Item Usability Study of a Pilot Database Interface for Consulting Open Educational Resources in the Context of the ENCORE Project(Springer, 2023-07-23) Vázquez-Ingelmo, A.; García-Holgado, A.; García-Peñalvo, F. J.; Chiarello, F.Open educational resources (OER) are materials such as textbooks, lessons, and other teaching and learning tools that are freely accessible for use. OER are gaining popularity as a means for educators to give their students access to high-quality, economical educational materials. OER can encourage sharing infor-mation and resources throughout the educational community while also helping lower the cost of education for both students and teachers. In this context, the ENCORE project seeks, among other goals, to assist students and workers in acquiring the skills necessary to deal with economic, ecological, and technolog-ical challenges as well as to address the skills gap between the supply of educa-tional institutions and the demand of employers and assist educators in staying abreast of the constantly changing landscape of skills. One of the first steps to reach the project’s goals is to build a robust database that contains quality OERs linked to green, digital, and entrepreneurial (GDE) skills. A graphical interface has been developed to retrieve and display information about the OERs, and, in turn, to make these resources available for any stakeholder. However, due to the significant quantity of information, it is important to develop an interface that enhances user experience. This work presents a usability study of the ENCORE project’s OER database interface carried out through a System Usability Scale (SUS) questionnaire, as well as future interface improvements based on the results.Item Are Textual Recommendations Enough? Guiding Physicians Toward the Design of Machine Learning Pipelines Through a Visual Platform(Springer, 2023-09-05) Vázquez-Ingelmo, A.; García-Holgado, A.; García-Peñalvo, F. J.; Pérez-Sánchez, P.; Antúnez-Muiños, P.; Sánchez-Puente, A.; Vicente-Palacios, V.; Dorado-Díaz, P. I.; Sánchez, P. L.The prevalence of artificial intelligence (AI) in our daily lives is often exaggerated by the media, leading to a positive public perception while overlook-ing potential problems. In the field of medicine, it is crucial to educate future health-care professionals on the advantages and disadvantages of AI and to emphasize the importance of creating fair, ethical, and reproducible models. The KoopaML platform was developed to provide an educational and user-friendly interface for inexperienced users to create AI pipelines. This study analyzes the quantitative and interaction data gathered from a usability test involving physicians from the University Hospital of Salamanca, with the aim of identifying new interaction paradigms to improve the platform’s usability. The results shown that the plat-form is difficult to learn for inexperienced users due to its contents related to AI. Following these results, a set of improvements are proposed for the next version of KoopaML, focusing on reducing the interactions needed to create the pipelines.Item Psychiatric patients tracking through a private social network for relatives: development and pilot study(Springer, 2016-07) García-Peñalvo, F. J.; Franco Martín, M.; García-Holgado, A.; Toribio Guzmán, J. M.; Largo Antón, J.; Sánchez-Gómez, M. C.The treatment of psychiatric patients requires different health care from that of patients from other medical specialties. In particular, in the case of Department of Psychiatry from the Zamora Hospital (Spain), the period of time which patients require institutionalized care is a tiny part of their treatment. A large part of health care provided to the patient is aimed at his/her rehabilitation and social integration through day-care centres, supervised flats or activities. Conversely, several reports reveal that approximately 50% of Internet users use the network as a source of health information, which has led to the emergence of virtual communities where patients, relatives or health professionals share their knowledge concerning an illness, health problem or specific health condition. In this context, we have identified that the relatives have a lack of information regarding the daily activities of patients under psychiatric treatment. The social networks or the virtual communities regarding health problems do not provide a private space where relatives can follow the patient's progress, despite being in different places. The goal of the study was to use technologies to develop a private social network for being used by severe mental patients (mainly schizophrenic patients). SocialNet is a pioneer social network in the health sector because it provides a social interaction context restricted to persons authorized by the patient or his/her legal guardian in such a way that they can track his/her daily activity. Each patient has a private area only accessible to authorized persons and their caregivers, where they can share pictures, videos or texts regarding his/her progress. A preliminary study of usability of the system has been made for increasing the usefulness and usability of SocialNet. SocialNet is the first system for promoting personal interactions among formal caregivers, family, close friends and patient, promoting the recovery of schizophrenic patients. Future studies should study the network’s potential usefulness for improving the prognosis and recovery of schizophrenia.Item An App to Support Yoga Teachers to Implement a Yoga-Based Approach to Promote Wellbeing Among Young People: Usability Study(Springer Nature, 2019-07-26) García-Holgado, A.; Tajes Reiris, I.; Kearney, N. A.; Martinus, C.; García-Peñalvo, F. J.Many young people suffer from chronic stress and other issues that inhibit the functioning and development of the prefrontal cortex, and this also affects their intrinsic motivation to engage in any activity. In short, unless their well-being is addressed, they cannot engage effectively. The HIPPOCAMPUS project aims to address these issues by promoting the well-being of young people through the practice of a range of techniques derived from yoga. Yuva Yoga app is part of the approach to support the yoga-based practices with young people. It is a multiplatform mobile app developed as Backend as a Service both for Android and iOS. The first public version of the mobile app is part of the pilots implemented in the schools involved in the project, but there is not a special focus on the usability of the app. This work presents the heuristic evaluation of Yuva Yoga for iOS carried out by four experts as part of a major usability study that combines heuristic techniques, both iOS and Android, and empirical methods with users. Some problems were detected during the evalu-ation, but more of the problems have a low priority rating. They are mainly cosmetic problems that do not need to be fixed unless extra time is available on the project, or minor usability problems. The results have provided an important input to develop a new minor version of the mobile app, in order to improve the user experience in the pilots at schools.
