Developing a Pedagogical Framework for Designing a Multisensory Serious Gaming Environment

The importance of multisensory interaction for learning has increased with improved understanding of children’s sensory development, and a flourishing interest in embodied cognition. The potential to foster new forms of multisensory interaction through various sensor, mobile and haptic technologies is promising in providing new ways for young children to engage with key mathematical concepts. However, designing effective learning environments for real world classrooms is challenging, and requires a pedagogically, rather than technologically, driven approach to design. This paper describes initial work underpinning the development of a pedagogical framework, intended to inform the design of a multisensory serious gaming environment. It identifies the theoretical basis of the framework, illustrates how this informs teaching strategies, and outlines key technology research driven perspectives and considerations important for informing design. An initial table mapping mathematical concepts to design, a framework of considerations for design, and a process model of how the framework will continue to be developed across the design process are provided

An MDE-based framework to support the development of Mixed Interactive Systems

International audienceIn the domain of Human Computer Interaction (HCI), recent advances in sensors, communication technologies, miniaturization and computing capabilities have led to new and advanced forms of interaction. Among them, Mixed Interactive Systems (MIS), form a class of interactive systems that comprises augmented reality, tangible interfaces and ambient computing; MIS aim to take advantage of physical and digital worlds to promote a more transparent integration of interactive systems with the user's environment. Due to the constant change of technologies and the multiplicity of these interaction forms, specific development approaches have been developed. As a result, numerous taxonomies, frameworks, API and models have emerged, each one covering a specific and limited aspect of the development of MIS. To support a coherent use of these multiple development resources and contribute to the increasing popularity of MIS, we have developed a framework based on Model-Driven Engineering. The goal is to take advantage of Model-Driven Engineering (MDE) standards, methodology and tools to support the manipulation of complementary Domain Specific Languages (DSL), to organize and link the use of different design and implementation resources, and to ensure a rationalized implementation based on design choices. In this paper, we first summarize existing uses of MDE in HCI before focusing on five major benefits MDE can provide in a MIS development context. We then detail which MDE tools and resources support these benefits and thus form the pillars of the success of an MDE-based MIS development approach. Based on this analysis, we introduce our framework, called Guide-Me, and illustrate its use through a case study. This framework includes two design models. Model transformations are also included to link one model to another; as a result the frameworks coverage extends from the earliest design step to a software component-based prototyping platform. A toolset based on Eclipse Modeling Framework (EMF) that supports the use of the framework is also presented. We finally assess our MDE-based development process for MIS based on the five major MDE benefits for MIS

A cooperative-relational approach to digital libraries

Copyright @ 2007 Springer-Verlag, Berlin HeidelbergThis paper presents a novel approach to model-driven development of Digital Library (DL) systems. The overall idea is to allow Digital Library systems designers (e.g. information architects, librarians, domain experts) to easily design such systems by using a visual language. We designed a Domain Specific Visual Language for such a purpose and developed a framework supporting it; this framework helps designers by automatically generating code for the defined Digital Library system, so that they do not have to get involved into technical issues concerning its deployment. In our approach, both Human-Computer Interaction and Computer Supported Collaborative Work techniques are exploited when generating interfaces and services for the specific Digital Library domain

Applying a model-based methodology to develop web-based systems of systems

Systems of Systems (SoS) are emerging applications composed by subsystems that interacts in a distributed and heterogeneous environment. Web-based technologies are a current trend to achieve SoS user interaction. Model Driven Web Engineering (MDWE) is the application of Model Driven Engineering (MDE) into the Web development domain. This paper presents a MDWE methodology to include Web-based interaction into SoS development. It's composed of ten models and seven model transformations and it's fully implemented in a support tool for its usage in practice. Quality aspects covered through the traceability from the requirements to the nal code are exposed. The feasibility of the approach is validated by its application into a real-world project. A preliminary analysis of potential benets (reduction of eort, time, cost; improve of quality; design vs code ratio, etc) is done by comparison to other project as an initial hypothesis for a future planned experimentation research.Ministerio de Economía, Industria y Competitividad TIN2013-46928-C3- 3-RMinisterio de Economía, Industria y Competitividad TIN2015-71938-RED

