Interactive 3D learning contents based on 3D meme media architecture

摘要

In-house training and customer training of step-by-step assembly processes are one of the most potential applications of e-learning to manufacturing industries. Use of the 3D modeling of target products as interactive visual composite objects with some constraints defined among their components enables trainees to directly manipulate their components, and to assemble/disassemble them as if they physically exist there. In this research, we show such a 3D modeling system based on the 3D meme media architecture IntelligentBox, and its application to in-house and customer training of assembly processes.This paper shows that 3D contents have more potentiality in skill-acquisition training than 2D contents, especially for teaching mechanism and assembling/disassembling procedures. It also shows that 3D meme media architectures reduce lead time for developing 3D contents with many functions and motions. The lead time becomes about 1/5, compared to conventional tools.This paper also proposes a 3D pop-up book that embeds an individual learning content in each page, showing its 2D image. When such an image is mouse-clicked, the corresponding 3D learning content will pop up from this image. Such a 3D pop-up book can manage lots of related learning contents, and define hyperlinks among them to differently guide trainees of different levels and/or different characteristics.
