机器的出现,给科学家提出了人一机关系问题,从而为工效学(有的国家又称为人体工程学或人的因素工程学)的产生奠定了基础。今天,计算机的广泛应用,又提出了人一计算机关系问题。计算机虽然也是一种机器,但是同普通的机器有着本质的区别,因此解决人一计算机关系问题不能用传统的工效学方法,而应该用新的概念,新的理论和新的研究方法。这就是认知工程的研究范畴。
The advent of the machine presented scientists with the problem of human-machine relations, which laid the foundation for the emergence of ergonomics (some countries are also called ergonomics or human factor engineering). Today, the widespread use of computers raises the question of human-computer relations. Although computer is also a kind of machine, it has the essential difference with common machine. Therefore, we should not use traditional ergonomics to solve the problem of human-computer relationship, but should use new concept, new theory and new research method. This is the area of cognitive engineering research.
