(一)前言在人机系统中,操纵者和机械之间的一个重要联系是视觉信息的传递。人机系统可以是开放的,如在监视任务中,这时信息仍处在视觉子系统中,仅有的运动动作是眼球运动。在视野方面,眼睛可从接收10亿比特/秒的信息,而神经每秒只能传递几百万比特。至于中枢神经系统每秒仅可处理几十比特的信息(1970年Mc Cormic)。由于直接监视相关的大脑区域尚不可能,因此,只能从眼球运动记录中研究所寻求的信息有多少,所寻求
(A) Preface In the man-machine system, an important link between the manipulator and the machine is the delivery of visual information. Man-machine system can be open, as in the surveillance task, when the information is still in the visual subsystem, the only movement is the eye movement. In the field of view, the eye can receive 1 billion bits per second of information, and nerves can only pass millions of bits per second. The central nervous system can handle dozens of bits of information per second (1970 Mc Cormic). Since it is not possible to monitor the relevant brain area directly, it is only possible to study how much of the information sought from the eye movement record,
