    A crescente utilização de Ambientes Virtuais Tridimensionais (AVs 3D) em contextos educativos evidencia a importância de delinear pesquisas em relação à avaliação da aprendizagem e de Habilidades Sensório-Motoras (HSM), como forma de verificar se tais ambientes colaboram com o processo de ensino e treinamento virtual. Assim, este trabalho apresenta métodos de avaliação da aprendizagem e HSM em AVs 3D, em contextos educacionais, pautados em Nunes (2014) e Anjos (2014), validados a partir de estudos experimentais e análises estatísticas. Os resultados revelaram que é possível medir o nível de aquisição de conhecimento e de HSM a partir dos modelos propostos. Palavras-chave: Ambientes Virtuais Tridimensionais. Avaliação da Aprendizagem. Avaliação de Habilidades Sensório-Motoras

    Currently, the micro-robotic cell injection procedure is performed manually by expert human bio-operators. In order to be proficient at the task, lengthy and expensive dedicated training is required. As such, effective specialized training systems for this procedure can prove highly beneficial. This paper presents a comprehensive review of haptic technology relevant to cell injection training and discusses the feasibility of developing such training systems, providing researchers with an inclusive resource enabling the application of the presented approaches, or extension and advancement of the work. A brief explanation of cell injection and the challenges associated with the procedure are first presented. Important skills, such as accuracy, trajectory, speed and applied force, which need to be mastered by the bio-operator in order to achieve successful injection, are then discussed. Then an overview of various types of haptic feedback, devices and approaches is presented. This is followed by discussion on the approaches to cell modeling. Discussion of the application of haptics to skills training across various fields and haptically-enabled virtual training systems evaluation are then presented. Finally, given the findings of the review, this paper concludes that a haptically-enabled virtual cell injection training system is feasible and recommendations are made to developers of such systems

    MUSTe method for quantifying virtual environment training system efficacy

    Full text link
    In the current era increased attention and interest of utilizing advanced computer technologies for training and education at all managerial levels and functional areas is apparent. One of such technologies, virtual environment (VE), is perceived to be effective in enhancing human abilities to learn abstract concept and complex procedural tasks. Despite its adaptation for training and fast-paced technological advancements, ways in which to evaluate efficacy of such technology are unclear. We have approached this problem by developed a new evaluation method focus on cognitive, affective and skillbased learning dimensions, based on traditional usability evaluation methods but tailored to specifically suit for the quantification of 3D VE system. We first describe the construct of the new method and then report a study utilizing the method in the context of quantifying a VE efficacy in an object assembly task. At last, we discuss the implications of such a method.<br /
