A study on the quantitative design and documentation for the VR based training contents realism

Abstract

The serious game which is utilized for educational training has been operated using I/O (Input/Output) devices like keyboard, mouse and monitor. Recently, serious game is advancing towards VR (Virtual Reality) based training system by providing interaction functions between virtual visualization environment and real action of trainee by wearable devices, such as motion recognition system and HMD (Head Mounted Display). For acceptance test of VR based training system, hardware testing is possible by using test metrics which can be described on its specification. But VR based training contents as a software including virtual visualization environment has many difficulties for testing due to lack of quantitative test metrics about realism which means similarity between real environment and its virtualized environment. In this study, it is suggested quantitative design and documentation methodology of VR based training contents using test models derived from ISO/IEC 25010:2001 SQuaRE (System and software Quality Requirements and Evaluation). The suggested quantitative design document has been experimented through the development of a VR based plant safety training system and has verified its usefulness as training contents test metrics for testing realism which is an emotional factor.
