Augmented Reality (AR) headsets has become a potential device as an auxiliary tool for practicing physical activities such like Tai-Chi Chuan (TCC). Although some learning systems can display the virtual coach movement in AR headsets, the playing speed cannot be adjusted appropriately just like a real coach stand next to you. In most of the learning system, the common approach is using controller to control the playback system under a specific speed. Once user want to speed up or speed down, he has to do these commands via a controller. In this work, we propose a TCC learning system which will real time detect the delay time between current action of user and virtual coach. After obtaining the delay time, our learning system will adjust speed of virtual coach automatically. With real time speed adjustment, learners can practice TCC with their own pace and virtual coach will slow down or speed up to follow learners’ movement.
