The next challenge is intuitive operational issues. By the way, is the operation system like the movie of the minority report intuitive? What kind of response is intuitive operation in the first place? The operation by the existing VR device is essentially affected by the inconsistency of the operation system in the real space and the VR space. It is technically impossible to completely match the operation system of real and virtual space. It is important how to get closer to virtual and intuitive operation with existing VR devices. While solving these issues, we will move on to the next title change. The next title change is a mismatch between the virtual sense and the real sense that are reproduced. There is an idea that even if the cost is high, it is better to match the reality perfectly, but a method to reproduce the whole sense of human beings has not been realized yet. Therefore, it becomes a debate about how much should be reproduced for each event. It is possible to reproduce the senses with various reproduction devices. The feeling reproduced on the rim is as shown in the figure. Various sensations can be reproduced with a dedicated inexpensive device. The final challenge is post-traumatic stress due to excessive reproducibility, which can result from recreating negative emotions. In order to keep a person’s mind safe, mental disorders must be completely prevented.
