Recently, the number of people suffering from the aftereffects of COVID-19 is increasing, and in order to respond to this, the aftereffect clinic facilities are being prepared, but research on indirect or direct treatment or healing in a residential space where people spend the most time is still insufficient. Therefore, the purpose of this study is to explore the healing design method of a residential space through pulse wave (HRV) and emotional evaluation. The study conducted a questionnaire and experiment on 20 people centering on two pairs of residential space images showing differences in lighting, first investigated the 'attention resource' and the 'emotional vocabulary using the SD method through the questionnaire, and secondly, the 'stress index' and the 'RMSSD index' were investigated through the pulse wave experiment using a ubiquitous device. As a result of the study, it can be seen that attention resources change according to the difference in lighting, and in particular, the element of 'contrast' was actively found. In addition, in 'Images 2 and 4', the design using the healing elements of 'shape', 'color', and 'contrast' showed high psychological stability. Therefore, the healing design method in a residential space may be the most effective method considering 'shape', 'color', and 'texture' to induce 'warm' sensitivity.
