Claim Text:
1. A method of tracking velocity of a hand-held paint spray gun operated by a human during actual painting of an object, comprising: placing the object to be painted in an area having at least one wall covered with a constellation of fiducials; storing the three-dimensional location and diameter of each fiducial in memory of a computer; storing a target velocity value in the memory; placing a camera on the spray gun, the camera having a field of view of the at least one wall when the object is being painted; painting the object using the spray gun by motion of the human hand; wherein the field of view of the camera is perpendicular to, or in an opposite direction from, a direction of spray during the painting step; during painting, using the camera to acquire location and diameter data representing the location and diameter of one or more fiducials within the camera's field of view; using the location or diameter data to determine a current velocity of the spray gun; comparing current velocity values to the stored target velocity value; and providing feedback, audio or visual, to the operator representing a relationship of the current velocity to the target velocity value.
