We showed that it is feasible for constructing the Artificial Reality (AR) system on a personal computer in the former report. It was also found that easy movement of sight line and more accurate vehicle modeling are important for applying Container Freight Station (CFS) management. In this study, Head Mounted Display (HMD) is introduced to the AR system in order to facilitate the movement of sight line. A series of tests for a prototype forklift (3.5ton type) and for a virtual forkift in AR system is carried out, in order to compare the characteristics of the CRT display system and that of the HMD system. The time for performing the jobs and flicker-value are measured, and the direct question of inquiry for system drivers is carried out. Results are summarized as follows; 1. HMD system has better performance than CRT display system in workability. The measured time for a virtual forklift in HMD system is almost the same as the time for a real forklift. 2. Binocular stereoscopic display is more effective than monocular stereoscopic display. 3. Although the time performance is poor, the CRT display system is highly rated in the direct question of inquiry. From this result the CRT display system can be used for the jobs with less sight line movement.
