Claim 0:
1. A method for assisting object control, comprising the steps of:
specifying a trace of a motion made by a user on the basis of data or a plurality of frames acquired by a camera,
determining a dominant component capable of dominantly representing the motion made by the user with reference to the trace of the motion;
dynamically establishing a motion reference spatial coordinate system with reference to the dominant component; and
recognizing 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 in the dynamically establishing step, 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.
