Abstract
AbstractIn product life cycle management, the effective maintenance system is important to enhance the product’s life. In recent years, the Information and Communication Technologies are rising, many computer aided product service systems are developed, i.e. e-Maintenance. Among these technologies, the Augmented Reality is becoming more and more popular, and many applications are proposed. The user-friendly and intuitive display design provides users a new experience in performing maintenance. This study proposed an augmented reality maintenance training and maintenance system, which used iPhone4 as the maintenance object. To verify the performance of augmented reality system, this study compared printed manual and computer-assisted instruction. Each subject was requested to complete three levels of task difficulty and training methods. The response measures included the completion time, error rate, subjective mental workload and system usability scores. The results showed that the female subjects give a higher score on system usability. But there was no significant difference in task completion time, error rate and subjective mental workload. In task difficulty, the simple task had the least completion time, error rate, workload, and the highest system usability score. On the other hand, the difficult task had the highest completion time, error rate, workload, and the least system usability score. In training methods, the manual approach had the worst performance. It had the highest completion time, error rate, workload, and the least system usability score. The augmented reality system had the least completion time, error rate, workload, and the highest system usability score. In addition, the augmented reality system was faster than the other training methods to complete the task in different difficulty levels. The result showed that using the augmented reality in training had better performance and user satisfaction.
