Abstract: A method is disclosed for correcting deviations in a production process of an article. Initially, measured 3D surface coordinates of a first article are obtained and used to create a virtual image of the first article that is displayed on a display apparatus that is fastened to the user's head.

The user is then able, via a gesture (e.g., hand movement) or head movement, to select a particular region of deviation and control the desired corrective action to be performed on subsequently produced articles. The present method thereby enables the experienced user to subjectively select the region(s) requiring correction action and the degree and type of corrective action to be taken.
