Postdoctoral UDL (Researcher and Lecturer)

Juan Enrique Garrido Navarro received his PhD in Computer Science by the University of Castilla-La Mancha in July 2014. He was factulty member at the University of Lleida since 2016 up to 2023. During his time in Lleida he was coordinator of the MS in Informatics Engineering at UdL, the first official master program in Spain with dual training modality and the MS in UX Design, an international and interuniversiary program offered by UdL and UNAD (Colombia).

His research experience is focused on Human-Computer Interaction. The main topics of interest are movement interaction, natural interaction, ubiquity and awareness. In this sense, the objective is to find solutions for our daily lives in specific domains such as healthcare.

Assistant Professor at UdL

Félix Albertos Marco was born in Caudete (Albacete, Spain) the 1st of august, 1977. He had his first computer at the age of 19, a custom Pentium 100, 16Mb RAM, 1Mb video, and no sound :-). Since then, he worked to understand how computers work and, lately, to understand how users use computers.

He works in the field of Human-Computer Interaction (HCI). He is a member of the AIPO (Asociación Interacción Persona-Ordenador, Human-Computer Interaction). His main interest is the user interaction with the Web and how users perform their tasks on nowadays scenarios, focusing on distributed interactions and multi-device environments. He is also interested on collaborative environments and e-Learning Web Applications.

User experience methodology for the design and evaluation of interactive systems (PhD)

Heuristic evaluation is one of the most used and discount usability evaluation methodologies. However, it has some manual steps that could be semi-automated to decrease the time spent to carry out the methodology and, in consequence, the budget invested in the development process of an interactive system. In addition, the quality of a product has evolved, in general terms, from the usability to the user experience. Therefore, according to both aspects, manual steps of the heuristic evaluation and evolution towards user experience, a new methodology based on heuristics is proposed for considering user experience in the design and evaluation steps of the development process of an interactive system. This methodology semi-automates the selection of the best heuristics for a specific interactive system, it supports heuristic evaluation per se and, finally, it provides quantitative, qualitative, summative and formative results through the ISO/IEC 25062:2006 standard for software engineering. Software product Quality Requirements and Evaluation (SQuaRE). Common Industry Format (CIF) for usability test reports. Furthermore, this methodology is implemented in Open-HEREDEUX: Open HEuristic REsource for Designing and Evaluating User eXperience.

Interacting with semantic web data through an automatic information architecture (PhD)

The proliferation of Linked Open Data and other data publishing initiatives has increased the amount of data available for analysis and reuse. However, in most cases it is very difficult for users to explore and use this data, especially for those without experience with semantic web technologies. Our contribution to solving this problem is applying the Visual Information-Seeking Mantra: “Overview first, zoom and filter, then details-on-demand”, which is implemented using Information Architecture components automatically generated from data and ontologies. This thesis offers algorithms and methods to automatically generate and drive the information architecture components for websites based on semantic web data. Through these components, it is possible to explore and visualize data. Moreover, even lay-users are capable of building complex queries without requiring to learn complicated technologies or knowing the vocabularies used in the explored datasets. This approach has been implemented and tested in Rhizomer, a tool capable of publishing Semantic Web datasets while facilitating user awareness of the published content. Our contributions have been validated with end users as part of a User Centred Design development process.
