IEEE International Workshop on Digital Game and Intelligent Toy Enhanced Learning (DIGITEL)

作者： Gudrun Kellner Andreas Weißenbacher Institute of Software Technology and Interactive Systems University of Technology Vienna Vienna Austria Inst. of Software Technol. & Interactive Syst. Vienna Univ. of Technol. Vienna Austria

Learning strategies are typically tested in rather conventional test settings, using questionnaires or observation as a method of information acquisition. However, such conventional test settings are far from the test taker's everyday life situation and might therefore evoke stress. Embedding a learning strategies test into an educational computer game, provides several advantages over the conventional testing procedure: The test takers can stay in their familiar learning environment and even learn something during the process of being tested. We conducted an explorative study by testing 24 pupils, comparing the outcome of a conventional learning strategies test conducted by a psychologist with the results obtained by our GETOLS method. The high similarity of results strongly supports our approach.

systems development needs to reconcile views from many roles, such as domain experts and engineers. A particular challenge is the multitude of models for requirements and quality, which can get time consuming and error prone to trace, change, and verify. In this paper we introduce an ontology-supported component-based systems engineering approach for the production automation domain that describes explicitly stakeholder quality requirements and traces design decisions to generate new system and software versions that implement these requirements. The ontology approach is expected to allow continuous modeling and extracting model views for all roles involved to a) improve the quality assurance of system requirements;b) support more explicit feedback on the quality of intermediate models during systems development;and c) provide better auditing capabilities of the systems development process. Based on an industry case study, we describe the ontology concept of the system, the development process, and how software quality can be measured and improved. Copyright 2008 ACM.

Decision makers in safety-critical domains rely on data from dependable information systems. Traditional time- and safety-critical information systems, such as traffic management systems, have been using proprietary point-to-point data links, which are very dependable, but also time-consuming and costly to change due to the need to manually adapt a multitude of deployed systems. In this paper we introduce a model-driven architecture (MDA) system approach that describes explicitly stakeholder quality requirements on dependable data links between systems for decision support and generates new system versions that implement these requirements. The MDA approach is expected to a) improve the quality (assurance) of system requirements;b) support more explicit feedback on the quality of intermediate models during systems development;and c) provide better auditing capabilities of the systems development process. Based on an industry case study we describe the MDA concept of the system, the development process, and how software quality can be measured and improved. © 2007 IEEE.

Colour segmentation-based computation of dense optical flow with application to video object segmentation

OGAI Journal (Oesterreichische Gesellschaft fuer Artificial Intelligence) 2005年第1期24卷 11-15页

作者： Bleyer, Michael Gelautz, Margrit Rhemann, Christoph Vienna University of Technology Inst. Software Technol. I.S. Interactive Media Systems Group Favoritenstrasse 9-11/188/2 A-1040 Vienna Austria

We propose a method for the computation of dense optical flow fields between two images of a video sequence. In a preprocessing step, the algorithm segments the reference frame into regions of homogenous colour. The flow vectors inside such regions are supposed to vary smoothly, while motion boundaries are assumed to coincide with boundaries of those regions. Given an initial affine motion model for each segment, the algorithm extracts a set of affine layers, which represent the dominant image motion, in a clustering procedure. Each segment is then assigned to one of those layers in order to optimize a global cost function. The cost function aims at generating smooth flow fields and models occlusions in both images. Layer extraction and assignment are then iteratively applied until convergence. Since the algorithm assigns segments that undergo the same affine motion to the same layer, the proposed method can equivalently be regarded as motion segmentation algorithm. Strong experimental results are achieved, especially in regions of poor texture and close to motion boundaries, where conventional methods often show poor performance.

Facilitating knowledge maintenance of clinical guidelines and protocols

Studies in Health technology and Informatics 2004年第PT 1期107卷 57-61页

Clinical protocols and guidelines are widely used in the medical domain to improve disease management techniques. Different software systems are in development to support the design and the execution of such guidelines. The bottleneck in the guideline software developing process is the transformation of the textbased clinical guidelines into a formal representation, which can be used by the execution software. This paper introduces a method and a tool that was designed to provide a solution for that bottleneck The so-called Guideline Markup Tool (GMT) facilitates the translation of guidelines into a formal representation written in XML. This tool enables the protocol designer to create links between the original guideline and its formal representation and ease the editing of guidelines applying design patterns in the form of macros. The usefulness of our approach is illustrated using GMT to edit Asbru protocols. We performed a usability study with eight participants to examine the usefulness of the GMT and of the Asbru macros, which showed that the proposed approach is very appropriate to author and maintain clinical guidelines. © 2004 IMIA.

In recent years the Olympic Games have undergone vast criticism due to perceived subjective scoring in judged events, as for example figure skating and gymnastics. Judges' scores may be influenced by favoritism, human error, or possibly corruption. Audience participation in scoring represents a promising approach to meet these problems. In this paper we present an audience voting system that utilizes the natural behavior of sports spectators: clapping and cheering. The system consists of wireless motion sensors and microphones that enable spectators to cast their vote in real time. The sensors are worn by audience members and determine the clapping frequency of each participant. This facilitates continuous influence on the score throughout an athlete's performance. The audience score is presented on wall-sized stadium displays and might be contrasted with the judges' scores to encourage audience engagement. © 2004 ACM.
