2019 , Calle-Jimenez T. , Sanchez-Gordon S. , Rybarczyk Y. , Jadán Guerrero, Janio , Villarreal S. , Esparza W. , Acosta-Vargas P. , Guevara C. , Nunes I.L.

This paper explains some of the challenges that exist to make accessible the web interfaces of a Tele-rehabilitation platform for hip arthroplasty patients and propose an iterative method to improve the level of accessibility using automatic evaluation tools. Web accessibility is not concerned with the specific conditions of people who use the Web, but with the impact that their conditions have on their ability to use it. If the web interfaces of the Tele-rehabilitation platform for hip arthroplasty patients are not accessible enough, the patients will not be able to understand, perceive or operate adequately the platform to benefit completely of the physical therapy. The Web Content Accessibility Guidelines (WCAG 2.0) provides a set of rules and recommendations to help solve the problems of Web accessibility. Additionally, there are evaluation tools that allow identifying main web accessibility problems. These tools are best exploited when used by accessibility experts. The purpose of this research is threefold. First, to present the results of a web accessibility evaluation of the web interfaces of the Tele-rehabilitation Platform for Hip Arthroplasty Patients using three the evaluation tools: WAVE, AChecker and TAW. Second, to analyze the results presented by the tools according to the WCAG 2.0 guidelines to define a list of accessibility improvements. Third, to implement the improvements through the re-factorization of the existing code and re-testing the improved web interfaces to verify that they meet acceptable accessibility levels. © Springer International Publishing AG, part of Springer Nature 2019.

Artificial Intelligence and Tomorrow’s Education

2021 , Cóndor-Herrera, Omar , Arias Flores, Hugo Patricio , Jadán Guerrero, Janio , Ramos Galarza, Carlos

Nowadays, there is a rapid technological progress around the world that has enabled realities long ago unimaginable. We live in a technological era that represents new possibilities and challenges for society, and for the educational models in each country [1]. Research on smart education, which has forced the educational community to rethink on new ways of learning and teaching has been developed globally. Due to the advent of artificial intelligence (AI), the educational model for both, teachers and students will change. Nevertheless, to transform educational systems, it is necessary to update and train students, educators, and administrators effectively [2]. This research aims to describe the possible applications of AI in education from: 1) the automation of administrative tasks; 2) collection and analysis of information [3] to create smart content; 3) the implementation of virtual assistants in the teaching-learning process; 4) the potential delivery of lectures by humanoid robots with AI. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Rehabilitation of Children Affected by Attention Deficit Disorder

2021 , Ramos Galarza, Carlos , Acosta-Rodas P. , Jadán Guerrero, Janio , Bolaños-Pasquel, Mónica , Saez-Delgado F.

This paper presents the conceptual development of a technological application for the treatment of children with attention deficit disorder (ADD). This technological application will consist on serious-gaming to stimulate the different levels of attention. The first level is focused in attention and stimulates it by identifying stimuli through tactile interaction with the user. The second level is selective attention, for which, the child must select a stimulus leaving the irrelevant stimuli aside. The third level will work on sustained attention, where the child must fulfill a game with a longer duration. The next level will contain an activity to stimulate alternating attention, where the child must solve two tasks by alternating the focus of attention. Finally, for the divided attention, it must be resolved two tasks at the same time. With this application it is expected to improve the child’s motivation in the treatment and provide an intervention tool for the clinician. © 2021, The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG.

Accessibility assessment in mobile applications for android

2020 , Acosta-Vargas, P. , Salvador-Ullauri, L. , Jadán Guerrero, Janio , Guevara Maldonado, César Byron , Sanchez-Gordon, S. , Calle-Jimenez, T. , Lara Álvarez, Patricio , Medina, A. , Nunes, I.L.

At present, the lack of adequate methods to test whether a mobile application is accessible has become a major challenge for accessibility experts. This study was applied to ten mobile applications, the most popular according to PCMAG. We propose to use the Web Content Accessibility Guidelines 2.1 through manual review and automatic review with the Google Play Store Accessibility Scanner validator for the Android. The evaluation results of the mobile applications indicate that the applications are not accessible because they do not comply with the minimum required level proposed by WCAG 2.1. The research proposes suggestions to improve and raise awareness among the designers of mobile applications, in such a way that more inclusive mobile applications accessible to all types of users are built. © Springer Nature Switzerland AG 2020.

