    Dealing with Uncertainties in IT Solutions for Agriculture
    (Springer, Cham, 2025) Antonelli, Leandro; Collazos, Cesar; Zarate, Pascale; Agredo Delgado, Vanessa; Camilleri, Guy; Fernández, Alejandro; Hernandez, Jorge E.; Torres, Diego
    Technology is essential for the improvement and efficiency of activities in the agricultural environment. Nevertheless, farmers and IT’s worlds are distant. Usually, IT services fail to provide the correct solution and farmers are reluctant to incorporate new IT advances. IT teams need to acquire agricultural knowledge and language in order to communicate, to reduce the distance, and cooperate. Nevertheless, during this process and particularly, in agriculture, there are many uncertainties. If they are not clearified, it will not be possible to provide the right IT solution. These un-certainties are translated as a lack of precision in the requirements specifica-tions. Sometimes, it is as easy as elicit more information from the stake-holders to improve the specification. In some other situations, the stakeholders have different points of view and they need to reach a concen-sus. These uncertainties are hard to identify. IT teams and farmers must speak the same technical and specific language and the IT team needs a complete and exhaustive specification about how software applications must react. Agriculture is a biological environment with many rules and de-cisions that are not easy to make explicit. Therefore, it is important to in-volve a group of farmers as with complementary and different point of view. Thus, this article proposes an approach to deal with uncertainties in order to provide the unambiguous and complete specification. The approach relies on capturing knowledge through scenarios. It consists of three main steps to obtain the scenarios: (i) a collaborative knowledge acquisition, (ii) scenarios description and analysis, and (iii) group decision support.

    Agroknowledge: co-creation of a repository of agricultural best practices, to improve knowledge disemination and interoperability
    (Springer, Cham, 2025) Torres, Diego; del Pino, Mariana; Gamboa, Susana; Antonelli, Leandro; Martin, Jonathan; Lombardelli, Julieta; Fernández, Alejandro
    Good Agricultural Practices (GAP), as defined by FAO, are a "collection of principles for on-farm production and post-production processes, resulting in safe and healthy food and non-food agriculture products, while considering economic, social and environmental sustainability." GAP are about understanding, planning and measurement, record, and management to achieve specific social, environmental, and productive objectives. GAPs goals are: to ensure food safety, to produce in a way that protects the environment and avoids its degradation, to ensure job well-being, and to obtain quality products according to consumer demand. For example, FAO enumerates general categories such as GAP for food safety, to improve market access or ensure water quality. GAP can be achieved by different actions depending on the crop, geography, available tools, and a diversity of variables. A federated catalog of GAPs that could be accessed by different stakeholders using different aspects is desirable. Also, as there are a diversity of GAPs experiences in the world, a catalog about those experiences is a helpful tool to help farmers exchange and adoption of knowledge. This chapter presents a semantic wiki repository that focuses on GAPs related to intensive horticultural activity in aspects that may be subject to improvement. The repository is framed in what is currently considered a collaborative repository. The wiki includes a description, goals, and methodologies of each good practice defined in GAP. Also, the wiki contains links to tutorials, external sites about the agricultural field, and legal documentation.

    Adopting and Adapting Design Thinking's Strategies in Distributed Research and Innovation Projects: A Case Study
    (Springer, Cham, 2025) Challiol, Cecilia; Rodríguez, Andrés; Baumont de Olivera, Francis; Fernández, Alejandro
    Innovation is risky and challenging by definition. Only a small fraction of all innovation initiatives result in a successful new material, process or product. Networked research projects, as those conducted by a distributed consortium in-volving multiple domains and with global coverage, constitute an opportunity for innovation. However, the distributed nature of these projects introduces additional challenges, not present otherwise. The RUC-APS project is a European funded project whose goal is to enhance and implement knowledge based ICT solutions within high risk and uncertain conditions for agriculture pro-duction systems. Partners in the RUC-APS consortium are located in France, Italy, Poland, Spain, the United Kingdom, Argentina and Chile. Some of these partners are academic institutions, and some are companies, farms, or government dependent organizations. Partners have expertise in different domains such as computers sci-ence, business management, and agriculture. Interaction among partners —two or three partners at a time— takes place regularly throughout the year, in periods of one or two months of duration. This paper reports on a case study in which strategies of Design Thinking —which heavily depends on co-located, face to face interac-tion— were adapted to the distributed nature of the project. A proposal of how to adopt and adapt DT in distributed research and innovation projects is presented. In addition, a discussion is presented in relation to this kind of approach.

