Digital games represent a ludic, attractive and pedagogically interesting possibility for teaching-learning processes. The appearance of several children's games based on creation of algorithmic sequences for controlling characters shows the growing importance given to the development of computational thinking at elementary level. However, the adoption of this kind of game in educational contexts is hindered by the lack of trustworthy design and evaluation methods to access the quality of the games and guide developers and educators. This paper reports the evaluation of a children's digital game for teaching computational thinking, and presents results that contribute to the generation of guidelines related to interface elements, interaction issues and key design choices for performing functions that are common to games of the kind.

Currently, there are many types of computer systems, and it is essential that they have interfaces that allow the user to achieve their objectives satisfactorily. To do so, these interfaces must be evaluated. Researches show promising results when using neurophysiologic measures of users to support the evaluation of traditional methodologies. This work presents the study and development of a software capable of recording and cataloging neurophysiologic measures based on electroencephalogram (EEG). To this end, two EEG low cost, Neurosky Mindwave and Emotiv EEG were used as data acquisition devices. The software was developed using the C Sharp programming language and the manager of database Microsoft SQL Server Express. Through the developed software, called INTELLECTUS, research and studies in the field of Neuroscience can be conducted. Based on related work, an experiment was conducted. In this, it was possible to perform the catalog data for two EEGs.

The advent of Kinect triggered the growth of applications aimed at natural interaction, gesture recognition and interactive environments. Over time, we realized that interface solutions based on such types of interaction grew in a rapid and disorderly way, without any concern for the formalization of development stages. In addition, issues related to the way these interactions are represented, the context in which they occur, and the environmental behavior in response to these interactions became relevant. In this sense, this paper brings a contribution to the practical approach of a Where-What-Why-How Model for the development of interactive environments. The proposal focuses on three main points: (i) actions that must be performed by the interactive environment;(ii) the situations that trigger the implementation of the actions by the environment; and (iii) the expected behavior once the situations have been recognized. The illustration of the proposal is made through a complete case study that contemplates all development stages and the physical implementation of a remote control that triggers actions in the real world (TV) and in the virtual world (graphical representation of the remote control), which compose the interactive environment.

Examples are commonly used as support to teach and learn programming. However, programming students (even the most experienced ones) neglect the study of code and the understanding of the message conveyed by it, preferring to reuse e adapt the code to achieve their goals. This work investigates how students use examples in their activities and, in cases where it is reused, how the appropriation of the code message happens and how it impacts in programmer's self-expression and his/her final message communicated with the program.

Visually impaired people still have difficulties to independent movement in indoor and outdoor environments. In outdoor environments, GPS capability can be used to support orientation. However, the mobility of these users indoors is still a challenge. Advances in technology, emphasizing the contribution of research in Human-Computer Interaction, allow the development of accessible solutions that provide greater independence, security and improvement of life for the visually impaired. In this context, this paper presents the development of a solution to help guiding blind people indoors. This solution makes use of embedded systems low cost, RFID technologies, and mobile devices.

This paper presents a method, invariant rotation and supporting vivacity detection, to perform face detection in catches in real time via the Kinect sensor. The results contribute to areas such as pattern recognition, IHC and computer vision, among others. The possibility of face detection and safely and reliably vivacity can substantially enrich IHC interfaces, increasing the variability of applications that make use of such resources in the design of multimodal interfaces.

The Web 2.0, the second generation of web applications, offers innovative ways for users to access information and to add content, in a collaborative way. Our research is focused on how those systems communicates the reputation, i.e., the validity and accuracy, of the shared information sources. This paper presents a study to characterize reputation communicability in Waze, a community-based traffic and navigation application. We used the Semiotic Inspection Method (SIM), a Semiotic Engineering evaluation method. The results indicate that the reputation communication model is a good opportunity to support decision-making at human-computer interaction time. When the reputation communicability fails, the users should decide for themselves and at their own risk about the information credibility.

We can see progress in the area of Ambient Intelligence (AmIs) with the improvement of embedded systems and technologies using wireless networks. Moreover, the development of studies on interaction between human beings and electronic devices have become increasingly more natural. This new scenario favors the development of ubiquitous computing, in which the relevance of body language is gradually increasing. In this paper, we propose a model of interaction via gestures and test its efficiency through the creation of an infrastructure. In order to assess its usability we developed an experiment with potential users and identified good results. We found that by combining the images identified by Kinect and the interpretation of gestures from OpenCV, improved the gesture recognition greatly.

Ambient Assisted Living (AAL) is an emergent area that provides useful mechanisms that allows tracking elders through sensoring, for example, using mobile devices. It is necessary a permanent attention to these people by caregivers and a growing necessity to create mechanism to support this task. In our proposal, we have a network of caregivers that work together to ensure the wellbeing of elders in their daily activities. This paper aims to model the interaction process of different actors with SafeRoute, an AAL system that pretends monitoring elders in their day-to-day daily living activities in outdoor environments. SafeRoute merges sensor data provided by different sensors built-in mobile devices to provide alert mechanisms for caregivers. We additionally present an upper context ontology to represent general concepts of our context, visualizing the proposed interaction model.
