It is necessary to plan how these perspectives will be designed, in order to avoid that problems in the use affect the wide adoption of the systems. In order to support the design of these perspectives, it was proposed in recent research in the HCI area, a notation that allows the elaboration of models representing design solutions that can express aspects of usability during interaction and navigation, called USINN (USability-oriented INteraction and Navigation model). However, the notation did not yet have a specific tool to support the development of these models. The absence of a tool made the use of notation laborious and susceptible to syntax errors in the models. This paper presents the preliminary results of the design and evaluation of a tool for modeling interaction and navigation with the USINN notation: the USINN Modeler tool, an open source tool developed for the web. The initial results indicated that the tool facilitates the construction of the models and contributes strongly to the use of the notation.","PeriodicalId":237718,"journal":{"name":"Proceedings of the 18th Brazilian Symposium on Human Factors in Computing Systems","volume":"49 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":"125941627","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}

The ethnographic data collected is used as supporting material in the design of a memory game that uses Near Field Communication (NFC) technology. We conducted a Case Study to evaluate the memory game with the participation of 5-6 years old children and preschool teachers, in a real educational scenario. The results suggest that NFC technology may enhance the play experience of the classic memory game by providing emotional connections with the children.

The application was redesigned in order to improve accessibility for the visually impaired (blind and low vision) and meet the difficulties related to color blindness. The interaction is performed on the basis of vocal commands and simple gestures, and the information is provided both graphically and via voice synthesis. Comparative assessments were performed between the two versions of the application, from the second version with usual tools of access to information for psychics, and automated tests to evaluate the resilience to color blindness.

This paper explores current practices about evaluation methodologies for Assistive Technology (AT) interaction devices for people with motor disabilities, both considering the use of computers and TV-sets. To achieve this objective the results from a systematic mapping study about AT evaluation methodology and a field research was done in Portugal with experts in Assistive Technology Evaluation and end users. This field research was done, with a semi-structured interviews and for the data analysis, a content analysis of these interviews was carried out. The findings from this research suggest that there are key dimensions that should be addressed when evaluating AT: qualification issues remain most important, especially the developers' awareness of end user needs as barrier on computer access. Other important issues are economic barriers involved in the acquisition of AT interaction devices as well as the emotional issues involved in using these devices. Finally, the paper concludes with a discussion on directions for evaluation methodologies of AT interaction 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":"124695762","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}

One such limitation is related to limited reading of mathematical expressions by screen reading software. With the technological advances, the use of assistive technologies by these people became fundamental for the educational process. However, this technology still has gaps in the ability to read complex expressions and language support, especially in the Brazilian context. Thus, the present study presents usability tests involving visually disabled users on a prototype of screen reading software with reading of mathematical formulae in Brazilian Portuguese and intra-formulae navigation features, named ChromeVox-NavMatBR system. The tests involved 12 users. The evaluations involved the assessmenet of features related to navigation, reading and comprehension of mathematical expressions. Finally, quantitative and qualitative data were collected regarding the use of the system. The study encountered problems related to prosody aspects in formulae reading, response time, comprehension of specific technical terms, and reading of complex mathematical elements.

Privacy expectations in OSNs are getting smaller as more members begin to face potential privacy problems when interacting with these systems. Inspections methods can be an effective alternative for addressing privacy problems because they allow detecting a possible defect that could be causing the system to behave in an undesirable way. Based on that, a set of privacy inspection techniques called PIT-OSN (Privacy Inspection Techniques for Online Social Network) was proposed. This paper focuses on one of these techniques (the PIT-OSN 1), which supports the inspection of the privacy levels in an OSN. The goal of this paper is to present the evaluation of PIT-OSN 1, through an empirical study, which collected quantitative and qualitative data. Results obtained from the analysis indicate that the technique assists nonexpert inspectors detecting privacy problems effectively and that it was considered easy to use and useful by the participants of the study. Finally, the qualitative analysis points out relevant improvement opportunities in PIT-OSN 1.","PeriodicalId":237718,"journal":{"name":"Proceedings of the 18th Brazilian Symposium on Human Factors in Computing Systems","volume":"46 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":"127028418","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}

Unfortunately, many studies have shown that even popular mobile applications still have many accessibility issues. A particular characteristic of mobile development is that developers tend to take into account comments published on official app stores to plan for new releases of their apps. Some researchers have classified user reviews into different categories, including user interface issues, but none of them have investigated whether accessibility is a topic addressed by user comments. Therefore, the purpose of this paper is to present an investigation we carried out to find out whether and how accessible is addressed by user reviews published on app stores. In our investigation, we analysed 701 Android apps available on the Google Play Store and found out that reviews associated with accessibility are scarce (1.2% of all reviews); user reviews usually refer to a small subset of accessibility issues; and users give reasonable good scores to mobile apps even when they report accessibility issues, with the exception of very specific cases. It seems our results show that user reviews have not been used to suggest developers to improve mobile apps accessibility.","PeriodicalId":237718,"journal":{"name":"Proceedings of the 18th Brazilian Symposium on Human Factors in Computing Systems","volume":"27 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":"134574954","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}
