When I read the VR article, I was thinking that if virtual reality is divided into virtual objects and virtual experiences, the former refers to the objective material basis of virtual reality, while the latter is the perception based on virtual matter. Virtual object is a substitute for the corresponding things in the real world, as far as it is concerned, it is objective and real, and it is material (some kind of electronic image or signal), but in terms of the meaning it wants to express, it is false and unreal.

 

Such as an apple in virtual reality, it has a certain materiality, that is, a group of code, in this sense, we admit that it is objective and real.But it is not a "real" apple, even if the virtual reality technology reaches the point that it not only looks like an apple, but also smells like an apple, and even has all the properties of an apple, but it is still not a "real" apple in the real world, but it is just a set of code made up of 1s and zeros.

 

In this sense, we think it is false and unreal. The virtual experience is the perception of this unique virtual object, not the direct perception of the real things in reality, but because the experience perception generated by the virtual object is close to the real perceptual experience of human beings in the corresponding circumstances. therefore, it is recognized and given certain meaning, such as simulation training and so on.

 

Similarly, this virtual experience has a double meaning. On the one hand, because the virtual object is material, our perception of it also has a material basis-- unlike pure imagination or fantasy, virtual experience has a certain materiality, it is objective and real, and has a certain degree of initiative-- we also recognize the effectiveness of simulation training.

 

Imagine that when a pilot passes the qualification certificate, he says that he has passed the corresponding test in his mind. This will only be regarded as nonsense, but if he passes the test in a simulation module with virtual reality technology, then his experience is recognized by most and given a certain degree of validity. 

 

On the other hand, because the virtual object is not an objective and real thing, the resulting virtual experience is not completely equal to the real experience in the real world.

 

Virtual reality based on logical language is only a copy of past experience. In this sense, it is not as free as the artistic imagination, the latter can completely ignore the shackles of realistic conditions and carry out wild imagination. But if virtual reality wants to be completely divorced from past experience, it either faces failure, that is, the stimulus it gives is inconsistent with the perceptual structure of the experiencer, or the experiencer gives feedback beyond programming that virtual reality cannot handle, thus making the experiencer realize that he is in virtual reality-- which is not dangerous for artistic imagination. Rather, artistic imagination needs this sober sense of distance.

 

However, it is a fatal flaw for virtual reality. Either the experimenter (intentionally) falls into the state of physical and mental separation and changes the cognitive structure with the help of virtual reality, so as to realize the abandonment of the physical body. But its effectiveness remains to be proved. After all, we live in the real world, not as a highly sophisticated machine to receive stimuli from all directions, but "I" and "my body" living in the world. 

 

The relationship between perception and being perceived, as analyzed above, is difficult to achieve in virtual reality.
