Students and teachers from the municipal course PEC Continuous Education Program (PUC University SP) participated in the research during the years 2003 and 2004. A semi-structured interview was the tool used to collect data, which led to the knowledge of the students feelings concerning themselves and the teachers during the videoconference. Teachers were also interviewed and the data collected showed the feelings relating to themselves, which enabled the verification of students perception. The obtained data was analyzed according to Henri Wallon s theory as well other authors who researched the role of the videoconference in education. Feelings and emotions, which were expressed and noticed between teachers that presented the videoconferences and their female students, were verified in the results. It was also observed the unit maintenance, which means student and teacher during the teaching-learning process. Feelings such as concern, surprise, shock, satisfaction, disappointment, embarrassment, calmness, fear, dissatisfaction, discomfort, guilty, anxiety, boredom, accomplishment, tension, happiness, loneliness, depression, discouragement, annoyance and impotence were related. It has not been supported, therefore, the known belief that education through Information and Communication Technology does not provide feelings and emotions, however, time and specific preparation are needed so that female students and teachers can be proficient in this kind of learning environment / A presente dissertação teve como objetivo investigar sentimentos e emoções percebidos por alunas do PEC-Municípios durante uma videoconferência. Os participantes da pesquisa foram alunas e professores videoconferencistas do curso do PEC-Municípios, da PUC-SP, em 2003-2004. O instrumento utilizado para a coleta de dados foi a entrevista semi-estruturada, que permitiu conhecer a percepção de sentimentos das alunas no professor videoconferencista e nelas mesmas, assim como, nas entrevistas com os professores a percepção de sentimentos neles mesmos. Os dados dos professores possibilitaram a verificação da percepção das alunas. Os dados obtidos foram analisados segundo a teoria de Henri Wallon e outros autores que pesquisaram a videoconferência na educação. Nos resultados obtidos, verificamos a fluência de sentimentos e emoções expressos e percebidos entre professores(a) videoconferencistas e alunas. Da mesma forma, foi observada a manutenção da unidade aluna e professor durante o processo de ensino-aprendizagem por videoconferência. Foram relatados sentimentos como: preocupação, surpresa, susto, satisfação, frustração, constrangimento, tranqüilidade, medo, insatisfação, incômodo, culpa, ansiedade, tédio, realização, tensão, angústia, desconforto, felicidade, solidão, depressão, gelada , impotência, desânimo, ânimo. Não se manteve, portanto, a crença bastante divulgada na sociedade de que a educação e a comunicação via Tecnologia da Informação e da Comunicação são destituídas de sentimentos e emoções, ou seja, consideradas frias . No entanto, são necessários tempo e formação específica para que tanto alunas, quanto videoconferencistas se adaptem, possam se tornar proficientes neste ambiente de aprendizagem.

