One subgroup of visual exploration tests, called cancellation tests, require the identification of specific targets surrounded by distractors. However, the lack of automated versions of these tests limit their availability to a larger audience. In the present paper, we present an automated version of a cancellation test: the car test. The test is designed to be used by specialists and to be user-friendly optimizing its application and the analysis of collected data. We evaluated the car test in a group of 6-9 y.o. infants enrolled in a private school. The results suggest the car test is effective in providing information about visual exploration strategies of infants and is in agreement with the results of similar tests found in the literature.","PeriodicalId":314561,"journal":{"name":"Proceedings of the 17th Brazilian Symposium on Human Factors in Computing Systems","volume":"7 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":"115439426","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}

With this in mind, many applications have been developed in order to teach programming concepts to children, such as AgentSheets and Scratch, systems that use a visual programming language to create games and interactive animations. However, there is little research into communication strategies that are used by interactive systems to teach programming to kids. In this paper, we evaluate how both of these applications address cultural aspects that allow a progressive learning of programming concepts. We have found out that both systems address cultural aspects in a similar way. Their focus is to teach how to write programming codes using their visual language, but without gradually introducing programming concepts to the user.","PeriodicalId":314561,"journal":{"name":"Proceedings of the 17th Brazilian Symposium on Human Factors in Computing Systems","volume":"137 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":"116609422","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}

One of the criticisms of this instrument is the emotional impact on students, who feel pressured and nervous at the time of resolving a test. This paper presents a study of the uses and consequences of \"cheat sheets\" in HCI tests. The cheat sheet is a material prepared by the student himself that can be used during the resolution of the test. As a result, the use of the cheat sheet brought at least three positive consequences: a) motivated the students to study before the test; b) made them calmer and more confident during the test time; c) helped them to resolve the questions. In addition, from the point of view of the students, we discuss the strategies of study and organization of the content in the elaborated sheets and, from the point of view of the teacher, we discuss the strategies of elaboration of the tests with cheat sheets.","PeriodicalId":314561,"journal":{"name":"Proceedings of the 17th Brazilian Symposium on Human Factors in Computing Systems","volume":"49 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":"128336657","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 a similar way, viewers can experience a negative experience when subtitles are not well synchronized with the media content. The point is that subtitles synchronization (or the lack thereof) plays a key role, positively or negatively, in the perception of quality that viewers have about the content. In this context, this work focuses on investigating how slightly more \"relaxed\" synchronization directives may affect significantly the perception of Quality of Experience (QoE) that users have when watching audiovisual content in English with subtitles in Brazilian Portuguese. Our observations are based on the analysis of data collected in an experiment with 24 users and the results suggest that subtitles beginning with delay have most influence in the viewers' QoE.","PeriodicalId":314561,"journal":{"name":"Proceedings of the 17th Brazilian Symposium on Human Factors in Computing Systems","volume":"28 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":"125034130","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}

The communication fluency of the user that uses graphic symbols depends on factors like the vocabulary (set of symbols) selected, how accurate the relation between the symbols and their referents is presented, the way how the communication system is shown, and so on. The main goal of this research is to analyse an initial set of graphic symbols proposed in a computational environment which uses tangible technology, through Radio Frequency Identification, to represent communication cards used as a way of Alternative and Augmentative Communication technology. Seven workshops were carried out with tutors, children and researchers in an educational context. The results showed the process of selection by the participants to a initial set of the environment's cards, pointing out those that are representatives and contribute to the communication and suggesting the redesign of others, as well as changes in the tangible environment and its interaction way.","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":"128246169","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 a previous work, a web-based portal called FLOSScoach was proposed to support the first contribution of newcomers to Open Source Software Projects. The preliminary evaluation indicated that FLOSScoach has played an important role in guiding newcomers and in lowering barriers related to the orientation and the contribution process. Gamification has been widely used to engage and motivate people to accomplish tasks and improve their performance. Therefore, the goal of this study is to present the FLOSScoach gamification proposal, which is illustrated in the form of the high-fidelity prototypes as a step to support on the decision of the game elements.

The use of drones as a tele-inspection tool is already a feasible alternative. However, it requires a collaborative interface between pilot and inspector. This work evaluates two wearable interfaces of augmented reality as HCI alternatives to assist the drone pilot in the inspection. The goal is to validate the platforms for visualization of the images of the industrial environment. Thus, user studies were conducted to evaluate the impact of the use of these augmented reality interfaces in the accomplishment of the task.
