They make the collection and use of personal data quite invisible. In the current scenario, this data collection can introduce risks, manipulate and influence the decision making process. This research is based on concepts from an emerging field of study called Human Data Interaction (HDI), which proposes to include the human at the center of the data stream, providing mechanisms for citizens to interact explicitly with the collected data. We explored the explanation as a promising mechanism for transparency in automated systems. In the first step, we apply the Semiotic Inspection Method (SIM) longitudinally to investigate how using explanations as an interactive feature can help or prevent users from making privacy decisions on Google services. In the second step, we conducted an empirical study in which users are able to analyze whether these explanations are satisfactory and feel (un) secure in the decision making process. And by comparing the results of the two steps, we find that even in a large company like Google, the right to explanation is not guaranteed. Google does not make its data processing transparent to users, nor does it provide satisfactory explanations of how its services use individual data. Consequently, the lack of coherent, detailed and transparent explanations hamper users to make good and safe decisions.","PeriodicalId":237718,"journal":{"name":"Proceedings of the 18th Brazilian Symposium on Human Factors in Computing Systems","volume":"83 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":"116046119","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}

However, not all people can have full access to web-based services and content due to many websites being inaccessible to disabled people, such as people with visual disabilities. In this context, even though developers may demonstrate effort to attempt to create more accessible content, there is limited information about the characteristics of different web accessibility evaluation methods. Thus, the aim of the present study was to perform a meta-analysis of 38 types of accessibility problems on websites extracted from 19 studies in the literature. The studies performed automated assessments using tools, expert-based inspections and user tests involving disabled people. The results confirm other considerations made in the literature, showing that automated assessment methods have significant limitations in the adequate coverage of accessibility problems, covering less than 40% of the types of problems encountered. This way, the paper concludes by showing a consolidation of data from the literature to reinforce claims that effective web accessibility evaluations should count on expert-based inspections and user evaluations involving disabled users.","PeriodicalId":237718,"journal":{"name":"Proceedings of the 18th Brazilian Symposium on Human Factors in Computing Systems","volume":"13 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":"123646387","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}

Transforming a \"thing\" into a network node of a system that makes sense in people's environment has been a challenge for the Human-Computer Interaction (IHC) discipline. In this paper we investigate and propose a Socially Aware Design (SAwD) based process for building scenarios of ubiquitous and pervasive interaction with contemporary technology, including Internet of Things (IoT) scenarios. The starting point for SAwD is understanding the problem from stakeholders' engagement to evolve a design solution together. As part of the process, a solution proposal was created, implemented and iteratively tested with some of the stakeholders under the eyes of researchers. Three iterative cycles were held in workshops with children in a hospital setting that included the observation of researchers, discussions and proposals for the evolution of the solution. At each iteration in the process the importance of people in the technological environment was highlighted, emphasized by the intertwining of technology in the activities developed in each scenario built. The evolution of the system shows that the application of SAwD from its basic premise, which is to understand the problem with the stakeholders that act as the solution's co-designers, was fundamental in the process. Study results show the effectiveness of the proposed process and suggest recommendations for the design of Internet of Human Things (IoHT).","PeriodicalId":237718,"journal":{"name":"Proceedings of the 18th Brazilian Symposium on Human Factors in Computing Systems","volume":"21 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":"127300116","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}

Computer Vision-based AAC systems can support users with motor difficulties by tracking and recognizing their remaining functional motions. To investigate possibilities for people with motor and speech impairments, this paper presents the PGCA: a Computer Vision system that allows the creation of a personalized gestural interaction as assistive technology for communication purposes. PGCA system takes into account the motor abilities and limitations of its users and the knowledge of caregivers in recognizing the gestures performed by the users. Results from interviews with special education professionals and from an experiment with the target audience suggest the use of personalized gestures is a common practice for AAC, and that creating custom datasets can be challenging, mainly due to the level of understanding of participants, the similarity between gestures, and variations in performing the same gestures. Improvements for the system were identified and described aiming to make the interface easier and more effective.","PeriodicalId":237718,"journal":{"name":"Proceedings of the 18th Brazilian Symposium on Human Factors in Computing Systems","volume":"18 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":"121193612","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}

A eventual diferença de qualidade de desempenho dos assistentes em virtude das formas específicas da fala de diferentes grupos de pessoas nos países em desenvolvimento pode ser considerado um viés, bem como um fator que discriminará principalmente os grupos mais vulneráveis e, consequentemente, aumentará a lacuna digital nestes países. Neste trabalho, apresentamos um estudo de caso que analisa a presença de viés na interação por voz com os assistentes, ou seja, uma diferença na qualidade do desempenho dadas características específicas de fala dos usuários. Avaliamos o comportamento do Google Assistente e da Siri para grupos de pessoas distribuídas por gênero e região do país, avaliando duas características da linguagem: a cacoépia e a disfluência. Resultados preliminares indicam que a cacoépia e a disfluência estão relacionadas com a região de origem do falante e têm impacto no desempenho dos assistentes de voz.","PeriodicalId":237718,"journal":{"name":"Proceedings of the 18th Brazilian Symposium on Human Factors in Computing Systems","volume":"96 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":"122883955","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}
