A rotating electric machine is comprised of a stator having a stator core and a stator coil wound around the stator core, the stator core having at least two tip portions, and a rotor having a rotor core and a plurality of permanent magnets provided in the rotor core, the rotor being rotatable relative to the stator. A virtual force that acts on a focused lattice point in the equipment-independent color space is defined, and a position at which the focused lattice point is located in a steady-state in which the virtual force acts on the focused lattice point is calculated. Further, user interface elements are mapped to the business documents.