Sachant que les différents contextes d’interaction ont un impact sur la manière dont la conversation se déroule, le présent mémoire se concentre sur les moyens de communication à distance les plus récents : la vidéoconférence et la réalité virtuelle (VR). Nous posons la question suivante : en quoi la coordination de la conversation en réalité virtuelle est-elle différente de celle en vidéoconférence ? Pour répondre à cette question, nous poursuivons deux objectifs : (1) comparer la fréquence et la durée des silences et des chevauchements dans les différents contextes et (2) décrire les moments où il y a un bris dans la fluidité de la conversation dans chaque contexte, puis comparer ces événements entre les contextes. Nos résultats montrent que la VR n’influence pas la coordination de la conversation de la même manière que la vidéoconférence. Entre autres, les silences en VR sont plus longs et plus nombreux. De plus, les silences et les chevauchements en VR surviennent à des moments différents et ils se déroulent différemment. Les différences entre la VR et la vidéoconférence pourraient s’expliquer, entre autres, par la latence plus grande en VR, la plus grande familiarité des individus avec le contexte en vidéoconférence, les limites de la VR dans la transmission de l’information visuelle fine et le sentiment de coprésence qui se manifeste différemment dans chacun des contextes. Notre étude apporte une compréhension nuancée des interactions en vidéoconférence et en VR et souhaite encourager le développement de la recherche sur ces contextes afin d’en promouvoir une utilisation plus avisée. / We know that conversations are influenced by the context in which they take place. Therefore, this paper focuses on how conversation is managed in new forms of remote communication: videoconference and virtual reality (VR). We ask this question: how is the coordination in VR different than the coordination in videoconference? To answer this question, we pursue two objectives: (1) to compare frequency and duration of silences and overlaps between the contexts and (2) to describe what happens when the conversation flow is disturbed and then to compare those events between the contexts. Our results show that VR influences coordination between interlocutors differently than videoconference. Silences in VR are longer and happen more often than in videoconference. Moreover, silences and overlaps take place at different points in VR conversations and they unfold in a different way. The differences between VR and videoconference might be explained by the fact that there is a greater latency in VR, that participants are less familiar with the context of VR, that VR is limited in its transmission of non-verbal communication and that VR has a different effect on social presence. Our study sheds light on the importance of learning more about this new context of interaction (VR) before using it on a larger scale for interventions (e.g. with different clinical populations). Our conclusion can serve as a starting point for researchers who wish to contribute to a better understanding of the consequences of using VR as a means of communication.

This dissertation investigates videoconference technology adoption by aging-in-place organizations to facilitate the social engagement of older adults. It comprises three studies that examine the initiation and coordination of technology adoption by aging-in-place organizations and addresses the factors associated with successful adoption of relational videoconference technology by older adults. The first study is a systematic literature review exploring the role of aging-in-place organizations in social engagement of older adults through videoconference technology. The second study is a survey of adult relatives and friends of older adults regarding videoconference technology adoption by older adults during the COVID-19 pandemic and their experience with facilitating resources. It applies technology adoption theory and a structural equation model to characterize the role of aging-in-place organizations. The third study is a pilot test of a new online platform called Circular that is designed to support social engagement of older adults. Through these studies, this research extends the existing body of knowledge regarding modes to facilitate adoption of relational technology by older adults and to empower senior centers and other aging-in-place organizations as they seek to socially engage the aging members of their communities.

The increasing use of videoconferencing stimulated the creation of a new form of point-to-multipoint transmission called IP Multicast. All companies working in the area of software and the hardware development for network videoconferencing have adjusted their products as well as developed new solutionsfor the use of multicast. However the configuration of such different solutions is not easy done, moreover when changes in the operational system are also requirede. Besides, the existing free tools have limited functions, and the current comercial solutions are heavily dependent on specific platforms. Along with the maturity of IP Multicast technology and with its inclusion in all the current operational systems, the object-oriented programming languages had developed classes able to handle multicast traflic. So, with the help of Java APIs for network, data bases and hipertext, it became possible to the develop an Integrated Environment able to handle multicast traffic, which is the major objective of this work. This document describes the implementation of the above mentioned environment, which provides many functions to use and manage multicast traffic, functions which existed only in a limited way and just in few tools, normally the comercial ones. This environment is useful to different kinds of users, so that it can be used by common users, who want to join multimedia Internet sessions, as well as more advenced users such engineers and network administrators who may need to monitor and handle multicast traffic / Nas duas ?ltimas d?cadas do s?culo passado, com a consolida??o da Internet como rede mundial de computadores, aplica??es de fluxos mais robustos come?aram a surgir. A crescente uso de videoconfer?ncias impulsionou a cria??o de uma forma de