Information management system

摘要

A user unit is described for recording information on a product (1) with a position-coding pattern. The position-coding pattern codes absolute coordinates defining an imaginary surface (100;200). A portion of the imaginary surface (100;200) is divided into subregions (210-212) which contain basic elements (pages 213). The user unit comprises a light-sensitive area sensor (14), which records a two-dimensional image of a surface of the product (1), a memory, and a signal processor (16) to determine a position on the basis of the recorded image. The memory comprises page templates, which define the layout of the pages (213) for different subregions (210-212), said page (213) comprising fields (214-220) for predefined information management. The signal processor (16) is further arranged to identify and initiate the operations which are indicated by fields (214-220) in the template.
