PROBLEM TO BE SOLVED: To provide a method and a device suitable for quantitatively grasping a walking state of an animal including the direction and the degree of imbalance by visually displaying three-dimensional acceleration data sampled for grasping the walking state in an easily recognizable way. SOLUTION: Among three components of R,Θ,Z of acceleration vector data in a columnar coordinate system of R,Θ,Z, during an action of the animal, obtained by columnar coordinate conversion, the R- or Z- component is used to form a ranking (order) table. Data of the R- or Z-component (acceleration vector) before and after a focusedΘ-value that provides the R- or Z-component in an upper place in the ranking are associated with angles, and the animal action is presented by a circle of which circumference is allotted with the angles and the R- or Z-axis perpendicular to the circumference.
