During Human Computer Interaction design, the MoLIC (Modeling Language for the Conversation Interaction) interaction diagrams can be used as a basis for building other artifacts, such as mockups. However, if the MoLIC diagrams have consistency or completeness defects, such defects can be propagated to the artifacts that are built based on these MoLIC diagrams. For this reason, we should carry out an inspection in MoLIC diagrams, to prevent the propagation of defects. This paper presents a feasibility study conducted with the MoLVERIC Cards technique, a technique that helps the inspection of MoLIC diagrams. The results show the participants' perception regarding MoLVERIC Cards technique and discuss opportunities for improvement.

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.

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.

This paper introduces a study to analyse the users impressions about different visualization techniques. To achieve this, we used the Spot tool, which provides a set of different visualization techniques to users with information retrieved from Twitter. This study was conducted with a sample of 7 Twitter users who have never used this tool before. We collected their impressions and interactions with the system on each visualization technique available. When running a qualitative analysis of the data gathered, an interesting set of results were found. Advantages and disadvantages for each visualization technique introduced were found by all users. This led us to a discussion on where each kind of those techniques would be better introduced or used.

The Web information technology promotes many facilities to people. It allows them to gain more time in performing transactions, payments, purchases and access to information. However, this type of technology has still been far from the deaf community reality, because of the lack of accessibility provided by these computer systems. In this context, this paper investigates the needs of the deaf community for access to Web sites with support for evaluation mechanisms. Initially, the accessibility guidelines for the deaf were identified using the view of several authors. Afterwards, the accessibility evaluation mechanisms were used to analyze some Web Site News. Thus, it was possible to highlight the positive and negative accessibility issues found in Web Sites.

This research investigated the use of the Semiotic Inspection Method (SIM) in digital games, by employing it in the analysis of the following games: Ingress, Kinectimals and Just Dance Now. In the research, we analyzed to what extent SIM can be used to assess the communicability of digital game interfaces, considering the semiotic idiosyncrasies of that software domain. In this paper, we present the results from the use of SIM in those games, thus pointing out some limitations of the method for the digital game domain, in terms of communicability features that could not be assessed.

Computer Supported Collaborative Work (CSCW) denotes a class of systems with which users interact to cooperate, coordinate and communicate with one another. New challenges led various research fields to study CSCW, especially interaction design. In order to support the interaction design of collaboration based on Semiotic Engineering at a tactical level, an extension to the MoLIC (Modelling Language for Interaction as Conversation) language was proposed, allowing designers to consider the influences between users, cooperative tasks and awareness mechanisms. The extended language is called MoLICC. In this work, we present an analysis of MoLICC using the Cognitive Dimensions of Notations (CDN) framework, which allowed us to find limitations in the language. Results point to possible improvements to the language and features for a tool to support interaction design using MoLICC.
计算机支持的协同工作(Computer Supported Collaborative Work, CSCW)是一类系统，用户与之交互以相互合作、协调和通信。新的挑战促使各个研究领域开始研究CSCW，尤其是交互设计。为了在战术层面上支持基于符号学工程的协作交互设计，提出了MoLIC (modeling Language for interaction as Conversation)语言的扩展，允许设计师考虑用户、合作任务和感知机制之间的影响。这种扩展语言被称为MoLICC。在这项工作中，我们使用符号的认知维度(CDN)框架对MoLICC进行了分析，该框架使我们能够找到语言中的局限性。结果指出了可能对语言和功能进行改进的工具，以支持使用MoLICC进行交互设计。

We report on our design of Acropolis, a social computing platform that allows citizens to build and share their own narratives about long-running news stories of political nature. A key goal of this research project is to explore the following design opportunity: how can we re-design news stories in order to engage citizens in their reading and curation? We have hypothesized that one way of achieving this goal would be by effectively supporting user-curated narratives, yet allowing users to socially engage in different perspectives and plots in a story. Using a research through design methodology, we conclude the first cycle of this study with a set of design recommendations for building similar platforms.

Identifying maximum/minimum values in different charts is a common goal when users are interacting with visualizations. Moreover, this can be a challenging task when the user is interacting with space-filling visualizations. Space-filling methods consider a 2D area to represent values, however, low values that might be interesting for decision makers are commonly obfuscated by such approach. In this context, we conducted an eye tracking study with 12 target users to analyze how scale inversion (area proportional to 1/value) can support the identification of elements with small values represented in treemaps. Results show that when the inverted scale supports the task, users are able to identify elements individually and in a less ambiguous way, but took more time to interpret the inverted scale treemap. With the presented results, we expect that Human-Computer Interaction practitioners working on space-filling visualizations to include interactive scales to invert the visualizations scale when the task at hand involves evaluating minimum and/or maximum values.

Multimodal serious video games are relevant tools to enhance the cognitive skills of people who are blind. For this purpose, it is necessary that designers and developers be able to create interfaces and interactions using the multimodal elements properly. Thus, there is a need to know the relevant elements for such applications, as well as to understand their roles and relationships. In this paper, we propose and discuss a 4-dimension classification: Interface, Interaction, Cognition, and Evaluation. Such classification was assembled from the features related to the design and evaluation of 21 multimodal video games and environments, identified via a bibliographic review based on the systematic review approach. Besides, we classify and discuss the 21 multimodal applications into the proposed classification.
