Human characteristics as compared with the machine performance were summarized and discussed as to the signal reception, control operation, information processing, endurability, reliability, communications as well as system efficiency and others. Stress is laid on the facts that every operator acts as a unit, that he has adaptability but is succeptible to strenuous, monotonous or critical state. Need of humanistic considerations was also emphasized.
The mechanization and automation of the system task should be promoted on the basis of a wide vision for safer, effective dut not monotonous and more “human” tasks.
