ABSTRACT:
An intention identification method, i.e., a method of tracking movement of an object for the purpose of determining intention in order to operate a computer, includes the steps of processing a pattern of an object captured by a video camera and converting the pattern into a plurality of pixels, analyzing a variation trend of the pixels based on variation of the pixels in any direction relative to a preset geometric center, and comparing a quantity representing the direction and moving amount of the pixels to a characteristic curve, the characteristic curve being formed by a non-activate region set with respect to the center of the pixels, and an activate region also set with respect to the center of the pixels and which is larger than the non-activate region.
