One of the many areas in which artificial intelligence (AI) techniques are used is the development of systems for the recognition of vital emotions to control human health and safety. This study used biometric sensors in a multimodal approach to capture signals in the recognition of stressful situations. The great advances in technology have allowed the development of portable devices capable of monitoring different physiological measures in an inexpensive, non-invasive, and efficient manner. Virtual reality (VR) has evolved to achieve a realistic immersive experience in different contexts. The combination of AI, signal acquisition devices, and VR makes it possible to generate useful knowledge even in challenging situations in daily life, such as when driving. The main goal of this work is to combine the use of sensors and the possibilities offered by VR for the creation of a system for recognizing stress during different driving situations in a vehicle. We investigated the feasibil...

The predominant means of communication is speech; however, there are persons whose speaking or hearing abilities are impaired. Communication presents a significant barrier for persons with such disabilities. The use of deep learning methods can help to reduce communication barriers. This paper proposes a deep learning-based model that detects and recognizes the words from a person’s gestures. Deep learning models, namely, LSTM and GRU (feedback-based learning models), are used to recognize signs from isolated Indian Sign Language (ISL) video frames. The four different sequential combinations of LSTM and GRU (as there are two layers of LSTM and two layers of GRU) were used with our own dataset, IISL2020. The proposed model, consisting of a single layer of LSTM followed by GRU, achieves around 97% accuracy over 11 different signs. This method may help persons who are unaware of sign language to communicate with persons whose speech or hearing is impaired.

The paradigm of Learning Object provides Educators and Learners with the ability to access an extensive number of learning resources. To do so, this paradigm provides different technologies and tools, such as federated search platforms and storage repositories, in order to obtain information ubiquitously and on demand. However, the vast amount and variety of educational content, which is distributed among several repositories, and the existence of various and incompatible standards, technologies and interoperability layers among repositories, constitutes a real problem for the expansion of this paradigm. This study presents an agent-based architecture that uses the advantages provided by Cloud Computing platforms to deal with the open issues on the Learning Object paradigm.

E-Commerce is a business form that has grown in popularity in our society. E-Commerce applications are so consolidated in a certain kind of areas, and also have a very promising road in many others. In this way, new technologies have been applied to give an adequate response to this kind of software. One of these technologies is the agent technology that has found in the e-commerce one of the major application area. Our work is devoted to develop an e-commerce system that is especially thought for small and medium enterprises (SMEs), where several enterprises share a common mediated e-commerce site. Concretely, in this paper we present an e-commerce architecture definition proposal that is based on an agent-oriented technology, but also compliant with our past work in this area. This architecture establishes the basis for our future work on e-commerce solutions development, making near the e-business world to the small enterprises.

Blockchain technology is used as a distributed ledger to store and secure data and perform transactions between entities in smart grids. This paper proposes a platform based on blockchain technology and the multi-agent system paradigm to allow for the creation of an automated peer-to-peer electricity market in micro-grids. The use of a permissioned blockchain network has multiple benefits as it reduces transaction costs and enables micro-transactions. Moreover, an improvement in security is obtained, eliminating the single point of failure in the control and management of the platform along with creating the possibility to trace back the actions of the participants and a mechanism of identification. Furthermore, it provides the opportunity to create a decentralized and democratic energy market while complying with the current legislation and regulations on user privacy and data protection by incorporating Zero-Knowledge Proof protocols and ring signatures.

[ES]La usabilidad es el grado en que un producto puede ser utilizado por los usuarios para lograr sus propósitos con efectividad, eficiencia y satisfacción en un determinado contexto de uso (ISO 9241-11). Se trata de conseguir productos que sean más fáciles de usar y que satisfagan mejor las necesidades reales de los clientes. Un diseño no es en sí mismo usable, lo es para usuarios específicos en contextos de uso específicos. Son varias las razones que nos llevan a realizar esfuerzos encaminados a cuidar los aspectos de usabilidad. No cabe duda de que un sitio Web con una buena usabilidad mejora su posición frente a sus competidores. En cualquier tipo de producto es deseable la facilidad de uso pero esto es especialmente importante en la Web, en la que un usuario que no se sienta cómodo o que encuentre dificultades para desenvolverse tiene una gran facilidad para buscar otro sitio que responda mejor a sus expectativas (recuérdese el tópico: “en la Web la competencia está a un clic de distancia”). En este capítulo se presentan bases sobre las que se asienta esta tecnología.[EN]Usability is the degree to which a product can be used by users to achieve their purposes with effectiveness, efficiency and satisfaction in a given context of use (ISO 9241-11). The aim is to achieve products that are easier to use and that better meet the real needs of customers. A design is not in itself usable, it is usable for specific users in specific contexts of use. There are several reasons that lead us to make efforts to take care of usability aspects. There is no doubt that a website with good usability improves its position in front of its competitors. Ease of use is desirable in any type of product, but this is especially important in the Web, where a user who does not feel comfortable or who finds it difficult to navigate has a great facility to find another site that better meets their expectations (remem-ber the topic: "on the Web the competition is a click away"). In this chapter we present the bases on which this technology is based

Abstract Following data ethics and respecting the clients’ privacy, the banking environment can use the client data that is available to them to offer personalized services to its clients. Intelligent recommender systems can support this attempt through specialized technological architectures. This article proposes the inclusion of CEBRA (CasE-Based Reasoning Application), a case-based reasoning system oriented to commercial banking, in a Fog Computing architecture coordinated by virtual agents. Throughout this article, the model of this architecture is presented and its life cycle is described, and improvements are proposed through the incorporation of several techniques in the retrieve and reuse phases, including the extraction of interests expressed by users on their social network profiles and collaborative filtering systems. A comprehensive case study has been carried out and a dataset of 60,000 cases has been generated to evaluate CEBRA. As a result, the Recommender System is presented, by including, the recommendation algorithm and a REST interface for its use. The recommendations are based on the user’s profile, previous ratings and/or additional knowledge such as the user’s contextual information. The proposal takes advantage of contextual information to support the promotion of banking and financial products, improving user satisfaction.

The aim of this article is to highlight the benefits of implementing an active learning methodology in classes delivered to engineering degree students in Spain. The proposed teaching methodology has been designed for subjects with assessable practices and a high number of students in Computer Engineering degrees. The methodology is based on the redefinition of roles in the work assessment process where collaborative learning methods are incorporated. The idea of this approach is that students work closely together to learn from each other and that they are responsible for their own learning and that of fellow classmates. Moreover, they learn from participating in the process of assessing the work of their peers. This research describes the implementation of this technology and its promising results. Students increase their activity because they assume the role of solver of the proposed assignment in pair programming and also as evaluator of those of others due peers’ protocol. The ...

RESUMEN La creación de contenidos o recursos educativos hipermedia de calidad, destinados a satisfacer la creciente demanda de cursos orientados a una e-formación, es uno de los problemas con los que se encuentra este sector. Las herramientas de autor están pensadas para facilitar esta labor creativa, pero la realidad demuestra una escena que es especialmente desalentadora para muchos docentes, al encontrarse que estas herramientas están pensadas para un usuario con amplios conocimientos en informática, debido fundamentalmente a que implementan un modelo de interacción muy complejo que en la mayoría de los casos excede con creces las necesidades de estos usuarios. Con objeto de paliar este problema se ha desarrollado HyCo (Hypertex Composer), una herramienta de autor que implementa un modo de operación muy sencillo, donde el modelo de interacción ha sido pedagógicamente diseñado para rescatar a estos autores que, con amplio potencial y experiencia, no se acaban de integrar en este m...
