From the view points of informatics, the process of cognition is a series of receiving managing ,outputting and back-feeding activies in deed. Such dynamic process is called "cognitive pattern" presupported by the intellect as living intent, do cognitive pattern has evoluted into "Human-computer" model.Secondly, informationization has made social activies more efficient. The consciousness of making full use of information has become on unintegrated part of the whole social ideology. It absolutely exerts active impacts on social activies. Especially the virtual technology comes into being and becomes mature.

按照信息论的观点，人的认识机制实质上是获取、加工处理、输出并反馈等一系列信息的运动过程，形成所谓信息的反映论模式；计算机网络日益智能化的前提下，认识模式逐渐演变成"人—机"为认识主体的新认识模式；其次，信息化社会随着信息实践活动的日益增强，信息意识作为社会意识的一个方面，对社会实践起着积极的作用；计算机虚拟技术的出现与逐渐成熟，开创了人类实践的新境界——虚拟实践。
