通过心率变异检测判断心理状态评估显示模型建立的研究

摘要

目的 在心率变异检测中,为了更直观地判断被检测者的心理状态而建立检测系统,及时地将检测中的量化数据进行直观的表达.方法 本文用图形方法建立模型,对检测数据进行分析,讨论心理状态从紧张到舒坦过程能够趋于稳定的条件,再用差分方程建立数学模型,对结果进行解释.结果 通过对模型的研究,找到了能够直接观察被检测者心理状态的显示途径.结论 此模型有待进一步完善,以期能够满足对心理检测评估的要求.%Objective In order to estimate psychological states more intuitively in detection of heart rate variability (HRV), the detection system is required to express the quantized data in test directly and timely. Methods This paper first establishes a model through graphic method to analyze the test data and find out the condition of psychological states changing from stressed to comfortable, then stable. Then it uses difference equation to establish a mathematical model to explain the results. Results This paper finds a way to observe the psychological states of the subjects directly. Conclusion This model needs further improvement, to meet the requirement for psychological testing evaluation.
