Breathing could be one of the effective animating elements for expressing emotions of living things. The main aim of this study is to expand this concept to abiotic things and to propose a method for generating animations expressing emotions through making them breathe in a pseudo manner. To begin with, we carried out a preliminary evaluation experiment regarding the emotional expressiveness of abiotic breathing animations, and we confirmed that several kind of emotion can be expressed even by the breathing motions applied to the abiotic object. When making the novel style of breathing animations, we specified a 2D ROI from an original image by surrounding it with a contour line, and then imposed a triangular mesh on the abiotic object. Then, from the resulting mesh, we extracted the submesh expressing the region of lungs, to which the operation of swelling and shrinking is applied. We succeeded in the effective expression of changes in internal state of individual abiotic objects and atmospheric situations suggested by different internal states of multiple objects.
