无人机操作主观心理负荷测评与心率数据比较

为探究在无人机实操试验的心理负荷测量中主观量表与心率测评工具的性能，招募14名从未接触过无人机操作的被试者，在参加飞行操作培训后进行4种不同难度的无人机飞行操作情景试验；使用Polar V800监测被试者试验过程中的心率变化，并在试验结束后采用NASA-TLX，MCH，SWAT 3种主观量表进行评分，以比较飞行难度间各指标的性能差异。结果表明:随着难度增大，呈现出主观评分与MEANHR增大，MEANRR减小的趋势；所有测量指标均能区分大部分难度差异，主观量表之间存在正相关性且收敛效度良好，量表评分与绩效表现之间关联性较强；主观量表与心率指标能够对无人机操作中的心理负荷进行有效的测量，这为未来无人机操作心理负荷的预测提供测量基础。

Comparison of subjective mental workload evaluation and heart rate data of UAV operation

In order to explore the performance of subjective scale and heart rate evaluation tool in the metal workload measurement of the UAV operation test,14 subjects without UAV operation experience were recruited,and after participating in the flight operation training,four types of UAV flight operation scenario tests with different difficulties were carried out.The Polar V800 was used to monitor the participants’ heart rate changes during the test,and 3 subjective scales of NASA-TLX,MCH,SWAT were used to score after the test,so as to compare the performance difference of each index between the flight difficulty.The results showed that as the difficulty increased,the subjective score and MEANHR increased,and the MEANRR decreased.All the measurement indexes could distinguish most difficulty difference,and there was a positive correlation between the subjective scales with good convergence validity.There was a strong correlation between scale scores and performance.The subjective scales and heart rate indexes could effectively measure the mental workload in the UAV operation,which provides a measurement basis for predicting the mental workload of UAV operation in the future.
