Telehealth has the potential to be a valuable tool for technical and clinical support of computer controlled prosthetic devices. This pilot study examined the use of Internet-based, desktop video conferencing for remote configuration of the Otto Bock C-Leg. Laboratory tests involved connecting two computers running Microsoft NetMeeting over a local area network (IP protocol). Over 56Kbs−1, DSL/Cable, and 10Mbs−1 LAN speeds, a prosthetist remotely configured a user's C-Leg by using Application Sharing, Live Video, and Live Audio. A similar test between sites in Ottawa and Toronto, Canada was limited by the notebook computer's 28Kbs−1 modem. At the 28Kbs-1 Internet-connection speed, NetMeeting's application sharing feature was not able to update the remote Sliders window fast enough to display peak toe loads and peak knee angles. These results support the use of NetMeeting as an accessible and cost-effective tool for remote C-Leg configuration, provided that sufficient Internet data transfer speed is available.

The system of customer-oriented product cooperative design(COPCD) provides a platform for customers, on which the customer designers can participate in the cooperative design activity. Through researching on the structure of cooperative design system platform based on internet/intranet, the function, which is expressed with STEP standard file and online display via network, modified as well , in the form of product model created in Pro/E, was achieved by making use of VC++6.0 programming language and OpenGL technology. Moreover, the communication tool NetMeeting was integrated in this platform interface for the communication in the process of cooperative design activities. This system platform conceptually implements the cooperation between customer and designer, the product design efficiency and its success rate would be improved.

Data conferencing is a computing technique that helps people to communicate in realtime and to share information with others simultaneously. The T. 120 standard provides a base for: (1) multipoint data sharing; (2) interoperability; (3) reliable data transfer; (4) scalability, transparency and independence; (5) platform independence; (6) application independence. A review of the health-care data-conferencing literature identified 25 articles. Ten articles provided detailed information about data-conferencing applications. Of these, eight focused on application sharing, seven on whiteboards, two on chat and one on screen sharing. Articles published before the year 2000 typically focused on the use of NetMeeting and Intel ProShare with low-bandwidth network connections. After 2000, high-speed Internet connections became more popular and Web-based multimedia data conferencing became feasible. While there are undoubted benefits of data conferencing, more research and evaluation are required before the technique is widely implemented in health care.

Perkembangan Teknologi Informasi dan Komunikasi atau disingkat TIK yang ada saat ini ikut memberikan kontribusi dalam pengembangan bidang pendidikan khususnya di perguruan tinggi, termasuk dalam proses belajar mengajar. Proses belajar mengajar yang bersifat konvensional, dimana dosen dan mahasiswa melakukan kegiatan tatap muka di ruang kelas, sudah mulai beralih ke proses belajar jarak jauh dengan memanfaatkan TIK dalam bentuk e-learning. Dengan memanfaatkan proses e-learning ini, masalah waktu dan tempat yang biasa kita temui dapat dipecahkan, terutama pada keterbatasan ukuran kelas terhadap jumlah murid dan keterbatasan waktu untuk dapat hadir di ruang kelas. E-Learning berkembang sejalan dengan perkembangan TIK, dimana konsep E-Learning 1.0 terus mengalami perbaikan menuju ke E-Learning 2.0. Perkembangan konsep ini terutama dijumpai dalam bentuk komunikasi pada proses yang disediakan, jenis media yang digunakan dan peran dosen (Pengajar) dan mahasiswa (murid) dalam proses belajar mengajar tersebut. Deklarasi gerakan Indonesia Go Open Source atau IGOS oleh lima menteri pada tanggal 3 juni 2004 serta keharusan bagi seluruh instansi pemerintah untuk menggunakan perangkat lunak legal paling lambat Desember 2011 ikut mendorong perkembangan e-learning dengan menggunakan teknologi open source seperti Sistem Operasi Linux, Learning Management System LMS (moodle, Sakai, Dukeos), Blog (Wordpress, Joomla, Drupal), Netmeeting, Animasi dan Simulasi (Flash dan Blender). Tulisan ini akan membahas tentang pemanfaatan teknologi open source yang tersedia saat ini dalam pengembangan proses belajar jarak jauh khususnya di perguruan tinggi.

<span>This paper presents a study that illustrates how the author and an in service secondary school teacher used basic synchronous computer mediated communications (CMC) technology to help them uncover students' physics preconceptions and thought processes (including their misconceptions and misunderstandings) in a real class setting. In this paper, I first provide a discussion on constructivist science learning environments, highlighting the central role students' preconceptions play in their learning in the science subject domain. Next, I argue that in light of constructivist learning principles, learning may be viewed as a conceptual change process; a process which is facilitated by active problem solving attempts. I then present a study (which was part of a larger design experiment) whereby student pairs worked collaboratively to solve physics questions via </span><em>NetMeeting</em><span>, a free CMC software from Microsoft. Results pertaining to how protocol data of students' problem solving attempts (as recorded by </span><em>NetMeeting</em><span>) provided us with rich insights into the students' thought processes that are normally not easily accessible are discussed. Finally, I consider further research work that could be done in light of the findings of this study.</span>

The benefits in distance education of collaborative interaction via online, synchronous audio methods have been discussed in previous reports in this series. As the months go by, new software products are continually introduced to the market and existing products updated. In addition, the effect of increased traffic on the software servers is noted. The current report updates some of the series' previous reviews of online audio-conferencing products (i.e., iVisit, NetMeeting, PalTalk, and Yahoo Messenger), selected because they permit conferencing (i.e., interaction between three or more people), are free/ cost-effective, and operate on PC systems of limited capacity. These products are compared with two fully featured educational and commercial products (LearnLinc and VoiceCafé) that provide benchmarks in terms of reliability, technical features, and ease of use.

