Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an input / output integrated information processing apparatus represented by a pen input computer.

[0002]

2. Description of the Related Art Conventionally, in an input / output integrated information processing apparatus, it is general to write characters as if they were written on paper by directly writing characters on an input surface of a digitizer or the like instead of a keyboard.

FIG. 2 is an explanatory view of a display example of a character frame and a method of inputting a character into the frame. As shown in FIG.
When inputting 1, display a square frame 202 on the display,
The character 201 is input into the frame as if writing on paper. The character 201 is generally converted into a character code by a character recognition device incorporated in the integrated information processing device and stored in the integrated information processing device. Character 2 in FIG.
03 is a recognition result.

[0004]

However, in the above-mentioned conventional example, the character input frame is displayed at the time of character input, and the handwriting displayed when inputting with a pen in the character frame has the following drawbacks. It was

FIG. 3 is an explanatory view of a display example of a character input frame and a method of inputting characters into the frame. As shown in FIG. 3, the character input frame 301 is displayed, and only one type of line thickness (usually 1
It is the display of handwriting in dots. Characters 302 and 303 are echo back of handwriting with a pen, and character 304 is a recognition result. That is, the echo back of the handwriting always has the same line thickness regardless of the size of the character input frame 301.
For this reason, despite the large character input frame, there is a drawback in that the thickness of the echo back line of the handwriting is too thin and there is a very strange feeling when inputting.

As a means for compensating for this drawback, it has been considered that the thickness of the line of pen handwriting can be selected. However, this method cannot be said to be a comfortable user interface because an operation procedure for selecting the thickness of the line of the handwriting is required, and it is not a good user interface because there is only one type of pen thickness.

Regarding the change of the size of the character input frame, the recognition method of the character recognition software, the resolution of the digitizer, the complexity of the written character such as the number of strokes, the size of the display, the resolution, and other display It is difficult to select a certain optimum size due to the overlap of the character input frame and the character input frame, and at present, it is general to always make the character input frame of a certain size, but due to the above factors, It is desired to display the size of the character input frame so that the size of the character input frame can be freely changed depending on the situation of character input. The size of the character input frame may be changed automatically, but it is also conceivable that the operator sets the size of the character input frame according to a numerical value set by the operator.

It is an object of the present invention to provide an input / output integrated information processing apparatus capable of determining the thickness of a pen handwriting line according to the size of a character input frame.

[0009]

In order to achieve the above object, an input / output integrated information processing apparatus according to claim 1 is an input / output integrated information processing apparatus equipped with a transparent coordinate input device. A character frame size storing means for storing the size of the frame, an echo back means for echoing back the input coordinates as handwriting to the display device, and a line width determining means for determining the echo back line width from the size of the input character frame. It is characterized by

[0010]

According to the input / output integrated information processing apparatus of claim 1, since the line thickness of the handwriting of the pen is determined according to the size of the character input frame, the pen according to the size of the character input frame is determined. The echo back of the handwriting can be displayed, the operator's feeling of use can be made natural, and the user interface can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the input / output integrated information processing apparatus of the present invention will be described in detail below with reference to FIG. here,
FIG. 1 is a block diagram showing the configuration of a first embodiment of an input / output integrated information processing apparatus of the present invention.

In FIG. 1, reference numeral 1 is a coordinate input device represented by a transparent digitizer composed of, for example, a pressure sensitive sheet. The coordinate input device 1 may be a system other than the pressure-sensitive digitizer as long as it is transparent. Reference numeral 2 is a display device represented by a liquid crystal display. The coordinate input device 1 and the display 2 are
It is structurally integrated and is configured as a so-called pen computer. The echo back means 3 displays an echo on the display device 2 as a pen handwriting on the display device 2 based on the coordinate value input from the coordinate input device 1.

The character box size storage means 5 stores the size of the input character box determined by the input character box display means (not shown). The input character frame display may be performed by an application or a character recognition program. The character input size storage means 5 may be composed of the RAM of a normal computer system.

The line width determining means 4 is a character box size storing means 5
The character box size is read, and the echo back means 3 is notified of the value corresponding to the character box size. The echo back means 3 notifies the display device 2 of the echo back of the pen handwriting based on the notified line width.

The operator inputs with a pen 6 into a transparent pressure-sensitive digitizer like a normal pen. The pen tip of the pen 6 is usually made of resin or the like.

The line width determining method of the line width determining means in this embodiment will be described below with reference to FIG. FIG. 4 shows a first input / output information processing apparatus according to the present invention.
3 is a flowchart of a line width determination method of the line width determination means in the embodiment of FIG.