transmiss?o ponto-multiponto chamada Multicast IP. Todas as empresas que desenvolviam software e hardware para videoconfer?ncia adequaram seus produtos e criaram novas solu??es para o uso do fluxo multicast. Entretanto, a configura??o das diversas solu??es n?o ? trivial e, normalmente, altera??es no sistema operacional precisam ser realizadas. Al?m disso, ferramentas gratuitas apresentam funcionalidades limitadas, e as solu??es propriet?rias encontradas na atualidade s?o muito dependentes de plataformas espec?ficas. Com o amadurecimento da tecnologia Multicast IP e com sua inclus?o em todos os sistemas operacionais atuais, as linguagens de programa??o desenvolveram classes capazes de manipular tr?fego multicast. Com as APIs Java para redes, banco de dados e p?ginas Web, tornou-se poss?vel a cria??o de um Ambiente Integrado capaz de manipular tr?fego multicast, que se constitui na proposta central deste trabalho. Esse documento descreve ent?o a implementa??o deste ambiente que agrega diversas funcionalidades para utiliza??o e ger?ncia de tr?fego multicast, funcionalidades at? ent?o presentes de forma limitada em poucas e distintas ferramentas comummente propriet?rias. O ambiente se adequa a diferentes perfis de usu?rio, no sentido de que pode ser usado por leigos em Engenharia de Redes, que desejem apenas participar de sess?es de multim?dia na Internet, como tamb?m por especialistas e administradores de rede que desejem monitorar e manipular o tr?fego multicast

Ce travail s’intéresse aux rencontres interculturelles franco-allemandes, dans le cadre de l’apprentissage du français langue étrangère du voisin, avec vidéoconférence de groupe. Dans une perspective conversationnaliste (Goffman, Traverso, Cicurel), nous envisageons la conversation comme activité sociale et didactique, en posant l’hypothèse que la conversation ordinaire favorise la rencontre interculturelle en classe de langue. Nous menons une analyse conversationnelle, non verbale et verbale, à partir d’un corpus constitué de l’enregistrement vidéoscopique d’une conversation par vidéoconférence entre une classe de français langue étrangère à l’Université de Hanovre et un groupe d’étudiants de la langue-cible, ne parlant pas allemand, situé dans une université française. Nous partons du schéma de la conversation familière pour conduire une analyse qui nous amène à le remodeler et à proposer un schéma de la rencontre interculturelle franco-allemande en classe de langue. / This research on French-German intercultural encounters, within the framework of learning French as a neighbouring foreign language, has been carried out using group-based videoconference. Using a conversationalist approach (Goffman, Traverso, Cicurel), we consider conversation as both a social and a didactic activity; our hypothesis is that ordinary conversation promotes intercultural encounters in the classroom. We have carried out both a non-verbal and a verbal conversation analysis of a corpus made from a video-recorded conversation during a videoconference. The students were in a French (as a foreign language) class at the University of Hanover, and met a group of students (of the target language) who were in a French university did not speak any German. We based our analysis on the familiar conversation scheme in order to reshape it and to suggest a scheme for French-German intercultural encounters in the classroom.

This applied dissertation is an instrumental case study based on diffusion of innovations theory designed to gather student opinions regarding videoconference (VC) technology use in facilitating courses to undergraduate degree-seeking nursing students. The author of diffusion of innovations theory, Rogers (2003), recommended that more qualitative studies be conducted in education. Rogers and Jain (1968) recommended these studies should be conducted from the aspect of “receivers of innovation diffusion” (p.1) to provide feedback instrumental to implementation of technological innovations in academe. Further, Rogers stated that multiple data points should be used during the process of trialing an innovation. Therefore, a current VC course was selected from the nursing curriculum of a public state college hosting one of the largest nursing programs in the southeastern United States in which to conduct the study. A total of 32 students participated divided equally between two sites: Main campus and Regional campus. Further divided, 22 personal interviews were conducted and two focus groups; one for each campus consisting 5 students each. Additionally, included in the data corpus were 40 hours of classroom observation plus, college provided end of course (EOC) summary statements. These data were triangulated to determine whether students would accept VC technology unchanged, accept with modifications, or reject VC technology based on first time exposure to the innovation during the 16-week semester. Student innovation decisions were: 6 students accepted unchanged, 14 students accepted with modifications, and 12 students rejected the innovation. Students who rejected the innovation were exclusively from the regional campus, which was the receiving site the majority of the semester. First and second-cycle analyses yielded 67 codes resulting in 5 categories, which further developed into 3 emerging themes: (a) Interaction with instructors, materials, and distant students are key elements affecting adoption decisions of students regarding VC technology; (b) Student adoption decisions are influenced by faculty members in their use of VC technology; and (c) Student opinions indicate that reinvention is necessary for VC technology to be fully adopted into the present nursing program. The five categories: Interaction, equipment, teaching methodology, instructor technology training, and student orientation provided ample detail from which to inform practice regarding recommendations for reinvention (modification) of VC technology during the implementation stage of Rogers’ five stages of the innovation-decision model. These modifications could assist the college in gaining parity between the two nursing sites, which reported an 18.53 percentage point difference in first time pass rates on the NCLEX-RN exam reported by the Florida Department of Health (Florida Health, 2015).

