Abstract
The invention relates to a method, a computer program product and a device for arranging a first and a second coordinate area relative to each other, which first and second coordinate areas are coded on a first and a second surface by a position-coding pattern. The method comprises the steps of receiving an electronic representation of a continuous line that has been drawn over the surfaces while the position-coding pattern on these was recorded, and creating an association between the first and second coordinate areas, based on a direction in which the line was drawn over a discontinuity in the Position-coding pattern, a first association being created if the line was drawn in a first direction and a second association being created if the line was drawn in a second direction.
