Interactive virtual reality environments and emotions: a systematic review

Emotions influence the way people react in different contexts. Virtual reality (VR) makes it possible to generate environments that can resemble a real experience. These concepts were taken as the basis of the review, focusing on the use of VR on emotions. The search for information was carried out in the Scopus database (179) and other sources of information (17), and the selection criteria were applied to 196 results, such as the user’s interaction with the environment and the application of a software development of VR applications, resulting in the analysis of 16 studies. Unity was found to be used in 81.25% of the articles, HTC Vive appears in 37.5% of the research. The minimum time of application of the experience is 1-min contrasting with the maximum time of 30 min. Only theories of emotions were mentioned in 18.75% of the articles, most of the research uses VR to influence users (56.25%) and with the indicators only 1 article coincides with ISO 25000.
