By the Natural User Interfaces (NUI), interactive processes such as touch and gesture-based became more present in applications of several domains with an ever-increasing demand of varied resource sharing. With this potential in mind, the local or remote collaborative task accomplishment become imminent. The present work aims to present the development of an application for multimedia content sharing and visualization between physically detached and heterogeneous devices adopting the interaction technique named drag-and-drop.

The produced data by the sensors generally combined with information provided by webservices are used as reference for the information provisioning for such applications, which if poorly specified conduct to an interface cluttering and the degradation of the interactive process. Hence, this work aims to present a proposal of standardization of mobile navigation applications by the creation of a representation model for the displayed information, allowing a richer and customizable on-thefly experience in Augmented Reality Browsers (ARB). First of all, it is presented a general architecture for the information transferring between AR browsers and a provider structure. Later, it is discussed the structure and conception of the representation model, responsible for the identifying and filter the relevant information to users.

Such fusion occurs by the implementation of Loader classes, capable to import the resulting models of the reconstruction process and to prepare them to the VR resources treatment, such as visualization and manipulation techniques.

This information can be provided by heterogeneous databases that may not be considered relevant by most systems, e.g., social media data, blogs and more. If organizations would use such sources, they could build a new management vision known as Competitive Intelligence. In the context of architectures of Information Retrieval, this research aims on implementing a semantic extraction agent for the Web environment, allowing information finding, storage, processing and retrieval, such as those from the Big Data context produced by several informational sources on the Internet, serving as a basis for the implementation of information environments for decision support. Using this method, it will be possible to verify that the agent and ontology proposal addresses this part and can play the role of a semantic level of the architecture.

Tangible User Interface (TUI) is an exemple of such interfaces. With TUI, physical objects can be linked to digital information providing a more powerful interaction experience to users. While actual TUI modelling approaches facilitate the integration of physical objects in TUI interfaces, none of them associates high level semantics to those objects. In this paper a model-based methodology is proposed to accomplish the design process of advanced tangible user interfaces. The uniqueness of the proposed approach is to be platform independent, focusing on the interface elements and their behavior, and how they can be used to reach the user's goals. A case study of an interactive management system interface for unmanned flight is used to validate the proposed model.
