Recently, many learning systems, such as e-learning and WBT (Web Based Teaching) systems have been developed. In these systems, users can get educational contents and graphical material in a remote place through the network. However, the learning is always one-sided. That is, all users learn the same contents and cannot convey their states like "What is he or she doing now?" to these systems. Therefore, these systems are not necessarily satisfying all the users' demands. In this paper, we propose an interactive learning application of cooking in mixed reality (MR) environment. In an MR environment, a system should not only provide the useful knowledge, but also recognize users' state. Furthermore, by making a parallel transition model about cooking, it is possible to control the user's cooking process. Therefore, users can learn details about cooking more flexibly and effectively.
