Abstract: A believable virtual world created by immersion， interaction and imagination techniques in virtual reality technology can bring about not only a visual impact and full of illusion of sensual pleasure for the audience， but also lead to a cognitive confusion of the objective world， subvert all the natural ways of human life and long-term accumulated life experiences， and even cause abnormal or extreme behaviors. The three characteristics of immersion， interaction and imagination in virtual reality technology are respectively analyzed from the philosophical perspective. The dialectical effect of virtual reality technology on audience cognition is explored and the negative effect on the psychology and behavior of the audience is also expounded upon.

Key words: virtual reality, internet, audience cognition
