Disclosed is a method for determining an emotion of a computer, comprising the steps of: mapping a plurality of emotions to different coordinates on a plane including a first axis and a second axis; dividing the plane on the basis of the plurality of mapped coordinates; using a divided plane as bottom surfaces, and generating a plurality of cones having a height in a third axis direction perpendicular to the plane; determining first coordinates included in a three-dimensional emotion space formed of the first axis, the second axis, and the third axis; and determining an emotion corresponding to the first coordinates, wherein, in the emotion space, coordinates included in the plurality of cones correspond to the emotion mapped to the mapped coordinates included in the bottom surfaces of the plurality of cones, and the size of a third axis direction component of the coordinates included in the plurality of cones is proportional to the depth of the emotion corresponding to the coordinates included in the bottom surfaces of the plurality of cones.