Research on Application of Cognitive-Driven Human-Computer Interaction

Human-computer interaction is an important research content of intelligent manufacturing human factor engineering. Natural human-computer interaction conforms to the cognition of users' habits and can efficiently process inaccurate information interaction, thus improving user experience and reducing cognitive load. Through the analysis of the information interaction process, user interaction experience cognition and human-computer interaction principles in the human-computer interaction system, a cognitive-driven human-computer interaction information transmission model is established. Investigate the main interaction modes in the current human-computer interaction system, and discuss its application status, technical requirements and problems. This paper discusses the analysis and evaluation methods of interaction modes in human-computer system from three levels of subjective evaluation, physiological measurement and mathematical method evaluation, so as to promote the understanding of inaccurate information to achieve the effect of interaction self-adaptation and guide the design and optimization of human-computer interaction system. According to the development status of human-computer interaction in intelligent environment, the research hotspots, problems and development trends of human-computer interaction are put forward

NASTRAN data generation of helicopter fuselages using interactive graphics

The development and implementation of a preprocessor system for the finite element analysis of helicopter fuselages is described. The system utilizes interactive graphics for the generation, display, and editing of NASTRAN data for fuselage models. It is operated from an IBM 2250 cathode ray tube (CRT) console driven by an IBM 370/145 computer. Real time interaction plus automatic data generation reduces the nominal 6 to 10 week time for manual generation and checking of data to a few days. The interactive graphics system consists of a series of satellite programs operated from a central NASTRAN Systems Monitor. Fuselage structural models including the outer shell and internal structure may be rapidly generated. All numbering systems are automatically assigned. Hard copy plots of the model labeled with GRID or elements ID's are also available. General purpose programs for displaying and editing NASTRAN data are included in the system. Utilization of the NASTRAN interactive graphics system has made possible the multiple finite element analysis of complex helicopter fuselage structures within design schedules

Extending ASSERT for HW/SW Co-design

Embedded systems are commonly designed by specifying and developing hardware and software systems separately. On the contrary, the hardware/software (HW/SW) co-development exploits the trade-offs between hardware and software in a system through their concurrent design. HW/SW Codevelopment techniques take advantage of the flexibility of system design to create architectures that can meet stringent performance requirements with a shorter design cycle. This paper presents the work done within the scope of ESA HWSWCO (Hardware-Software Co-design) study. The main objective of this study has been to address the HW/SW co-design phase to integrate this engineering task as part of the ASSERT process (refer to [1]) and compatible with the existing ASSERT approach, process and tool, Advances in the automation of the design of HW and SW and the adoption of the Model Driven Architecture (MDA) [9] paradigm make possible the definition of a proper integration substrate and enables the continuous interaction of the HW and SW design paths

25 Years of Model-Driven Web Engineering : What we achieved, what is missing

Model-Driven Web Engineering (MDWE) approaches aim to improve the Web applications development process by focusing on modeling instead of coding, and deriving the running application by transformations from conceptual models to code. The emergence of the Interaction Flow Modeling Language (IFML) has been an important milestone in the evolution of Web modeling languages, indicating not only the maturity of the field but also a final convergence of languages. In this paper we explain the evolution of modeling and design approaches since the early years (the 90’s) detailing the forces which drove that evolution and discussing the strengths and weaknesses of some of those approaches. A brief presentation of IFML is accompanied with a thorough analysis of the most important achievements of the MDWE community as well as the problems and obstacles that hinder the dissemination of model-driven techniques in the Web engineering field.Laboratorio de Investigación y Formación en Informática Avanzada (LIFIA

Modeling magnetized star-planet interactions: boundary conditions effects

Conference ProceedingCopyright © International Astronomical Union 2013We model the magnetized interaction between a star and a close-in planet (SPMIs), using global, magnetohydrodynamic numerical simulations. In this proceedings, we study the effects of the numerical boundary conditions at the stellar surface, where the stellar wind is driven, and in the planetary interior. We show that is it possible to design boundary conditions that are adequate to obtain physically realistic, steady-state solutions for cases with both magnetized and unmagnetized planets. This encourages further development of numerical studies, in order to better constrain and undersand SPMIs, as well as their effects on the star-planet rotational evolution. © 2013 International Astronomical Union
