Although live streams for entertainment are the most popular kind, there are also knowledge sharing live streams (KSLS). Embrapa, a Brazilian public agricultural research company, uses this kind of tool to disseminate its research results to the public, which is distributed in an extensive geographic territory. The objective of this work is to make a diagnosis through an online questionnaire with the public of an Embrapa broadcast, identifying their profile and preferences, as well as possibilities for improvements in KSLS. This study's research questions are: Has the live stream proved to be an efficient tool for sharing knowledge? What are the user's preferences? Is it possible to improve their experience? Our results indicate that live streams have great potential for sharing knowledge. In accordance with current studies, we have recognized that great effort is needed to engage the public and there are opportunities to design and develop resources to improve the broadcast environment. In particular, users who participated in our study were interested in annotations and screen recording tools, surveys to influence the offered content, and interactions through multiple-choice questions. We also present some lessons learned regarding preferences, habits, and characteristics of the users.","PeriodicalId":102113,"journal":{"name":"Proceedings of the 19th Brazilian Symposium on Human Factors in Computing Systems","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123655676","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}

Although the literature has addressed the subject, little has been done in the way of exploring how to visualize learning trajectories. In this paper, we present three forms of interactive learning trajectories visualizations linked to the context of computational thinking. As the interactions on visualizations involved different aspects, our proposal comprises three layers: the data representation, the reactions to the navigation and data exploration where more details of the data can be seen. Due to visualizations being tightly related to the context from which the data comes, we analyzed the data types available in Code.org, a well-known platform commonly used to teach computational thinking. To assess the three visualizations, we carried out usability and user experience evaluation with 23 Brazilian elementary schools teachers. The results revealed that the three visualizations achieved an average of 72% of overall understanding by the audience. Besides, our findings showed the visualizations were well accepted among the participants. We also found out that the user experience reported by the participants is in some way associated with the level of understanding of the visualizations.","PeriodicalId":102113,"journal":{"name":"Proceedings of the 19th Brazilian Symposium on Human Factors in Computing Systems","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130880634","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 reports a study that evaluates educational applications developed for children with ASD, focusing on their first experience of use and accessibility aspects related to ASD. The study was conducted in Jaguaruana city and the participants were ten autistic children and their mothers. The first experience of use was monitored and evaluated by observation and questionnaires. Additionally, an accessibility inspection was conducted by three evaluators to identify interface accessibility problems. The results indicate positive aspects concerning the ease of learning to use the applications. On the other hand, our research revealed negative results related to the children's mood changes. We noticed that a child with a higher level of ASD faced more difficulties to maintain attention during the use of applications. In addition, these children demonstrate irritation when failing to perform the challenges. Some improvements can be made in the evaluated applications for a better user experience. Thus, this research contributes to the use of Human-Computer Interaction (HCI) evaluation methods with users and specialists to evaluate educational applications for autistic users.","PeriodicalId":102113,"journal":{"name":"Proceedings of the 19th Brazilian Symposium on Human Factors in Computing Systems","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131024443","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}

During the development process of ICTs for VIP, the concepts of Accessibility, Usability, and User eXperience (UX) are significant because they can positively influence the system's quality. Concerning these concepts, some improvements can be considered already at the design stage, such as screen size, button format, color density, among others. However, not all designers consider Accessibility, Usability, and UX concepts when designing ICT for VIP. To identify and characterize which design technologies of Accessibility, Usability, and UX have been proposed in the literature, we performed a Systematic Mapping Study (SMS). We identified a total of 23 technologies. The analysis from these technologies showed that the majority are destined for mobile applications. Besides, some design technologies only address the concept of Accessibility, and only one technology considered the concepts of Accessibility, Usability, and UX together. To support professionals, students, and researchers in Human-Computer Interaction (HCI) and Software Engineering (SE), this SMS presents a set of Accessibility, Usability, and UX design technologies, which can be used in the initial phases of the ICT development process for VIP.","PeriodicalId":102113,"journal":{"name":"Proceedings of the 19th Brazilian Symposium on Human Factors in Computing Systems","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130692574","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}

They have specific characteristics, such as transparency, attention, calmness, mobility, and context-awareness. Given that the Human-Computer Interaction (HCI) evaluation methods have been proposed for traditional systems, these characteristics present challenges that may require their adaptation. In this paper, we conducted an exploratory study aimed to compare the suitability of Heuristic Evaluation and the MALTU Model to evaluate the Usability and User eXperience (UX) of ubiquitous systems. For this, we apply both methods for evaluating a healthcare system and perform a comparative analysis. From our findings, MALTU is indicated for UX evaluation, being a low-cost approach when compared to Heuristic Evaluation, which is indicated for usability evaluation. Both methods were able to identify the problems that emerge from ubiquity and can provide better results when applied in aggregate. Furthermore, we provide recommendations to apply both methods for the Usability and UX evaluation of ubiquitous systems.","PeriodicalId":102113,"journal":{"name":"Proceedings of the 19th Brazilian Symposium on Human Factors in Computing Systems","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116887055","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 those new interaction possibilities, we discuss in this work elements of crowd engagement through the use of a mobile game developed in the context of entertainment events, either with the crowd in the same place or in different locations. This game is called Bumbometer and it uses movement sensors during an interactive dynamic with the crowd using concepts from Mobile Crowd Sensing and User eXperience. Bumbometer was evaluated in two experimental studies: the first one was in a real setting of a cultural event; the second one was carried out in a controlled environment simulating a large-scale event in a social isolation scenario. Results indicate that people feel immerse and engaged during interaction through the game and they consider the game an immersive creative way for interacting in entertainment events.","PeriodicalId":102113,"journal":{"name":"Proceedings of the 19th Brazilian Symposium on Human Factors in Computing Systems","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128634979","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}
