The latency is a fundamental and important value in the specification of HMD. However, the HMDs of the state of the art equipped with the latency compensation, the notion of the simple lag is not enough to describe the dynamical characteristic of them. The purpose of this study is to evaluate the average latency as the equivalent simple lag and the accuracy of compensation by the experiment. Further, the dynamical distortion caused by the lag compensation is also evaluated.Oculus Rift DK2 is chosen as the target HMD of this evaluation. The average latency was approximately 26 ms without lag compensation, and it was about 1 ms with both of the Prediction and the Timewarp.