    GAP-a-Farm: A tool to support GAP compliance and information based decision making in horticulture
    (Springer, Cham, 2025) Fernández, Alejandro; Marconi, Andres; del Pino, Mariana; Baumont de Oliveira, Francis; Hernández, Jorge
    Adoption of information technology in horticulture is low, especially in developing countries. Governments across the world issue new regulation to govern the application of good agricultural practices affecting production, storage and selling activities, while certification program require that farmers keep detailed records of farm events, for auditing purposes. These changes in the context of horticultural practices, represent an opportunity to test whether a compliance and decision support systems can shift farmers processes to utilize technology incorporating data and expert advice. GAP-a-Farm is a tool to ease record keeping, and to turn recorded data into alerts and advice. This chapter documents the key aspects of the system’s design, and reports on preliminary discussions with end-users that take part in a pilot study in Argentina.

    Evaluation of a Model-Driven Proposal to the Development of Groupware Systems
    (2022) Bibbo, Luis Mariano; Pons, Claudia Fabiana; Fernández, Alejandro; Zhao, Jingyuan; Richards, Joseph
    Building groupware is a complex task. This chapter presents the use of the domain-specific language CSSL v2.0 collaborative software system language. CSSL provides simplicity, expressiveness, and precision to model the main concepts of collaborative systems, especially collaborative processes, protocols, and awareness. Models of collaborative systems are created via visual editors that support the concrete syntax of CSSL. According to the MDD methodology, models are independent of the implementation platform and are formally prepared to be transformed. In this implementation, the target of the transformation is a web application that provides a set of basic functions that developers can refine. Evaluation, validation, and verification of the language is performed, determining that the CSSL tools allow developers to solve central aspects of collaborative systems implementation in a simple and reasonable way. The evaluation determined that the CSSL metamodel has low complexity, with semantics strongly associated with UML and with good configuration possibilities.

    Studying the User Experience of an Educational AR-Based App for Smart Glasses
    (Springer, 2022) Santana, Ronny; Rossi, Gustavo Héctor; Rybarczyk, Yves; Méndez, Gonzalo Gabriel; Vera, Francisco; Rodríguez, Andrés; Mendoza, Patricio
    The steady evolution of wearable technology—along with augmented reality (AR)—has enabled important advances in teaching and learning. We present STEM Education, an interactive AR application for smart glasses. We evaluate the app’s user experience (UX) with undergraduate STEM (Science, Technology, Engineering, and Mathematics) students. More specifically, we focus on the students’ overall satisfaction, degree of technological acceptance, mental workload, and emotional response. Our observations suggest that the app improves the student’s learning quality, while promoting high levels of engagement and satisfaction. We discuss these findings and their implications in the design of similar technology for educational contexts.

    Historia de la IPO/HCI
    (2022) Rodríguez, Andrés
    Conocer la historia de las disciplinas que se enfocan en la interacción entre personas y ordenadores es una buena manera de poner en valor el origen de principios y herramientas que hoy damos por sentado, como si hubieran existido desde siempre y obedecieran a algún tipo de orden natural de las cosas. Además, es sabido que no siempre lo que nos trajo hasta aquí será lo mismo que nos lleve hacia dónde queremos ir. Explicitar algunas de las tendencias históricas puede ayudarnos a decidir qué deberíamos hacer de manera distinta si queremos modificar ese curso. Este capítulo es un brevísimo resumen histórico de una disciplina que ha sabido conjugar muy bien sus variantes académica (conocida como Interacción Persona Ordenador, IPO) y profesional (el Diseño de Experiencias de Usuario, DUX). Presentamos algunos hechos y personajes fundacionales, ideas que los motivaron y caminos que abrieron. Recorremos los hitos que nos han traído desde la propuesta de una máquina para extender la memoria humana hasta los dispositivos ubicuos y conectados con los que convivimos hoy y que en muchos casos parecen conocernos mejor que nosotros mismos y anticiparse a nuestras necesidades y deseos.

