Layer editing method and apparatus in a pen computing system
First Claim
1. An apparatus for executing a layer editing command in a pen computing system, the apparatus comprising:
- a display screen for displaying at least original text to be edited;
a layer generating means for generating at least one transparent layer having a layer identifier in response to a layer editing command;
a memory for storing trail information written on said display screen, and for storing positional information corresponding to said trail information; and
a control section for displaying said generated transparent layer over said original text, sensing a pen input, outputting a trail of said sensed pen input on the display screen, and storing said trail information and said positional information in said memory.

Abstract
An editing apparatus and an editing method in a pen computing system using a whole display screen as an input window. Edited information written or drawn by a user on a transparent layer, which is displayed over original text, is stored as a picture or translated into computer-processible recognition data. Each transparent layer has a layer identifier. The user can display multiple layers over the original text by selecting layer identifiers to reflect layer information in a picture form or in a computer code form. The layer information, if demanded by the user, can be combined with the original text in order to generate edited text.

6. An apparatus for executing a layer editing command in a pen computing system, the apparatus comprising:
-
a display screen for displaying at least original text to be edited;
a layer generating means for generating at least one transparent layer having a layer identifier in response to a layer editing command;
a recognition processor for translating trail information written on said display screen into computer-processible recognition data;

13. A method of executing an editing command in a pen computing system, the method comprising the steps of:
-
(a) entering a layer editing mode for editing original text displayed on a screen in response to a user'"'"'s demand. (b) generating a transparent layer having a layer identifier;
(c) sensing trail information generated by a pen input and corresponding positional information and displaying said trail and positional information on said transparent layer; and
(d) storing said sensed trail information and positional information according to said layer identifier. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
