This work proposes a user-oriented approach as a basis for proper information visualization in the production automation area. A total consideration of the user consists of analyzing his tasks, context and profile. In order to implement this in the visualization process, an intelligent framework that is based on a multi agent system is developed. The advantage is that the tasks can be distributed to several small and manageable agents. The long term objective is to develop a working platform for the user-oriented information visualization.
A new interactive floorspace has been developed which uses modular nodes connected together to create a pressure-sensitive area of varying size and shape, giving it the potential to be integrated into an interactive e...

Within the software development process, reuse at the requirements level has become an increasingly more compelling notion. Following a human-centric approach, this work focuses on both requirements and design solution reuse using a design knowledge repository. In recent years, many improvements have been made to increase reuse through design knowledge repositories, but retrieval of knowledge in the context of design activities continues to be a formidable challenge. We propose a new system, called CERVi, to browse a repository through visualization by exploiting relationships between units of knowledge (in our case, claims). These relationships are key to finding the most appropriate reusable knowledge based on design conditions. Testing shows that CERVi enhances the design knowledge selection process and helps users proceed through structured design decision making. Our approach would be most useful to those interested in unlocking the potential of design knowledge reuse.

This paper presents a semantically structured resource of more than 1,600 Name Classes. This structure is based on the noun hypernymy hierarchies in WordNet, expanded and validated by corpus evidence collected from the World Wide Web. The set of seed examples provided by WordNet is boostrapped and the used to automatically construct an annotated training corpus for each Name Class. The resulting Named Entity resource enables a supervised Named Entity Recognizer to identify all the encoded Name Classes with high accuracy and without any human intervention.

This study was performed at the Clinic of Oral Medicine at Sahlgrenska university hospital in Gothenburg, Sweden. The focus of the study was to create a better system for handling images of the oral mucosa. The main goal was to determine if multi-layer design is a good method for this purpose. An interview session was performed to get a solid knowledge base of the users skills and needs. Based on the interviews and the methodology for multi-layer design a prototype was created. Seven different layers were put together and the basic were listed. The prototype uses an existing data source for images and patient data. In the work with the prototype the method has proven to be very useful so far. To prove the methodology further, several evaluations have to be performed and the prototype needs to be more thoroughly tested. Copyright 2004 ACM.

The genome organizations of eight phylogenetically distinct species from five mammalian orders were compared in order to address fundamental questions relating to mammalian chromosomal evolution. Rates of chromosome evolution within mammalian orders were found to increase since the Cretaceous-Tertiary boundary. Nearly 20% of chromosome breakpoint regions were reused during mammalian evolution;these reuse sites are also enriched for centromeres. Analysis of gene content in and around evolutionary breakpoint regions revealed increased gene density relative to the genome-wide average. We found that segmental duplications populate the majority of primate-specific breakpoints and often flank inverted chromosome segments, implicating their role in chromosomal rearrangement.

Search is an important factor in the visual inspection process. Previous studies have shown that the use of feedforward, or prior, information improves inspection performance. Although prior information on the nature of the defects that may be present and their possible locations has been widely used in visual inspection training, research has also shown positive results when process measures are used. One such process measure is visual search strategy. In an initial study, a dynamic display depicting an expert inspector's search strategy in the form of her visual scanpaths was presented to novice inspectors and resulted in a significant improvement in their inspection performance. A second study then compares three types of displays of visual search strategy: a static display, a dynamic display, and a hybrid display utilizing both static and dynamic presentation elements. The static display presents a static image that shows the regions of interest and scanpaths, essentially the systematic pattern in which the expert inspector performs the search. The dynamic feedforward display presents a cursor (a yellow dot) that moves across the screen and mimics the sequential indices (eye movement pattern) of the expert inspector. The cursor color changes to red at the location of a defect. The hybrid display is similar to the dynamic display, but also leaves a trace as the cursor moves along to the next area of interest. Thus, the history of the manner in which the expert inspector performed the search up to the current area of interest can be viewed in this display. The search task is machine paced and consists of inspecting 40 simulated Printed Circuit Board (PCB) images. Each board may have zero, one, two or three defects. A randomized complete block design is employed with the subjects' scores in a pilot study as the blocking factor. There are three groups of participants for the three types of displays. All of the groups receive the same feedforward information. The onl

Aircraft inspection is vital in assuring safety and reliability of the air transportation system. The human inspector performing visual inspection of aircrafts is the backbone of this process. Training is critical in achieving effective inspection performance. Studies of industrial inspection have established that feedforward training improves performance. Experienced inspectors are known to adopt a more effective inspection strategy than novice inspectors. Providing information regarding the search strategy of an expert, to novice inspectors may accelerate their adoption of a more effective search strategy. This paper describes an experimental study of the effect of providing such feedforward training on the inspection performance of novice inspectors.
