Accessibility actions in Distance Education (DE) seek to contribute to the integration of deaf students in higher education. For the actions that can be proposed, it is necessary to be well acquainted of the needs of this target audience in terms of communication, language and interface design. The aim of this study was then to evaluate the communicability of the Virtual UFMG interface, customized in Virtual Learning Environment (VLE) Moodle, using the Semiotic Inspection Intermediated Method (SUM). The application of this method revealed the main communication problems in the Virtual UFMG interface, apprehended the special needs of the deaf in both situations, in the DE context and the VLE Moodle environments. The results from this application also showed the relevant categories of the system's use and also proposed suggestions for the interface improvement. It was then possible to generate indicators on accessibility in distance education written in Portuguese and focused on deaf users, contributing to their accessibility to DE contexts of academic studies.

As the IHC conference series matures, the Brazilian HCI research community may benefit from an introspective account of its development. We have analyzed the metadata of all full papers published in IHC, the CV of the most prolific authors (i.e. the 105 authors who had more than one paper at IHC), and elaborated a survey to collect data regarding researchers' migration. In this paper, we analyze how researchers have migrated from their institutions of origin to obtain their advanced degrees elsewhere, and how many have come back and some have moved to yet another institution following work opportunities. This migration has shaped collaboration and fostered emerging HCI research groups in diverse institutions, contributing to the diffusion of HCI research throughout Brazil. This paper provides a big picture of the community and a historic perspective on how we got here.

The major challenge for usability tests on mobile systems is to reproduce the context in which they are used. This paper points out some of the main difficulties encountered in the evaluation of such mobile systems, considering the real context of the user. Considering the need to assess such applications on the user's context, it was conducted a field study to evaluate an urban mobility system and, for this purpose, it was proposed a collection instrument, which can be used by the observer to take notes related to the evaluation, enabling various forms of content (observations, important points of the environment, user's verbal utterances, etc.). Through the field study, it was evaluated the benefits of using the proposed instrument, as well as identifying some of the difficulties faced in this type of study, i.e., evaluation of mobile systems on the move.

There are still many communication barriers for the deaf, especially among the non-oralized natives and the listening public. Technology advancements can contribute to minimize this problem with development of vocalizer synthesizers. This paper presents the software development method of "ILalk4U", which converts words and phrases from LIBRAS into spoken Portuguese, providing to deaf more autonomy without the need of human LIBRAS translators at bank branches. Lhe application was developed for Android smartphones using text-to-speech and touch screen technology. Was validated by three LIBRAS translators and smartphone programmers who evaluated it positively.

The pre-linguistic deaf bilingual often have difficulties in understanding of textual information available on the Internet because of their linguistic specificities. This public is entitled to access health information guaranteed by law. However, most health campaigns available on the web are not suited for pre-linguistic deaf bilingual. Thus, this work focuses on investigating and identifying the barriers faced by these users that hinder the understanding of the content of a health campaign on the web. In this context, from the observations of these users on textual information, images and videos were generated recommendations that may contribute to the understanding of the campaign by the public.

Color is one of the most important dimensions of visual understanding and it has the power to evoke emotions. In this sense, choosing the appropriate color for user interface design may cause specific emotions, improving human-computer interaction. However, current studies do not support the designer in the choice of appropriate colors when it comes to a spectrum of emotions. Thus, this article proposes Bianchi's Color Wheel, which combines colors to Scherer's Semantic Space of Emotion. This association is the result of a systematic review conducted in seven databases. The proposed wheel allows designers to choose colors, including variations in saturation and brightness, taking into account the emotions mapped in Semantic Space.

This paper describes the development of a conceptual control model for Assistive Technologies applied in Environment Control, with electroencephalographic analysis as a means of communication. The control model aims to facilitate the interaction between the individual and the environment, enhancing aspects of existing communication, as well as add quality in the execution of certain tasks of day-to-day. Experimental results demonstrate the feasibility of the communication process developed based on the proposed model, observed by success in 78.33% of communication tests.

The use of mobile devices such as smartphones and tablets by different group of people has been growing in Brazil. Among the various audiences the elderly persons may be highlighted as a group who has different needs with regard to interaction with mobile devices. In parallel, the Facebook has been intensely adopted by elderly too. Considering the above aspects - the use of mobile devices and the inclusion of elderly users in social networks - the objective of this paper is to present the results of an exploratory study on the interaction of elderly users in the Facebook on mobile devices in Brazil, defining the personas that represent these users. For this, two methods were performed: a survey with 271 potential users that provided the data to delineate 3 personas, and a participatory design to verify if the real users, who represent the personas, had different characteristics when compared to the proposed personas.

Usability evaluation is a group of systematic activities that should be performed by software developers in order to identify usability problems. A widely used strategy to evaluate usability is known as User Observation and aims to analyze whether the interaction capability provided by the software is appropriated or not. Techniques, such as, Verbalization is widely used to support the evaluations based on observations due to the reason that it provides data about the quality of user interaction. In order to automate the usability evaluation test and to minimize the evaluation time, we developed a tool named ErgoSV, which is based on the verbalization technique and is capable of automatically recognize words defined in a keyword list. ErgoSV also collects, analyzes and provides relevant information about the usability test, such as: a list of pronounced words, pronounced words counter, interfaces (set of screens / video) spoken at the moment of the pronunciation and the exact time moment of pronunciation. Some usability evaluations were conducted with applications from diverse domains and showed the effectiveness of utilizing keywords to perform usability evaluation based on verbalization technique.

Mobile devices and applications for communication, such as WhatsApp, Facebook and Twitter, are already present in educational contexts. However, their use is generally restricted to the original purpose of informal communication without taking advantage of their potential to promote interaction in formal settings. In this paper, we investigate the design and use of mobile applications in formal communication processes, exploring meaning evolution of WhatsApp use in a real context. We propose a system to enable students to conduct preparatory pre-class activities using WhatsApp with text commands and multimedia messages. Our analysis of the system use suggests that it is feasible to appropriate mobile communication applications with which students are already familiar for the use in formal contexts.
