Description

<p>Electrocardiogram(ECG) is often used for affective evaluation using biosignals. However, adhesive-based sensors are difficult to use on daily basis and may affect participants’ emotion. In this study, we measured blood pressure pulse (BVP) using wearable sensor, and compared physiological indexes between calculated from ECG and BVP during floor cleaning task. As the results, we found the tendency of physiological indexes calculated from BVP. For example, BVP-based RRI had large dispersion. Approximately 20% of data showed a strong correlation between indexes calculated from ECG and BVP. Our results suggested that BVP measurement would be useful if the effects of body movement were removed.</p>
