Summary: This paper presents a comparative analysis based on two independent studies of Human-Computer Interaction (HCI) education and research in Brazil. The first study was conducted to understand how HCI has been taught in Brazil, via a survey responded by 114 educators and researchers in the country. The second study analyzed the scientific production of HCI in Brazil from a fifteen-year analysis of full papers published on the Brazilian Symposium on Human Factors in Computing Systems (IHC). Our analysis is based on data-driven visual exploration, and it can help to get insights from the data and to identify how HCI research in Brazil relates to our education programs. We believe this kind of analysis can shed some light in the evolution of HCI in other countries.

Summary: Nowadays it is notorious the growth and the popularity of social networks such as Facebook, LinkedIn and Twitter, especially with the facilities provided by the use of mobile devices. Considering these social networks, Twitter has a different approach: a friendship connection doesn't need to exist and a person can follow another person or organization just to receive its tweets. So, this social network is often used as a way to get general or specific news and to express (dis)satisfaction about products, politics, organizations, etc. Considering this, the need for organizations to monitor what people are "saying" about them has arisen. Thus, the main goal of this work is to understand how information visualization techniques can support and improve the analysis of the perceived image of organizations on social networks. For this, we developed an application prototype to support sentiment analyses on Twitter and we conducted a study on how this prototype, called MentionStats, can contribute to the company's image analysis on Twitter. This study consisted on interviews with professionals about their perceptions of the MentionStats and its visualizations. Our main contribution are the presented possibilities of using information visualization techniques in order to help users to deepen the analysis of their organizations image on social networks, and also users' impressions about this.

Summary: The relation between HCI Education and the Industry needs is a challenge to the HCI community. HCI professors should be aware of their role to persuade students that user experience and experience design are cross-cutting concepts, which therefore influence all other areas involved in innovative product and service development, from conceptual design to implementation and testing. In this paper we present a revised HCI Brazilian syllabus for undergraduate Computer Science courses, discussing HCI requirements for UX professional and academic formation of the students. We also describe some research questions that have been raised in this context.

[4] What About Document Folding? User Impressions and a Design Approach Interaction Design / Chamun, Rodrigo / Ziesemer, Angelina / Manssour, Isabel H. / de Oliveira, João B. S. / Silveira, Milene S.

Link to Digital Content at Springer

Summary: Designing documents with folds is a difficult task with current desktop publishing software, and this subject is also hardly explored in the academic literature. Because the flat nature of the screen, document design is limited to a two dimensional space, demanding extra effort from designers to place the art with respect to the folds, sometimes forcing them to resort to paper prototyping. Results from interviews performed with design experts, helped us to understand the challenges and needs faced by them during the document creations. This paper presents an interactive visualization approach to compose foldable documents and to interact with the results without resorting to external means. We consider that a foldable document such as brochure is composed by panels joined at the edges and the content of each panel is designed separately. We describe our interactive approach and the results generated by a prototype we developed to support the composition of foldable documents.

[5] Towards an Interactive and Iterative Process to Design Natural Interaction Techniques Design Methods, Techniques and Knowledge / Cossio, Lucio Polese / Lammel, Felipe Eduardo / Silveira, Milene Selbach HCI International 2014: 16th International Conference on HCI: Posters' Extended Abstracts, Part I 2014-06-22 v.4 p.19-23

Link to Digital Content at Springer

Summary: With the rise of different interaction modalities, several different devices are available to users that need to learn how to interact with them. To avoid problems in the future, developers need to create intuitive interaction techniques, which is not a trivial task. To support the design of these techniques, we present a process where users interactively and iteratively participate in the design, through a series of individual interviews and focus groups. We also present two case studies, for a multimodal and a multi-touch application.

Summary: This article fits in a broader context of a qualitative research seeking for traces or signs of expression, presence and representation of the self from the perspective of teachers as end-user developers of virtual learning environment interfaces. We chose Moodle as the environment to conduct this work and we counted with the voluntary participation of nine teachers with different profiles concerning the area, educational model and target audience. Questionnaire and interview were applied and testimonies were collected, uncovering three ways of self-expression and representation: expression through written language, interface customization and through the content. We focus this paper on the communication practiced via Moodle by means of written language.

Link to Digital Content at Springer

Summary: The increasing dissemination of mobile devices has turned everybody into potential users of mobile applications. Due to the presumed ease of use of these applications along with the uncommon use of their help systems, most do not offer help systems within the applications and those that do are usually accessible only through Internet links. This double presumption that users do not need help because the application is easy to use and users have access to Internet everywhere -- may negatively affect not only the use of the application in some (or various) situations, but even worse may cause users' to misunderstand their goals and possibilities. To explore this topic, we present a user study of 14 users about mobile applications and their (lack of) help systems.

