This paper describes the ongoing work on mobile teleradiology systems in the EC-funded project MTM. The current development is based on the CHILI software architecture, which provides a PACS and teleradiology infrastructure. The authors collected user requirements in a first step. Appropriate hardware has been selected based on these requirements. Dedicated software versions of CHILI have been realized on selected PDA hardware. The target of the MTM project is to use UMTS for wireless communication. A wireless local area network (WLAN, IEEE 802.11b) is currently used, as UMTS is not yet available. We have implemented the full functionality of a regular workstation in the initial version of the software. A first evaluation found out that such a high level of functionality is both difficult to implement in a useful manner, but also not really requested by medical users in an actual situation. Future software versions, therefore, need to focus more on usability issues and core functionality. © 2001, Elsevier B.V.

Multimodal interfaces are being developed that permit our highly skilled and coordinated communicative behavior to control system interactions in a more transparent and flexible interface experience than ever before. As applications become more complex, a single modality alone does not permit varied users to interact effectively across different tasks and usage environments [11]. However, a flexible multimodal interface offers people the choice to use a combination of modalities, or to switch to a better-suited modality, depending on the specifics of their abilities, the task, and the usage conditions. This paper will begin by summarizing some of the primary advantages of multimodal interfaces. In particular, it will discuss the inherent flexibility of multimodal interfaces, which is a key feature that makes them suitable for universal access and mobile computing. It also will discuss the role of multimodal architectures in improving the robustness and performance stability of recognition-based systems. Data will be reviewed from two recent studies in which a multimodal architecture suppressed errors and stabilized system performance for accented nonnative speakers and during mobile use. The paper will conclude by discussing the implications of this research for designing multimodal interfaces for the elderly, as well as the need for future work in this area. © Copyright 2001 ACM.

International Conference on Information Visualisation (IV)

Users who must combine demographic, economic or other data in a geographic context are often hampered by the integration of tabular and map representations. Static, paper-based solutions limit the amount of data that can be placed on a single map or table. By providing an effective user interface, we believe that researchers, journalists, teachers, and students can explore complex data sets more rapidly and effectively. This paper presents Dynamaps, a generalized map-based information visualization tool for dynamic queries and brushing on choropleth maps. Users can use color coding to show a variable on each geographic region, and then filter out areas that do not meet the desired criteria. In addition, a scatterplot view and a details-on-demand window support overviews and specific fact-finding.

IEEE Symposium on human Centric Computing Languages and Environments

In exploring how to make programming easier for non-programmers, research into end-user environments has traditionally been concerned with designing better human-computer interaction. That traditional focus has left open the question of how end-user environments might support human-human interaction. Especially in situations in which end-user environments are enlisted to facilitate learning, we hypothesize that a key benefit may be their ability to mediate conversations about a domain of interest. In what ways might end-user environments support human communication, and what design features make them well-suited to do so? Drawing on ethnographic studies of an undergraduate algorithms course in which students constructed and presented algorithm visualizations, we develop a provisional framework of six communicative dimensions of end-user environments: programming salience, typeset fidelity, story content, modifiability, controllability and referencability. To illustrate the design implications of these dimensions, we juxtapose conventional algorithm visualization technology with a prototype end-user environment specifically designed to facilitate communication about algorithms. By characterizing those aspects of end -user environments that impact social interaction, our framework provides an important extension to T.R.G. Green and M. Petre's (1996) cognitive dimensions.

This paper presents PROMAN (PROduction MANagement), a software solution applied to production management optimization for a company with an extensive variety of human and material resources and with a nonlinear production chain. The adopted solution is based on the use of generic office applications that will improve the usability of the system. On the other hand, a specific module for the visualization of Gantt charts has been developed that adjusts to the present application and to user requirements. "Associacio/spl acute/ Shalom", an SME that needs the solution that we present, will use the results of this project.

Cognitive Feedback Training using 3D Binocular Eye Tracker

Proceedings of the human Factors and Ergonomics Society Annual Meeting 2001年第26期45卷 1838 - 1842页

Studies in visual search have shown that feedback training can improve visual inspection performance (speed and accuracy), provided it is given in a timely and appropriate manner. Traditionally, performance feedback, i.e. information about the outcome, serves as the basis of most feedback training schemes. Other forms of feedback, which provide search strategy information, may have a role to play in improving inspection performance. This form of feedback is referred to as ‘cognitive feedback’. This paper describes the setup for collecting and analyzing eye movements using a 3D binocular eye tracker, which serves as a tool for providing cognitive feedback training. It also emphasizes the various technical issues related with eye tracker integration and further discusses the use of a new 3D-fixation recognition algorithm.

Professor John Belcher developed a series of short videos with animation and text of selected experiments to properly demonstrate the phenomena of electromagnetism. Such 3D animations are visually compelling, instilling in the student both a sense of wonder about the phenomena and a mental model of why and how it works. The products of these approach includes video clips of demonstrations, 3D animations of these demonstration which display time changing field-lines as a guide to understanding their dynamical effects and Java applets which allow the student to actively construct and animate 2D field lines for varying configurations of sources. These technologies are also implemented to develop animations for Faraday's insights, using video clips.

human-robot interaction technologies are very important components in the human centered system. Among many human-robot interaction technologies, the intention reading of a user plays an important role in human centered systems. In the paper, we focus on the use of intention reading in rehabilitation robots, and implement its capability for the wheelchair-based robotic arm system, called KARES (KAIST Rehabilitation Engineering Service System) II. For effective intention reading, visual servoing by using an image sequence of user's face or control by using EMG signals of user's arm are applied to KARES II. Specially, it is shown that soft computing techniques are very effective for intention reading.

This paper presents for the first time fabrication and initial measurements of an electrophoresis stage integrated with a novel inline electrochemical detection system. This detector system can be easily incorporated into plastic substrates and has less complex fabrication procedure compared to fluorescent detection systems. Potentiostatic and Open potential modes of detection are demonstrated. Techniques used to eliminate gas evolution at the detection electrodes and to reduce noise are discussed. Noise levels of 0.7 pA on a signal of 5 nA and drift in signal of 1.18 pA/s were measured for the potentiostatic mode of detection for the field and buffer concentration mentioned. Open potential mode had noise levels of 9.1 mV on a signal of 800 mV and a drift in signal of 0.22 mV/s. The potentiostatic mode was determined to be more stable based on the S/N ratios. Separation and detection of few biologically important compounds along with few electrochemical tags are demonstrated. Detection limits of 14.5 amol were measured for the potentiostatic mode of detection.
