Abstract
Device for processing of information, which device comprises a processor and, connected to the processor, a reading unit for electronic reading of information on a surface, which is provided with a position code which codes a plurality of positions on the surface. The device reads the position code, associates a position code for coded positions within a value area defined on the surface with values in a set of values which includes a plurality of values, and initiates the generation of a control signal whose level is related to a value associated with a read-off position code. Method for processing of position data obtained from said surface. According to the method, the position code is read for a coded position which lies within the value area; the value in the set of values which is associated with the read-off coded position is determined; and the generation of a control signal is initiated, the level of which control signal is related to the determined value. Computer program for processing of position data in accordance with the method, and a product which comprises a surface of the above-mentioned type. Elected for publication: FIG. 1.
