Recently,Virtual Reality (VR) technology has developed quickly,together with research conducted on various elemental and related technologies and research in various fields of its application.We experimented about the delay.The haptic media is very sensitive to the network delay and its jitter and packet loss.The AHP is one of methods to evaluate physical phenomena as correctness of the human sensation. In consequence of its application to the present experiment, it was made clear that the haptic media could be estimated from the delay times. An experiment was conducted using the AHP technique into the effect of feedback force delay on users by using the normal feedback force of a spring as an experimental model. The experiments in this study showed that there is a time delay threshold of 4 ms or more. In addition, when a thorough experiment was conducted in this range, it was found that humans could perceive a variation (difference threshold) in the delay of feedback force for a virtual spring that is between 4 ms and 5 ms.
