Nesse sentido, durante a pandemia de COVID-19, dois fatos chamaram a atenção para a importância de Infovis para Saúde: por um lado, percebeu-se a nítida apropriação das convenções visuais da Infovis pela mídia e consequentemente, pelo cidadão comum, que por força da relevância do contexto, precisou absorver temas como mapas coropléticos, médias móveis e representações logarítmicas. Por outro lado, revelou-se a grande carência de instrumentos adequados para o monitoramento e a tomada de decisão pelos gestores da saúde pública.

Despite the growing number of guidelines, standards, and recommendations for accessibility on mobile devices, there are still accessibility issues in mobile applications. Although guidelines, standards and recommendations contribute to educate developers towards universal design, difficulties in the development process discourage developers implementing accessible applications. In addition to directives, tools are needed to automate the process of integrating accessibility in the applications. Through a systematic review of the literature, this work seeks to identify the state of the art in tools for developers in the creation of native mobile applications accessible to people with visual impairment, characterizing when to use them in the development process and its degree of technological maturity.

Yet, despite the growing number of mobile accessibility studies, compared to website-related studies, there are still few established and well-established techniques and guidelines. As a result, development tools for building accessibility in mobile applications are scarce. They are based primarily on operating systems recommendations and guidelines, such as those provided by Google and Apple and many are useful only after the development effort has been spent. This paper presents AccessibiLint, a tool for static code verification of accessibility rules for Android native applications. AccessibiLint was developed as an extension of Android Lint tool base on a set of guidelines for visually impairment accessibility for native Android applications.

Based on researches about Brazilian cell phone market, we have defined archetypical mobile devices using the persona technique. The resulting group of fictitious models intends to help designers abstract the large number of possible devices. We review W3C (World Wide Web Consortium) mobile best practices as an example of usage of the mobile device personas in design.

Usability evaluation intends to identify difficulties experienced by a user when interacting with a computer interface. Usability evaluation is a key issue in assessing the return from investment in government sites, as it can measure how the services impact the citizen and is a significant source of requirements for design reviews of present services. This paper describes the creation of a Laboratory for Human-Computer Interaction (LabIHC) devoted to assess Sao Paulo State, Brazil, government services usability. This Laboratory evaluates about 250 users per day using different egovernment services and can produce accurate reports on usability problems. The paper describes LabIHC's pluralistic evaluation methodology, composed of four different techniques, as well as the set of recommendations that were derived from LabIHC results for e-government services. e-govemment; usability; universal usability; usability evaluation.

This paper presents an online recommendation system that eases the matching of a user with the most relevant products and services. The designed system consists of three recommendation algorithms; two of them are already widely discussed in the literature, while the third one is new and was proposed to consider the trust relationship between users and their peers. This work also presents an experiment with real users that intends to evaluate the proposed new algorithm in comparison with the other two and also with direct, human-to-human recommendations. The paper presents the results gathered on experimental data analysis and the statistical hypotheses tests that were performed, which allowed concluding in which circumstances trust-based recommendation is advantageous.

Nesse sentido, durante a pandemia de COVID-19, dois fatos chamaram a atenção para a importância de Infovis para Saúde: por um lado, percebeu-se a nítida apropriação das convenções visuais da Infovis pela mídia e consequentemente, pelo cidadão comum, que por força da relevância do contexto, precisou absorver temas como mapas coropléticos, médias móveis e representações logarítmicas. Por outro lado, revelou-se a grande carência de instrumentos adequados para o monitoramento e a tomada de decisão pelos gestores da saúde pública.

Personal data are used by organizations in business and marketing tasks. However, details about personal data usage are often not accessible or clear to data subject, raising concerns about privacy and security. Presentation of information about personal data usage needs improvement towards Personal Data Transparency. Thus, this paper aims to present the TR-Model, a Metadata Application Profile guideline that intends to propose a standardization on information to be considered minimally necessary to Personal Data Transparency as well as a set of specifications to guide developers on how to present this data. TR-Model elements are focused providing Personal Data Transparency in a user-friendly and high quality format. TR-Model presents a set of specification based on entities, metadata, metaevents and descriptions. The model evaluation was based on user testing in several scenarios of usage of personal data in a gym application tool. The information presented was created based on the TR-Model metadata, metaevents and descriptions. Participants evaluated transparency considering dimensions of Human-Computer Interaction and Information Quality. Participants' opinions were recorded in surveys and analyzed with descriptive statistics; the results indicate that the TR-Model was effective in supporting the production of friendly, understandable and relevant Transparency for data subjects, in compliance with regulations like GDPR.
