In a memory task which required sustained attention, the positive or negative emotional state of an operator was created by introduction of two different types of feedback in accordance with the number of correct or wrong solutions. Standard and original indices were used for evaluation of the short-term variability of the heart rate (HRV) during performance. Changes in the HRV were observed only in the periods of performance with the failure type of the feedback. These changes reflected stabilization of heart bit-to-bit intervals. The original index of the fast HRV turned to be the most sensitive for testing HRV changes. Human autonomic reactions of such a kind during operator-like activity are known as a predictor for the functional state of dissatisfaction. This confirms the practical importance of application of the HRV indices for testing the ergonomic properties of the systems which control the operator-computer interaction.
在一项需要持续注意力的记忆任务中，根据正确或错误答案的数量引入两种不同类型的反馈，从而营造操作员的积极或消极情绪状态。使用标准指标和原始指标来评估任务执行期间心率变异性（HRV）的短期变化。仅在反馈为失败类型的任务执行期间观察到HRV的变化。这些变化反映了心跳逐搏间期的稳定。快速HRV的原始指标被证明对测试HRV变化最为敏感。在类似操作员的活动中，这种人类自主反应被认为是功能状态不满的一个预测指标。这证实了应用HRV指标来测试控制操作员与计算机交互系统的人体工程学特性的实际重要性。
