Item Acesso aberto (Open Access) Quimivox mobile 2.0: desenvolvimento de ferramenta no ensino da tabela periódica e distribuição eletrônica aos deficientes visuais utilizando dispositivos móveis(Universidade Federal do Pará, 2019-05-23) OLIVEIRA, Alex Santos de; FERREIRA, João Elias Vidueira; http://lattes.cnpq.br/8018691254585785; MERLIN, Bruno; http://lattes.cnpq.br/7336467549495208Technological advancement has helped the integration of the visually impaired by increasing access to education. This paper presents a proposal to update the application Quimivox Mobile, developed for Android devices, which presents a tool accessible to the visually impaired, giving access to periodic table of chemical elements via synthesis of Voice and commanded by global gestures that do not require pointing to specific elements of the interface. In order to enable vident/visually impaired collaboration, the application also provides visual returns. In addition to the numerical and organizational information provided by the periodic table, the Quimivox Mobile provides several explanatory and qualitative information regarding the: family, period, classification and main uses of the element. The application also adds accessible information about the distribution of electrons in layers and energy sublevels, based on the Linus Pauling diagram and analyzing the data obtained through the evaluation of the application. Consequently, the visually impaired may have greater autonomy in the study of the periodic table and the electronic distribution of the chemical elements when using the new application. Thus, a better teaching and learning of chemistry becomes possible, with equality in the use of technologies with accessibility techniques using mobile devices with touch screen and open source operating system.Item Acesso aberto (Open Access) T-Tátil: desenvolvimento de uma tecnologia assistiva para auxiliar pessoas com deficiência visual na leitura e interpretação de desenhos táteis(Universidade Federal do Pará, 2019-12-12) ZAMPROGNO, Leonardo Zani; FERREIRA, João Elias Vidueira; http://lattes.cnpq.br/8018691254585785; MERLIN, Bruno; http://lattes.cnpq.br/7336467549495208Graphic content, including images, drawings, schematics and maps, is effective in providing a considerable amount of information concentrated in a small space, allowing a better organization of data and information series so that they are easily understood. They are widely used in the teaching process at all levels of education. Naturally, visually impaired people do not have easy access to such contents. Other strategies are used by visually impaired people to access graphic contents, one of them is the use of tactile drawings that enable to explore graphic representations using the sensory touch system for this task. However, it is difficult for visually impaired people to be autonomous in reading and exploring tactile drawings usually needs the help of a sighted person to provide initial information, such as the general message conveyed by the tactile drawing, and to guide the individual in step-by-step reading. The absence of such a person may make it impossible or considerably difficult for visually impaired people to use tactile drawings. Assistive technologies have been developed to make it easier for visually impaired people to access graphic data and even to make displays more dynamic. In this paper we list some of the main assistive technologies that aim at helping visually impaired people to read and interpret tactile graphs using various forms of feedback for vision substitute sensory systems. After studying different strategies for exploring tactile designs adopted by visually impaired people, we proposed to develop an application for ordinary tablets exploring the benefit of multimodal interactions by overlaying tactile designs printed on touchscreens intended to assist the visually impaired people in reading tactile drawings. After confirming that interactions with current touchscreens devices are possible through the papers used to explore tactile designs superimposed on the screen. In a case of study, the application prototype was tested with three blind students demonstrating that the solution has a promising approach to improve exploration of tactile designs. It also raised improvement requirements. After the implementation of these improvements, a controlled experiment with 8 blind participants was performed to compare the exploration of tactile designs with braille subtitles with multimodal tactile designs, using the developed application, and to evaluate the application usability through a SUS (System Usability Scale) questionnaire. The results showed that the application has excellent usability, according to the participants, and that the task of tactile exploration is more enjoyable, easier and faster with multimodal tactile designs, demonstrating also a performance gain and improved understanding of tactile design, and at last that user satisfaction was higher when using the application.Item Acesso aberto (Open Access) Tecnologia assistiva para auxiliar o ensino de genética clássica a deficientes visuais: um estudo de caso na região amazônica(Universidade Federal do Pará, 2020-07-10) OLIVEIRA, Mônica Silva de; MERLIN, Bruno; http://lattes.cnpq.br/7336467549495208; VERAS, Adonney Allan de Oliveira; http://lattes.cnpq.br/2201652617167877; https://orcid.org/0000-0002-7227-0590Assistive Technologies has contributed significantly to the inclusion process, encompassing solutions that contribute to the dynamic and gradual construction of the teaching-learning process. It is possible to realize over the years the development of many computational solutions in this area for the visually impaired. However, there is also a strong need for productions in specific areas, such as Genetics, a subarea of Biological Sciences, still little explored. Analyzing this gap, the work in question proposes to make use of mobile devices as a facilitating tool in the inclusion process, through the development of an assistance application to assist in the teaching of classical genetics to students with visual impairments in the regular classroom. Allied to the mobile application, a web platform is proposed to promote and facilitate the interaction between students and professors of the discipline. Based on the survey of requirements and usability tests, through the SUS Usability Scale, the application interface was developed, according to meet the needs of the users. This study was carried out in the city of Tucuruí, the southeastern region of Pará. The results obtained in relation to the use of the application by the participants, show a high level of satisfaction (80%), also allowing it to be used by the visually impaired student to study inside and outside the school environment.
