Sustainable Development Goal 4 from the United Nations 2030 Agenda, focus on ensuring inclusive and equitable quality education and promoting lifelong learning opportunities for all. Inclusive education is a key component of sustainable development goal 4, and assistive technology is a critical factor in achieving it. In this context, this paper introduces the development of an immersive virtual reality system with conversational skills for inclusive learning processes. The idea of this work is to provide an assistive technology to motivate, educate, and train students with disabilities in a more inclusive way. In order to improve the user experience, the system was developed to work in a CAVE-like immersive environment using Natural Language Processing through a Semantic Embodied Conversational Agent. This work highlights that assistive technology can promote educational, psychological, and social benefits for students with disabilities. The use of assistive technology can enable academic engagement and social participation and be transformative from a psychological perspective. A case study was conducted on children with autism, which showed encouraging results of the system as an assistive technology for teaching and learning.

Exergames are a good alternative to perform physical activity while being entertained with a video game. This paper reviews the history of exergames with walkin-place mechanisms for locomotion, and presents the development of a prototype video game controller (gamepad) with functionalities to sense the player’s movements (walk, run, and jump). Then, an exergame that was implemented and integrated with the controller is described. This proposal was evaluated by users considering usability and user experience analysis. The results obtained allow affirming that the gamepad integrated with the video game were positively valued by the participants during the test sessions and allowed the realization of physical activity while maintaining entertainment through the game.

The visibility of women in the labor context of software production is very weak, due to their low participation and socio-cultural difficulties to grow in the labor context. This article aims to show women's role and contribution in the whole life cycle of software development and thus promote gender equity and equality in this area. Methodologically, we have taken the systematic mapping technique to search in the technical literature as a basis. This allows us to obtain a comprehensive view of the work related to gender gaps women face in their work performance in software manufacturing. To complement this study, a form including closed questions was designed to obtain information about the role women play in software production and their expectations in terms of their professional contribution in this field. The main findings allow us to infer that there are biases when defining leaders and roles in software development. It is hoped that the findings of this study will provide inspiring information for women who wish to lead teams in the field of software development by showing the reduction of gender gaps and the possibility of successfully exercising leadership in this field.

Emerging technologies, e.g., cloud computing, artificial intelligence, robotics, and information technologies, facilitate digital transformation and promote digital services. Significant research exists on the acceptance and use of technologies and specific digital transformation (DT) practices. However, more research is needed to better understand user’s acceptance and how they use technology to better de-sign digital services. Thus, this paper: 1) proposes a Systematic Literature Re-view (SLR) of the models of acceptance and use of technologies, as well as of certain DT practices applied to the human-computer interaction (HCI) of digital services; 2) provides an analysis of the results of the behavior of the factors and practices; and 3) proposes a taxonomy of the acceptance and use factors applied to HCI of digital services by economic activity. The main contribution of this work is the proposed taxonomy in a vacancy area relevant to digital transformation efforts applied to digital services pursued globally, both in the private and public sectors.

The evaluation of human-machine interfaces (HMI) requires quantitative metrics to define the ability of a person to effectively achieve their goals using the HMI. In particular, for pointing-device type HMIs such as the computer mouse, an experiment quantifying movement by performing repetitive target selections allows defining a useful metric known as throughput (TP) using the Fitts’ Law test. In this work, a dataset obtained from an automated protocol application is presented, which is made publicly available through an on-line platform. A post-processing method to obtain performance parameters from the dataset is also presented, and its output is used to validate the data against similar experiments in the literature.

On the Internet, we find a large amount of information from government institutions that has been published in open format. However, only a part of these data is available in standard formats such as Resource Description Framework (RDF), and to a lesser extent, is published as Linked Open Data (LOD). The main objective of the research presented in this paper is to identify problems and tools used in the process of publishing LOD with the purpose of establishing a basis for the construction of a future framework that will help public institutions to facilitate such processes. To fulfill the objective, we conducted a systematic literature review in order to assess the state-of-the-art in this matter. The contribution of this work is to identify the frequent problems that arise in the LOD publishing process. It also provides a detail of the frameworks proposed in scientific papers grouping the technical tools by phases that correspond to the LOD publication life cycle. In addition, it compiles the characteristics of the ETL (Extract-Transform-Load) tools that predominate in this review, such as Pentaho Data Integration (Kettle) and OpenRefine.

Reducing the amount of annotated data required to train predictive models is one of the main challenges in applying artificial intelligence to histopathology. In this paper, we propose a method to enhance the performance of deep learning models trained with limited data in the field of digital pathology. The method relies on a two-stage transfer learning process, where an intermediate model serves as a bridge between a pre-trained model on ImageNet and the final cancer classification model. The intermediate model is fine-tuned with a dataset of over 4,000,000 images weakly labeled with clinical data extracted from TCGA program. The model obtained through the proposed method significantly outperforms a model trained with a traditional transfer learning process.

Nowadays, due to the increasing presence of artificial intelligence in software systems, development teams face the challenge of working together to integrate tasks, resources, and roles in a new field, named AI Engineering. Proposals, in the way of models, highlight the needs of integrating two different perspectives – the software and the decision-making support (big data, machine learning, and so on) systems. But there is something more – both systems must achieve high quality levels for different properties; and this is not a straightforward task. Quality properties, such as reusability, traditionally evaluated and reinforced through modeling in software systems, do not exactly apply similarly in decision-making support systems. In this paper, we propose a model for managing reusable assets in AI engineered systems by linking software product line modeling and variety identification. The proposal is exemplified through a case study in the agriculture domain.

Technological advances in recent years have promoted the development of virtual reality systems that have awide variety of hardware and software characteristics, providing varying degrees of immersion. Immersionis an objective property of the virtual reality system that depends on both its hardware and softwarecharacteristics. Virtual reality systems are currently attempting to improve immersion as much as possible.However, there is no metric to measure the level of immersion of a virtual reality system based onits characteristics. To date, the influence of these hardware and software variables on immersion hasonly been considered individually or in small groups. The way these system variables simultaneously affectimmersion has not been analyzed either. In this paper, we propose immersion metrics for virtualreality systems based on their hardware and software variables, as well as the development process that ledto their formulation. From the conducted experiment and the obtained data, we followed a methodology togenerate immersion models based on the variables of the system. The immersion metrics presented in thiswork offer a useful tool in the area of virtual reality and immersive technologies, not only to measurethe immersion of any virtual reality system but also to analyze the relationship and importance of thevariables of these systems.
