Abstract:
A system and a method are described for reading data from a document and a method of detecting data. To read data which are present in volatile (i.e. time-variable) and weakly structured documents (e.g. HTML pages), a system with a computer having indicator and input means for operation by a user is proposed. The computer can access at least one document. The computer runs a program by which at least one first input by the user is processed with which a data range of the document to be read is fixed. The program automatically creates an extract instruction for reading the fixed data range. The extract instruction can, for example, be stored. When executing the extract instruction, the fixed data range of the document is read. This can be iterated with time intervals.

Abstract:
The invention describes a method of determining the motion of a pointing device (2), wherein the method comprises the steps of aiming a pointing device (2) comprising a camera (3) in the direction of a target area (A) and generating images (4) of the target area (A) aimed at by the pointing device (2) while also obtaining a sequence of relative motion vectors (V 1 , V 2 , V 3 , V 4 ) pertaining to the motion of the pointing device (2), during an image frame time between images (4). The images (4) are transmitted with the corresponding relative motion vectors (V 1 , V 2 , V 3 , V 4 ) to a control interface (20) where they are interpreted to determine the motion of the pointing device (2).
