Abstract: A document editing method includes transferring document information to a printing device capable of printing the document information on a surface coded with a position-coding pattern. Editing information is received from a reading device capable of reading position information from the position-coded surface.
Abstract: An information management system comprises a product provided with a position code a digital pen capable of reading the position code, a look-up unit, and a plurality of databases connected to the digital pen via a first communication path. The databases include a pen database, a position database, and an event database. The information management system also includes an interface unit, separate from the look-up unit, and used to provide access to the pen database, the position database, and the event database via a second communication path that is separate from the first communication path.
Abstract: A computer-implemented method is designed for on-demand printing on digital printers of a coding pattern to code data on a surface. The coding pattern comprises a plurality of parallel number sequences which represent different rotations of a cyclic number sequence. The method could involve retrieving a digital representation of the coding pattern, and identifying the rotations therein to derive shift information which designates a phase difference between each rotation and the cyclic number sequence. In the printing operation, all the different rotations may be represented by the cyclic number sequence embodied as at least one code block image. This code block image is repeated in accordance with the shift information to form a printable image in the printer.
Abstract: A method and a computer program are described for developing a product (110), and services associated with the product, which product has at least one activation area (308) which is provided with a position code (403) that codes at least one position on an imaginary surface (601), which position causes a device (710) that detects the position code (403) to initiate an operation that utilizes information recorded by the device (710). A digital representation of at least part of the product comprising image points is produced, each image point in the digital representation of the activation area (308) corresponding to a position on the imaginary surface (601). A digital template that can be used for making the digital representation of the product is also described.

Abstract: The present invention relates to a method, a system and a computer-readable medium storing computer-executable components for authenticating a digital pen. The invention is based on the idea that a paper look-up server issues an authentication receipt used by a service handler to authenticate a digital pen. The authentication receipt comprises such information that the service handler can use it to authenticate the digital pen without having to communicate with the paper look-up server.
