ABSTRACT:
DETAILED DESCRIPTION OF THE INVENTION
1. Field of the Invention
The present invention relates to a handwriting input display method suitable for, e.g., an electronic notebook apparatus and a portable computer.
2. Description of the Prior Art
Very recently, a CAD system has grown, and then an arbitrary pattern, or figure may be relatively simply inputted. In this CAD system, when a pattern having an arbitrary shape is drawn by using, for example, a mouse and a pen, a pattern corresponding to this input pattern is displayed on a monitor. Then, for example, after a plurality of line segments have been entered, the preselected parameters are designated in order to change the display conditions of these line segments.
For instance, when a plurality of line segments elongated along the vertical direction are displayed in such a manner that the upper ends thereof are aligned along the horizontal direction, the below-mentioned parameters are entered:
(1). A designation is made of a line segment of interest.
(2). A designation is made of reference points for the respective line segments of interest.
(3). A straight line such that the reference points for the respective line segments of interest should be aligned is entered.
(4). A designation is made as to whether or not an interval between the reference points is adjusted.
(5). A designation is made of the positions of the reference points at both ends after alignment.
(6). A designation is made of a method for transporting a line segment of interest (for example, a designation is made as to whether the line segment is transported along the y-axis direction, or along the direction of the line segment).
Otherwise, a predetermined mode is selected by way of the menu operation, and the process operations for the respective line segments are wholly designated.
However, the above-described parameter designating method owns such problems that the lengthy operating procedure is required and lengthy process time is needed. There is another problem that since the parameter designation is carried out by entering the numeral values, this parameter designation cannot be intuitively performed, resulting in poor operability.
Furthermore, the menu operation method owns the following drawbacks:
(1). It is difficult to designate an arbitrary point and an arbitrary direction at high speed.
(2). It is difficult to simply utilize the featured amounts of the established line segments (for example, an arbitrary point on a line segment of interest, a direction, or a length of a line segment of interest).
(3). When the numeral value is entered to designate the featured amount, it is difficult to intuitively input the featured amount.
The present invention has been made to solve these problems, and therefore has an object to provide such a method for performing an input process of a shape more quickly and more simply.
A handwriting input display method as described in claim
1
is characterized in that a plurality of line segments are displayed, a gesture is inputted so as to establish a predetermined relationship with said line segments; and display conditions of said lien segments are changed in response to said gesture.
A handwriting input display method as described in claim
2
is characterized in that a plurality of shapes are displayed; a gesture is inputted so as to establish a predetermined relationship with said shapes; a featured amount of said gesture is detected; and display conditions of said shapes are changed in accordance with the featured amount of said gesture.
This gesture may contain a handwritten character. Also, characters may be aligned by this entered gesture.
In accordance with the handwriting input display method as recited in claim
1
, when the gesture is inputted to establish a predetermined relationship with the line segment, the display conditions of the line segment are changed in such a manner that the interval between the line segments is aligned in response to this input gesture. As a result, the display condition of the line segment can be simply and quickly changed.
In accordance with the handwriting input display method as recited in claim
2
, when the gesture is inputted to establish a predetermined relationship with the shape such as the character and the pattern, for instance, the shapes are aligned with an equidistant interval at the input position of this gesture in response to the featured amount of this gesture. As a result, it is possible to easily and quickly change the display condition of the shape.
