In this paper, we have presented a novel interaction interface for the 3D environments, which can be an alternative of the high-cost 3D trackers. Even though the mobile devices, which almost all of people are using, can be used as a device replacing the 3D trackers which have been used so far, some appropriate progress verifying the feasibility of this paper‘s interface has not been done yet. Therefore, as a future work, we are planning to conduct a set of experiments as a user study/evaluation to prove its practicality. In the tests, some articles, such as ease of learn/use, intuitiveness, and user tiredness, will be evaluated, and compatibility of the interface will be considered
