Abstract
Maintenance operations play a critical role in both civilian and military domains, and they can influence the state of their operational readiness. Thus, having access to superior solutions that can be used to train maintenance personnel is essential. Virtual reality (VR) technology, with its capability to simulate 3D objects with high fidelity, is a good candidate for maintenance training solutions. The main component of a large majority of maintenance tasks includes assembly and disassembly of physical setups. These tasks involve judgment of distance, depth, sizing and fit. Various factors may influence the operator’s performance in a VR system by affecting perception of the components and, consequently, task execution. Two such factors are stereoscopic depth cue and immersion. This study uses assembly tasks as a context for exploring operator performance while manipulating virtual objects positioned within arm’s reach. A user study collected a comprehensive data set over four distinct experimental conditions: immersive stereoscopic, immersive non-stereoscopic, non-immersive stereoscopic, and non-immersive non-stereoscopic. Data analysis suggests that the immersive stereoscopic condition was superior when compared to others; most people in that condition finished their assembly tasks, and they did it in shortest time. No significant simulator sickness issues were recorded in any condition.
