Recently, many studies on Mixed Reality have been going on. Virtual Reality can only show virtual objects, but Mixed Reality combines real-world information to open up more possibilities. In the game, interaction between the player and others is an essential factor, and games based on Virtual Reality or Mixed Reality using HMD are no exception. For this, we implemented a Mixed Reality System for the Behavior-like Interaction using an additional device to HMD that supports Virtual Reality. This paper presents the theoretical content, the overall contents of the implemented Mixed Reality System, the experiment, the evaluation, and the results.
