A multimedial tool to study the ear anatomy from virtual models

Abstract

This paper brings up a defined and applied methodology for developing a multimedia web-based and 3D image tool. This to supplement the human ear anatomy learning process by using virtual objects in order to enhance the immersion and interaction in relation to real ones. Traditional learning aids are based on photographs, illustrations, sketches and direct tissue observation through microscopes, but although they supplement each other, some limitations rise due to the microscopic nature of some parts, bones and tissues. In order to overcome physical restrictions, a development of a computational tool offering 3D animated and interactive models of the human ear apparatus along with its related information is proposed according to the specifications given by professionals in the area. The 3D models were developed using medical images, such as computerized tomography, photographs and real models, so realistic virtual objects may be created. The editing process of the anatomic models kept in mind the hardware features of standard computers, so a wide range of users may access and use the tool without losing realism. The validation of this work was done by specialists to guarantee the information and navigation requirements fulfillment of the future testing as an alternative educational tool.
