Collaborative corporate requirements engineering and system specification demands modelling approaches that all stakeholders can understand and apply. Using traditional methods, an IT organization often experiences frustrating communication and competency issues. Current processes lack adequate tool support for networked and complex projects. We present a tool-chain for model-based requirements engineering and a visual specification of interactive systems. Through a substitution of text-based artefacts, stakeholders are able to model systems with high user interface usability and functional quality in less time. © 2007 IADIS

We seek to close the gap between software engineering (SE) and human-computer interaction (HCI) by indicating interdisciplinary interfaces throughout the different phases of SE and HCI lifecycles. As agile representatives of SE, Extreme Programming (XP) and Agile Modeling (AM) contribute helpful principles and practices for a common engineering approach. We present a cross-discipline user interface design lifecycle that integrates SE and HCI under the umbrella of agile development. Melting IT budgets, pressure of time and the demand to build better software in less time must be supported by traveling as light as possible. We did, therefore, choose not just to mediate both disciplines. Following our surveys, a rather radical approach best fits the demands of engineering organizations. © 2007 Thomas Memmel, Fredrik Gundelsweiler, Harald Reiterer.

CandidTree: Visualizing structural uncertainty in similar hierarchies

Information Visualization 2007年第3期6卷 233-246页

Most visualization systems fail to convey uncertainty within data. To provide a way to show uncertainty in similar hierarchies, we interpreted the differences between two tree structures as uncertainty. We developed a new interactive visualization system called CandidTree that merges two trees into one and visualizes two types of structural uncertainty: location and sub-tree structure uncertainty. Since CandidTree can visualize the differences between two tree structures, we conducted a series of user studies with tree-comparison tasks. First a usability study was conducted to identify major usability issues and evaluate how our system works. Another qualitative user study was conducted to see if biologists, who regularly work with hierarchically organized names, are able to use CandidTree, and to assess the uncertainty metric we used. A controlled experiment with software engineers was conducted to compare CandidTree with WinDiff, a traditional files and folders comparison tool. The results showed that users performed better with CandidTree. Furthermore, CandidTree received better satisfaction ratings and all users preferred CandidTree to WinDiff. © 2007 Palgr aveMacmillan Ltd. All rights reserved.

作者： Giancarlo Iannizzotto Francesco La Rosa VisiLab Computer Vision and Human-Computer Interaction Laboratory Engineering University of Messina Messina Italy

In this paper we describe a pen-based user interface for easy and natural user interaction with a wall projection display. VisualPen is a vision-based system for real-time detection and tracking of a pen that completely replaces mouse and keyboard. The low computational complexity of its algorithms renders it easy to implement with low-cost, low-power embedded hardware, thus allowing portability and integrability. The architecture of the system is described, and experimental results are presented and commented.

Based on many experiences of developing interactive systems by the authors, a framework for the description and analysis of interaction has been developed. The dimensions of this multimodal interaction space have been identified as sensory modalities, modes and levels of interaction. To illustrate and validate this framework, development of multimodal interaction styles is carried out and interactions in the real world are studied, going from theory to practice and back again. The paper describes the framework and two recent projects, one in the field of interactive architecture and another in the field of multimodal HCI research. Both projects use multiple modalities for interaction, particularly movement based interaction styles. © Springer-Verlag London Limited 2007.

This paper addresses the problem of making text mining results more comprehensible to humanities scholars, journalists, intelligence analysts, and other researchers, in order to support the analysis of text collections. Our system, FeatureLens1, visualizes a text collection at several levels of granularity and enables users to explore interesting text patterns. The current implementation focuses on frequent itemsets of n-grams, as they capture the repetition of exact or similar expressions in the collection. Users can find meaningful co-occurrences of text patterns by visualizing them within and across documents in the collection. This also permits users to identify the temporal evolution of usage such as increasing, decreasing or sudden appearance of text patterns. The interface could be used to explore other text features as well. Initial studies suggest that FeatureLens helped a literary scholar and 8 users generate new hypotheses and interesting insights using 2 text collections. Copyright 2007 ACM.

During the early stages of architectural training, tangibility plays an important role in developing spatial awareness. In such contexts, tangible user interfaces are believed to provide a significant advantage as they combine the affordances of both the physical and the digital world. We introduce CubeExplorer, a hybrid 3D conceptual aid that combines physical interaction and digital modeling in an effort to complement conventional architectural space-training tools (such as physical materials and digital CAD programs). Using a digital pen as an input mechanism, CubeExplorer lets users perform subtractive 3D geometric operations on a simple paper based cube model while observing the resulting model on a display. The tangibility of the model simplifies navigation and command execution, while the digital interface makes it easy for users to explore multiple alternative designs. To evaluate the potential of such an approach, we conducted a user study in a normal classroom environment where students were provided with physical (wooden block), hybrid (CubeExplorer), and virtual (FormZ) interfaces to complete the same assignment. Our evaluation showed that CubeExplorer combined the advantages of both digital and tangible media. The advantages of CubeExplorer over digital media were substantiated in a follow-up study comparing CubeExplorer and SketchUp in a similar building task. © IFIP International Federation for Information Processing 2007.

It is commonly acknowledged that 'smart' environments, interactive architecture and 'smart' homes will defi ne the next cutting edge in architectural research. Most critics agree that one of the fi rst problems that 'smart' homes will help to address is that of spiraling costs of healthcare and aging-in-place. This may be true for urban settings where there is the fi nancial feasibility for such technologies but what about rural America? It has been conclusively proven that rural America suffers from a lack of healthcare (delivery and access). Prior research (Mathew 2005) has also established that a rural home is different from an urban home. Will technologies designed for the urban home work in a rural setting? And do rural people carry the same attitudes and biases towards technology? This paper continues our research in the design of 'smart' rural environments. It summarizes fi ndings from focus group studies conducted in rural communities that help us to understand attitudes of people towards 'smart' technology. We will use these fi ndings to examine the feasibility of ubiquitous computing and 'smart' spaces in rural areas. In conclusion, we will present guidelines to help designers in the creation of technology to augment healthy aging in rural home settings.