Este trabalho apresenta um sistema de conferência multiponto centralizada com controle de posse da palavra, que oferece comunicação por voz e por texto, desenvolvido para dar suporte a ferramentas de educação a distância baseadas em tecnologia web. Além do sistema de conferência multiponto, este trabalho introduz, também, conceitos de voz sobre IP (VoIP), codecs de áudio, tráfego de tempo real sobre redes IP, mecanismos de distribuição de pacotes em redes IP, conferências multimídia sobre redes IP, criação e controle de conferências e mecanismos para se controlar a transmissão de pacotes de voz em conferências multiponto, como detecção de atividade de voz (VAD) e controle de posse da palavra. O controle de posse da palavra ou moderação é uma metodologia para coordenar o acesso a recursos de mídia contínua, como os canais de áudio e vídeo em conferências, resolvendo eventuais conflitos e condições de corrida e garantindo o uso exclusivo dos mesmos por um participante da conferência. O controle de posse da palavra é apropriado para a dinâmica de uma sala de aula, onde na maioria das vezes, o professor exerce o papel de um moderador e de principal interlocutor. Além de regular o fluxo de informação na sala de aula virtual, o controle de posse da palavra também ajuda a reduzir a utilização dos recursos da rede. Como principal resultado deste trabalho, uma arquitetura para o sistema de conferência multiponto foi proposta, implementada e testada. Verificou-se que o sistema é escalável e que o controle de posse da palavra reduz o grau de interatividade entre os participantes da conferência, mas funciona eficazmente como mecanismo para reduzir a utilização dos recursos de rede. A comunicação adicional por texto ajuda a reduzir o impacto do controle de posse da palavra no grau de interatividade. Neste trabalho, o uso de uma topologia centralizada para a realização de conferências multiponto mostrou-se bastante vantajoso, principalmente porque o tráfego multicast não era suportado. / This work presents a centralized multipoint conference system with floor control, which offers voice and text communication capability, developed to support distance learning tools based on web technology. This work also brings concepts about voice over IP (VoIP), audio codecs, real-time traffic over IP networks, packet distribution mechanisms in IP networks, multimedia conferences over IP networks, establishment and control of conferences and mechanisms to control voice packets transmission in multipoint conferences, as Voice Activity Detection (VAD) and floor control. Floor control is a suitable methodology for coordinating access to continuous media resources, such as audio and video channels in conferences, solving resource conflicts and race conditions and guaranteeing their mutually exclusive use by one participant of the conference. Floor control is appropriate for the classroom’s dynamics, where the teacher, mostly, has the role of a moderator and main talker. Besides regulating the information flow in the virtual classroom, floor control helps reducing the need for network resources. As main result, an architecture for the multipoint conference system was proposed, implemented and tested. It was found that the system is scalable and that floor control reduces the interactivity among the conference’s participants, but works efficiently as a mechanism for reducing the need for network resources. Text communications help lowering the impact of floor control on interactivity. In this work, the deployment of a centralized topology for multipoint conferences showed to be very advantageous, mainly because multicast traffic was not supported.