Summary: Social network sites (SNS) are powerful technologies to bring people together and share information, changing the way society interacts in contemporary days. SNS such as Facebook have grown in popularity in recent years, reaching 1,3 billion monthly active users. However, as this network helps to make the world more open and connected, participants inevitably end up losing control over the extent that their personal information may reach among people that belong to their social circle or not. In this context we present +PrivacyCTRL, a model to enhance privacy controls on SNS, which supports the design of privacy settings in order to give users more autonomy over what they publish in these networks. +PrivacyCTRL was applied -- via paper prototype technique -- to three well-known SNS and showed promise in clarifying the privacy settings and improving the user's choice about what to reveal and to whom.

Summary: One of the issues the Brazilian HCI community has paid great attention to is HCI education in the country. One of the efforts has been to understand, through the use of surveys, how HCI has been taught in Brazil. So far, two reports on HCI education profile in Brazil have been presented: one from 2009 that described HCI courses being taught, and another from 2012 that was in response to a SIGCHI demand and targeted a broader audience, not taking into account specificities of the Brazilian context. Therefore, the need for an updated analysis of HCI education in Brazil was identified and a new survey applied. In this paper we present the initial analysis of the results of this survey and delineate what HCI courses have been offered at undergraduate or graduate levels around the country and their topics they cover.

Summary: The low cost and ubiquitousness of digital cameras allow users to collect large amounts of photos. Although storage is not usually a problem, selection of content for presentation requires time and work. Thus, we intend to investigate how users currently deal with the tasks of organizing and presenting their photos. A survey was conducted with 100 participants pointing out their preferences and differences related to age and gender in this subject. The research methodology, the experiment and the statistical results are discussed in this paper.

Keywords: gamification; recommendation; e-commerce

Link to Digital Content at Springer

Summary: In attempt to help users in filtering available products, recommender systems are being used by e-commerce systems to try to predict users' preferences and suggest them new products. Some recommender systems are based in previous ratings and evaluations provided by users to purchased items. When new users or new items join in recommender systems they can suffer by the so called cold-start problem. However, do you rate the products that you bought? This question and other ones were made to 367 participants by an online survey that aims to identify customer profiles and motivations. Also, we investigated user engagement in gamified systems and the effects of tangible and intangible rewards in their behavior. This work presents a theoretical framework that provides basis for defining how gamification can be used to encourage ratings and improve user engagement in tasks that benefit user reputation, item reliability and to overcome cold-start problem.

Summary: The integration between agile methods and UCD has been addressed by several authors in recent years. However, a gap remains regarding how the practices have been described, lacking a standard that both designers and agile practitioners can understand and apply.
This study aims to propose agile usability patterns based on the literature, with a focus on the User-Centered Design early stages. The goal of the proposed patterns is to facilitate the use of the best agile usability practices by identifying more clearly in which context the pattern can be applied, and what is the problem that each pattern solves, presenting examples.

Summary: The highly dynamic nature of domain ontologies has a direct impact on semantic mappings established between concepts from different ontologies. Mappings must therefore be maintained according to ongoing ontology changes. Since many software applications exploit mappings for managing information and knowledge, it is important to define appropriate adaptation strategies to apply to existing mappings in order to keep their validity over time. In this article, we propose a set of mapping adaptation actions and present how they are used to maintain mappings up-to-date based on ontology change operations of different nature. We conduct an experimental evaluation using life sciences ontologies and mappings. We measure the evolution of mappings based on the proposed approach to mapping adaptation. The results confirm that mappings must be individually adapted according to the different types of ontology change.

Summary: Help systems allow users to understand the system they need to use and how to best achieve their goals. In this context, strategic information is fundamental. At the same time this kind of information is very hard to find. We present a case study, with the analysis of the users conversations in a peer help system, in order to discuss how this strategic information is demanded by them. It was possible to verify the importance of this information, how hard it is to describe it, and to discuss some alternatives in this regard.

Summary: The goal of this paper is to compare the performance of two usability inspection methods that aim at anticipating the evaluation process by inspecting Activity Diagrams. In order to achieve this goal, we carried out a feasibility study by following an established inspection process. According to quantitative results, the Usability Guidelines method outperformed the MIT 3 with regards to efficacy and had similar performance regarding efficiency. However, through a qualitative analysis, the MIT 3 was considered easier to remember and to learn and also more useful than the Usability Guidelines. We found out that the Usability Guidelines method could be used for more experienced professionals on usability issues and perhaps has an even better performance. Notwithstanding, the MIT 3 method could be suggested for the use by a little less experienced professionals with regards to usability issues, supporting the formation and training of design and development teams.

