A Review of Usability Evaluation Techniques for Augmented Reality Systems in Education

Abstract

Augmented Reality (AR) converts a gigantic amount of data and analytics into images and/or animations that are overlaid into the real scene. The emerging technology of AR has been investigated for more than forty years, yet only recently, researchers have begun to formally evaluate AR applications. This paper systematically reviews the main techniques used to evaluate AR systems in educational settings for children who are less than 18 years old. Several papers have been surveyed and labelled based on their application areas. The primary contribution of this review is to present the broad landscape of usability techniques employed in AR evaluation and to provide a high-level overview of how AR systems could be tailor-made to fit the needs of children in educational environments. It further delves deeply into exploring the benefits and challenges that were noted based on these evaluations. Identifying areas where there has been an obvious disagreement in the literature is heightened, thus some opportunities for further research directions are indicated.
