Arquitetura e cliente para gravação de áudios de aulas por meio de dispositivos de internet das coisas.

Abstract

It is proposed in this work, a computer system that uses internet of things devices as a tool to support teachers and students, performing the recording of classroom audios, recording of notes and automatic upload of these resources. A service-oriented architecture is used through a REST API that ensures interoperability between heterogeneous devices and provides the necessary services for the Web client and the recording client, Raspberry Pi, as well as a redundant database architecture with MongoDB. It is expected, with the proposed system, the process of review and elucidation of students doubts will be facilitated, through the reproduction of the recorded audios and the consultation to the annotations of the class, in a moment after the lesson. This expectation is validated by the application of questionnaires to students of the course of Computing Engineering of Universidade Estadual do Maranhão, after contact with the developed prototype, and the results obtained are brought in this work.
