Abstract
A digital writing system according to one embodiment of the present invention captures handwritten gestures in addition to text and patterns. It may include, among other things, a digital pen, special erasable ink and paper, and application software for the managing of captured files with a corresponding user interface. A digital pen according to one embodiment of the present invention may include character recognition subsystem, function control subsystem with selection mechanisms, a processor subsystem, memory subsystems, and wired or wireless communication subsystems. In addition, embodiments of a digital pen according to the present invention may include additional functional features including, for example, a user notification (e.g., alarm) feature, a digital camera feature, voice recording and recognition features, calendar features, calculator features, biometric sensor features, and the like.

7. A digital pen device for capturing handwriting gestures and converting them into digital data for transmission to a computer system, the digital pen device comprising:
-
a pen barrel;
a character recognition module housed within the pen barrel for capturing the handwriting gestures;
a processor housed within the pen barrel and coupled to the character recognition module for converting the captured handwriting gestures into a first computer readable data;
a function selection module at least partially housed within the pen barrel and coupled to the processor, the function selection module including function selection mechanisms for selecting a formatting function to associate with the handwriting gestures, the processor furthered configured to associate the formatting function with the handwriting gestures as formatting information and to convert the formatting information into a second computer readable data; and
a communication module at least partially housed within the pen barrel and coupled to the processor for transmitting the first and the second computer readable data to the computer system. - View Dependent Claims (8, 9, 10, 11, 12, 14)

15. A method for digitally capturing handwriting gestures with a digital writing system comprising a digital pen device, the method comprising:
-
capturing handwriting gestures produced by a user on a writing surface using the digital pen device;
converting the captured handwriting gestures into computer readable image data;
receiving a formatting function selection signal from a selection mechanism located on the digital pen device indicating a format for application to at least a subset of the handwriting gestures;
in response to receiving the formatting function selection signal generating formatting data to apply to the computer readable image data corresponding to the subset of the handwriting gestures; and
transmitting the computer readable image data and the formatting data to a host system. - View Dependent Claims (16, 17, 18, 19, 20)
