With this popularity, one of the concerns of Human Computer Interaction area (HCI) is how to motivate users through the interface and interaction model, to make the continued use of these applications. Consequently, new design strategies have been explored to meet the needs of these users. In this sense, the adoption of gamification strategies has contributed positively to the continued use of mobile applications in the educational domain. Motivated by this scenario, this study aims to evaluate and characterize as Duolingo application, considered one of the best applications for teaching languages, has adopted the gamification strategies and, in fact, these strategies contribute as a motivational factor for application use. The results obtained allowed to observe how the strategies adopted by the designer interface have helped to motivate the continued use of this application and, complementarily, may assist in developing and evaluation of applications that make use of gamification as a motivational factor.","PeriodicalId":423409,"journal":{"name":"Proceedings of the 14th Brazilian Symposium on Human Factors in Computing Systems","volume":"9 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":"114065781","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}

Empirical methods are often applied to assess emotional responses evoked from a user interface, but the cost of data collection and analysis is generally high. The adoption of analytical methods is an alternative to the high cost. Although the analytical methods, such as usability, accessibility, and communicability, are widely accepted in the HCI area, there is a lack of evaluation through emotional response. Semiotics is a way to understand what the elements of an interface represent for the user. This paper proposes a method based on semiotics for evaluation of possible emotional responses evoked by presented elements on the interface. This method was applied in a case study and the results were considered consistent when compared to those achieved by empirical methods.","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":"115310782","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}

Physical prototyping of this newly created device features movement recognition and sensory feedback as modalities of interaction. In usability tests, data was collected on users' performance and satisfaction, as well as data on their cognitive load (attention) and state of meditation (relaxation) captured through an Electroencephalogram device. The results showed that the prototyped solution, analyzed for a sample of 18 users, increased performance in typing long texts in 26.5%, raised satisfaction scores by 15% and relaxation scores by 29.4%, and maintained the users' cognitive load compared to use of an infrared remote control.","PeriodicalId":423409,"journal":{"name":"Proceedings of the 14th Brazilian Symposium on Human Factors in Computing Systems","volume":"35 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":"128739845","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}

Designers of these systems must define the possible customizations to be offered to users at design time. To do so, they have to decide what choices to make available to users, and consider which scenarios may be generated by users' decisions and their impact over time in other users' interactions. In this paper, we propose a modeling language that supports designers in this activity by allowing them to describe users' choices and actions over time and their impacts. Based on this description a scenario generator describes the situations that users can create by their choices. Exploring the scenarios generated at design time, the designer can inspect if any of the scenarios represent undesirable situations for end users. A preliminary evaluation of the model is presented and discussed.","PeriodicalId":423409,"journal":{"name":"Proceedings of the 14th Brazilian Symposium on Human Factors in Computing Systems","volume":"1 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":"130901093","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 focuses on how concurrency is dealt with by five well-known tools in this domain: Scratch, Alice, AgentSheets, NetLogo and Greenfoot. We present the results of a systematic analysis contrasting their model of concurrent behavior with the corresponding programming interface messages that trigger their users' interpretation and learning of concurrency-related concepts. We present and discuss the conceptualizations that potentially emerge from using these five tools and compare them with established concurrency concepts. Our findings indicate opportunities for an explicit exploration of how some concurrency aspects are implemented in games and simulations built with CT tools. We believe that this might facilitate future learning and comprehension of complex concurrency concepts, considering that the knowledge embedded in these tools can also influence students' understanding of concurrency.","PeriodicalId":423409,"journal":{"name":"Proceedings of the 14th Brazilian Symposium on Human Factors in Computing Systems","volume":"1 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":"129991999","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}
