Augmented reality is increasingly becoming significant in people's everyday life in different sectors. Particularly to users with disabilities, augmented reality can be an instructional tool and assistive technology, making it worth a vital tool for users with disabilities. For such an important tool, it is essential to understand how these applications are evaluated in order to improve their throughput and extend their accessibility. In that regard, a systematic literature review for peer-reviewed articles published between 2012 and 2022 was conducted to discover which methods, metrics, and tools/techniques researchers use during the accessibility evaluation of augmented reality applications. The PRISMA methodology allowed us to identify, screen, and include 60 articles from three databases. The finding shows that most researchers use task scenarios as the method, qualitative feedback as the metric, and questionnaire as a tool to collect data for accessibility evaluation. The conclusion and future studies are also discussed.
