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.","PeriodicalId":237718,"journal":{"name":"Proceedings of the 18th Brazilian Symposium on Human Factors in Computing Systems","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123344566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This issue is even more sensitive when considered under the perspective of people with visual impairments, who depend on operating systems (OS) accessibility features. However, native OS accessibility support is not mature enough to ensure usability and accessibility simultaneously in different kinds of applications. To overcome these limitations, Human-Computer Interaction literature has been proposing guidelines, best practices, and heuristics for designing and evaluating usable and accessible designs. Still, this information is diffuse and can be challenging to implement because they were proposed considering different definitions and specifications. To support practitioners, students and researchers in finding and implementing usability and accessibility guidelines in mobile applications, the present work presents a compilation of 369 recommendations identified in the literature on the design and evaluation of usable and accessible interfaces for blind people on mobile devices.","PeriodicalId":237718,"journal":{"name":"Proceedings of the 18th Brazilian Symposium on Human Factors in Computing Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130063560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tests such as usability can be employed to contribute to their quality. In such cases, it is possible for evaluators to analyze interfaces and note which usability errors should be corrected. Also, according to the belief of self-efficacy, those who think they are more experienced should find more errors. In this context, the purpose of this study was to perform a usability test with evaluators to verify if those considered to be more experienced were able to find more errors. A self-assessment form and a usability test were applied for this purpose. For each of the nine participants, their experience information along with the usability errors encountered by them were collected. As a result, those who thought they were capable of finding most of the errors did not match those they encountered.","PeriodicalId":237718,"journal":{"name":"Proceedings of the 18th Brazilian Symposium on Human Factors in Computing Systems","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122514449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have carried out a Systematic Literature Review and analyzed how MoLIC has been used by the HCI community, considering how it has been used over the years, the number of authors that reference or use it, forums in which works have been published, as well as the main contributions of the research about it. Our results indicate that MoLIC is well consolidated, as it has been broadly used and studied by national and international authors.

In the context of Human-Computer Interaction (HCI) field, the usage of empirical methods plays a vital role due to its focus on evaluating the end-user and usability of software solutions. Even though the adoption of experimental evaluation techniques has gained popularity in recent years, its application is still questioned both qualitatively and quantitatively. Goal: To analyze how empirical research has evolved in the Human-Computer Interaction Brazilian community. Method: We performed a quasi-experiment, using published papers over the 17 editions in Brazilian Symposium on Human Factors in Computing Systems. Our experiment was divided into two phases, in order to evaluate the quality assessment and classify the type of realized empirical study, respectively. Results: From the sample of 231 studies, 113 reached satisfactory quality in the first phase. It was found that empirical studies were becoming more present in lastly years of the conference. Moreover, in the second phase, it was found with 95% confidence that the quality of the empirical studies increased, by comparing two different divisions of the 20-year conference period. Findings: The assessment questionnaire used in our research and the learned lessons about each kind of empirical study can support the conduction of new empirical evaluations in the HCI community, improving their quality.","PeriodicalId":237718,"journal":{"name":"Proceedings of the 18th Brazilian Symposium on Human Factors in Computing Systems","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123907598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
