The effectiveness of virtual reality for overhead hoist transport vehicle wheel replacement training: a focus on visual and haptic feedback

Virtual reality (VR) has gained popularity in the past decade as a training tool, with haptic feedback now integrated into VR consumer devices. Understanding how different modalities work together to improve user experience is crucial. A large-scale semiconductor company processes 300 mm wafers with overhead hoist transport (OHT) vehicles, which play a significant role in productivity. However, the company loses experienced employees and leaves unskilled ones, requiring proper training. Unplanned downtime on OHT vehicles for preventive maintenance (PM) training can significantly impact production output. This research aims to evaluate the effectiveness of VR hand controller feedback for OHT wheel replacement. Participants were divided into groups using VR (Visual Feedback) and VR (Haptic Feedback) to perform maintenance tasks. The experiment showed a reduction of 7.88 % and 6.41 % in task completion time (TCT) and 39.36 % and 39.02 % in error counts using VR (Visual) and VR (Haptic) based instructions. The survey analysis revealed that most participants preferred VR and visual feedback methods for performing maintenance tasks in VR applications. Keywords: Haptic, visual, virtual reality, overhead hoist transport (OHT)
