This paper presents the Human-Centered Design process (HCD) applied in the context of educational games using open data about cultural aspects of the city of Recife. The main objective of the work is the collaborative development of an application for smartphones, entitled "Recife Games", which provides an entertaining way to learn about Recife culture. The methodology for the application development was based on the HCD Toolkit and Jakob Nielsen's usability criteria and heuristics. We also used two interaction design techniques, Skeumorfism and Flat Design. The work includes the steps proposed in the human centered design, starting with the specification of a strategic challenge and the following three main phases: Listen, Create and Deploy. Finally, we present statistics related to the application usage on Android platform, that shown relevant user acceptance of "Recife Games".

People with any visual impairment need special support and tools to overcome the day-to-day difficulties in the urban mobility context. The human-computer interaction area (HCI) has studies investigating new technologies to provide more accessibility and usefulness to this group of end users. In this context, this paper presents the results of research that applied the design thinking method to understand the users' requirements in a group of visual impaired people that study in special institute that supports their teaching. For example, a common complain obtained from our field research was the wrong information obtained from pedestrian and service operators when they needed to know the bus routes. We have monitored visual impairment users in practical evaluations of usability and accessibility using the Rota Urbana Voicer tool, that provides an extension to an existing tool to search public transportation routes using voice commands in a smartphone. We have also identified different suggestions to improve our tool based on other studies in the literature.
有视力障碍的人需要特殊的支持和工具来克服城市交通环境中的日常困难。人机交互领域(HCI)研究了新技术，为这组最终用户提供更多的可访问性和有用性。在此背景下，本文以一群视障人士为研究对象，运用设计思维的方法来了解视障人士在特殊学院的教学需求。例如，我们在实地调研中得到的一个常见的抱怨是，当行人和服务运营商需要了解公交路线时，他们获得的信息是错误的。我们使用Rota Urbana Voicer工具对视障用户的可用性和可访问性进行了实际评估，该工具为现有工具提供了扩展，可以使用智能手机中的语音命令搜索公共交通路线。我们还根据文献中的其他研究确定了改进我们工具的不同建议。

Provide accessible interfaces for the deaf community is one of the major challenges of research that is presented in the IHC area. In this scope exist different approaches to automated text translation of the Portuguese language to sign language. This paper presents a strategy based on the use of expert systems to support the generation of an interlanguage to aid the Portuguese language translation process to the language of signs, contemplating syntactic and semantic aspects. The participation of experts (interpreters) occur in all development stages of the G'Libras system and is essential to produce technologies that meet the needs of the deaf community.

The growth of the elderly population and the social network's benefits to this public makes essential a good communicability of these systems for the elderly users. This article describes a qualitative research using the Communicability Evaluation Method for Collaborative Systems with two user's profiles on Facebook. The objective was to evaluate if the limitations from the aging process can generate different results in the contrasted profiles. As a result, we observed some aspects to be reviewed on Facebook interface as: improving meaning system, defining more clearly organization criteria for information and correcting usability and accessibility issues that contribute to communicability breakdowns during the elderly's interaction.

The Climate Challenge is an online competition in the tradition of games with a purpose that combines practical steps to reduce carbon footprint with predictive tasks to estimate future climate-related conditions. The application is designed to increase environmental literacy and motivate users to adopt more sustainable lifestyles. Its feedback channels include a leaderboard and a visual tool to compare answers of individual players with (i) the average assessments of their direct social network contacts as well as the entire pool of participants, (ii) a selected group of experts, and (iii) real-world observations.

Gamification has become a popular strategy to increase the engagement and participation of users in social systems. Despite the popularity that now reigns, we identified that gamification can not be treated simply as award points and provide badgets for users. Care must be taken, since the choice of the game mechanics must consider the profile of the user as a player. If such considerations are not made properly, the desired goals by the developer cannot be obtained. In other words, one needs to understand the relationship between the developer's goals, the game mechanics and the profile of users (players). The lack of computational tools to support the developer to consider how these three aspects relate to and impact, led us to propose GameWork. It is a Service-oriented Architecture to support gamification in general, especially to help monitoring the system and the players behaviors with respect to the incentives provided. This article describes GameWork and an example of its implementation in a commercial social network.

To perform emergency coordination, people in a command centre need to process a large amount of data about the incident to make decisions, generally, under time pressure. A main challenge is to quickly obtain contextual information about the situation, which can be obtained from people in the place of the incident, in a crowdsourcing manner. This paper presents our investigation about visualization mechanisms to support command centres on analysing crowdsourcing information regarding emergency situations. As contributions, we highlight: 1) discussion of existing visualization mechanisms and their support on emergency management; 2) prototype of the Emergency Response Toolkit (ERTK), a set of tools to support command centres on using information from the crowd, e.g. in large-scale events; and 3) evaluation of ERTK and its visualization mechanisms with 11 emergency experts, in Brazil, Austria and Spain, collecting feedback to improve information visualization for emergency management.

Video games are constantly evolving and new ideas for user interactions are being proposed. Within this context, innovative technological artifacts are being created in order to enable interaction flexibility, involvement in the game and rewarding experiences for the players. In recent years, the medical field has benefited from video games with new treatments in the area of physical and occupational therapy. This paper presents a low-cost technological infrastructure, capable of creating games for the area of body movement rehabilitation, utilizing an innovative wearable control that interacts with this new video game. In order to validate this proposal, we conducted initial experiments with potential users, pediatric neurologists and physical therapists. The user experience was a success and the results indicate promising usability in the medical area.

In formal learning environments there is a diversity of interests and abilities that need to have space in the interaction between those involved in the production and sharing of knowledge. This diversity of skills is still not supported by existing systems, when the goal is collaboration on active learning models. The design solutions need to align systems with the needs of students and teachers and the learning objectives. This article proposes an analysis based on artifacts of Organizational Semiotics, which allows us to understand learning requirements that influence the design of collaborative systems. This analysis informed the development of a technological platform to support an active learning environment. Experimental results on the use of the system in teaching of HCI indicate good user acceptance and pointed out its viability in mediating the engagement and collaboration of those involved in active learning.
