Resumo


Virtual reality simulators for medical training allow the student to learn and train medical procedures safely, before performing on a real patient. By collecting data from the trainees while they perform in the simulator, it is possible for the system to automatically give feedback about the student’s performance in the procedure, in real time, making the training more independent, while also yielding information to the instructor that can be insightful regarding their student’s learning. As studies using machine learning techniques to automatically assess performance in virtual reality simulators are scarce in the literature, this work proposes a model by comparing the results of different classifiers by using data collected in a dental simulator. The results so far have shown that the Naive Bayes classifier has achieved a lower Accuracy in most cases when compared to the Support Vector Machine, Multi-layer Perceptron and Random Forest classifiers.
