The introduction of new materials as Power Point presentations are the most convenient way of teaching a course or to display a scientific paper. In order to support this function, most schools, universities, institutions, are equipped with projectors and computers. For controlling the presentation of the materials, the persons that are in charge with the presentation use, in most cases, both the keyboard of the computer as well as the mouse for the slides, thing that burdens, in a way, the direct communication (face to face) with the audience. Of course, the invention of the wireless mouse allowed a sort of freedom in controlling from the distance the digital materials. Although there seems to appear a certain impediment: in order to be used, the mouse requires to be placed on a flat surface. This article aims at creating a new application prototype that will manipulate, only through the means of a light-beam instrument (laser fascicle), both the actions of the mouse as well as some of the elements offered by the keyboard on a certain application or presentation. The light fascicle will be „connected” to a calculus system only through the images that were captured by a simple webcam.

The structure of today's decision support environment become very complex due to new generation of Business Intelligence applications and technologies like Data Warehouse, OLAP (On Line Analytical Processing) and Data Mining. In this respect DSS development process are not simple and needs an adequate methodology or framework able to manage different tools and platforms to achieve manager's requirements. The DSS development process must be view like a unified and iterative set of activities and operations. The new techniques based on Unified Process (UP) methodology and UML (Unified Modeling Language) it seems to be appropriate for DSS development using prototyping and RAD (Rapid Application Development) techniques. In this paper we present a conceptual framework for development and integrate Decision Support Systems using Unified Process Methodology and UML.

The status of Information and Communication Technology (ICT) as a sector characterized by a strong dynamic of development is confirmed in the strategic documents at national level in the economic field. From the scientific point of view, ICT is included in the list of research, development and innovation (RDI) sectors of smart specialization, which provide support for competitiveness and economic performance. In order to capitalize on this potential, it is important that the definition and structuring of the ICT RDI service offer to the beneficiaries of the economy to highlight the specificity and complementarity of this offer in relation to the products and services of the IT industry. The paper proposes a three-stage methodological approach for structuring such a offer: thematic focus and state-of-the-art analysis of selected topic; identifying the typology of generic solutions (characterized by a wide applicability) for the analyzed topic and creating a dedicated portfolio; establishing the categories of services that can be configured by aggregating generic solutions and prototyping them. The methodology is d exemplified in the context of a project devoted to deliver ICT RDI products and services to economical sectors of smart specialization.

The paper is aimed at depicting the ISDF software development methodology by emphasizing quality management and software development lifecycle. The ISDF methodology was built especially for innovative software development projects. The ISDF methodology was developed empirically by trial and error in the process of implementing multiple innovative projects. The research process began by analysing key concepts like innovation and software development and by settling the important dilemma of what makes a web application innovative. Innovation in software development is presented from the end-user, project owner and project manager’s point of view. The main components of a software development methodology are identified. Thus a software development methodology should account for people, roles, skills, teams, tools, techniques, processes, activities, standards, quality measuring tools, and team values. Current software development models are presented and briefly analysed. The need for a dedicated innovation oriented software development methodology is emphasized by highlighting shortcomings of current software development methodologies when tackling innovation. The ISDF methodology is presented in the context of developing an actual application. The ALHPA application is used as a case study for emphasizing the characteristics of the ISDF methodology. The development life cycle of the ISDF methodology includes research, planning, prototyping, design, development, testing, setup and maintenance. Artefacts generated by the ISDF methodology are presented. Quality is managed in the ISDF methodology by assessing compliance, usability, reliability, repeatability, availability and security. In order to properly asses each quality component a dedicated indicator is built. A template for interpreting each indicator is provided. Conclusions are formulated and new related research topics are submitted for debate.

As the cloud technologies are largely studied and mobile technologies are evolving, new di-rections for development of mobile learning tools deployed on cloud are proposed.. M-Learning is treated as part of the ubiquitous learning paradigm and is a pervasive extension of E-Learning technologies. Development of such learning tools requires specific development strategies for an effective abstracting of pedagogical principles at the software design and implementation level. Current paper explores an interdisciplinary approach for designing and development of cloud based M-Learning tools by mapping a specific development strategy used for educational programs to software prototyping strategy. In order for such instruments to be user effective from the learning outcome point of view, the evaluation process must be rigorous as we propose a metric model for expressing the trainee’s overall learning experience with evaluated levels of interactivity, content presentation and graphical user interface usability.
