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.

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.

In this paper, we introduce K-Menu, a keyword-based dynamic menu interface. When a user enters a keyword, a menu with items related to the keyword is constructed dynamically and presented to the user. We implemented K-Menu as a top-level interface for major mobile applications and mobile web services on a smartphone environment. A subsequent user test confirmed the task efficiency and the user acceptance of K-menu.

We present a real-time simulation of spray painting incorporated into a VR environment as an alternative training system for ship-building industries. The system allows the user to try out a painting work on life-size structures with a spray gun. Our goal is to provide a trainee realistic painting experience in real-time as well as to represent the thickness of the deposited paint on the surface for evaluation of his performance. The Gaussian model is used for a painting deposition model, and texture mapping technique is utilized to provide efficient visual feedback. We also present effective collision detection methods for a volume of spray paint particles. ©2007 IEEE.

We describe the latest development of a computer-based virtual reality environment for training interventional neuroradiology procedures. The system, NeuroCath (Neuroradiology Catheterization Simulator), includes extraction and construction of a vascular model from different imaging modalities that represents the anatomy of patient in a computationally efficient manner, and a finite element method (FEM) based physical model that simulates the interaction between the devices and neuro-vasculature. A realistic visual interface with multiple, synchronized windows and plenty of video control functions are developed. The latest version is also equipped with haptic feedback module that gives the sense of touch in real-time, and customizable vascular model so that trainer can understand the importance of vascular variations and practice. According to the validation in several clinical centers, 70%-75% of training features have been realized which makes the system well suitable for training of interventional neuroradiologists. © Springer-Verlag Berlin Heidelberg 2007.

Semantic web search for e-government: The case study of intrastat

Journal of Internet Technology 2007年第4期8卷 457-468页

作者： Markellos, Konstantinos Sakkopoulos, Evangelos Sirmakessis, Spiros Tsakalidis, Athanasios Research Academic Computer Technology Institute Department of Computer Engineering and Informatics University of Patras Greece Department of Applied Informatics in Administration and Economics Technological Educational Institutional of Messolongi University of Patras Greece Department of Computer Engineering and Informatics University of Patras Greece Department of Applied Informatics in Administration and Economy TEI of Messolongi Data Bases and Information Systems Sector E-business and Human Computer Interaction Lab.

The field of Statistics is a conceptually rich domain where information is complex, huge in volume, and highly valuable and critical for Governmental institutes. The daily production of statistical information increases exponentially worldwide, making the processing of all this information a very difficult and time - consuming task. Therefore, efficient search, filtering and browsing techniques are needed to access and process statistical data in an effective way. We present semantically enhanced search approach to enhance e-Govemment searching services. We evaluate our proposals on the case of Intrastat, that is the method of collecting information and producing statistics on the export and import of goods between Member States of the European Union (EU), providing added - value web search services. We employ Semantic Web technologies to create an intelligent search engine based on modeling the systems' electronic catalogue using the OWL ontology language, combined with AJAX techniques for usability richness and responsiveness. We present a search tool based on these technologies, that consists of a) our novel ontology for the EU Combined Nomenclature codes serving as a knowledge base, b)a semantically enhanced search and recommendation module that improves the quality of the results and c) a "Search as you type" visualization and navigation module to provide a usable interface to be used in navigation and search.

Networks have remained a challenge for information retrieval and visualization because of the rich set of tasks that users want to accomplish. This paper demonstrates a tool, NetLens, to explore a Content-Actor paired network data model. The NetLens interface was designed to allow users to pose a series of elementary queries and iteratively refine visual overviews and sorted lists. This enables the support of complex queries that are traditionally hard to specify in node-link visualizations. NetLens is general and scalab.e in that it applies to any dataset that can be represented with our abstract Content-Actor data model.

作者： Hutchinson, Hilary Browne Bederson, Benjamin B. Druin, Allison Human-Computer Interaction Lab. Department of Computer Science University of Maryland College Park United States Human-Computer Interaction Lab. College of Information Studies University of Maryland College Park United States

Elementary-age children (ages 6-11) are among the largest user groups of computers and the Internet, so it is important to design searching and browsing tools to support them. However, many such tools do not consider their skills and preferences. In this paper, we present the design rationale and process for creating the searching and browsing tool for the International Children's Digital Library (ICDL), the results from a user study evaluating it, and the challenges and possibilities it presents for other children's interfaces.

Color is one of the most important low-level features used in image analysis and retrieval. In this paper we introduce an algorithm for extracting compact color feature in the CIElab.color space. Our method is based on an ant colony clustering algorithm, which helps us develop a perceptually based image similarity metric. We propose a dominant color and area percentage model, which provides a very compact color feature representation of images. Besides image similarity metric is developed based on dominant colors matching. The algorithm introduced in this paper is well suited for creating small color descriptors and is efficient. It is suitable for image representation, matching and retrieval. It also has some important advantages for content-based image retrieval system, such as great reduction of the feature file sizes needed for storage and indexing.