[17] Gamification aware: users perception about game elements on non-game context Short papers: emotions and user experience / Ziesemer, Angelina / Müller, Luana / Silveira, Milene Proceedings of the 2013 Brazilian Symposium on Human Factors in Computing Systems 2013-10-08 p.276-279

ACM Digital Library Link

Summary: Many applications such as Foursquase, Stackoverflow and Livemocha are using gamification to try keep users motivated to perform tasks that require the users collaboration and to increase data collection from users feedback. The term gamification refers to the use of game elements on systems and researchers from human-computer interaction (HCI) area have recently started studies to explore its effects on user experiences. In this paper we report the results from a survey performed with 368 participants about the use of gamification, their motivation and perception about it. The results show that users are not aware from some game elements and they have distinct motivation and knowledge about gamification.

Summary: The Teaching HCI Workshop (WEIHC) has had three editions, always held during the Brazilian Symposium on Human Factors in Computing Systems (IHC). This workshop counted with the participation of teachers and researchers in HCI, as well as other stakeholders in the area, and the discussions held during this event has supported the advancement of this area in Brazil. This edition are planned with presentations of articles about teaching experience in teaching HCI, poster presentations showing the use of tools or alternative methods of class work and discussion of syllabus for specific disciplines of HCI courses in undergraduate and graduate students, and topics on HCI for those courses that do not have specific disciplines in their curricula. Moreover, it also intends to discuss suggestions of bibliography to support the disciplines. The goal is, as in the first workgroup about this issue, held in 2006, to have as main result, the suggestion of syllabus, curricula and bibliography for the HCI community.

Summary: HCI Education in Brazil has come a long way. Since 1999, the Brazilian Computer Society (SBC) included HCI in its reference curriculum for its Computing courses. Since then, the community has discussed the perspective of the area in our country. From 2010 to this day, we have held a series of workshops on HCI Education, called WEIHC, as a permanent discussion forum within the Brazilian HCI conference, IHC. We report here the results of the WEIHC discussions and of two surveys, conducted in 2009 and in 2012, to help us assess the status of HCI Education in Brazil. Despite the advances of the Brazilian HCI community, our surveys show that we still face some important challenges. We should curate existing teaching material to further enhance collaboration among professors, to increase the quality of our courses, and to broaden HCI awareness across all related departments.

Summary: The low cost and ubiquitousness of digital cameras allow ever larger collections of photos. Although storage is not usually a problem, selection for presentation requires time and effort. Studies show the existence of user groups that never tried to create digital photo albums or were discouraged by the difficulty of this task. Trying to minimize the effort to create albums, we developed a prototype called Twingle. Using Twingle the creation of an album requires dragging pictures into a page and the program is responsible for positioning and resizing. To investigate whether such an automatic layout generation could be an alternative to users, we made a study exploring Twingle with users from several ages and professional areas. The related works, the performed user study and its results are discussed here.

Summary: User-Centered Design spends a considerable effort on research and analysis before development begins. On the other hand, Agile methods strive to deliver small sets of software features to customers as fast as possible in short iterations. Whereas the two methodologies have tensions regarding requirements gathering and upfront design, they also share similarities. For instance, both approaches are iterative and customer focused. However, there is little guidance on how to integrate these two perspectives and a lack of understanding with respect to the User Experience (UX) Designer's role in an agile environment. Based on four ethnographically-informed studies in two large companies, we aim at providing a better understanding of the integration of Agile development and UX Design by describing the different roles that a UX Designer plays within an Agile environment.

Summary: Social networking websites have been taking a huge space on the Internet. With millions of members spread across the world, these services connect their users through "friendship" relations, and within a short period of time the information is disseminated in the network. Considering Twitter, we investigated how standard techniques of information visualization can improve the analysis of its users' behavior, i.e. the group of people who most closely relate, and the frequency and type of messages they send. This investigation was done through user's studies with a set of visualization techniques implemented in an interactive system prototype.

ACM Digital Library Link

Summary: Social networking sites are powerful virtual technologies to bring people together and exchange information, enabling their users to post messages, videos and photos, make comments, "mark" people in publications and share with others, among other features. Networks like Facebook are growing in popularity in recent years, reaching 901 million monthly active users. However, as this network helps to make the world more open and connected, participants inevitably end up losing control over the extent that their personal information can reach among people who are or not part of their social connection. In this context, we conducted a survey to find out how people have considered the issue of privacy on these networks, and if they are aware or care about the risks that the exposure of information online can bring. This research was focused on Facebook, with the participation of 255 volunteers, and its results and considerations are discussed in this article.
