computer networks are pervasive and critical to the operation of today's businesses. While most of us take computer networks for granted, network managers who must configure, operate, and fix faults in computer networks face a daunting task that becomes more complex everyday. Ecological interface design has been shown to be a promising approach for complex systems such as power plants or petrochemical systems. computer networks are a very different work domain characterized by rapid technological change, extreme decentralization, and the existence of "soft" components. This paper presents the first work domain analysis of this new domain creating an abstraction hierarchy for general signal transfer systems and general computing networks. It shows how the abstraction hierarchy can be applied to this new domain and presents the initial work on an ecological interface design for network management.

The development of user interfaces based on vision and speech requires the solution of a challenging statistical inference problem: The intentions and actions of multiple individuals must be inferred from noisy and ambiguous data. We argue that Bayesian network models are an attractive statistical framework for cue fusion in these applications. Bayes nets combine a natural mechanism for expressing contextual information with efficient algorithms for learning and inference. We illustrate these points through the development of a Bayes net model for detecting when a user is speaking. The model combines four simple vision sensors: face detection, skin color, skin texture, and mouth motion. We present some promising experimental results.

Various alternative aircraft inspection methods are first discussed and advantages of using robots are analysed. ANDI (Automated NonDestructive Inspector) and CIMP (Crown Inspection Mobile Platform) are then described. Remote 3D stereoscopic visual inspection is outlined and algorithms developed for crack detection and surface and subsurface corrosion detection are described. Future development trends are also outlined.

Computation visualization or algorithm animation is becoming an increasingly popular and effective way of teaching, debugging, and analyzing algorithms. Over the past ten years, several algorithm animation systems have been produced. Proposed here is a new approach and framework for visualizing three-dimensional algorithms or computations. Implemented on a prototype algorithm animation system, this framework, termed the vector-guided view, produces insightful visualizations of three-dimensional computation by effectively solving the problems of 3D scene navigation. The creation of this framework was motivated by the desire to produce visualizations of an increasingly large and complex set of rendering algorithms now ubiquitous in the field of computer graphics. To show the potential of this framework, a dynamic visualization of a recursive ray-tracing program has been created. A brief summary of the algorithm animation system is presented.
One missing link between CAD and CAM is the lack of a systematic methodology for generating and evaluating alternative ways to manufacture a proposed design. To address this problem, we are developing a systematic app...

The Signal Processing Instructional Facility (SPIF lab) is an experiment in using in interactive multimedia for teaching concepts related to linear systems theory and signal processing. The goals of the SPIF lab are to augment, enhance, and interconnect sophomore, junior, and senior level courses with the common thread of linear systems and transforms by unifying the experimentation medium. In this fashion, physical phenomenon is returned to the forefront of engineering education. The laboratory features powerful Mathematica Notebooks (a form of hypertext) and interactive applications that use dedicated DSP microprocessors.

Creative practitioners rely on tools to capture and manage ideas as a foundational aspect of their work. However, we have little knowledge about how idea management practices vary in different creative domains. Combining insights from qualitative surveys (\(N\) \(\sim\)200) and follow-up in-depth interviews (\(n\) \(\sim\)60) with creative professionals from four domains (interaction design, research, music, and graphics) of creative work, we report on (1) how ideas are externalized in practitioners’ archives, (2) what they consider important when choosing tools to capture ideas, and (3) how these tool collections resemble and differ from each other. Our cross-domain study demonstrates that participants’ tool use reflects idea capture characteristic needs as well as domain-specific views about the creative process. We conclude with a discussion about capturing as an externalizing activity, practitioners’ use of the term ideas, and four suggestions for directions in the design of creativity support tools.
