From https://note.com/yunolv3/n/n684f3bcb4e52, there is a discussion about the concept of a “Virtual Reality Reading Book.” The document mentions the essay titled “Baji Seminar Essay 1S Semester” as a reference.
The concept of dividing things in this way seems to be the basis for thinking about various things. This is referred to as the “perspective on things.” It is a useful perspective when considering computers as interfaces, not just limited to VR.
In addition to this, there is another perspective presented. From https://note.com/yunolv3/n/n684f3bcb4e52, there is an image shown that depicts the “real world” as the outside. Some people find it strange to consider the “real world” as something separate. They suggest that it should be placed parallel to the “simulation system.”
