Mobile Augmented Reality: User Interfaces, Frameworks, and Intelligence

Abstract

Mobile Augmented Reality (MAR) integrates computer-generated virtual objects with physical environments for mobile devices. MAR systems enable users to interact with MAR devices, such as smartphones and head-worn wearables, and perform seamless transitions from the physical world to a mixed world with digital entities. These MAR systems support user experiences using MAR devices to provide universal access to digital content. Over the past 20 years, several MAR systems have been developed, however, the studies and design of MAR frameworks have not yet been systematically reviewed from the perspective of user-centric design. This article presents the first effort of surveying existing MAR frameworks (count: 37) and further discuss the latest studies on MAR through a top-down approach: (1) MAR applications; (2) MAR visualisation techniques adaptive to user mobility and contexts; (3) systematic evaluation of MAR frameworks, including supported platforms and corresponding features such as tracking, feature extraction, and sensing capabilities; and (4) underlying machine learning approaches supporting intelligent operations within MAR systems. Finally, we summarise the development of emerging research fields and the current state-of-the-art, and discuss the important open challenges and possible theoretical and technical directions. This survey aims to benefit both researchers and MAR system developers alike.

LagunAR: A City-Scale Mobile Outdoor Augmented Reality Application for Heritage Dissemination

“…The field of AR has experienced a constant evolution in recent years and several surveys of AR [5,20,21] and MAR [22,23] detail the advances in the field. The goal of our project is to disseminate the historical heritage of the city of San Cristóbal de la Laguna in the XVI century using a 3D model of the city in a Location-Based MAR application (LB-MAR) [22].…”

“…Instead, it measures the angular deviation due to the movement of the user. The angle changes observed in the experiments are shown in Table 2 Sensors 2023, 23…”

Conceptual Model of Augmented Reality Mobile Application Design (ARMAD) to Enhance user Experience: An Expert Review

“…AR is a technology that substantially enhances the UX by superimposing audio or visual content [45]- [47]. In another word, AR enables mobile devices to create engaging user experiences by layering digital contents on physical environments [48], [49]. This way, AR application may captivate the user's attention through its immersive environment.…”

Meowgical AR – A Game based on Augmented Reality

“…Augmented Reality (AR) creates new immersive experiences for entertainment, games, and educational applications [1][2][3][4][5]. In recent decades AR technology has evolved and grown in popularity, it being present in more and more applications, which can be seen in the popularity of filters on social media applications (Instagram, Facebook, Snapchat), the emergence of many games that combine the fantastic with the real like Pokemon GO and in the creation of devices that can be used in everyday life, such as Project Aria 1 .…”
