Classification: CPC G | IPC G

Claim 6:
7. A system for assisting object control, comprising:
a spatial coordinate system management unit configured to determine a dominant component capable of dominantly representing a motion made by a user with reference to a trace of the motion, and to dynamically establish a motion reference spatial coordinate system with reference to the dominant component; and
a motion recognition unit configured to recognize an intention of the motion with reference to at least one of the trace specified with respect to the motion reference spatial coordinate system and properties of the trace,
wherein the trace of the motion made by a user is specified on the basis of data or a plurality of frames acquired by a camera,
wherein a direction and a size of the dominant component are determined from the trace, and a number of dimensions of the motion reference spatial coordinate system and a reference coordinate axis of the motion reference spatial coordinate system are determined on the basis of the determined direction and size of the dominant component,
wherein the number of dimensions is determined on the basis of a number of dominant components whose size is not less than a threshold level, and
wherein the reference coordinate axis is determined on the basis of a direction of a dominant component whose size is not less than a threshold level.
