Icons/text/images representing selections areas are placed near a machine-readable image to for retrieving an information item about a product to which the machine-readable image is associated. These selection areas can be visually represented by icons/text/images that inform the user what information will be retrieved or what action will be controlled if selected. A capturing device captures a machine-readable image together with icons/text/images representing selections areas, displays these on the screen for the user to select one of the icons/text/images. The capturing device calculates the coordinates of the selection relative to the machine-readable image using a unit of distance and perspective correction derived from the machine-readable image. These coordinates are provided to an information server associated with the machine-readable image which in turn provides the information associated to the coordinates to the capturing device.
