Embedded System Architecture for Mobile Augmented Reality. Sailor Assistance Case Study

International audienceWith upcoming see-through displays new kinds of applications of Augmented Reality are emerging. However this also raises questions about the design of associated embedded systems that must be lightweight and handle object positioning, heterogeneous sensors, wireless communications as well as graphic computation. This paper studies the specific case of a promising Mobile AR processor, which is different from usual graphics applications. A complete architecture is described, designed and prototyped on FPGA. It includes hard-ware/software partitioning based on the analysis of application requirements. The specification of an original and flexible coprocessor is detailed. Choices as well as optimizations of algorithms are also described. Implementation results and performance evaluation show the relevancy of the proposed approach and demonstrate a new kind of architecture focused on object processing and optimized for the AR domain

Electronic Navigational Chart Generator for a marine mobile augmented reality system

International audienceAugmented Reality devices are about to reach mainstream markets but applications have to meet user expectations in terms of usage and ergonomics. In this paper, we present a real-life outdoor Marine Augmented Reality Navigational Assistance Application (MARNAA) that alleviates cognitive load issues (ori-entation between electronic navigational devices and bridge view) for vessels and recreational boats. First, we describe the current application and explain the requirements to draw relevant and meaningful objects. Secondly we present the 3D chart generator that extracts and provides the meaningful information to the application. Then, we detail our Marine Mobile Augmented Reality System (MMARS) and a generic architecture that can embeds MARNAA application. Finally, we present results and implementations
