It is important that the usability is carefully designed during the system design steps and later propagated to the interface. This care avoids reworking the interface design of an application in the future because of its usability. However, we did not find works that specifically addresses the modeling of interfaces in conjunction with usability. The Interaction Flow Modeling Language (IFML) is a proposal that supports the modeling of the interface. This work investigates the following research question: \"usability in IFML models is perceived and propagated to the final interface?\" In order to answer this research question, we performed an empirical study to evaluate how usability is perceived by participants through IFML models and if usability is propagated to an interface prototype. The study showed that not all aspects of usability are easily perceived and propagated in the interface through IFML models.","PeriodicalId":314561,"journal":{"name":"Proceedings of the 17th Brazilian Symposium on Human Factors in Computing Systems","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126380461","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 relates the development of a simulator that acts in an Virtual Reality environment to present a glycolytic chain and its interactions between the process substrates, allowing the users to interact, through a Virtual Reality Headset and controllers, the molecular compounds and analyze essential chemical reactions to the cellular respiration process.

However, some tasks are not completed mainly because task subjects are not compatible to user capabilities. This article presents a context-aware approach to improve the task distribution in crowdsourcing systems. In this approach, tasks are selected to each worker according to the contexts previously defined. We developed a conceptual task model which uses sensitive information to select participants accordingly to task's contextual requirements and an architecture that illustrates the distribution of tasks through a mobile application. We also presented Contask, a prototype based on the developed architecture, which was used in a study case for evaluating task distribution. The accuracy of the distribution had a result of 63%, followed by 73% of precision and 63% of revocation. These results may be related to the ubiquity characteristic of context-aware computing since the system automatically adapts to user needs and preferences.","PeriodicalId":314561,"journal":{"name":"Proceedings of the 17th Brazilian Symposium on Human Factors in Computing Systems","volume":"48 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131376553","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}

Because voters can vote from any connected place and there is no voting booth to protect them while voting, coercers can easily force them to select their candidates. Although there is no optimal solution for this problem, modern Internet election systems can mitigate it. In other words, these system usually allow voters under coercion to deceive adversaries by casting fake votes. When in safe, voters can vote again; this time, for their legitimate candidates. This idea helps voters to fight coercive attacks. However, these systems require additional actions from the voters that may have problems to perform them correctly. In particular, voters under coercion can have problems to defeat coercive attacks by means of fake votes. In this work, we investigate usability issues with regards the voter action when interacting with coercion-resistant election systems. In order to accomplish this and trying to balance usability and security, we performed a set of usability tests using one of these systems as a case study. This system is based on one of the most efficients cryptographic protocols available. Our results show usability problems that might appear when using these systems in realistic elections. In addition, we present recommendations that can help to design more user friendly coercion-resistant systems.","PeriodicalId":314561,"journal":{"name":"Proceedings of the 17th Brazilian Symposium on Human Factors in Computing Systems","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130558358","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}

Some of these systems are not only for use, but offer possibilities for customization through programming by children. However, especially for small children (4 to 6 years), this universe of differentiated interactions, where different intelligent devices with particular specifications coexist, may require greater cognitive effort, making it difficult to use programming functionalities. In this scenario, this article proposes a model of interaction to guide the offer of programming devices for children. For the construction of this model, Participatory Design techniques were used with 30 children, in order to understand how they would like to program different devices. From the solutions created by the children, the interaction model was specified and represented in the Stamper's Semiotic Ladder.","PeriodicalId":314561,"journal":{"name":"Proceedings of the 17th Brazilian Symposium on Human Factors in Computing Systems","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131214580","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 conducted this research in four steps. First, we executed an evaluation in a perspective of Human-Computer Interaction (HCI) experts, which aimed to analyze whether the features offered by Facebook are adequate to user experience (UX) and sociability guidelines. Next, we performed an evaluation from the elderly users' perspective, in order to investigate users' experience while they are interacting through Facebook. Finally, we made a triangulation of the results and we discussed the impact of Facebook in the social interaction of users. The results showed that the interface and interaction model of Facebook reflects directly on the experience of use and sociability of this members' group.

In this context, the relevant quality property to be considered is communicability. Currently, there are two consolidated methods to evaluate the communicability of a system, Communicability Evaluation Method (CEM) and Semiotic Inspection Method (SIM). In this work, our purpose is to formally present the Intermediate Semiotic Inspection Method - ISIM, as a method to evaluate communicability. The ISIM was proposed to allow for the communicability evaluation from the perspective of indirect users. It was described within the context of educational systems, in a case study to analyze the professor's perspective on systems aimed at their students. However, ISIM has been more broadly used in different contexts, and with different participants. In this article our goal is to formally present ISIM, describing the necessary steps to its application. We also present an analysis of the studies that have applied the method. Based on our analysis we discuss how consolidated the ISIM is, and the different aspects it can evaluate in comparison to SIM and CEM.","PeriodicalId":314561,"journal":{"name":"Proceedings of the 17th Brazilian Symposium on Human Factors in Computing Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116421790","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}

On this way, privacy can be considered one of the determining factors of quality of use, because privacy discrepant interfaces can negatively influence the user's interaction with these systems. One way to support privacy assessment to detect potential problems is through inspection methods. Based on that, in this paper we present a set of privacy inspection techniques called PIT-OSN (Privacy Inspection Technique for Online Social Network). We also present the evaluation of PIT-OSN through of a preliminary study. The results indicated that the technique helped inspectors, not experts, to diagnose privacy issues effectively. PIT-OSN was also considered easy to use and useful by study participants. Finally, the qualitative analysis points out valuable inputs for the refinement of the technique and the opportunities for its improvement.","PeriodicalId":314561,"journal":{"name":"Proceedings of the 17th Brazilian Symposium on Human Factors in Computing Systems","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129634762","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}
