First, the input process will be described with reference to FIG.
When the process starts, the stroke number n = 1 is set (S10
1), the handwriting input of the nth stroke of a character is performed using the tablet 102 (S102). This character is C _x
And It is assumed that the handwriting pen 103 used for handwriting input can detect whether or not the pen tip is in contact with the tablet 102 (S103). When the pen tip is in contact with the tablet 102, the coordinates of the pen tip are recorded as time-series information of the writing point of the nth stroke (S).
104). The measurement of the non-contact time is started when the pen tip is separated from the tablet 102 (S105 to 107).

The non-contact time r is compared with the set value R (S10
8) When the non-contact time r exceeds the set value R, the recognition process is started assuming that the handwriting input of all strokes of the character is completed. If the pen tip contacts the tablet 102 again before the non-contact time r exceeds the set value R, n + 1
Assuming that the handwriting input of the th stroke has started (S108, S106, S109), the input process is continued.

Next, the recognition process will be described with reference to FIG.
First, adjacent writing points of each recorded stroke are connected by a straight line to interpolate between the writing points (S201). Next, the polygonal line approximating each stroke is equally divided into k (k ≧ 1) polygonal lines, and 1, 2, ...
., K + 1 (1 is a stroke start point, k + 1 is a stroke end point) and numbers are assigned (S202). Next, a straight line connecting the division point i of the stroke n and the division point j of the stroke m, the division point i of the stroke n, and the division point j of the stroke m.
The angle Ω formed by the straight line connecting +1 is the {(k + 1) (n−
1) + i} row and (k + 1) N-row kN-column (N is the number of strokes) matrix P that is an element of the {k (m-1) + j} -th column is calculated (S203).

Next, M templates Q corresponding to characters having the same stroke number as the input handwritten character C _x.
The distance d _i (i = 1, ..., M) from _i (i = 1, ..., M)
, M) is calculated as the sum of squares of the elements of the matrix P-Q _i (S204). To select a character C _z corresponding to the template Q _z with the smallest distance d _z as a recognition result (S
205). The matrix P can be registered as it is as a template corresponding to the input handwritten character C _x (S206, 207).

The existing template Q _x corresponding to the character C _x can be corrected by replacing it with (P + Q _x ) / 2 (S208, S209). If there are other characters to be recognized, the process returns to step S101 and the above-described processing is repeated (S210).

Each point shown in FIG. 7A indicates a pen tip (writing point) recorded in the input process of FIG. As shown in FIG. 7 (B), these writing points are connected by straight lines next to each other, and line interpolation is performed between the writing points. Next, as shown in FIG. 7C, the polygonal line approximating each stroke is divided into four equal parts, and numbers 1, 2, 3, 4, 5 are given to the respective division points in accordance with the time series of the writing points. . Next, in this example, N = 2, k = 4, n = 1,
Since m = 2, the division point i of the stroke n (i = 1 to 1
5) and the straight line connecting the dividing point j of the stroke m (j = 1 to 4) and the straight line connecting the dividing point j of the stroke n and the dividing point j + 1 of the stroke m are the i-th row and the (4 + j) th row.
A 10-by-8 matrix P, which is the element of the column, is calculated. Figure 7
Since the angle Ω shown in (D) is i = 2 and j = 3, the matrix P
The elements of the second and seventh rows of are shown.

Further, instead of the above-mentioned writing point, a point in the velocity coordinate system of the writing speed at the writing point may be used. This is
In the step S104 of the input processing, the only difference is that the x-axis direction component v _x and the y-axis direction component v _y of the writing speed v at the writing point are obtained.

Each point shown in FIG. 8A indicates a point in the velocity coordinate system of the writing speed at the writing point recorded in the input process. The point at the origin of the velocity coordinate system is the point of the velocity coordinate system at the first writing point. The curve in which the speed of the last three writing points is positive is the stroke (n =
1) The velocity trajectory of the upper writing point, and thus the other curve is the velocity trajectory of the writing point on the right stroke (n = 2) of the letter "i". 8 (B), (C) and (D) are shown in FIG.
It corresponds to (B), (C), and (D), and a description thereof will be omitted.

Further, instead of the writing point, a point on the acceleration coordinate system of the writing acceleration at the writing point may be used. This differs only in that in step S104 of the input processing in FIG. 5, the x-axis direction component a _x and the y-axis direction component a _y of the writing acceleration a at the writing point are obtained.

FIG. 9 is an explanatory diagram of the points in the acceleration coordinate system of the acceleration at each writing point when the character “i” is input by handwriting, interpolation, stroke division, and matrix element Ω, as in the example of FIG. 7. Each point shown in FIG. 9A indicates a point in the acceleration coordinate system of the writing acceleration at the writing point recorded in the input processing. The point closer to the origin of the acceleration coordinate system is the point of the acceleration coordinate system at the first writing point. A curve in which the acceleration of all writing points is positive is a stroke (n
= 1) The acceleration trajectory of the upper writing point, and the stroke on the right side of the letter "i" (n =
2) It is the acceleration trajectory of the upper writing point. FIG. 9 (B),
7C and 7D are shown in FIGS. 7B, 7C and 7D, respectively.
, And their explanations are omitted.

As a method of detecting the writing speed and the writing acceleration, a method of providing a sensor (speed sensor, acceleration sensor) on the pen or a method of obtaining by calculation can be considered.

Next, the process of recognizing handwritten characters in a line-typed handwritten character in this embodiment will be described with reference to FIG.

