Multimedia Internet of Things: A Comprehensive Survey <s> M. AUGMENTED AND VIRTUAL REALITY IN M-IoT <s> This paper proposes a scalable Augmented Reality (AR) framework enabled by a simple extension to the Internet of Things (IoT) infrastructure, called the "ARIoT." Through ARIoT (1) potential user-proximal target objects are dynamically identified in any IoT-enabled space, (2) tracking feature information is directly obtained from the IoT objects enabling fast recognition and tracking (independent of the number of the total IoT objects everywhere), and (3) generic interactive contents are augmented as an IoT service to the AR client. To further improve the AR tracking performance, which often depends on feature appearances, this paper introduces a method in which the preferred tracking method is determined by the very IoT object in hand. The proposed concept of ARIoT is demonstrated, and its performance is evaluated and compared with the conventional single serveror client-based AR implementation. In addition, a pilot usability test is conducted between a spatially registered visual in-situ AR interface using ARIoT and a conventional interface based only on an online connection, and the results are then compared. This study shows how AR and IoT can be complementary to each other: AR as an attractive visual insitu interface for IoT objects and IoT as a basis for scalable AR1 <s> BIB001 </s> Multimedia Internet of Things: A Comprehensive Survey <s> M. AUGMENTED AND VIRTUAL REALITY IN M-IoT <s> Shipbuilding companies are upgrading their inner workings in order to create Shipyards 4.0, where the principles of Industry 4.0 are paving the way to further digitalized and optimized processes in an integrated network. Among the different Industry 4.0 technologies, this paper focuses on augmented reality, whose application in the industrial field has led to the concept of industrial augmented reality (IAR). This paper first describes the basics of IAR and then carries out a thorough analysis of the latest IAR systems for industrial and shipbuilding applications. Then, in order to build a practical IAR system for shipyard workers, the main hardware and software solutions are compared. Finally, as a conclusion after reviewing all the aspects related to IAR for shipbuilding, it proposed an IAR system architecture that combines cloudlets and fog computing, which reduce latency response and accelerate rendering tasks while offloading compute intensive tasks from the cloud. <s> BIB002 </s> Multimedia Internet of Things: A Comprehensive Survey <s> M. AUGMENTED AND VIRTUAL REALITY IN M-IoT <s> The smart city has become a new trend of interest with recent developments in information and communications technology (ICT) and the Internet of Things (IoT). These technologies provide users with new ways to interact with smart cities, especially city data. Visualizing data is crucial for improving a city's planning and management. Currently, most cases of city data visualization are mainly implemented on computers and handheld and other devices. To take advantage of augmented-reality (AR) technology, we present a method of visualizing a three-dimensional (3-D) city model of Toronto and various types of city data with the cuttingedge AR device Microsoft HoloLens. Details of our 3-D city model creation, city data extraction, geographic data processing, and user interaction design are illustrated in this article. <s> BIB003
