Considering the context of Computer Science, chatbots are computer programs that use Artificial Intelligence techniques to simulate human behavior in dialogues. The use of chatbots applied to the health area has been growing, especially in scenarios for dealing with pandemics, such as COVID-19, as they help to avoid the burden of face-to-face care. Thus, this article proposes a systematic review of the work carried out in this line of research. After the review, it was found which technologies, strategies and frameworks are most used in recent times, as well as which specific areas of health are having more focus on the use of chatbots.

The aim of this work is to carry out a tertiary study on the use of Augmented Reality (AR) in education, based on a set of five research questions. This review will greatly benefit researchers who wish to conduct research on the topic for the first time. In addition, this study extends to new researchers due to the compilation of important information that was collected through Systematic Literature Reviews RSL. It was concluded that the research questions were answered based on the findings and it is also possible to observe the expansion of technologies, AR research fields and target audience by each author.
