Constructional ability is a necessary part of everyday functioning for adults and children alike. In children, the need for adequate levels of constructional ability is evident during both recreational and school activities. PlayCubes is a dynamic tool that supports monitoring a variety of the perceptual-motor processes needed while children perform constructional tasks. PlayCubes is based on ActiveCube (AC), an electronic, Lego-like tangible user interface (TUI) designed to construct three-dimensional (3D) objects in both the physical and virtual realms simultaneously. In this paper we explore PlayCubes' use as a concrete, ecologically valid tool which reveals the dynamic functional processes underlying constructional ability among typically developed children. Our paper describes the PlayCubes interface including its interactive playground virtual setting, the motivation for the study, the experimental design and results to date. We conclude that, despite several technical limitations, the PlayCubes system and playground apparatus tasks appear to be sensitive to differences in children constructional abilities while presenting an engaging and enjoyable assessment tool.

Mobile imaging and digital storytelling currently support a growing practice of multimedia communication in the West. In this paper we describe a project which explores their benefit in the East, to support non-textual information sharing in an Indian village. Local audiovisual story creation and sharing activities were carried out in a one month trial, using 10 customized cameraphones and a digital library of stories represented on a village display. The findings show that the system was usable by a cross- section of the community and valued for its ability to express a mixture of development and community information in an accessible form. Lessons for the role of HC1 in this context are also discussed. Copyright 2009 ACM.

The field of relational reinforcement learning has reached its first decennium. The use of objects and relations as primary representations of states and actions introduces many new challenges and opportunities to scale the reinforcement learning paradigm to larger and more structured domains. In this paper we highlight some of the main dimensions, discuss important solution principles of both the model-based and the model-free setting, and furthermore, we briefly discuss some issues concerning domain sizes and upgrading existing propositional algorithms.

This paper presents an experimental study on environment recognition and movement control for multiagent robotic soccer using wheeled mobile robots. A color image segmentation method based on YUV color information of each pixel of the color image is applied to the object recognition. The color image segmentation is performed using the tables that transform each value in a pixel to membership in several color classes, where the lower and higher threshold values of Y, U, and V are determined and described for the sample color markers. The position of objects on the field is efficiently and accurately calculated using a monocular camera. A common image processing method is used to detect landmarks such as corners/edges in the environment. A movement control algorithm is implemented based on the distance and orientation to the target. Experimental results of real-time movement control are also presented.

Articulation training with many kinds of stimulus and messages such as visual, voice, and articulatory information can teach user to pronounce correctly and improve user's articulatory ability. In this paper, an articulation training system with intelligent interface and multimode feedbacks is proposed to improve the performance of articulation training. Clinical knowledge of speech evaluation is used to design the dependent network. Then, automatic speech recognition with dependent network is applied to identify the pronunciation errors. Besides, hierarchical Bayesian network is proposed to recognize user's emotion from speeches. With the information of pronunciation errors and user's emotional state, the articulation training sentences can be dynamically selected. Finally, a 3D facial animation is provided to teach users to pronounce a sentence by using speech, lip motion, and tongue motion. Experimental results reveal the usefulness of proposed method and system.

We examine how people's different uses of the Internet predict their later scores on a standard measure of depression, and how their existing social resources moderate these effects. In a longitudinal US survey conducted in 2001 and 2002, almost all respondents reported using the Internet for information, and entertainment and escape;these uses of the Internet had no impact on changes in respondents' level of depression. Almost all respondents also used the Internet for communicating with friends and family, and they showed lower depression scores six months later. Only about 20 percent of this sample reported using the Internet to meet new people and talk in online groups. Doing so changed their depression scores depending on their initial levels of social support. Those having high or medium levels of social support showed higher depression scores;those with low levels of social support did not experience these increases in depression. Our results suggest that individual differences in social resources and people's choices of how they use the Internet may account for the different outcomes reported in the literature.

Journal of Information and Computational science 2008年第5期5卷 2071-2076页

作者： Ji, Lianen Lu, You Zhang, Fengjun Department of Computer Science and Technology China University of Petroleum Beijing 102249 China Laboratory of Human-Computer Interaction and Intelligent Information Processing Institute of Software Chinese Academy of Sciences Beijing 100080 China

This paper presents a novel 3D interactive system for simulation and visualization of the human jaw motion. Based on the visual tracking technique, teeth plaster cast and marker cards is used for manipulating virtual teeth model and controlling the simulation of jaw motion. Through introducing their interactive semantic attributes, these physical interface elements are classified into various interaction types. Furthermore, various interaction tasks and techniques are seamlessly merged into a uniform interface framework, which integrates physical space with virtual space together. This innovative 3D interface can effectively exploit the dentist's existing skills and provide more intuitive and natural 3D interaction techniques than traditional ones. 1548-7741/Copyright © 2008 Binary Information Press October 2008.

A system for dynamic adaptation of web interfaces based on user interaction requirements

引用

11th International Conference on computers Helping People with Special Needs, ICCHP 2008

作者： Gonzalez-Pisano, Javier Rodriguez-Fernandez, Maria Gonzalez-Rodriguez, Martin Bobes-Bascaran, Jose Ramon Garcia-Marsa, Jaime Human Communication and Interaction Research Group Department of Computer Science University of Oviedo Spain

ISBN: (纸本)3540705392

This article makes the proposal for a software architecture that allows dynamic adaptation of Web interfaces depending on user interaction requirements, giving special attention to individuals who have any kind of disability. This task is achieved through several transformations on visual aspects of the Web pages such as changes on the sizes of objects, colors, relative position of the elements or navigation device used. The system separates the functionality of a Web site and its interface at runtime to customize later some of the elements of the interface according to the characteristics of the individual, taking advantage of the widespread use of Web standards such as CSS so that it is not necessary to use any additional platform for the specification of the interface. User information will be updated continuously through the use of interface autonomous agents that store data about navigation process, performing corrective actions to allow dynamic adaptation to the changing conditions of the user. © 2008 Springer-Verlag Berlin Heidelberg.

This research is part of the ongoing multinational collaboration ldquoAsian English speech corpus projectrdquo (AESOP), whose aim is to build up an Asian English speech corpus representing the varieties of English spoken in Asia. AESOP is an international consortium of linguists, speech scientists, psychologists and educators from Japan, Taiwan, Hong Kong, China, Thailand, Indonesia and Mongolia. Its primary aim is to collect and compare Asian English speech corpora from the countries listed above in order to derive a set of core properties common to all varieties of Asian English, as well as to discover features that are particular to individual varieties. Each research team will use a common recording setup and share an experimental task set, and will develop a common, open-ended annotation system. Moreover, AESOP-collected corpora will be an open resource, available to the research community at large. The initial stage of the phonetics aspect of this project will be devoted to designing spoken-language tasks which will elicit production of a large range of English segmental and suprasegmental characteristics. These data will be used to generate a catalogue of acoustic characteristics particular to individual varieties of Asian English, which will then be compared with the data collected by other AESOP members in order to determine areas of overlap between L1 and L2 English as well as differences among varieties of Asian English.
