Abstract: A method and system provide light to project to an operation space so that a received image from the operation space will include, if an object is in the operation space, a bright region due to the reflection of light by the object, and identify a gesture according to the variation of a barycenter position, an average brightness, or an area of the bright region in successive images, for generating a corresponding command. Only simple operation and calculation is required to detect the motion of an object moving in the X, Y, or Z axis of an image, for identifying a gesture represented by the motion of the object.
