Empathy is a sense of understanding another person's feelings and is an important element within all relationships. Currently there have been no solutions(More)
— The pervasiveness of computer devices in everyday situations poses a fundamental question about Computer Sciences as being part of those known as basic sciences. However, it would be more beneficial not to consider computation only as a technique, but instead as a way of reasoning and problem solving. Under this perspective, there are inherent(More)
Including Human-Computer Interaction (HCI) topics in courses of different levels may help students appreciate the importance of this field. Many didactic experiments have been previously described. These experiments are often related to the undergraduate or graduate levels, but some HCI topics should also be taught in middle-level professional education(More)
Human-Computer Interaction topics have been previously used to motivate and attract students to the field of Computer Science. However, as students are growing up in contact with several interactive computational devices, one could suspect that they already possess an empirical, informal knowledge about the quality of some types of human-computer(More)
RESUMO Este artigo apresenta o desenvolvimento de um curso prático de Interação Humano-Computador, integrado ao estudo de Engenharia de Requisitos, em uma universidade chilena. A disciplina tem como objetivo explorar as relações interdisciplinares entre as duas áreas, mostrando como elas podem ser complementares. Propõe-se a identificação dos estilos de(More)
— Virtual Worlds (VWs) are computer simulated environments, in two-or three-dimensions (3D), where hundreds of people can interact with each other in real time. Current heuristic evaluation can potentially identify issues related to the usability of VWs, but it may miss domain specific problems. For this reason, the development and use of appropriate(More)
This paper introduces the Gaze based Interface Extensions (GInX) architecture designed for the development of eye-gaze enhanced attentive interfaces. The architecture is composed of 3 modules, the domain, user, and attentive modules. In the absence of information about the user and the domain, the attentive module controls the cursor using gaze and target(More)
