Virtual reality technology is gradually emerging in any society. Due to declining birth rate and increasing elderlies, many traditional flavors and cooking skills are gradually disappearing. Therefore, in this thesis, we use deep learning and current mixed reality technologies to solve the above problems. This thesis focuses on the training of chefs so that users can use MR devices to assist the training of independent cooking oyster fried without the guidance of a chef. The experimental results show that MR devices with chef training functions can effectively train chefs for cooking the oyster fried.
