For the actions that can be proposed, it is necessary to be well acquainted of the needs of this target audience in terms of communication, language and interface design. The aim of this study was then to evaluate the communicability of the Virtual UFMG interface, customized in Virtual Learning Environment (VLE) Moodle, using the Semiotic Inspection Intermediated Method (SUM). The application of this method revealed the main communication problems in the Virtual UFMG interface, apprehended the special needs of the deaf in both situations, in the DE context and the VLE Moodle environments. The results from this application also showed the relevant categories of the system's use and also proposed suggestions for the interface improvement. It was then possible to generate indicators on accessibility in distance education written in Portuguese and focused on deaf users, contributing to their accessibility to DE contexts of academic studies.","PeriodicalId":423409,"journal":{"name":"Proceedings of the 14th Brazilian Symposium on Human Factors in Computing Systems","volume":"149 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":"117295335","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 analyzed the metadata of all full papers published in IHC, the CV of the most prolific authors (i.e. the 105 authors who had more than one paper at IHC), and elaborated a survey to collect data regarding researchers' migration. In this paper, we analyze how researchers have migrated from their institutions of origin to obtain their advanced degrees elsewhere, and how many have come back and some have moved to yet another institution following work opportunities. This migration has shaped collaboration and fostered emerging HCI research groups in diverse institutions, contributing to the diffusion of HCI research throughout Brazil. This paper provides a big picture of the community and a historic perspective on how we got here.","PeriodicalId":423409,"journal":{"name":"Proceedings of the 14th Brazilian Symposium on Human Factors in Computing Systems","volume":"48 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":"128957567","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}

In this sense, choosing the appropriate color for user interface design may cause specific emotions, improving human-computer interaction. However, current studies do not support the designer in the choice of appropriate colors when it comes to a spectrum of emotions. Thus, this article proposes Bianchi's Color Wheel, which combines colors to Scherer's Semantic Space of Emotion. This association is the result of a systematic review conducted in seven databases. The proposed wheel allows designers to choose colors, including variations in saturation and brightness, taking into account the emotions mapped in Semantic Space.","PeriodicalId":423409,"journal":{"name":"Proceedings of the 14th Brazilian Symposium on Human Factors in Computing Systems","volume":"51 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132934621","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}

Considering the above aspects - the use of mobile devices and the inclusion of elderly users in social networks - the objective of this paper is to present the results of an exploratory study on the interaction of elderly users in the Facebook on mobile devices in Brazil, defining the personas that represent these users. For this, two methods were performed: a survey with 271 potential users that provided the data to delineate 3 personas, and a participatory design to verify if the real users, who represent the personas, had different characteristics when compared to the proposed personas.","PeriodicalId":423409,"journal":{"name":"Proceedings of the 14th Brazilian Symposium on Human Factors in Computing Systems","volume":"114 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":"127105469","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 widely used strategy to evaluate usability is known as User Observation and aims to analyze whether the interaction capability provided by the software is appropriated or not. Techniques, such as, Verbalization is widely used to support the evaluations based on observations due to the reason that it provides data about the quality of user interaction. In order to automate the usability evaluation test and to minimize the evaluation time, we developed a tool named ErgoSV, which is based on the verbalization technique and is capable of automatically recognize words defined in a keyword list. ErgoSV also collects, analyzes and provides relevant information about the usability test, such as: a list of pronounced words, pronounced words counter, interfaces (set of screens / video) spoken at the moment of the pronunciation and the exact time moment of pronunciation. Some usability evaluations were conducted with applications from diverse domains and showed the effectiveness of utilizing keywords to perform usability evaluation based on verbalization technique.","PeriodicalId":423409,"journal":{"name":"Proceedings of the 14th Brazilian Symposium on Human Factors in Computing Systems","volume":"27 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":"126083711","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 propose a system to enable students to conduct preparatory pre-class activities using WhatsApp with text commands and multimedia messages.