Fundamental concepts in the neuropsychological theory [Conceptos fundamentales en la teoría neuropsicológica]

2017 , Ramos Galarza, Carlos , Ramos V. , Jadán Guerrero, Janio , Lepe-Martínez N. , Paredes-Núñez L. , Gómez-García A. , Bolaños-Pasquel, Mónica

This article presents three concepts that are fundamental in the neuropsychological theoretical: (a) historical data in the study of the human brain, (b) neuropsychological evaluation of brain functions and (c) neuropsychological rehabilitation of brain functions. As relevant data in the theoretical development of the study of the human brain is a tour of the trepanation acts performed hundreds of years ago, the contributions of phrenology, the masterful findings of Broca and Wernicke, the heuristic contribution of Luria and the current revolution with the neuro-image. In the neuropsychological evaluation of brain functions, the role of specific, non-specific and delayed observation tests in the interpretation of the neuropsychological state of the human being is analyzed, which allow analyzing neuropsychological functions in the laboratory and in real lifeactivities. Finally, we analyze the process of neuropsychological rehabilitation of brain functions, where mention is made of the processes of restoration, compensation, substitution, activation-stimulation and integration, which are very useful when intervening in a brain that has suffered an acquired damage. It is concluded that the current accelerated pace has determined the advance of neuroscience, where technology and the forceful scientific contribution propose new techniques and theories to understand the processes of evaluation and rehabilitation of brain functioning.

Building hybrid interfaces to increase interaction with young children and children with special needs

2020 , Jadán Guerrero, Janio , Guevara Maldonado, César Byron , Lara Álvarez, Patricio , Sanchez-Gordon, S. , Calle-Jimenez, T. , Salvador-Ullauri, L. , Acosta-Vargas, P. , Bonilla-Jurado, Diego

Young children as well as children with special educational needs learn from their environment with social, emotional and physical stimuli. In this context, educational resources and teaching strategies play a main role for them in order to understand the new information. This paper describes the experience of building hybrid interfaces that combine technology with traditional educational resources. A total of 60 teachers divided in two groups completed some tasks which consisted of generating new educative resources with tecnology. Through Design Thinking methodology, teachers designed three hybrid interfaces: 1. Interactive books, combining traditional fairy tales books with mobile devices, where QR codes and NFC tags give life to the stories; 2. Educational Board Games, where augmented reality markers give an extra information to the players; 3. Tangible educational resources, which integrate Makey-Makey device and Scratch with fruit, clay, aluminum foil or water to build laboratory. © Springer Nature Switzerland AG 2020.

Gender Bias in Chatbots and Its Programming

2023 , Illescas C. , Ortega T. , Jadán Guerrero, Janio

Nowadays, digital transformation in business seeks to maximize the efficiency of its own processes through automation. These changes will be successful if the process of adaptation and change management is properly carried out. One of the main tools to achieve these transformations is the chatbot. This key technology will help embrace these changes and transformations; however, there have been processes in which their interactions show bias, as inclusive interaction is missing. This research focuses on two main points: first, to identify whether the user is capable of recognizing any bias variables in chatbots and second, to analyze if these variables have an impact when there is an adoption of new technologies in any digital transformation and business goals. The faster and more in depth a company understands the bias and its impact in the target audience, the better automation will be adopted. As a result, chatbots will be properly used to achieve and increase business goals. Some undoubtable chatbot uses in marketing are personalized service, facilitate sales, and trigger client’s satisfaction. Most importantly, gathering valuable data for analysis, predictive business models and trends into virtually for any product or service intended to promote. After consulting +150 chatbot users, it can be concluded that it is a proven fact that gender bias is present, also, there is a high trend and acceptance of chatbots with female voices and characteristics, which can be balanced if there is awareness around this topic among developers and change management teams seeking adoption of new technologies. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
