Augmented reality has an important role as an engine for the development and improvement of tools for the educational sector through the use of mobile devices, creating new environments within the classroom. This research is carried out in order to investigate trends in augmented reality applications in learning through mobile devices. A bibliometric analysis is implemented as a methodology that includes 111 scientific papers, where indicators of productivity, quality, structure and thematic trends were raised and analyzed. There is evidence of the growing interest in research in the field in general, mainly addressing the topics of learning systems, mobile augmented reality and mobile devices. It is concluded that the applications of new technologies provide better results in learning processes and more meaningful experiences, by involving students directly, giving them autonomy and teaching them in more dynamic and interactive contexts.
