Abstract
Abstract Disclosed is the system for editing characters and graphics through a computer with a data entered via the pen point entry procedure. The system comprises the input device for entering the data, the data processor for processing the data entered, the data storage for storing the data entered, the display device for displaying the display data, and the pen through which the data is entered. With this system, information containing characters and graphics as well as the editing request in a mixed manner can be entered through pen points without paying any consciousness to the entry of commands, as well as the characters, graphics and the commands can be subjected to processing.

Independent Claim
172 words
A system for editing a character or a graphic through pen point entry of data in a computer system having a pen point entry means, comprising: a character recognizing means for recognizing characters; a graphic recognizing means for recognizing graphics; an editing request recognizing means for recognizing editing requests; an input deciding means for deciding whether the data entered through said pen point entry means is a character, a graphic or an editing request according to an order of priority previously established and corresponding to characteristics of the data entered through said pen point entry, and deciding a suitable recognizing means from said character, graphic and editing request recognizing means on basis of a classification condition; a storage means for storing a result of recognition by a suitable recognition means decided by said input data deciding means; and a display means for displaying said result, and wherein the order of priority provided for each of said character recognizing means, said graphic recognizing means, and said editing request recognizing means is dynamically changed.
Claim 2
Independent Claim
172 words
A system for editing a character or a graphic through pen point entry of data in a computer system having a pen point entry means, comprising: a character recognizing means for recognizing characters; a graphic recognizing means for recognizing graphics; an editing request recognizing means for recognizing editing requests; an input deciding means for deciding whether the data entered through said pen point entry means is a character, a graphic or an editing request according to an order of priority previously established and corresponding to characteristics of the data entered through said pen point entry, and deciding a suitable recognizing means from said character, graphic and editing request recognizing means on basis of a classification condition; a storage means for storing a result of recognition by a suitable recognition means decided by said input data deciding means; and a display means for displaying said result, and wherein the order of priority provided for each of said character recognizing means, said graphic recognizing means, and said editing request recognizing means is dynamically changed.
Claim 3
Dependent Claim
59 words
A system according to claim 1, wherein each of said character recognizing means, said graphic recognizing means, and said editing request recognizing means is provided with an order of priority when said data drawn and entered through said pen point entry means is determined whether said data is a character data or a graphic data or an editing request.
Claim 4
Dependent Claim
58 words
A system according to claim 2, wherein the order of priority of said character recognizing means, said graphic recognizing means, and said editing request recognizing means is determined with reference to a trace of said data entered through said pen point entry means or said input data deciding means for recognizing the result of said decision stored previously.
Claim 5
Dependent Claim
77 words
A system according to claim 2, wherein: all of said character recognizing means, said graphic recognizing means, and said editing request recognizing means are operated in a parallel fashion for recognizing said data entered through said pen point entry means as an object of recognition; all results of recognition obtained by said recognizing means are compared; and said recognizing means having the highest order of priority is adopted from the most acceptable or reasonable results of recognition.
Claim 6
Dependent Claim
36 words
A system according to claim 1, wherein the order of priority is previously established according to a first classification corresponding to a kind of input data and a second classification representing details of the first classification.
Claim 7
Independent Claim
235 words
A method for editing a graphic using a pen point entry means; comprising: a character recognizing step for recognizing a character data; a graphic recognizing step for recognizing a graphic data; an editing request recognizing step for recognizing a command for an editing request; an input data deciding step for deciding whether the input data entered through said pen point entry means is a character, a graphic or an editing request according to an order of priority previously established and corresponding to characteristics of the data entered through said pen point entry, and deciding the order of priority of each of said recognizing steps on basis of a classification condition; a selecting step for selecting the recognizing step with the highest order of priority from said character, graphic and editing request recognizing step on basis of the result of said input data deciding step; a recognition result deciding step for deciding whether the result of the recognition executed by said selecting step is suitable; a storing step for storing a result of said recognizing step when the result of a recognition is suitable; and a repetition step for repeating the recognition of said input data using by the recognizing step with the next highest order of priority until the result of the recognition is suitable, and wherein said order of priority of each recognizing step provided by said input data deciding step is dynamically chanced.
