Directrices para el diseño de interfaz de usuario de aplicaciones interactivas en televisión digital

Abstract

This thesis entitled "Guidelines for the designing of user interfaces of interactive applications in digital TV," is part of the project approved and funded by the Research Division of the University of Cuenca (DIUC) with the name "Application of Semantic Technologies to Reduce the Information Overload of Users of digital TV". This project considers that with the emerging of digital technology for audiovisual media, the paradigm and the way in which people watch television will change; where the high efficiency of digital coding and new transmission means will result in a significant increase in the already saturated television content offered to TV audience. Thus, is it not only necessary the emergence of intelligent tools that predicts and recommend tv programs, but the implementation of a set of graphical interfaces that allow it to manipulate and a wide range of tools that aim to improve the television experience and the way in which the TV audience communicates and interacts with the TV, not forgetting that this "new kind of TV" no longer have as a main goal to entertain and inform, but to transform the TV into a smart device adaptable to the needs of different users and conceived as an interactive device which "everybody can use". This is very feasible as long as it provides "friendly", showy and especially functional interfaces for the TV audience and not only limited to serve as a link between applications and the operating system of the digital TV platform, but to meet the viewer communication needs in an efficient and simplified manner in order to allow a more easy and intuitive contact with the TV. This document presents a relevant theoretical background, with a set of guidelines to follow during the conception, design and implementation of any interactive application interface for digital TV. This is why this analysis focuses not only on the formal representation of the preferences of viewers and TV program content using ontologies, but aims to provide guidance for the developer in the ability to build usable and accessible interactive applications while building a new communication paradigm between the viewer and the TV. A communication paradigm applicable to our technological, social and cultural context, where the use of digital technology in the media is something really new and therefore for its evaluation should be exposed to as much as possible of the Ecuadorian population without distinction of: age, social status, education level, with little or no experience managing interactive systems or any other specific distinction, to enable us to test the analysis and technology studied.
