Ítem BDNG: A dublin core-based architecture for digital libraries(2005-01-01) Montoya, E.; Ruiz, M.; Giraldo, J.; Universidad EAFIT. Departamento de Ingeniería de Sistemas; I+D+I en Tecnologías de la Información y las ComunicacionesDigital Libraries will be one of the main ways to access structured information through the Internet. Information related to resources or objects is known as metadata. Several metadata models have been proposed; however, the model proposed by the Dublin Core Metadata Initiative (DCMI) [1] has demonstrated great utility in digital libraries. The simplicity and generality of DCMI has facilitated the deployment of digital libraries and their interoperability. This paper proposes DCMI as metadata model in our own Digital Library Architecture (Biblioteca Digital de Nueva Generación -BDNG). We have extended DCMI and used some elements of DC-Library application profile (DC-Lib) [2] in addition to new elements not previously considered. This paper presents the metadata models for the following applications: digital library of EAFIT University (BDEeafit), integration of digital or referential libraries (BDMetaLib) and digital library for E-Learning systems (BDEI). This paper also describes the general architecture of BDNG.Ítem Design and usability evaluation of a multi-input interface in an idTV environment(Springer Verlag, 2017-01-01) Téllez J.F.; Montoya J.C.; Trefftz H.; Universidad EAFIT. Departamento de Ingeniería de Sistemas; I+D+I en Tecnologías de la Información y las ComunicacionesIn recent years, and considering the rise of Interactive Digital Television (idTV), it has been great interest in the design of applications and services for this platform. However, the success of these applications largely depends on the ease of use and how users interact with them. For this reason, we have explored different interfaces and modes of interaction to improve the user experience with these applications in comparison with the traditional Remote-Control (RC). This article presents an interaction with idTV applications using multiple input control interfaces with different modes of interaction such as touch buttons, gesture recognition, voice recognition, and recognition of movements. These modes of interaction were validated through usability testing using a model of quasi-experimental evaluation of three dimensions, where each dimension represents respectively: users, tasks and control interfaces. As a result of the qualitative and quantitative assessments, we performed an analysis of possible improvements in the usability of a particular application of idTV. The results showed few differences between one multi-input control interface and one RC in tasks the user was familiar with, on the opposite, significant differences were found in performing tasks involving greater user interaction, such as the text input or navigation between menus. © Springer International Publishing AG 2017.Ítem Diseño de un modelo de negocio metamediario para el sector ferretero y sus actores asociados en Bogotá(Universidad EAFIT, 2024) Triana Clavijo, Wilmar Eduardo; Amador Poveda, María Ximena; Acevedo Mejía, Erika Cristina; Jiménez Bustamante.
