Integração e avaliação da QoE da ferramenta openmeetings para webconferência na plataforma moodle

Abstract

The search for Distance Education through the Internet has grown in recent times, and to offer it, it is essential to use a Virtual Learning Environment (AVA). Moodle is considered the most widely used AVA in the world as an instrument in the pedagogical process in distance education and has the means that provides interactivity and communication among its users, motivating them in the learning process. In this sense, web conferencing is an excellent way to promote interaction, since it transmits images, voice, facial expressions, approaching a face-to-face classroom, and the quality of user experience (QoE) has become a factor not only in the choice of web conferencing services, but also in the definition of the way of implementing the services that enable users to be motivated to use them. Knowing about the various web conferencing tools and the importance of knowing how the user experience is using these resources, this paper aims to evaluate the user's QoE using the OpenMeetings (OM) web conferencing tool integrated in the Moodle platform in a context of Distance Education, in order to support decisions to choose such resource for integration into the virtual environment of the State University of Amazonas. In order to evaluate the use of the tool, an experimentation environment was implemented, in which the OpenMeetings platform was integrated with Moodle. In addition, a network infrastructure similar to the use of tools in production was set up, in which band control was introduced to simulate different flow scenarios. The results indicate that (i) the resources available by OM are satisfactory to educational use by users; (ii) OM allows good control of access to resources by users; (iii) QoE in relation to audio and video reception depends on available bandwidth; and in general terms the platform presents good usability and is indicated for an educational use in a production environment.
