In this scope, optical seethrough head-mounted displays (OST-HMDs) are particularly interesting as they typically use an additive light model, which denotes that the perception of the displayed virtual imagery is a composite of the lighting conditions of one's environment, the coloration of the objects that make up the virtual imagery, and the coloration of physical objects that lay behind them. While a large body of literature focused on investigating the visual perception of UI elements in immersive and flat panel displays, comparatively less effort has been spent on OST-HMDs. Due to the unique visual effects with OST-HMDs, we believe that it is important to review the field to understand the perceptual challenges, research trends, and future directions. In this paper, we present a systematic survey of literature based on the IEEE and ACM digital libraries, which explores users' perception of displaying text-based information on an OST-HMD, and aim to provide relevant design suggestions based on the meta-analysis results. We carefully review 14 key papers relevant to the visual perception research in OST-HMDs with UI elements, and present the current state of the research field, associated trends, noticeable research gaps in the literature, and recommendations for potential future research in this domain.Human centered computingMixed / augmented realityGeneral and referenceSurveys and overviews10.2312/egve.2020125627-35
