Loneliness is a subjective, unwanted feeling of lack or loss of companionship. Loneliness can be understood as an emotional experience: a perceived shortcoming in the quantity or quality of one's existing relationships. Through the interactive space design, the two emotions of love and loneliness enable people who are troubled by loneliness to release their psychological pressure and actively face social life; people who are not troubled by loneliness can understand and sympathize with the lonely people around them.