The research contained in this thesis involves three interdisciplinary dimensions: Distance Language Education (DLE) as the context of the research, videoconferencing as the technology, and the provision of oral and visual interaction in DLE as the core research problem. Though DLE is increasingly gaining importance at the start of 21st century, the inadequate provision of real-time oral-visual interaction still remains a major deficiency. To be more precise, DLE is still producing language learners who cannot speak the target language. I have outlined the urgency in solving this problem (Wang, 2004a), and it is precisely this urgency that grounds this research. This thesis therefore aims to answer the following central research question: in what ways is oral-visual interaction via videoconferencing able to facilitate L2 acquisition at a distance? In the course of answering the central research question, the following subsidiary questions are closely investigated: 1. What are the needs of distance learners in terms of L2 acquisition? 2. What are the benefits and limitations of videoconferencing-supported oral and visual interaction in the process of L2 acquisition? 3. What are the implications and potential of such interaction for L2 acquisition in distance mode? This thesis is set against a background of research on the importance of interaction in second language (L2) acquisition and the capabilities of Computer Mediated Communication (CMC). Interaction has been regarded as an integral part of communicative language learning, which promotes L2 acquisition (see Gass, 2003; Hall, 1995; Kitade, 2000; Lantolf, 1994; Mitchell & Myles, 1998; Ohta, 1995; Swain & Lapkin,1995). However, the preliminary study in this research established that, in the context of DLE, this interactive dimension has been inadequately provided, and that distance language learners do need an improved platform for L2 acquisition, especially in terms of acquiring speaking skills. The distance factor in distance language education calls for the employment of technology as a medium to provide an interactive platform for oral and visual interaction. Thus, the empirical dimension of this research, involving the participation of both on-campus and distance language learners, witnesses a two-stage evaluation of a particular Internet-based desktop videoconferencing tool, NetMeeting. In this evaluation, NetMeeting was used to conduct videoconferencing sessions, in which the teacher and participants could see and hear each other during the completion of meaning-based tasks. A great deal of original data was collected from the qualitative evaluation in regard to the benefits and limitations of videoconferencing-supported oral and visual interaction in the process of L2 acquisition in distance mode. This evaluation is approached from two aspects: the technological capabilities and pedagogical values of videoconferencing. Recommendations on the use of videoconferencing and videoconferencing task designs are proposed on the basis of the research findings. These recommendations are highly significant for practitioners in this field. Following Murray (1999), a combination of data collection methods was employed in an attempt to effectively explore the scope and depth of the participants' learning experience through videoconferencing. These methods include pre- and post-trial written surveys, in-depth post-session and post-trial interviews, videotaped videoconferencing sessions and the researcher's personal observation. Qualitative data analysis methods were adopted. Particularly important is the use of Varonis and Gass's (1985) model for analysing the negotiation routines during meaning-based task completion. The contributions of this research are manifold. Theoretically, the research updates key definitions in DLE and CMC in keeping with recent developments in each respective field. In so doing, this thesis puts forward a theory of an emerging fourth generation DLE with synchronous oral-visual interaction as its defining feature (Wang & Sun, 2001), and also proposes a new taxonomy in CMC (Wang, 2004). Both theories categorize more precisely the different roles played by different technologies and their implications for different learner goals. Empirically, this research first develops criteria for selecting appropriate videoconferencing tools (Wang & Sun, 2001) and criteria for evaluating the appropriateness of videoconferencing tasks. These two sets of criteria were then applied in the two-stage evaluation of NetMeeting, yielding useful data (Wang, 2004a; Wang, 2004b). This research also contributes to our understanding of videoconferencing task design and performance principles. The significant findings from this research confirm that Internet-based desktop videoconferencing is capable of supporting oral-visual interaction in DLE and leads to significant improvements in L2 acquisition. Most importantly, this study informs future research into the nature of oral-visual interaction enabled by videoconferencing by demonstrating how and in what ways such interaction facilitates L2 acquisition. The rapid development of computer technology makes publishing the contributions of this study an ongoing part of this research, in order to maintain the originality of this study. Some of the findings have been published in top-ranking international journals (see Wang and Sun, 2001; Wang, 2004a; Wang, 2004b). This study addresses a real and urgent need in distance language learning - the provision of oral-visual interaction. Findings from this research shed light on many issues untreated in the literature and in the practices of DLE. They also point to possible future trends in the globalisation of education because the effects of the pedagogical distance between the learner and education provider may be neutralized, or at least, minimized, through the use of CMC.

This paper details the successful and inexpensive implementation of remote laboratory experiments into a control systems course using readily available hardware and software. The custom-made experiments include an inverted pendulum, a platform leveling system, a ball and beam apparatus, and an aerodynamic beach ball levitation system, each implemented in a separate course offering. With each laboratory, the control objective is to regulate a physical parameter, (pendulum angle, platform orientation, ball position, etc.) by manipulating voltage to a drive component (DC motor, linear actuator, blower, etc.). Engineering software commonly used in controls courses (MATLAB/Simulink and LabView) coupled with dedicated hardware (xPC Target and NI Compact Rio) provide the controller platforms, while Microsoft NetMeeting and standard Internet video conferencing equipment are used to interface the distance-learning students with the laboratory equipment. Both local students at North Carolina State University’s campus in Raleigh and distance students at the University of North Carolina at Asheville and Craven Community College in Havelock, NC complete the laboratory experiments. In a student survey, distance students participating in the remote labs rated the experience as favorably as local students. Course grades, including design project grades, were similar between the two groups.
