Augmented Reality (AR) is a complex system that combines information technology into a range of fields, including health, manufacturing, education, architecture, and the gaming industry, by superimposing virtual material on the actual environment in real time. This article provides a survey of previous research on mobile augmented reality. The goal of this study is to provide a design paradigm for point-of-interest (POI) and annotation in location-based augmented reality (LBAR) mobile applications. In cultural heritage tourism, an augmented reality annotation is a note added to an AR platform with the intent of commenting on, explaining, or modifying a historical figure, item, or location. The phrase POI refers to items that capture the attention of visitors. This strategy capable of maintaining and avoiding the obliteration of cultural heritage through time. While users may enjoy an immersive experience with this augmented reality technology, researchers continue to face challenges with location accuracy and efficiency for digital material and annotations. Indoor tracking research has already been conducted utilizing a hybrid technique that combines marker-less monitoring with the sensors found on current cellphones. This article will examine how to design an augmented reality annotation for POI and how to improve the hybrid tracking approach on an outdoor platform for cultural heritage tourism, where technical challenges such as unexpected temperature and weather conditions, as well as environmental conditions, will be encountered. The outcomes of hybrid tracking approaches can improve the efficiency of augmented reality digital material while also increasing location accuracy.
