Abstract :
The power of the music in evoking physical reactions has been well studied in literature for healthy and ill subjects. In this study we implemented a plethysmogragh data-acquisition system and analyzed the effect of emotion-evoking videos with audio and without audio on heart rate and average blood flow power. Our experiments showed that the audio plays the key role in variation of heart rate and average blood power with a high significance value (p=4.37×10-5) when compared to visual without audio. The research can be extended further to the development of smart software/applications that predicts user-specific emotion-evoking videos.
