Electronic pen and method for recording of handwritten information

Abstract

An electronic pen (10) 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 (2, 2'), stores a plurality of digital pen strokes (1, 1') 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 (1), which is processed as graphical information constituting the information to be recorded, and a second type (1'), 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 (16a) indicates, for the processing of the set of digital pen strokes (1, 1'), the working session during which the respective digital pen strokes have been input.

Description

technical field [0001] The present invention relates to the electronic recording of handwritten or hand-drawn information by means of an electronic pen moving in a desired pen motion on at least one substrate. More specifically, the present invention relates to electronic records in which the pen action is registered as a plurality of electronic strokes that are processed as or to be processed as a first type for constituting the recorded graphic information. The second type of instruction for the processing of electronic strokes. Background technique [0002] Input systems for entering handwritten or hand drawn graphic information into a computer are widely used with different types of graphic software, such as CAD programs or web design programs. These input systems include drawing devices and also bases or stands for the latter. The drawing device also includes a device for holding in the user's hand and moving over the substrate with desired pen motions for inputting g...

Problems solved by technology

[0010] The inventors of the present invention have now recognized a problem according to the solution described above: when the user of an electronic pen with selectable attributes starts a new period of generating graphic information with the pen, the user cannot always remember Settings selected from the most recent writing session

Therefore, this process may involve transferring a large amount of information about strokes from the palette page to the server, which then has long transfer times, costs associated with the long transfer times, high power consumption in the pen, and the need for Disadvantages of large storage capacity
