It is the change that virtual technology gives birth to a great influence on the human's cognitive activities. First of all, virtual technology has caused obvious change of cognitive relation between subject and object, which includes the change of interaction between subject and object, digitization of cognitive resonance and scene of cognitive model, etc. secondly, virtual technology has improved the subject's cognitive ability and level: the ability of esthesia of the subject has been strengthened, the change of the cognitive structure and the way to obtain information of the subject has been caused and the regulation and control ability of the subject has been improved by virtual technology. Initiative and creativity has been highlighted in the cognitive activity. Lastly, virtual technology has expanded subject's cognitive field, that is to say it has expanded the cognitive space of the subject, and enriched the cognitive source of the subject The appearance of virtual technology leads to great changes of mankind's practices.

正是这种转向使得虚拟技术对于人类的认识活动产生了重大影响：首先，虚拟技术导致了主客体之间的认识关系发生明显的变化，主要包括主客体作用的方式的变化、认识中介的数字化以及认知模型的情景化等；虚拟技术提高了主体认识能力和水平：虚拟技术增强了主体的感知能力，引起了主体认识结构的变化，认识主体获取信息的方式发生了变革，提高了主体对认识活动的调控能力，张扬了主体在认识活动中的能动性与创造性；虚拟技术拓展了主体的认识领域，即它扩展了主体的认识空间、丰富了主体的认识来源。
