The level of variability in psychomotor behavior and the use of several distinct sets of equipments in Reaction Time (RT) assessments might jeopardize the validity and reliability of such measures. This study presents the development and verification of Emboici Robot-a robot capable of performing accurate RT assessments consisting of response to a visual stimulus by pressing a button-whose purpose is to measure the accuracy of RT assessments. We evaluated the accuracy and precision on four different days, each providing 300 measurements. These assessments generated a RT of 46.95ms (+6.04). No significant effects were found in the RTs obtained and, as a result, there is evidence that the Emboici Robotis stable, reliable, and precise. The robot can be a viable solution for verifying precision and accuracy of any given software with simple RT assessments with visual stimulus requiring as response the pressing of a button or key.
O objetivo deste estudo foi descrever o relato de uma experiência utilizando recursos de videoconferência com software livre para fins de defesa de mestrado em um programa de pós-graduação. A solução apresentada inclui um tablet, celular com câmera e sistema Android e os softwares freeware: Skype, DroidCam, PowerPoint OpenOffice Remote e LibreOffice Impress, além de outros recursos necessários à apresentação propriamente dita (projetor multimídia, computador, som, microfone, além de outros). O uso do software livre para a videoconferência mostrou-se uma ótima maneira de apoiar a formação de bancas de defesa à distância permitindo a integração no processo de formação de estudantes.
