As a robot formation increases in size or explores places where it is difficult for a human operator to interact, autonomous control becomes critical. We propose a distributed autonomous method for evaluating properties of multi-robot systems, and then discuss how this information can be applied to improve performance with respect to a given operation. We present this as an extension of our previous work on robot formations;however, the techniques described could be adapted to other multi-robot systems.

This study presents an analysis of the effect of different graph types on the comprehension of cyclic events. The results indicated that although round and linear graph designs are informationally equivalent, the round graphs are computationally better suited than linear graphs for the interpretation of cyclic concepts. © Springer-Verlag Berlin Heidelberg 2010.

This symposium addresses how different classes of research methods, all based upon the use of log data from educational software, can facilitate the analysis of students' learning strategies and behaviors. To this end, four multi-method programs of research are discussed, including the use of qualitative, quantitative-statistical, quantitative-modeling, and educational data mining methods. The symposium presents evidence regarding the applicability of each type of method to research questions of different grain sizes, and provides several examples of how these methods can be used in concert to facilitate our understanding of learning processes, learning strategies, and behaviors related to motivation, meta-cognition, and engagement. © ISLS.

Working Conference on Reverse Engineering

Plug-in architectures enable developers to build extensible software products. Such products are assembled from plug-ins, and their functionality can be enriched by adding or configuring plug-ins. The plug-ins themselves consist also of multiple plug-ins, and offer dedicated points through which their functionality can be influenced. A well-known example of such an architecture is Eclipse, best known for its use to create a series of extensible IDEs. In order to test systems built from plug-ins developers use extensive automated test suites. Unfortunately, current testing tools offer little insight in which of the many possible combinations of plug-ins and plug-in configurations are actually tested. To remedy this problem, we propose three architectural views that provide an extensibility perspective on plug-in-based systems and their test suites. The views combine static and dynamic information on plug-in dependencies, extension initialization, and extension usage. The views are implemented in ETSE, the Eclipse Plug-in Test Suite Exploration tool. We evaluate the proposed views by analyzing eGit and Mylyn, two open source Eclipse plug-ins.

We examine the design space of interaction techniques for very large wall displays by drawing from existing theory and practice for reality-based interfaces and whole-body interfaces. We also apply insights drawn from research in psychology about the human cognitive mechanisms that support sensorimotor operations in different coordinate spaces, as well as research in sociology examining how people manage coordination and privacy concerns in these spaces. Using guidelines obtained from these analyses, we designed and implemented a novel suite of body-centric interaction techniques. These were integrated into a map browsing and editing application for a very large (5m×3m) wall display. The application was then used to gather user feedback to guide the further development of the interaction techniques. © 2010 ACM.

Despite intense research activities in the last years, HCI patterns still lack in a standardized description and organization. This makes it difficult for the developers to identify the relevant patterns for solving a problem as well as to apply them accordingly to the problem context. To fully benefit from HCI patterns within the engineering of interactive computer systems they have to be prepared for integration into a model-based user interface development process. This workshop on Pattern-driven Engineering of Interactive computer Systems (PEICS) focuses on bringing together various research approaches in order to be conjointly conductive to the state of the art. We present contributions according to semantics, formalization, languages, support, research directions as well as tools. © 2010 ACM.

The elderly represent a valid group of users who can potentially benefit greatly from engaging with technology, such as healthcare systems or playing digital games. Yet, less attention has been given to the significance of senior citizens as technology users, as compared to the common younger population. In an effort to fill in the gap, this workshop aims to investigate the design of technology for senior citizens. To provide for more focused, thus more productive discussion, we will use elderly mobile phone games as a case in point here. The overarching objective is to understand what can help to make for better and more meaningful use of interactive applications and technology by the elderly, for instance, games on the mobile phone. © 2010 Copyright is held by the author/owner(s).

Understanding Individual Nodes in Peer-to-Peer Systems

Understanding Individual Nodes in Peer-to-Peer Systems

International Conference on computer Communications and Networks (ICCCN)

作者： Gyuwon Song Suhyun Kim Sunghwan Jang Daeil Seo Human Computer Interaction and Robotics Department University of Science and Technology Seoul South Korea Imaging Media Center Korea Institute of Science and Technology Seoul South Korea

This paper addresses a simple question: Is there a behavior pattern of an individual node in peer-to-peer systems? It is known that peer-to-peer systems collectively show daily patterns, but the behavior patterns of individual nodes have seldom been studied. If individual nodes have their own behavior patterns with reasonable accuracy, we could greatly improve the efficiency of the system by reducing the overhead to handle unexpected random node failures. Even though there have been many empirical studies on peerto-peer systems, most of them are focusing on a collective view to characterize the whole systems in terms of average availability, average session length, and so on. In this paper we present Peer Availability Table (PAT) which is a model to represent a behavior pattern of an individual node based on the measurement of node availability. To judge the existence of the behavior pattern, we measure the performance of PAT using a binary classification test. By answering the basic question, we provide a useful hint for the design of peer-to-peer systems.

From keyword search to exploration: Designing future search interfaces for the web

This monograph is directed at researchers and developers who are designing the next generation of web search user interfaces, by focusing on the techniques and visualizations that allow users to interact with and have control over their findings. Search is one of the keys to the Web's success. The elegant way in which search results are returned has been well researched and is usually remarkably effective. However, the body of work produced by decades of research into information retrieval continues to grow rapidly and so it has become hard to synthesize the current state-of-the-art to produce a search interface that is both highly functional, but not cluttered and distracting. Further, recent work has shown that there is substantial room for improving the support provided to users who are exhibiting more exploratory forms of search, including when users may need to learn, discover, and understand novel or complex topics. Overall, there is a recognized need for search systems to provide effective user experiences that do more than simply return results. With the aim of producing more effective search interfaces, human computer interaction researchers and web designers have been developing novel interactions and features that enable users to conveniently visualize, parse, manipulate, and organize their Web search results. For instance, while a simple set of results may produce specific information (e.g., the capital of Peru), other methods may let users see and explore the contexts of their requests for information (more about the country, city, and nearby attractions), or the properties that associate groups of information assets (grouping hotels, restaurants, and attractions by their type, district, or price). Other techniques support information-seeking processes that may last weeks or months or may even require collaboration between multiple searchers. The choice of relevant result visualization strategies in new search systems should reflect the searchers and th

Many people do not read easily. They may have an impairment such as a visual problem. They may be reading in stressful conditions or poor light, or perhaps they are reading in a second language. Is it possible to provide one consistent set of guidelines or approaches that will allow designers of electronic materials to meet all the apparently diverse needs of these people? Or are there compromises to be made? If so, what are those compromises? © 2010 Copyright is held by the author/owner(s).
