人机操作界面中不同效应器（手或脚）对被交叠作业的干扰作用

实验结果提示在高速复杂人机系统操作界面的优化设计中，采用不同的效应器（手或脚）未降低，更不能消除交叠作业的瓶颈干扰，被交叠作业的绩效未被提高。但是，降低反应选择复杂度可有效提高被交叠作业的绩效，作业反应选择复杂度与交叠作业瓶颈干扰程度成正比。

The Effects of Response Modality (Foot or Hand) on Overlapped Task in Man Machine Operation Interaction

For the design of man machine operation interaction in the complexity and speed man machine system the results showed, that using different response modality (foot hand) did not eliminate and reduce PRP interference, and could not raise the performance of overlapped task. But lowering the complexity of selecting response could raise the performance of overlapped task. The grade of complexity of selecting respose was in direct proportion to the degree of PRP (psychological refractory period) interfe rence.
