  The purpose of this study is to present a comprehensive review of the use of
structural equation modeling (SEM) in augmented reality (AR) studies in the
context of the COVID-19 pandemic. IEEE Xplore Scopus, Wiley Online Library,
Emerald Insight, and ScienceDirect are the main five data sources for data
collection from Jan 2020 to May 2021. The results showed that a variety of
external factors were used to construct the SEM models rather than using the
parsimonious ones. The reports showed a fair balance between the direct and
indirect methods to contact participants. Despite the COVID-19 pandemic, few
publications addressed the issue of data collection and evaluation methods,
whereas video demonstrations of the augmented reality (AR) apps were utilized
