The literature has indicated that a cognitive authority produces and shares information of better quality and relevance for those who recognizes that authority, being a promising concept to support information retrieval and quality judgement on the web. However, identifying such authorities is still a challenge. In this paper, we introduce the idAuthority: a conceptual framework to support the identification of cognitive authorities in social networks. To illustrate its application in a practical context, we instantiate the framework for a real online social network of Inclusive Education teachers, and evaluate its results with a group of six teachers. The results indicate the idAuthority as a promising framework to support the creation of mechanisms for identifying cognitive authorities in specific social networks.","PeriodicalId":423409,"journal":{"name":"Proceedings of the 14th Brazilian Symposium on Human Factors in Computing Systems","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133418286","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 present the Privacy Design Model (PDM) - built upon Altman's theory of privacy and Semiotic Engineering theory - as a descriptive model that takes into account dimensions corresponding to aspects upon which designers should reflect at design time, regarding personal information disclosure within these systems. PDM considers as personal information disclosure not only pieces of information about the individual, but also the individual's speech and activities that express his/her identity within the system. Thus, we hope to provide designers with a better understanding of how privacy can be treated in SNS by structuring the design space of personal information disclosure through such dimensions. We also analyze the applicability of the model, through the deconstruction of a real SNS in terms of the privacy dimensions proposed in PDM and discuss the implications of our findings.","PeriodicalId":423409,"journal":{"name":"Proceedings of the 14th Brazilian Symposium on Human Factors in Computing Systems","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128031441","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, as the 4th Grand Research Challenge for the Brazilian Computer Society mentions, it is necessary to extend computational systems to all Brazilians, respecting their diversity and differences. Most studies in the literature consider the participation of users with different profiles during the design process. However, there is not a concern with interface adaptation to user's needs and interaction preferences. This paper presents a design process which guides the ubiquitous systems design from the relevant users' features identification to adapt the user interface, to the evaluation of the created prototype. The user's characteristics identification is performed by applying the UbiCARD technique in the system context to be developed. A prototype is presented as a proof of concept.","PeriodicalId":423409,"journal":{"name":"Proceedings of the 14th Brazilian Symposium on Human Factors in Computing Systems","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114270797","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}

Our principle, as many other possible approaches, is that interaction design is an iterative and interactive process for developing systems in which the Participatory Design (PD) and User Centered Design (UCD) is essential, providing creation of end artifacts to better satisfy user's needs, incorporating their abilities, not only for work perspective but also in other aspects of their lives. From our study we've formalized our observations into design guidelines so that the out-office user's experiences, incorporating concepts of their daily life and social activities become part of the design requirements, what is essential to the system to achieve the necessary properties for ICT adoption.","PeriodicalId":423409,"journal":{"name":"Proceedings of the 14th Brazilian Symposium on Human Factors in Computing Systems","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124090990","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}

For people with severe motor disabilities, gaze is one of the few alternatives to interact with the world. The most common gaze interaction paradigm is called dwell-time, where keys are selected using fixations longer than a certain \"dwell\". Though simple, this mechanism does not permit the selection of keys at precise moments, a requirement to play music and certain video games. In this paper we introduce two gaze interaction techniques that overcome this limitation. The first is an extension of the dwell-time, where selection is triggered when the gaze exits the focused key. The second is based on the Context Switching paradigm, that uses saccades for selection instead of fixations. Results of a user experiment show that the Context Switching paradigm permits a more accurate timing control while playing music at 45 and 70 beats per minute.","PeriodicalId":423409,"journal":{"name":"Proceedings of the 14th Brazilian Symposium on Human Factors in Computing Systems","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121139382","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 paper presents the design and construction of a TUI environment to be used in inclusive educational contexts, allowing children to create, share and participate in the process of constructing narratives. The environment was conceived under the Semio-Participatory Design Model, and was experimented with the active participation of teachers and children in a real educational context.

In this article we investigate the influence of Facebook's interface on how its users share information. To do so, firstly we present a comparison of how users share their information online and offline. We also analyze Facebook and identify which strategies are used in the system to allow or encourage users to disclose their information. By contrasting the pieces of information that are shared with a larger audience online than offline with which pieces of information the interface gives a bigger encouragement to users to disclose we find that there is a large overlap between the two groups. This finding points to the potential impact that interface decisions have on users' self-disclosure on social networks.","PeriodicalId":423409,"journal":{"name":"Proceedings of the 14th Brazilian Symposium on Human Factors in Computing Systems","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121827835","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}
