ReviMobile - repositório de vídeos educacionais para m-learning utilizando agente conversacional

Abstract

The technological progress has enabled a frequent use of videos by educators in the teaching-learning process. In order to conduct this work, a study on digital video (characteristics, formats, patterns, video conversions) was made, as well as a collection of data from different repositories of digital videos available. The analysis allowed the definition of improvements to be implemented in ReviMobile, and a study on conversational agents and m-learning was also conducted. This work consists in developing a repository of videos that adapts to the technological resource, that is, to the model of mobile device being used, performing all the necessary conversions (for example, from mp4 to wmv) in a transparent and automated way. This turns out to be a viable solution to the problems of execution of videos due to different video formats and languages of development, using the process of finding a conversational agent as information recommender. Therefore, the results benefit mainly teachers and students in the process of searching and viewing educational videos; that is, showing videos in the format that is compatible with the mobile device being used in a transparent and dynamic way. This work differs in relation to other video repositories in three factors: providing mobility, adaptation to different video formats of mobile devices and conversational agent as recommender of information.
