Collaborative Virtual Environments (CVEs) can be seen as resulting from the convergence of research on Virtual Reality and Computer-Supported Cooperative Work. In this sense, the development of a CVE involves activities related to the implementation of a distributed system as well as the construction of virtual worlds that will be accessed by the users.(More)
This article presents the CVE-VM, a Collaborative Virtual Environment that has been developed for educational purposes. The system supports collaborative learning, according to the constructionism approach, and is intended to be used in Brazilian schools by children and teenagers students. The article focuses mainly on design and implementation aspects,(More)
Software Requirements Specification is one of the first phases of system development. This phase results in the Software Requirements Specification (SRS) document, which must contain a complete, concise, high-quality description of the system being considered. The quality assurance of SRSs depends strongly on the use of appropriate techniques. This paper(More)
The increasing dissemination of information demands new techniques to represent and visualize data, so that the user can understand information sets to support decision-making in a fast and adequate way. This paper presents the DATAVIS-AR, a Virtual Environment for Data Visualization that incorporates Augmented Reality, which allows graphics to be(More)
—Games have fascinated people in activities related to entertainment, education, health care, etc. The use of augmented reality technology, using computational support, brings the game from the computer to the user space, making the interaction friendlier. This paper introduces augmented reality and makes considerations on the ARToolKit software, pointing(More)
This paper focuses on the Goal-Question-Metric (GQM) approach, which has been proposed as a goal-oriented approach for the measurement of products and processes in software engineering. First, the GQM is characterized, and then, the <i>GQM-PLAN</i> tool, is described. The <i>GQM-PLAN</i> was developed to support the preparation of measuring plans based on(More)
