We previously developed Web3D contents that simulate the procedure for assembling a handmade PC. The original motivation for this project was to enable media-informatics students to deepen their understanding of PC hardware. However, it was found that due to their lack of perspective, conveying information that relates to such virtual manufacturing was quite difficult using conventional 2D displays. In this study, we optimized the graphical contents for a stereoscopic environment that would allow proper perspective to be realized. No significant differences were identified between stereoscopic 3D cases and 2D cases. This result is considered to be due to learner fatigue specific to stereoscopic 3D cases.
