Quality Requirements for Multimedia Interactive Informative Systems

Abstract

<p class="MsoNormal"> <span lang="EN-US">Multimedia Interactive Informative Systems (MIIS) are software applications resulting from the convergence of multi</span><span lang="EN-US">ples technologies such as audiovisual, computing and communication. They aim to transmit information to a large, di</span><span lang="EN-US">verse and dispersed public. As with other mass media, the fulfillment of MIIS goals depends largely on the <i>quality</i> of communication between the system and end users. Therefore, those systems should be developed in order to ensure that this quality requirement is satisfied. If MIIS are constructed according to usual software engineering practices, the ana</span><span lang="EN-US">lysis discipline of the development process includes requirements identification and specification; however, these tech</span><span lang="EN-US">niques are focused on functional requirements, and they do not give much importance to non-functional requirements. In this paper, we propose a development process based on the production of videogames which has two different phases: preproduction and production. The first phase, corresponding to requirements identification, derives into the <i>concept </i>of system. In order to translate this concept into a specification, we propose the use of new communicational attributes and a MIIS metamodel. The establishment of MIIS non-functional specification is the result of analyzing class diagrams through quality attributes. In order to evaluate if the specifications are responding to communicational attributes, a functional prototype is built and evaluated with end users. The proposed methodology is applied to a real case study.</span><span lang="EN-US"><o:p></o:p></span> </p

Pierre y la Coatlicue

“…La propuesta que se fue construyendo debía entonces recoger las ideas originales del cd-rom, pero también considerar que se trataba de un material que se iba a proponer en línea. Sabíamos por experiencia que era indispensable capturar y mantener el interés del estudiante en la lengua y la cultura (Levy y Gamboa, 2013), sobre todo tratándose de un curso en línea. Con esta intención, además del uso de una estrategia narrativa que había funcionado en el caso de los cursos presenciales, se propuso utilizar una metodología inspirada en el Aprendizaje Basado en Proyectos (abp) para proponer a la comunidad estudiantil desarrollar una serie de proyectos (Cobo y Valdivia, 2017) basados en la información del sitio y en una investigación realizada en Internet, de tal manera que los resultados pudieran ser presentados y discutidos en los cursos en línea y a través de un sitio cerrado en Facebook.…”

The system of multimedia technologies implementation in high school

“…They are designed to convey information to the general public. As with other media, the achievement of goals depends largely on the quality of communication between the technology and the end users [8]. Getting the information is a voluntary decision, and the user can easily opt out of MMT with low interest.…”
