The present study examined the validity of a novel physiological measurement technology called transdermal optical imaging (TOI) technology at assessing basal stress. This technology conveniently, contactlessly, and remotely measures facial blood flow changes using a conventional digital video camera. We compared data from TOI against the pulse data collected from the FDA approved BIOPAC system. One hundred thirty-six healthy adults participated in the study. We found that TOI measurements of heart rate and heart rate variability (HRV), which reflects basal stress, corresponded strongly to those obtained from BIOPAC. These findings indicate that TOI technology is a viable method to monitor heart rate and HRV not only accurately but also conveniently, contactlessly, and remotely. Further, measures of HRV obtained via TOI serves as a valid index of basal stress. Potential applications of this technology in psychological research and other fields are discussed.
本研究检验了一种名为透皮光学成像（TOI）技术的新型生理测量技术在评估基础应激方面的有效性。该技术使用传统数码摄像机，方便、非接触且远程地测量面部血流变化。我们将TOI数据与从美国食品药品监督管理局（FDA）批准的BIOPAC系统收集的脉搏数据进行了比较。136名健康成年人参与了该研究。我们发现，反映基础应激的心率和心率变异性（HRV）的TOI测量结果与从BIOPAC获得的结果高度相关。这些发现表明，TOI技术不仅是一种准确、方便、非接触且远程地监测心率和HRV的可行方法。此外，通过TOI获得的HRV测量结果可作为基础应激的有效指标。讨论了该技术在心理学研究和其他领域的潜在应用。