    Desafíos de usabilidad de aplicaciones nómadas en el automóvil
    (2022) Carvajal Lema, Carlos; Luna-García, Huizilopoztli; Rodríguez, Andrés; Fernández, Alejandro
    Investigadores de la Interacción Humano-Computador han trabajado durante décadas definiendo métodos y técnicas para evaluar la demanda de atención de los sistemas de información en el vehículo (IVIS). La mayoría de métodos requieren entornos de prueba costosos y personal altamente capacitado para su implementación. En el ámbito de los ecosistemas de aplicaciones móviles (también conocidos como «apps»), existen pautas y programas de certificación. Las aplicaciones deben pasarlas para que se consideren sistemas preparados para el entorno automotriz. Sin embargo, entrar en la categoría de aplicaciones certificadas no garantiza el pleno cumplimiento de los criterios establecidos por los métodos formales aceptados por la industria automotriz y estándares internacionales. Además, numerosos estudios muestran el alto riesgo de utilizar IVIS durante la conducción, lo que lleva a considerar que los actuales enfoques predominantes para evaluar las demandas de atención de las aplicaciones de automoción y como guía para el diseño de IVIS no son suficientes. Los métodos costo beneficio eficientes aplicables en las primeras fases de desarrollo de aplicaciones, así como las interfaces adaptables al contexto, tienen el potencial de contribuir a la mejora de los entornos de conducción seguros.

    A User Interface for Consistent AHP Pairwise Comparisons
    (Springer, Cham, 2021) Cimadamore, Andrés; Fernández, Alejandro; Ye, Chenhui; Zaraté, Pascale; Kamissoko, Daouda
    Decision Makers generally reason on several criteria, aiming to obtain a total consistency or partial order of several alternatives. MultiCriteria analysis is based on the assumption that such ordering exists. Decision Makers are supported by several kinds of approaches or tools. One approach consists in comparing the criteria two by two, i.e. pairwise comparison, to find the relative importance of each criterion. This relative importance, called weight of criteria, is used to find the final order of alternatives. One methodology, developed by Saaty, called Analytical Hierarchical Process (AHP), is based on this principle of pairwise comparison. Having the weights of criteria, the decision makers have then to compare the alternatives two by two for each criterion. Pairwise comparisons are simple to use; however, as the number of items to compare increases, so do the effort of conducting all comparisons and the probability of introducing inconsistencies. In this article we present an innovative approach to conduct pairwise comparisons based on a UI widget that resembles an interactive data plot. It uses the transitivity property of a consistent comparison matrix to infer comparisons. Our hypothesis is that this new approach is more efficient (as it reduces the number of actions the user must conduct to compare all items), more effective (as it limits the sources of inconsistencies), and yields better user satisfaction. We conducted a controlled experiment involving 50 participants. We observed that the proposed widget reduces the effort of making pairwise comparisons, improves the consistency of the comparisons, and leads to a better user experience.

    Optimizing a Gamified Design Through Reinforcement Learning - A Case Study in Stack Overflow
    (2021) Martin, Jonathan; Torres, Diego; Fernández, Alejandro
    Gamification can be used to foster participation in knowledge sharing communities. While designing and assessing the potential impact of a gamification design in such a context, it is important to avoid work disruption and negative side effects. A gamification optimization approach implemented with deep reinforcement learning based on play-testing approaches helps prevent possible disruptive configuration and has the capability to adapt to different communities or gamification targets. In this research, a case of study for this approach is presented running over the Stack Overflow Q&A community. The approach detects the best configuration for a Contribution, Reinforcement, and Dissemination (CRD) gamification strategy using Stack Overflow historical data in a year. The results show that the approach funds proper gamification strategy configurations. Moreover, those configurations are robust enough to be applied along the time unseen periods.
