The dissemination of 3D-enabled devices like 3D displays in entertainment environments, smart mobile devices or head mounted systems like Google Glass or Oculus Rift is rapidly growing.
Regarding learning scenarios the use of 3D-enhanced applications is rare.
As the perception of depth in a three-dimensional model is often necessary to understand the principles of operations there is a sufficient potential for the medical sector to evaluate 3d enhanced courses. In our study we evaluated the complexity and effort one needs to create and integrate 3D-models in learning management systems and the learning outcome.
This paper describes our approach to use 3D interactive tooth-models for teaching orthodontists in the context of measures to correct tooth positions. Therefore several chronological 3d models and morphing animations were used to explain the measures and their impact.
To create 3d models different methods where tested. Some methods like laser scanning are very accurate but are unable to produce textures, others are photorealistic, but the 3d mesh is imprecise. Further more there are big differences in scanning time and the ability of scanning shiny surfaces.
In our case especially the use of orthophotographic methods with mobile devices and cloud services to build models was successful.
This case study presents a best practice solution for the creation and implementation of these models in an eLearning course, which was integrated in the LMS moodle to study the potential of this approach.
Some effort of future work is still necessary in order to enhance and transfer this concept to other scenarios and to evaluate the outcome of 3D-enhanced learning courses. | Keywords
