Apparatus and method for inputting writing information according to writing pattern
First Claim
1. A handwriting inputting apparatus comprising:
- a position measuring unit which measures a position of an object by which a user inputs handwriting to generate coordinate information;
a pattern DB which stores handwriting pressure pattern information which is defined in advance;
a pressure information generating unit which generates virtual handwriting pressure corresponding to the coordinate information according to the handwriting pressure pattern information selected by the user by using the coordinate information; and
an input unit which receives the handwriting pattern used for generating handwriting information selected by the user and outputs the selected handwriting pattern to the pressure information generating unit;
wherein the plurality of handwriting pressure patterns include a 1st pattern which is represented so as to generate a high handwriting pressure with respect to one of horizontal and vertical strokes and to generate a low handwriting pressure with respect to the other thereof, a 3rd pattern which is represented so as to generate a pressure value by allocating different weighting factors according to increasing and decreasing directions of an X or Y coordinate value of the coordinate information, and a 4th pattern which is represented so that a high pressure is set to a starting portion of a handwriting stroke, and as the handwriting proceeds, the pressure is gradually decreased, or wherein the pattern information is represented so that a low pressure is set to the starting portion of the handwriting stroke, and as the handwriting proceeds, the pressure is gradually increased.

Abstract
Provided are a method and apparatus for inputting handwriting in a digital electronic apparatus. Various patterns defining methods of generating pressure information according to handwriting input are stored in advance, and a user selects a pattern similar to a pattern of the user or selects a desired handwriting pattern to perform the handwriting, so that pressure information is generated according to the handwriting pattern and the handwriting is displaying with a thickness corresponding to the pressure information. Therefore, it is possible to solve a problem of monotonous handwriting input in the related art where only the position is input and the handwriting is output with the same thickness.

9. A handwriting inputting method of inputting handwriting in a handwriting inputting apparatus, comprising steps of:
-
(a) allowing a user to select a handwriting pressure pattern among a plurality of handwriting pressure patterns stored in a pattern database; (b) measuring a position of an object by which the user inputs the handwriting to generate coordinate information; and (c) reading handwriting pressure pattern information selected by the user from the pattern database and generating virtual handwriting pressure information corresponding to the coordinate information according to the handwriting pressure pattern information by using the coordinate information; wherein the plurality of handwriting pressure patterns include a 1st pattern which is represented so as to generate a high handwriting pressure with respect to one of horizontal and vertical strokes and to generate a low handwriting pressure with respect to the other thereof, a 3rd pattern which is represented so as to generate a pressure value by allocating different weighting factors according to increasing and decreasing directions of an X or Y coordinate value of the coordinate information, and a 4th pattern which is represented so that a high pressure is set to a starting portion of a handwriting stroke, and as the handwriting proceeds, the pressure is gradually decreased, or wherein the pattern information is represented so that a low pressure is set to the starting portion of the handwriting stroke, and as the handwriting proceeds, the pressure is gradually increased. - View Dependent Claims (10, 11, 12, 13, 14, 15)
