In this chapter we propose a joint exploration of Geographic Information System (GIS) and Augmented Reality (AR). Thanks to some factors, we will detail hereafter, these two domains have greatly converged in recent years further to certain factors which we shall detail hereafter. We then outline applications combining GIS and a display technique using AR in order to identify the scientific issues, as well as the functional and technical issues. Starting from this extensive state of the art of existing work, we propose a new functional classification, before concluding with different perspectives.
HAL is a multidisciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L'archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des établissements d'enseignement et de recherche français ou étrangers, des laboratoires publics ou privés.
This article presents the design and implementation of a handheld Augmented Reality (AR) system called Mobile Augmented Reality Touring System (M.A.R.T.S). The results of experiments conducted during museum visits using this system are also described. These experiments aim at studying how such a tool can transform the visitor's learning experience by comparing it to two widely used museum systems. First, we present the museum's learning experience and a related model which emerged from the state of the art. This model consists of two types of activity experienced by the observer of a work of art: sensitive and analytical. Then, we detail M.A.R.T.S architecture and implementation. Our empirical study highlights the fact that AR can direct visitors' attention by emphasizing and superimposing. Its magnifying and sensitive effects are well perceived and appreciated by visitors. The obtained results reveal that M.A.R.T.S contributes to a worthwhile learning experience.
In this paper, we propose a prototype of a (collaborative) teleassistance system for mechanical repairs based on Augmented Reality (AR). This technology is generally used to implement specific assistance applications for users, which consist of providing all the information, known as augmentations, required to perform a task. For teletransmission applications, operators are equipped with a wearable computer and a technical support expert can accurately visualize what the operator sees thanks to the teletransmission of the corresponding video stream. Within the framework of remote communication, our aim is to foster collaboration, especially informal collaboration, between the operator and the expert in order to make teleassistance easier and more efficient. To do this we rely on classical repair technologies and on collaborative systems to introduce a new human-machine interaction: the Picking Outlining Adding interaction (POA interaction). With this new interaction paradigm, technical information is provided by directly Picking, Outlining and Adding information to an item in an operator's video stream.
In this paper we shall present the T.A.C. (Télé-Assistance-Collaborative) system whose aim is to combine remote collaboration and industrial maintenance. T.A.C. enables the copresence of parties within the framework of a supervised maintenance task to be remotely "simulated" thanks to augmented reality (AR) and audio-video communication. To support such cooperation, we propose a simple way of interacting through our O.A.P. paradigm and AR goggles specially developed for the occasion. The handling of 3D items to reproduce gestures and an additional knowledge management tool (e-portfolio, feedback, etc) also enables this solution to satisfy the new needs of industry.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
