The purpose of this study is to validate the ability of the digital device as a self-assessment tool for pleasant and unpleasant emotional experiences. We examined the relationship of subjective ratings of the pictures by using a portable touch panel with a slider, with physiological responses (i.e., heart rate: HR). The results indicated that the touch panel ratings for unpleasant pictures changed simultaneously with the HR, while those for pleasant pictures indicated delayed responses to the HR. The findings of this study implicated the usefulness of the touch panel device to investigate emotional experiences on various situations outside the laboratory.