First, the coordinates of the writing point of the input character having the number of strokes N measured using a tablet digitizer or the like are input (S301), and the coordinates of the writing point are interpolated by broken lines for each stroke (S302). , The interpolated polygonal line is equally divided into k sections (S303). The vector a and the matrix A are calculated using the coordinates of this division point (S304).

For example, when the character "i" is input by handwriting, the coordinates of the measured writing point (FIG. 7 (A)) are interpolated by broken lines as in the first embodiment (FIG. 7 (B)). , The polygonal line approximating each stroke is divided into four sections (Fig. 7).
(C)).

The matrix A is the division point i of the stroke n and the division point j of the stroke m, as in the embodiments of FIGS.
An angle Ω formed by a straight line connecting the dividing points i of the stroke n and the dividing point j + 1 of the stroke m (FIG. 7D)
{(K + 1) (n-1) + i} rows, {k (m-1) +
It is calculated as a matrix of (k + 1) N rows and kN columns, which is a component of the j} column.

Further, the vector a is, as shown in FIG. 13, the length L _{1 of} the first stroke, the distance L ₂ between the end point of the first stroke and the start point of the second stroke, ₂ , 2.
Th stroke length L ₃ each L ₁ + L ₂ + L divided by _{L 3 1 / (L 1 +} L 2 + L 3), L 2 / (L 1 + L 2 +
_{L 3), L 3 / (} L 1 + L 2 + L 3) and the element (2N-
1) Calculated as a dimensional vector.

After that, collation with each dictionary element is performed, and the character of the dictionary element having the smallest distance H by the matrix is output as the recognition result. Let M be the number of strokes when the characters of the dictionary element to be collated are written in a regular typeface. N and M are compared (S305), and when N ≦ M is not satisfied, the distance by the matrix between this dictionary element and the input character is H =
∞ (S306). When N ≦ M is satisfied, the distance G by the vector between this dictionary element and the input character is calculated (S307). Next, this distance G is compared with a preset threshold value (S308), and if it exceeds the threshold value, the matrix-based distance H between this dictionary element and the input character is set to H = ∞ (S306). If the threshold is not exceeded, the distance between the matrix A ′ composed of this dictionary element and the matrix A is calculated, and this is taken as the matrix distance H between this dictionary element and the input character (S3).
09). Steps S305 to S309 are repeated for all dictionary elements (S310), and the character for the minimum distance H among the distances H obtained by the matrix is output as a recognition result (S311).

As described above, the calculation of the distance G by the vector prior to the calculation of the distance H by the matrix is performed by determining the stroke order and the breaking method of the line typeface, and the distance G by the vector being less than a certain value. This is to reduce the amount of calculation of the distance H by calculating the distance H using only the matrix.

FIG. 11 is a flow chart showing the details of the calculation of the distance G by the vector of each dictionary element and the input character (S307).

First, the initial value of the distance G by the vector is G
= ∞ (S401). Each dictionary element has one or more stroke order information, and collation is performed for each stroke order. The minimum stroke number in the stroke order to be collated is set to M ′ (S40).
2). N and M ′ are compared (S403), and if N ≧ M ′ is not satisfied, the next stroke order is checked. When N ≧ M ′ is satisfied, MM ′ is determined from the connection position at MM ′ position.
Collation is performed for all combinations that select the connection positions of the locations (S404).

A combination Q of the stroke order and the connecting position to be collated
According to the above, the coordinates of the writing points of the character that the dictionary element has are distributed to N strokes and used as a template (S405), the coordinates of the strokes are interpolated by polygonal lines (S406), and the interpolated polygonal lines are equally divided (S407). Calculate vector a '(S
408). The absolute values of the differences between the respective components of the vector a and the vector a ′ are summed to obtain the distance g (S409). g and G are compared (S410), and if g <G, G = g is set, and the stroke order P and the combination position Q at this time are stored as Pmin and Qmin, respectively (S41).
1). It is determined whether there is a next combination of binding positions (S41
2) If there is, return to step S404 and repeat the above processing, and if not, go to step S413.

FIG. 12 is a flow chart of the calculation of H by the matrix (S309) which is performed when the distance G by the vector thus calculated does not exceed the preset threshold value.

First, the combination Q of the stroke order Pmin and the connecting position Q
The coordinates of the writing points of the characters that the dictionary element has are distributed to N strokes as a template according to min (S50).
1). The matrix A'is calculated for this template by the method described above (S502 to 504). Regarding the difference Ω _ij −Ω _ij ′ between the components of the matrix A and the matrix A ′, for example, 1-c
os (Ω _ij −Ω _ij ') is calculated, and the sum of all the components is taken as the matrix distance H (S505).

FIG. 14 is a diagram showing the character “right” input by handwriting as a 4-stroke (N = 4) character, and FIG.
FIG. 17 is a diagram showing dictionary elements matched with this, and FIGS. 16A to 16D are diagrams showing templates. In the dictionary, “right” is registered as a 5-stroke character (M = 5), and the brush point coordinates 12345 and 2 shown by black circles in FIG.
The combination of the two strokes 1345 and the minimum stroke number for each stroke is 3 (M '= 3), and the stroke and the stroke immediately before the stroke can be continuously written at two locations shown by the broken line in FIG. It has position information as stroke order information.

In the calculation of the distance G by the vector (FIG. 11), two combinations of stroke order and MM ′ = 1 combination position are selected from MM ′ = 2 connection positions. , A vector a ′ is calculated for the four templates of FIGS. 16A, 16B, 16C, and 16D, and the distance G is calculated by the vector.

Although the present invention has been specifically described based on the above embodiments, the present invention is not limited to the above embodiments and various modifications can be made without departing from the scope of the invention. Is.
