System, game device, method, and program for determining motion sequence

A game device for providing a game that is made to proceed, with a virtual object being disposed in a virtual space, the game device comprising:

• a motion database that stores each of a plurality of motion sequences in association with a plurality of sub-features of a plurality of types, each of the plurality of sub-features of the plurality of types associated with a respective motion sequence among the plurality of motion sequences being a feature related to the respective motion sequence;
• a sub-feature extraction unit that extracts a sub-feature(s) of a predetermined type(s) from a plurality of features related to the virtual object;
• and
• a motion-sequence determination unit that determines one motion sequence from the motion database by comparing each of the sub-feature(s) of the predetermined type(s) extracted by the sub-feature extraction unit with the plurality of sub-features of the plurality of types in the plurality of motion sequences stored in the motion database,
• wherein the motion-sequence determination unit calculates, for each type of the sub-feature(s) extracted by the sub-feature extraction unit, a degree of similarity between a sub-feature of a predetermined type and sub-features of the predetermined type in the plurality of motion sequences stored in the motion database to produce a plurality of calculated degrees of similarities, and
• wherein the motion-sequence determination unit determines one motion sequence based on the plurality of calculated degrees of similarities.

A method for determining a motion sequence of a virtual object in a virtual space, the method comprising:

• extracting a sub-feature(s) of a predetermined type(s) from a plurality of features related to the virtual object;
• determining one motion sequence from a motion database by comparing each of the sub-feature(s) of the predetermined type(s) with a plurality of sub-features of a plurality of types in a plurality of motion sequences stored in the motion database,
• wherein the motion database stores each of the plurality of motion sequences in association with the plurality of sub-features of the plurality of types, each of the plurality of sub-features of the plurality of types associated with a respective motion sequence among the plurality of motion sequences being a feature related to the respective motion sequence;
• calculating, for each type of the sub-feature(s) that are extracted, a degree of similarity between a sub-feature of a predetermined type and sub-features of the predetermined type in the plurality of motion sequences stored in the motion database to produce a plurality of calculated degrees of similarities;
• and
• determining one motion sequence based on the plurality of calculated degrees of similarities.
