However, consider the several different human factors, and also the ubiquitous technologies specificities, in the design process is still a challenge. It is known that many researchers use simulation techniques to smooth the process of ubiquitous systems design and evaluation. However, many of these simulation techniques have failed to cover the different users' needs and support the development of flexible user interfaces. In order to overcome this limitation, this paper proposes an approach to simulate flexible ubiquitous environments that consider the diversity of users. This new approach was developed from the adaptation of the Wizard of Oz technique. This paper also describes the application of this approach in a simulation of a smart kitchen.","PeriodicalId":345266,"journal":{"name":"Proceedings of the 15th Brazilian Symposium on Human Factors in Computing Systems","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133223350","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}

Semistructured interviews were conducted in order to find out if analysts know and use data visualization, as well how they consider it important. This is work in progress that aims to raise a discussion on understanding the needs of analysts in relation to data visualization. From the data collected, it could be observed that social media data analysts know the concept of data visualization, and they believe that its use could significantly improve the analysis process. Some analysts think tools are complex, and others consider that the available tools do not fully meet their needs.","PeriodicalId":345266,"journal":{"name":"Proceedings of the 15th Brazilian Symposium on Human Factors in Computing Systems","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130921971","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}

These practices sometimes occur in User-Centered Design (UCD) literature, offering a risk of compromising the focus on the user proposed by the UCD theories, by unempowering the users and removing them from the productive process. This paper proposes a method for analysing content of papers on accessibility-related tracks of the latest editions of the Brazillian Symposium on Human Factors in Computer Systems to investigate whether the appropriations of UCD in the publications are unempowering users through a narrative trope called \"Tyrants, Heroes and Victims\", defined by Clay Spinuzzi, or empowering narratives are employed in writing. We expect that this paper will serve as an exposition of the usage, and the risks, of unempowering narratives in the Interaction Design community.","PeriodicalId":345266,"journal":{"name":"Proceedings of the 15th Brazilian Symposium on Human Factors in Computing Systems","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115270269","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}

It has effects in fundamental schools that have become heterogeneous and multicultural environments. In some Brazilian schools are used different kinds of digital technologies that can support teaching and learning processes. According to Semiotic Engineering, digital technologies are product intellectual and cultural of designer.Then, cultural differences between designer and user can influence the quality of interaction. This work has a hypothesis that the active participation of user in the interaction process can contribute to recognize and consider cultural differences in interaction design of educational technologies. This paper presents a semio-participatory framework based on Semiotic Engineering and Participatory Design guidelines for interaction (re)design of educational software. This framework was applied in interaction redesign of an educational software, which allowed users' cultural aspects were highlighted in interaction (re)design process.","PeriodicalId":345266,"journal":{"name":"Proceedings of the 15th Brazilian Symposium on Human Factors in Computing Systems","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122379445","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}

Based on the sociocultural context of affirmation of difference and space-time of cooperation established by Web 2.0, conceptually grounded in the research area of Computer Supported Cooperative Work, this research discusses the potential for cooperation and individual and collective authorship of Groupware tools when interacting with individuals visually impaired. The results of the experiments showed a weakness about the availability of awareness elements targeted to people with visual impairment, including, lack of user identification features in synchronous and asynchronous action and absence of feedback strategies for awareness and among participants.","PeriodicalId":345266,"journal":{"name":"Proceedings of the 15th Brazilian Symposium on Human Factors in Computing Systems","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127963628","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}

Through a quantitative survey, we applied an experiment with ten participants, selected by non-probability sampling, but for convenience. The aim of this study was to evaluate whether menus with gestural interaction must have some form of release mechanism to avoid accidental selections of options by the users. We used task performance measures such as reaction time and number of errors during selection tasks to assess usability. Regarding the user satisfaction, we applied a questionnaire to evaluate the two game versions, with and without a release mechanism. Results showed no significant differences related to user satisfaction and number of selection errors between versions. Conversely, considering reaction time measurements between versions, results revealed significant values.","PeriodicalId":345266,"journal":{"name":"Proceedings of the 15th Brazilian Symposium on Human Factors in Computing Systems","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134300688","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}

Using this template, thirty users have entered all the letters of the alphabet three times each in three groups totaling ninety inserts for each letter. Gestures entered by users have been used to train a Naive Bayes classifier that calculates the probability of insertion for each letter to from the user-entered gestures. During the development work was also carried out a study of the most frequent letters of the Portuguese language. Another partial result of the project is a prototype in which the user enters all the letters of the alphabet using the template gestures. By the time the user enters a gesture prototype automatically suggests the most frequent letters using the Naïve Bayes classifier.","PeriodicalId":345266,"journal":{"name":"Proceedings of the 15th Brazilian Symposium on Human Factors in Computing Systems","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133126908","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}
