Production reconfiguration has been well recognized as an effective means of planning production processes for product families. The major challenge of production reconfiguration lies in the handling of numerous constraints associated with product and process variety. This paper develops a constraint satisfaction approach to deal with production reconfiguration. It introduces a domain model to capture the decision variables and a systematic procedure to tackle constraint identification, representation and evaluation. An industrial example of textile spindle is used to illustrate the feasibility and potential of the domain-based constraint satisfaction problem model for production reconfiguration.

Historically, the ACM Multimedia Conference is split into a "technical" program and an "arts" program. These programs sometimes seem completely separate from one another, victims of a "semantic gap" between disciplines. The goal of this panel is to create a space in which scientists learn from artists, and arts from science. We need to discover new connections between modalities of research. In order to create the most exciting and powerful future forms of interactive multimedia systems, the ones that will create the most beneficial broader impact on humanity, we need to foster new collaborations between artists and scientists. This panel seeks to bridge the great divide of language and communities that has fragmented us, creating a new space for developing connections between the arts and sciences of multimedia research, as embodied through the artists and scientists of ACM Multimedia. The goal is to make this conference a premier site for catalyzing emergent connections. Among the ancient Greeks, the techne, which included the sciences, were based in the arts. Our modes of knowledge production have since separated and grown alienated. "What weird stuff are those people doing?" To bridge the divide, we must understand and acknowledge differences, and use this as a basis for discovering common ground. In the sciences, knowledge is constructed empirically, through hypotheses and validations. Aesthetics and concepts play essential roles in how works of art are formulated to stimulate experiences. Where do these aims intersect and how might they inform each other? In this conference, one track develops pattern recognition methods for content analysis and retrieval. Another develops network and system techniques. Applications invoke these methods in usable systems. Human-centered multimedia serves as a bridge connecting human experiences with algorithmic methods. The interactive art program develops new concepts of how multimedia can function culturally, amidst society,

The tutorial presents state-of-the-art visualization techniques inspired by traditional technical and medical illustrations. Such techniques exploit the perception of the human visual system and provide effective visual abstractions to make the visualization clearly understandable. Visual emphasis and abstraction has been used for expressive presentation from prehistoric paintings to nowadays scientific and medical illustrations. Many of the expressive techniques used in art are adopted in computer graphics, and are denoted as illustrative or non-photorealistic rendering. Different stroke techniques, or brush properties express a particular level of abstraction. Feature emphasis or feature suppression is achieved by combining different abstraction levels in illustrative rendering. Challenges in visualization research are very large data visualization as well as multi-dimensional data visualization. To effectively convey the most important visual information there is a significant need for visual abstraction. For less relevant information the dedicated image space is reduced to enhance more prominent features. The discussed techniques in the context of scientific visualization are based on iso-surfaces and volume rendering. Apart from visual abstraction, i.e., illustrative representation, the visibility of prominent features can be achieved by illustrative visualization techniques such as cut-away views or ghosted views. The structures that occlude the most prominent information are suppressed in order to clearly see more interesting parts. A different smart way to provide information on the data is using exploded views or other types of deformation. Furthermore intuitive feature classification via 3D painting and manipulation with the classified data including label placement is presented. Discussed non-photorealistic and illustrative techniques from visualization and graphics are shown from the perspective as tools for illustrators from medicine, botany, archeology

Two video-based human-computer interaction tools are introduced that can activate a binary switch and issue a selection command. "BlinkLink," as the first tool is called, automatically detects a user's eye blinks and accurately measures their durations. The system is intended to provide an alternate input modality to allow people with severe disabilities to access a computer. Voluntary long blinks trigger mouse clicks, while involuntary short blinks are ignored. The system enables communication using "blink patterns:" sequences of long and short blinks which are interpreted as semiotic messages. The second tool, "EyebrowClicker," automatically detects when a user raises his or her eyebrows and then triggers a mouse click. Both systems can initialize themselves, track the eyes at frame rate, and recover in the event of errors. No special lighting is required. The systems have been tested with interactive games and a spelling program. Results demonstrate overall detection accuracy of 95.6% for BlinkLink and 89.0% for EyebrowClicker. © Springer-Verlag 2003.

A prototype concurrent engineering tool has been developed for the preliminary design of composite topside structures for modern navy warships. This tool, named GELS for the Concurrent Engineering of Layered Structures, provides designers with an immediate assessment of the impacts of their decisions on several disciplines which are important to the performance of a modern naval topside structure, including electromagnetic interference effects (EMI), radar cross section (RCS), structural integrity, cost, and weight. Preliminary analysis modules in each of these disciplines are integrated to operate from a common set of design variables and a common materials database. Performance in each discipline and an overall fitness function for the concept are then evaluated. A graphical user interface (GUI) is used to define requirements and to display the results from the technical analysis modules. Optimization techniques, including feasible sequential quadratic programming (FSQP) and exhaustive search are used to modify the design variables to satisfy all requirements simultaneously. The development of this tool, the technical modules, and their integration are discussed noting the decisions and compromises required to develop and integrate the modules into a prototype conceptual design tool.

Icons are used increasingly in interfaces because they are compact "universal" pictographic representations of computer functionality and processing. Animated icons can bring to life symbols representing complete applications or functions within an application, thereby clarifying their meaning, demonstrating their capabilities, and even explaining their method of use. To test this hypothesis, we carried out an iterative design of a set of animated painting icons that appear in the HyperCard tool palette. The design discipline restricted the animations to 10 to 20 second sequences of 22×20 pixel bit maps. User testing was carried out on two interfaces - one with the static icons, one with the animated icons. The results showed significant benefit from the animations in clarifying the purpose and functionality of the icons. ©1991 ACM.

This paper describes and evaluates the design of four virtual controllers for use in rotating three-dimensional objects using the mouse. Three of four of these controllers are "new" in that they extend traditional direct manipulation techniques to a 3-D environment. User performance is compared during simple and complex rotation tasks. The results indicate faster performance for complex rotations using the new eontinuoos axes controllers compared to more traditional slider approaches. No significant differences in accuracy for complex rotations were found across the virtual controllers. A second study compared the best of these four virtual controllers (the Virtual Sphere) to a control device by Evans, Tanner and Wein. No significant differences either in time to complete rotation task or accuracy of performance were found. All but one subject indicated they preferred the Virtual Sphere because it seemed more "natural". © 1988 ACM.
