  • Patent number: 7293697
    Abstract: The invention relates to a method of transferring data from a drawing device, which while utilizing a position-coding pattern, printed on a physical page, digitally records handwritten information, to an application in a computer system. The drawing device transfers recorded data to a memory in the computer system. A registering unit in the system determines from which part of the position-coding pattern the recorded data originates and activates, on the basis thereof, one or more applications which are registered as “subscribers” to data from this part of the pattern. When an application is activated and thus informed of the existence of new data relevant to the application, the application fetches this data. The fetching of data can be made on the basis of the contents of a page-describing file which defines the layout of the physical page.
