1. An inspiration model device comprising: a spontaneous emotion unit that prepares, as data, a plurality of emotion states in advance, which is obtained by modeling human emotions, and simulates creation of a human spontaneous emotion by causing state transitions to occur repeatedly between said emotion states according to an operation process representing a stochastic model of the Schrödinger equation; a knowledge database that simulates a human inspiration source, which is influenced by sensibility, by classifying externally collected knowledge data depending on degrees of correlation with said emotion states and accumulating said knowledge data; and a conception unit that, when receiving an external input, simulates human conception by combining said external input with one of the emotion states of said spontaneous emotion unit and searching said knowledge database for related knowledge data using, as a search key, one of the combination and a state of interference produced by the combination.
