Electronic pen and method for recording of handwritten information
First Claim
1. An electronic pen for recording of handwritten or hand-drawn information, comprising a control unit;
- and a memory, wherein the control unit is arranged to register pen movements across at least one base, to store a plurality of digital pen strokes in the memory as a function of said movements, and to supply a set of the digital pen strokes for processing, and wherein the digital pen strokes include a first type, which is intended to be processed as graphical information constituting said information to be recorded, and a second type, which is intended to be processed as instructions for the processing of digital pen strokes of the first type, the electronic pen further comprising;
session-determining means adapted to detect a current working session of the pen, wherein the control unit is arranged to indicate, for the processing of said set of digital pen strokes, the working session during which the respective digital pen strokes have been input.

Abstract
An electronic pen for recording of handwritten or hand-drawn information has a control unit and a memory. The control unit registers pen movements across at least one base, stores a plurality of digital pen strokes in the memory as a function of said movements, and supplies a set of the digital pen strokes for processing. The digital pen strokes include a first type, which is processed as graphical information constituting the information to be recorded, and a second type, which is processed as instructions for the processing of digital pen strokes of the first type. The electronic pen also has session-determining means adapted to detect a current working session of the pen. The control unit indicates, for the processing of the set of digital pen strokes, the working session during which the respective digital pen strokes have been input.

19. A system for electronic recording of handwritten or hand-drawn information, comprising:
-
an electronic pen which is intended to be moved in desired pen movements across at least one base and to register the pen movements as a plurality of digital pen strokes; and
a processing device for receiving registered digital. pen strokes from the electronic pen, the digital pen strokes including a first type, which is processed by the processing device as graphical information constituting said information to be recorded, and a second type, which is processed by the processing device as an indication of a property of digital pen strokes of the first type, the electronic pen further comprising;
session-determining means adapted to detect a current working session of the pen;
wherein, upon transmission of the digital pen strokes to the processing device, the electronic pen is arranged to indicate during which working session the respective digital pen strokes have been input; and
wherein, upon processing of the digital pen strokes, the processing device is arranged to detect that a certain digital pen stroke is indicated as having been input during a different working session than a preceding digital pen stroke and, as a consequence of this, to restore the property for successive digital pen strokes of the first type to an initial or default state.

21. A method for recording of handwritten or hand-drawn information originating from the pen movements of an electronic pen which are registered as digital pen strokes, wherein the digital pen strokes include a first type, which concerns graphical information constituting said information to be recorded, and a second type, which concerns instructions for the processing of digital pen strokes of the first type, the method comprising the steps of:
-
a) detecting the working session of the pen during which the respective digital pen strokes are recorded, b) determining the working session(s) during which a plurality of digital pen strokes of said first type were recorded; and
c) supplying for processing only such digital pen strokes of said second type which have been registered during the working session(s) determined in step b). - View Dependent Claims (22, 23)

24. A method for processing of handwritten or hand-drawn information in the form of a plurality of digital pen strokes which have been registered by the pen movements of an electronic pen and which include a first type, which concerns graphical information constituting said information to be recorded, and a second type, which concerns an indication of at least one property of digital pen strokes of the first type, the method comprising the steps of processing a set of recorded digital pen strokes as follows:
-
a digital pen stroke of the second type determines a current property of digital pen strokes of the first type;
digital pen strokes of the first type are assigned the current property; and
if a certain digital pen stroke is indicated as having been recorded during a different working session of the electronic pen than a preceding digital pen stroke, the current property is reset to an initial or default state. - View Dependent Claims (25, 26)