First, in step S41, the value stored in the character box size storage means 5 which is, for example, a RAM is read out by accessing it like a normal program variable to know the character box size. This character frame is a square. Next, in step S42, for example, from the conversion table of the character box value vs. line width type configured as shown in FIG.
The line width type is determined based on the character frame size obtained in step 41. In FIG. 5, for example, the size of the character frame is 16
If so, the line width type value is set to 2 from the conversion table. Here, FIG. 8 shows an example of a display format by the line width type in FIG. For example, if the line width type is 2,
The line width type 2 of FIG. 8 is used. Therefore, when the character box size is 16, the echo back is displayed with a width of 2 dots in the horizontal direction. In FIG. 5, the value of the character box size 999 represents the maximum value. The device of this embodiment includes
A unit for changing the character frame value and the line width size in the conversion table of FIG. 5 is provided, which improves the user interface property.

Further, in step S43, step S4
The line width type obtained in 2 is notified to the echo back means 3.

The echo back method of the echo back means in this embodiment will be described below with reference to FIG. FIG. 6 is a flow chart of the echo back system of the echo back means in the first embodiment of the input / output integrated information processing apparatus of the present invention.

First, in step S61, the coordinates input from the coordinate input device (digitizer) 1 are read. The coordinates to be read are the coordinates of two-dimensional data of X 1 and Y 2 as shown in FIG. 7, and this is general. Next, in step S62, the read coordinates are converted for the display device 2. The coordinate conversion is necessary because the resolution of the coordinate input device 1 and the resolution of the display 2 are generally different. Usually, the coordinate conversion input device has a higher resolution. In the input / output integrated information processing apparatus, the input position with the pen and the echo back to the display, which is the handwriting, must match, so the above-mentioned coordinate conversion is important.

This transformation is obtained by dividing the input coordinates of X and Y by a fixed number. In step S63, the line width determined by the line width determining means 4 is obtained. Next step S6
In step 4, the line width obtained in step S63 is used in step S62.
Display the coordinates on the display converted by. FIG. 8 shows the display shape of the line width when displayed in step S64. FIG.
5 is an explanatory diagram of an example of a display format according to various line width types in FIG. 5. For example, in the case of a character frame size 16, the line width type is 2 from FIG. 5, and the line width type of FIG. 8 is 2.
If this type is used, the echo back is displayed with a width of 2 dots in the horizontal direction.

(Second Embodiment) The character input frame stored in the character frame size storage means 5 in the first embodiment is a square, and the stored value is one-dimensional. However, the character input frame may be rectangular. This is because there are cases where the size of the display device is limited, and there are cases where the character input frame is displayed as much as possible on one line. In that case, 2
The line width of the echo back may be determined by the dimension, that is, the size of the vertical (Y) and horizontal (X) values of the character frame, or the average of these may be used to determine the line width. However, instead of the one-to-one correspondence table shown in FIG. 5, the determined character frame size and X, as shown in the table in which the line width types of FIG. A correspondence table of 1 to 3 is set according to the size of Y.

In the example of FIG. 9, when the character box size is 20, for example, if the character input box is vertically long (X <Y), the value "6" is set as the line width. When the handwriting is displayed as an echo by the echo back means, the line width has a one-to-one correspondence with the character frame size in FIG. 8, but as shown in FIG. 10, the same line has a long line width in the X direction. Alternatively, a line width long in the Y direction is treated in the same manner as the relationship between X and Y in the character input frame. For example, when echoing back a line width of 2 dots, 104 in FIG. 10 is used when the character frame is vertically long, and 1 in FIG. 10 is used when the character frame is horizontally long.
02 is used, and when the character frame is a square, 103 in FIG. 10 is used. Further, in the case of "6" in FIG. 9, the line width of 2 dots is used, and 104 in FIG. 10 is used as the line width shape of the line width 2 to perform echo back.

According to the structure of this embodiment as well, the echo has a line width corresponding to a rectangular character frame, and the human interface can be improved.

In the first and second embodiments described above, the input / output integrated information processing apparatus represented by a pen computer has been described, but this embodiment is large-sized represented by an electronic blackboard, for example. More effective by the device of.

In addition, each of the configurations described in the first and second embodiments does not require any hardware other than the hardware required to configure the input / output integrated information processing apparatus, and does not require software. It can be easily configured by adding.

Further, in the first and second embodiments,
As shown in FIG. 11, a general computer system and peripheral devices can be used, and in particular, an integrated pen computer can be used. As for each means, the storage means is a normal RAM, and the other means can be realized by a simple and easy configuration, as already shown, so that it is economical.

[0028]

According to the input / output integrated information processing apparatus of claim 1, since the line thickness of the pen handwriting is determined according to the size of the character input frame, the size of the character input frame is determined. An echo back of the pen's handwriting may be displayed, giving the operator a natural feel and improving the user interface.
