Ontology-driven Generation of 3D Animations for Training and Maintenance

摘要

3D Computer-based animations are nowadays used for training purposes in a wide range of industrial applications like assembly, maintenance and operations. Authoring them is usually a time consuming task, demanded to professional 3D designers, who need at first a good understanding of the involved entities and actions in order to create customized animations. The proposed methodology deals with the use of an ontology in order to filter and understand generic natural language training requests. Once identified the proper actors and actions, they are associated to the corresponding models and movements to be performed in the virtual environment and translated in a 3D graphics format template. The result is a customized animation, which can be created by a non-expert designer and then visualized by the worker on site. The role of the ontology is to reduce the overall complexity of the animation authoring process by assuring the necessary comprehension of the training requests as well as reusability and extensibility of the structure of both modeled objects and of animations驴 components in different fields of knowledge.
