PC-Access is a system which combines both hardware and software in order to provide multimodal feedback in a Microsoft Windows graphical interface and within its applications. We propose two versions of PC-Access: one which offers sound feedback with an enhanced drawing tablet and another in which tactile stimuli are synthesized by a haptic pointing device. When using the second version, the user will be able to perceive the interface objects (e.g, icons, menus, windows) as well as actions (e.g, moving, re-sizing). Thus, PC-Access offers auditory information (non-verbal sounds and voice synthesis), reinforced by the sense of touch which in turn helps to direct manipulation.

The emergence of the World Wide Web has made it possible for individuals with appropriate computer and telecommunications equipment to interact as never before. An explosion of next-generation information systems are flooding the commercial market. This cyberspace convergence of data, computers, networks, and multimedia presents exciting challenges to interface designers. However, this "new technology frontier" has also created enormous roadblocks and barriers for people with disabilities. This panel will discuss specific issues, suggest potential solutions and solicit contributions required to design an accessible Web interface that includes people with disabilities.

CAISARTS (Conceptual, Analytical, and Implementation Scheduling Advice for Real-Time Systems) is a rule-based system used by real-time application designers to obtain expert assistance for all aspects of the design related to scheduling: granularity of tasks, allocation of tasks, choice and analysis of scheduling paradigm, analysis of overheads of particular operating systems and scheduling paradigms, and code templates for tasks. The rule base is partitioned; subsets of the rule base can be selected for firing, thus enabling the user to ask CAISARTS for advice and analysis relevant for different phases of the design. In contrast to existing real-time tools, CAISARTS attempts to cover the entire design process related to scheduling without focusing on, for example, solely schedulability analysis. A unique feature of CAISARTS is that its rule base is extensible by the user-a graphical interface is used to add new rules as new real-time results are identified. Challenges in the design of the initial rule set include how to design and partition the rule base so that it can be both easily modifiable and readily usable by the user in choosing rules to fire; how to encode rules that are inherently contradictory; how to encode ambiguous knowledge; and how to make the rules both comprehensive and precise. The effectiveness of CAISARTS is shown through its use on a representative distributed real-time system scenario with end-to-end constraints.

Automating any part of the userinterface design and evaluation process can help reduce development costs. This paper presents a metric-based tool called AIDE (semi-Automated interface Designer and Evaluator) which assists designers in creating and evaluating layouts for a given set of interface controls. AIDE is an initial attempt to demonstrate the potential of incorporating metrics into userinterface development tools. Analyzing the interfaces produced using AIDE provides encouraging feedback about the potential of this technique.

We describe a new user-interface metaphor for immersive virtual reality - the virtual tricorder. The virtual tricorder visually duplicates a six-degrees-of-freedom input device in the virtual environment. Since we map the input device to the tricorder one-to-one at all times, the user identifies the two. Thus, the resulting interface is visual as well as tactile, multipurpose, and based on a tool metaphor. It unifies many existing interaction techniques for immersive virtual reality.

Morphic is a userinterface construction environment that strives to embody directness and liveness. Directness means a userinterface designer can initiate the process of examining or changing the attributes, structure, and behavior of userinterface components by pointing at their graphical representations directly. Liveness means the userinterface is always active and reactive - objects respond to user actions, animations run, layout happens, and information displays update continuously. Four implementation techniques work together to support directness and liveness in Morphic: structural reification, layout reification, ubiquitous animation, and live editing.

Engineering models of human performance permit some aspects of usability of interface designs to be predicted from an analysis of the task, and thus can replace to some extent expensive user testing data. The best developed such tools are GOMS models, which have been shown to be accurate and effective in predicting usability of the procedural aspects of interface designs. This paper describes a computer-based tool, GLEAN, that generates quantitative predictions from a supplied GOMS model and a set of benchmark tasks. GLEAN is demonstrated to reproduce the results of a case study of GOMS model application with considerable time savings over both manual modeling as well as empirical testing.

Members of geographically distributed work groups often complain of a feeling of isolation and of not knowing 'who is around'. Argohalls attempt to solve this problem by integrating video icons, clustered into groups representing physical hallways, into the Argo telecollaboration system. Argo users can 'hang out' in hallways in order to keep track of the co-workers on their projects, and they can roam other hallways to 'run into' whoever happens to be there.
