MusA: Using Indoor Positioning and Navigation to Enhance Cultural Experiences in a museum

In recent years there has been a growing interest into the use of multimedia mobile guides in museum environments. Mobile devices have the capabilities to detect the user context and to provide pieces of information suitable to help visitors discovering and following the logical and emotional connections that develop during the visit. In this scenario, location based services (LBS) currently represent an asset, and the choice of the technology to determine users' position, combined with the definition of methods that can effectively convey information, become key issues in the design process. In this work, we present MusA (Museum Assistant), a general framework for the development of multimedia interactive guides for mobile devices. Its main feature is a vision-based indoor positioning system that allows the provision of several LBS, from way-finding to the contextualized communication of cultural contents, aimed at providing a meaningful exploration of exhibits according to visitors' personal interest and curiosity. Starting from the thorough description of the system architecture, the article presents the implementation of two mobile guides, developed to respectively address adults and children, and discusses the evaluation of the user experience and the visitors' appreciation of these application

The Exploitation of Data from Remote and Human Sensors for Environment Monitoring in the SMAT Project

In this paper, we outline the functionalities of a system that integrates and controls a fleet of Unmanned Aircraft Vehicles (UAVs). UAVs have a set of payload sensors employed for territorial surveillance, whose outputs are stored in the system and analysed by the data exploitation functions at different levels. In particular, we detail the second level data exploitation function whose aim is to improve the sensors data interpretation in the post-mission activities. It is concerned with the mosaicking of the aerial images and the cartography enrichment by human sensors—the social media users. We also describe the software architecture for the development of a mash-up (the integration of information and functionalities coming from the Web) and the possibility of using human sensors in the monitoring of the territory, a field in which, traditionally, the involved sensors were only the hardware ones.JRC.H.6-Digital Earth and Reference Dat

Planejamento para missões autônomas persistentes cooperativas de longo prazo

Orientador: Andre Ricardo FioravantiDissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de Engenharia MecânicaResumo: Uma metodologia para abordar missões autônomas persistentes a longo prazo é apresentada juntamente com uma formalização geral do problema em hipóteses simples. É derivada uma realização dessa metodologia que reduz o problema geral para subproblemas de construção de caminho e de otimização combinatória, que são tratados com heurísticas para a computação de solução viável. Quatro estudos de caso são propostos e resolvidos com esta metodologia, mostrando que é possível obter caminhos contínuos ótimos ou subótimos aceitáveis a partir de ma representação discreta e elucidando algumas propriedades de solução nesses diferentes cenários, construindo bases para futuras escolhas educadas entre o uso de métodos exatos ou heurísticosAbstract: A Methodology for tackling Persistent Long Term Autonomous Missions is presented along with a general formalization of the problem upon simple assumptions. A realization of this methodology is derived which reduces the overall problem to a path construction and a combinatorial optimization subproblems, which are treated themselves with heuristics for feasible solution computation. Four case studies are proposed and solved with this methodology, showing that it is possible to obtain optimal or acceptable suboptimal continuous paths from a discrete representation, and elucidating some solution properties in these different scenarios, building bases for future educated choices between use of exact methods over heuristicsMestradoMecanica dos Sólidos e Projeto MecanicoMestre em Engenharia Mecânica1687532CAPE
