O aumento potencial da oferta de dispositivos m?veis integrados a ambientes de aprendizado m?vel permite que a informa??o saia dos ambientes f?sicos das institui??es de ensino, oportunizando a alunos e professores criarem cen?rios de aprendizagem geograficamente distribu?dos. Entretanto, muitos dos aplicativos desenvolvidos para estes ambientes ainda permanecem isolados uns dos outros e n?o se integram de maneira suficiente aos ambientes virtuais de aprendizagem (AVA). Esta disserta??o apresenta um modelo de interoperabilidade entre dispositivos m?veis e AVAs distintos baseado em webservices. Para a concep??o deste modelo, t?cnicas de engenharia de requisitos e arquitetura de software foram utilizadas. Com o intuito de mostrar a viabilidade do modelo foi desenvolvida uma aplica??o m?vel voltada para question?rios, al?m disso, as principais funcionalidades relacionadas com interoperabilidade foram testadas. / The technological evolution has been making the Distance Education accessible for a greater number of citizens anytime and anywhere. The potential increase of the supply for mobile devices integrated to mobile learning environments allows that the information comes out of the physical environment, creating opportunities for students and teachers to create geographically distributed learning scenarios. However, many applications developed for these environments remain isolated from each other and do not become integrated sufficiently into the virtual learning environments (AVA). This dissertation presents an interoperability model between mobile devices and distinct AVA based on webservices. For the conception of this model, requirements engineering and software architecture techniques were used. With the goal of showing the model viability, a mobile application focused on surveys has been developed, and additionally, the main functionalities related to the interoperability were tested
