1. An apparatus for evaluating equipment operability which evaluates operability of equipment, comprising: a physique management unit managing body information about a human body model as a copy of a shape of a human body; a visual identification management unit managing visual identification information as information about a sight line of the human body model; a target management unit managing a human body part of the human body model and a target position to which the human body part is to be moved as target information; a supposed operation setting unit setting a plurality of supposed operations each of which is a supposed operation of the equipment as associated with the visual identification information and the target information; a posture calculation unit calculating a posture of the human body model which performs the set supposed operation based on the body information about the specified human body model and at least the target information corresponding to the supposed operation set by the supposed operation setting unit; a simulation unit arranging an equipment model as a copy of a shape of the equipment and the human body model having the posture calculated by the posture calculation unit in a three-dimensional virtual space, and displaying a view image as an image of the three-dimensional virtual space from a point of view of the human body model having the posture; an operation information input unit inputting operation information about the equipment model in the view image; an operation recording unit recording an operation result of the equipment model based on the operation information about the equipment model input by the operation information input unit; and an operability evaluation unit evaluating the operability of the equipment based on the recorded operation result of the equipment model.
