TL;DR: This paper describes how streaming data can be stored in a scalable and flexible document schema based database such as MongoDB, a data store that makes up the virtual twin system that results in the virtualization of a machine resource to external factory manufacturing systems.

08 Jun 2004TL;DR: The ability to reconstruct a full-body model of the actors and any additional props or elements opens the way for very natural interaction techniques using the entire body and real elements manipulated by the user, whose avatar is immersed in a virtual world.
Abstract: Real-time video acquisition is becoming a reality with the most recent camera technology. Three-dimensional models can be reconstructed from multiple views using visual hull carving techniques. However the combination of these approaches to obtain a moving 3D model from simultaneous video captures remains a technological challenge. In this paper we demonstrate a complete system architecture allowing the real-time (≤ 30 fps) acquisition and full-body reconstruction of one or several actors, which can then be integrated in a virtual environment. A volume of approximately 2m3 is observed with (at least) four video cameras and the video fluxes are processed to obtain a volumetric model of the moving actors. The reconstruction process uses a mixture of pipelined and parallel processing, using N individual PCs for N cameras and a central computer for integration, reconstruction and display. A surface description is obtained using a marching cubes algorithm. We discuss the overall architecture choices, with particular emphasis on the real-time constraint and latency issues, and demonstrate that a software synchronization of the video fluxes is both sufficient and efficient. The ability to reconstruct a full-body model of the actors and any additional props or elements opens the way for very natural interaction techniques using the entire body and real elements manipulated by the user, whose avatar is immersed in a virtual world.

TL;DR: This paper describes a new architecture improvement method called APTIA (Analytic Principles and Tools for the Improvement of Architectures), which almost entirely reuses pre-existing techniques but in a new combination, with new goals and results.

TL;DR: In this article, the authors present a system architecture and an implemented system, FRAMER, that demonstrate the cooperative problem solving approach to demonstrate design knowledge in formal, machine-interpretable knowledge sources such as critics and dynamic specification sheets, and in semi-formal knowledge source such as a palette of user interface building blocks and a checklist.
Abstract: Designing a user interface is an ill-defined problem making cooperative problem solving systems a promising approach to support user interface designers. Cooperative problem solving systems are modular systems that support the human designer with multiple, independent system components. We present a system architecture and an implemented system, FRAMER, that demonstrate the cooperative problem solving approach. FRAMER represents design knowledge in formal, machine-interpretable knowledge sources such as critics and dynamic specification sheets, and in semi-formal knowledge sources such as a palette of user interface building blocks and a checklist. Each of these components contributes significantly to the overall usefulness of the system while requiring only limited resources to be designed and implemented. ’

13 Jun 2005TL;DR: This position paper will propose a set of elements, information and graphical notation to record the design decisions during the modelling process, to detail the idea of considering the architecture as a composition of architectural design decisions.
Abstract: Documenting software architectures is a key aspect to achieve success when communicating the architecture to different stakeholders. Several architectural views have been used with different purposes during the design process. The traditional view on software architecture defines this in terms of components and connectors. Also, the “4+1” view model proposes several views from the same design to satisfy the interests of the different stakeholders involved in the modelling process. In this position paper we try to go a step beyond previous proposals, to detail the idea of considering the architecture as a composition of architectural design decisions. We will propose a set of elements, information and graphical notation to record the design decisions during the modelling process.
