An information management system is intended for management of digitally represented information which is associated with absolute positions on an imaginary surface (). The imaginary surface () contains at least two regions (-), each of which is dedicated to predetermined management of the digitally represented information. In the system the management of the digitally represented information is carried out on the basis of the region affiliation of the absolute positions associated with the information. The system is suitably based on use of a position-coding pattern which defines the imaginary surface () and which in parts is applicable on different bases. The system makes possible both digital recording of information and control of how the information thus recorded is to be managed. A database, a method for management of information, a method for compiling a pattern layout, a product and use are also described.

General information management system

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.

Processing of documents

The invention relates to a method for generating a printout of a section of a global position-coding pattern in a system comprising a computer unit and a printer unit connected to the computer unit. The method is characterized by the steps of generating in the computer unit boundary information that describes the boundaries of the section in the global position-coding pattern; transmitting the boundary information from the computer unit to the printer unit; generating graphical information in the printer unit by means of an algorithm that defines the global position-coding pattern and on the basis of the boundary information, which graphical information describes pattern symbols in the section; and printing out the graphical information on a base by the printer unit.

Method and device for preparing a printout of a position-coding pattern

A combined position and information code, which could be applied on a base, comprises a position code, which comprises a plurality of coding marks and which codes a plurality of positions. Each position in the position code is coded by a predetermined number of coding marks. Groups of coding marks are defined in the position code. The number of coding marks in each group is larger than the predetermined number of coding marks. At least some of the coding marks in each group are used for coding an information item. When decoding the combined code, part areas of the combined code are imaged. A position is decoded from each imaged part area, whereas the information item has to be decoded from at least two part areas.

Coding and decoding methods and apparatuses

The invention relates to a method in creating a two-dimensional symbol pattern which may be utilized to determine a position in a large area covered by the pattern, for example for recording handwritten information by means of a pen-like instrument. The invention is useful for creating a symbol pattern having desired properties, namely that any sufficiently large observed part of the pattern is unique, enabling an unambiguous determination of position. The symbol pattern is based on a non-repeating sequence of symbol values Sthat each corresponds to a fixed linear combination of the coefficients of the monomials in xmod P(x), where P(x) is any polynomial of degree n in the field F. The symbol pattern is generated by folding the sequence according to a wrapping scheme. The invention also relates to methods and systems for finding the position of a group of observed symbol values in this symbol pattern and computer program products performing the methods.

A system for information management comprises a central unit and a plurality of user units which are arranged to record information and send the information to the central unit. Particulars are stored in the central unit about a plurality of regions, each of which represents an area on at least one imaginary surface. One of the user units records information which comprises at least two coordinates and sends the information to the central unit. When the central unit receives the information from the user unit, it identifies to which region the coordinates belong and determines how the information is to be managed, based on the region affiliation.

Centralized information management based upon position information

A method and a computer program are described for developing a product (), and services associated with the product, which product has at least one activation area () which is provided with a position code () that codes at least one position on an imaginary surface (), which position causes a device () that detects the position code () to initiate an operation that utilizes information recorded by the device (). 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 () corresponding to a position on the imaginary surface (). A digital template that can be used for making the digital representation of the product is also described.

Method for making a product

Method for printing a global position-coding pattern

A product has a coding pattern on its surface. The coding pattern may include symbols representing at least two different values and where each symbol comprises a raster point and at least one marking. The raster point is included in a raster that extends over the surface and the value of each symbol is indicated by the placement of the marking in relation to the raster point. The markings may each have a spatial extent that, in combination, may at least partially form the image.

Apparatus and methods relating to image coding

A product for electronic transmission of handwritten information, a user unit for recording and sending the information, and a computer program for controlling a user unit are disclosed. The product may include at least one writing area for the handwritten information and an address area indicating an address to which the handwritten information is to be sent. A position-coding pattern in the form of a plurality of symbols may be reproduced in the writing area, an arbitrary position area of a predetermined size of the position-coding pattern unambiguously defining a position on the product. The address area may include an address-coding pattern with a plurality of symbols, an arbitrary address portion of a predetermined size of the address-coding pattern unambiguously defining part of the address.

Device and method for communication

The invention relates to a method of effecting in a computer system transmission of data between a digital user unit and a computer resource, the user unit being adapted to detect positions on a base which is provided with a part of a global position-coding pattern. The invention is characterized in that a request for access to a computer resource is received, using a first protocol stack, by the computer system from the user unit, said request containing a position indication, relating to which part of the global position-coding pattern that has been detected by the user unit. The computer system gains access to a computer resource using a communication mode and a second protocol stack. The communication mode is chosen based on the position indication. Only the second protocol stack comprises TCP/IP functionality, so that only data transmitted between the computer system and the computer resource comprises routing information.

Method for transmitting information

In an input unit arrangement use is made of an input unit in combination with a mouse pad, which is provided with a position-coding pattern which codes coordinates for a plurality of positions on the mouse pad. Areas on the mouse pad are provided with subsets of the position-coding pattern which are dedicated to different functions. The input unit can be caused to optically read the position-coding pattern, whereupon the input unit arrangement decodes the positions that are coded locally on the mouse pad. By placing the input unit within the various areas on the mouse pad, a user can make the input unit arrangement carry out various functions, such as automatically switching from a mouse function, in which a cursor is controlled on a display on the basis of the decoded position, to an input function, in which information via the input unit is inputted into an electronic device, such as a computer, telephone, PDA etc. A method for controlling the input unit arrangement is also described, as is also use of an absolute position-coding pattern.

Input unit arrangement

A system and method are disclosed for controlling access to an access-protected unit. A pair of coordinates may be read from a base, such as a card, using a digital pen. The system may then check if the pair of coordinates are within a coordinate area belonging to an authorized user. If so, access may be granted to the authorized user to the access-protected unit or to specific programs or functions of the access-protected unit.

Secured access using a coordinate system

A product is provided with a coding pattern, which codes position information in the form of coordinates for a plurality of points on the product with the aid of a plurality of marks belonging to each point. The marks have a first parameter which varies for coding of the position information. The marks additionally have a second parameter which varies for coding of further information in the coding pattern. A method and a device for coding of the coding pattern and a method and a device for decoding of the coding pattern are also described.

Coding pattern

A system for information management consists of a product, for instance a notepad sheet, which has a writing surface () with a position code (), which codes a plurality of positions on the surface, and a device, which is adapted to record the information which is being written on the writing surface by detecting the position code. Moreover, on the product there are a number of activation icons (). When such an activation icon is detected by the device, the device initiates a predetermined operation which utilizes the recorded information. Such an operation can, for instance, consist of sending the recorded information to an indicated address. A product, a device, a method and a computer program for information management are also shown.
