Virtual Reality-Based System for Training in Dental Anesthesia

摘要

This paper presents the development and preliminary evaluation of a Virtual Reality-based system for training in dental anesthesia. The development focused the simulation of an anesthesia procedure task. The evaluation involved graphic and haptic issues and had the presence of experts in the dentistry area. The assessment aimed at attributes that may influence the human-computer interaction, hindering realism, an important challenge in systems of this type. The attributes selected were: the update rate, the appearance of the virtual models and the number of viewpoints of the virtual environment, as well as the characteristics of the haptic device. Despite constraints were found, in the perception of the experts, the system may provide realism and help with the training of certain tasks.
