Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inking function for performing drawing processing for drawing pixels forming a line connecting an input coordinate point sequence, or for storing a file or reading a stored file. The present invention relates to an information processing apparatus that provides an extended function for improving operability of a user with respect to a file processing function to be performed.

[0002]

2. Description of the Related Art Some conventional information processing apparatuses generally provide the same functions as word processors. The word processing function includes a file processing function of storing a file and reading the stored file.

Further, in such an information processing apparatus, it is possible to perform handwriting input using a pen, a finger, a mouse or the like, that is, to directly input coordinate points (hereinafter referred to as "stroke data"). Some also provide a handwriting input function that is possible. The handwriting input function includes an inking function of drawing pixels (hereinafter, referred to as "inking") that form a line connecting stroke data.

[0004]

In the information processing apparatus that provides the handwriting input function, there is a problem in operability for the user during handwriting input as described below.

For example, when a user uses a pen to perform handwriting input, there is a characteristic that the user is likely to bend at the start and end of the input because the speed becomes slow or force is applied.

Further, because of such difficulty in writing, the user has to make handwriting input as large as possible, so that the amount of information that can be written in the displayable range becomes small.

When writing small, the written locus may be obscured and cannot be seen. Therefore, in order not to do so, handwriting input should be performed after inputting an instruction to change the line width in advance. You have to do it.

Further, when the user uses the pen to perform handwriting input, depending on the material of the pen tip, it becomes slippery and it becomes difficult to write a straight line. Incidentally, this problem has been solved by the technique described in JP-A-60-49483. That is, this technique draws a perpendicular line from all stroke data between the start point and the end point with respect to a straight line connecting the start point and the end point of the input stroke data, and the lengths of all the perpendicular lines are predetermined. If the length is smaller than the predetermined length, the stroke data between the start point and the end point is regarded as a straight line, and the start point and the end point are connected by a straight line.

On the other hand, an information processing apparatus that provides a word processor function, regardless of whether or not it provides a handwriting input function, has a problem in terms of user operability as described below.

For example, when storing a file, the file is given a file name and stored. At this time,
Furthermore, it is conceivable to add a keyword for a search so that it can be easily classified as a file that has already been stored. In this case, it is necessary to give the same keyword to files that are to belong to the same classification, but for this purpose, the user must remember the keyword given to the already stored file. I need to put it. That is, if the keyword is not remembered, it becomes necessary to sequentially display and confirm the keywords assigned to the already-stored files, or to re-assign the keywords later.

If a user finds a file that is no longer useful and does not find and delete such file, the storage capacity for storing the file will only increase.

An object of the present invention is to improve user operability with respect to an inking function for inking stroke data or a file processing function for storing a file or reading a stored file. It is to provide the extended function of and improve the usability of the user.

[0022]

For example, in the information processing apparatus as described in (1), when the user inputs by handwriting using the pen,
Even if you bend at the beginning or end of input due to slowing down or applying force, inking should be performed on the part of the handwritten input stroke data excluding the vicinity of the start and end points. Therefore, the bent portion can be corrected.

Further, for example, in the information processing device as described in (2), even if handwriting input is performed so as to overlap an already existing pixel, the stroke data input by handwriting among the already existing pixels Since the color of the pixel in the portion which is in contact with the line in which the inked pixels are sequentially connected is changed, the color can be made easier to see.

Further, for example, in the information processing apparatus as described in (3), for each stroke data input by handwriting, two lines connecting the stroke data and two adjacent stroke data are formed. When the angle is larger than the predetermined angle, the inking is performed so that the width of one of the two lines forming the angle is different from the standard width. If the stroke data is in particular a character, it becomes possible to thicken the vertical line of the character like a so-called Mincho typeface, and the display can be made easy for the user to read.

Further, for example, in the information processing device as described in (4), when the density of the inking pixel in the rectangle circumscribing the figure composed of the pixel is larger than the predetermined density. , The stroke data corresponding to the pixel is inked again so that the width of the line connecting them is different from the standard width. Therefore, if the density is increased, the width is reduced so that the user can Even if you write by handwriting small, the locus of writing will not be crushed and disappear.

Further, for example, in the information processing apparatus as described in (5), even when the stroke data handwritten by the user is small and the pixel in which the stroke data is inked is crushed and cannot be seen, By the user's instruction, the width of the line corresponding to the pixel can be reduced.

Further, for example, in the information processing apparatus as described in (6), the stroke data manually input by the user is large, and there is no place for continuous handwriting input due to the pixel in which the stroke data is inked. Even if the user instructs after inputting,
Since it becomes possible to reduce the size of the figure composed of the pixels, it is possible to secure a place for input.

In addition, for example, in the information processing apparatus as described in (7), when storing a file, a list of keywords assigned to the already stored file is displayed. Therefore, the user can input the keyword to be added while looking at the displayed list of keywords.

Further, for example, in the information processing apparatus as described in (8), when the file already stored is read and then the file is stored again, the keyword assigned to the file is re-stored. Since they are added, the user does not have to enter the keyword to be added again.

Further, for example, in the information processing apparatus as described in (9), when the file name of another file is given as the keyword of the read file, the user is notified to that effect. Therefore, if the user gives the file name of the related file as a keyword of a certain file, the user can refer to the displayed contents when reading the file and It turns out that there exists.

Further, for example, in the information processing apparatus as described in (10), when there is a file in which a keyword matching the selection-instructed keyword among the keyword files is stored in association with the file, the file is stored. The file name and part of the file are displayed, and the number of files is displayed.
The user can refer to the already stored file only by remembering the file name of the keyword file.

Further, for example, in the information processing apparatus as described in (11), all the files in which the keywords matching the selection-instructed keyword among the keyword files are associated and stored are one file. Since it is designed to be stored in
When adopting a work mode in which one user collaborates to create a file, each user simply assigns the same keyword to the file created by himself / herself, and the file created by each user later is created. The operation when combining them into one file becomes easy.

Further, for example, in the information processing device as described in (12), when there is a file associated with a read number smaller than a predetermined number of times,
Since the file name of the file, a part of the file, and the number of the file are displayed, the user forgets to store the file,
Even if there is a file that is not effectively used, the user can know the existence of the file that is not effectively used by referring to the displayed contents.

In addition, for example, in the information processing apparatus as described in (13), when there is a file whose period from the associated storage date and time to the present is longer than a predetermined period, the file is The file name and part of the file are displayed, and the number of the file is displayed, so the user forgets that the file has been memorized, and there is a file that has not been read recently. Even if there is, the user can know the existence of a file that has not been read recently by referring to the displayed contents.

As described above, according to the present invention, the operability of the user for the inking function for inking the stroke data or the file processing function for storing the file or reading the stored file. Since the extended function for improving the user interface is provided, the usability for the user can be improved.
