditions. Our results reveal how
different attributes of motion contribute to detection, identification and
distraction and provide initial guidelines on how motion codes can be designed
to support awareness in information-rich interfaces while minimizing unwanted
side effects of distraction and irritation.

Many information structures are represented as two-dimensional networks (connected graphs) of links and nodes. Because these network tend to be large and quite complex, people often prefer to view part or all of the network at varying levels of detail. Hierarchical clustering provides a framework for viewing the network at different levels of detail by superimposing a hierarchy on it. Nodes are grouped into clusters, and clusters are themselves place into other clusters. Users can then navigate these clusters until an appropriate level of detail is reached. This article describes an experiment comparing two methods for viewing hierarchically clustered networks. Traditional full-zoom techniques provide details of only the current level of the hierarchy. In contrast, fisheye views, generated by the "variable-zoom" algorithm described in this article, provide information about higher levels as well. Subjects using both viewing methods were given problem-solving tasks requiring them to navigate a network, in this case, a simulated telephone system, and to reroute links in it. Results suggest that the greater context provided by fisheye views significantly improved user performance. Users were quicker to complete their task and made fewer unnecessary navigational steps through the hierarchy. This validation of fisheye views in important for designers of interfaces to complicated monitoring systems, such as control rooms for supervisory control and data acquisition systems, where efficient human performance is often critical. However, control room operators remained concerned about the size and visibility tradeoffs between the fine room operators remained concerned about the size and visibility tradeoffs between the fine detail provided by full-zoom techniques and the global context supplied by fisheye views. Specific interface features are required to reconcile the differences.

(ed.) Proceedings of the 8th annual ACM symposium on User interface and software technology November 15 - 17, 1995, Pittsburgh, Pennsylvania, United States. pp. 207-215.
Navigating and viewing large information spaces, such as hierarchically-organized networks from complex real-time systems, suffer the problems of viewing a large space on a small screen. Distorted-view approaches, such as fisheye techniques, have great potential to reduce these problems by representing detail within its larger context but introduce new issues of focus, transition between views and user disorientation from excessive distortion. We present a fisheye-based method which supports multiple focus points, enhances continuity through smooth transitions between views, and maintains location constraints to reduce the user's sense of spatial disorientation. These are important requirements for the representation and navigation of networked systems in supervisory control applications. The method consists of two steps: a global allocation of space to rectangular sections of the display, based on scale factors, followed by degree-of-interest adjustments. Previous versions of the algorithm relied solely on relative scale factors to assign size; we present a new version which allocates space more efficiently using a dynamically calculated degree of interest. In addition to the automatic system sizing, manual user control over the amount of space assigned each area is supported. The amount of detail shown in various parts of the network is controlled by pruning the hierarchy and presenting those sections in summary form.
