Next, as shown in FIG. 2A, m is divided by vertical and horizontal ruled lines on the display screen 2a of the electronic whiteboard 2 in the electronic whiteboard system shown in FIG.
Xn character entry frames 10 are displayed, and characters A, B, and C have already been entered in some of these character entry frames as shown in FIG. Referring to FIGS. 2 and 3, a description will be given of a display content control method according to the present embodiment with respect to an operation of writing a character "X" with the pen 1 so as to overlap a ruled line between character entry frames as shown in e). I do.

[0036] As shown in FIG.
When the character "X" is written between 0, that is, the vertical ruled line, a new frame 11 is set between these adjacent left and right frames as shown in FIG. The above character "X" is displayed in the frame 11 and the subsequent characters are sequentially shifted rightward. As shown in FIG. 2E, when the character “X” is written between the vertically adjacent frames 10,
As shown in FIG. 11F, a new frame column 12 for forming an inserted line is set between these adjacent upper and lower frames, and the written “X” is written among the frames forming the newly provided frame column. Is displayed in a frame immediately below the character string, and the character string below is sequentially shifted downward. When the character “X” is written so as not to overlap the ruled line, the character
It is the same as before.

FIG. 3 shows a control program executed by the display content processing section 43 of FIG. 1 at the time of the above-described character / line insertion processing. This program is displayed when the character entry frame 10 shown in FIG. It is assumed that the processing is started in step 71 when a character is written with the pen 1 in the area where the pen is. First, in step 72, the upper left of FIG.
Using the coordinate data (Left, Top) shown in (c) and the width Width and height Height shown in FIG. 2A of the character entry frame 10, the integer part of Left / Width is substituted for X, and Top /
Substitute the integer part of Height into Y.

In step 73, it is determined whether or not the written character "X" overlaps the (X + 1) th vertical ruled line as shown in FIG. 2C.
As shown in FIG. 4D, the number of m from the (X + 1) column in the Y row is m.
The column, that is, the characters on the right side of the (X + 1) th ruled line are sequentially shifted to the right, and in step 75, (X + 1,
The character "X" is written and displayed in the empty frame 11 in Y).

If it is determined in step 73 that the character "X" does not overlap the (X + 1) -th vertical ruled line, then in step 76, the written character "X" is replaced with the character "X" in FIG.
It is determined whether or not it overlaps the (Y + 1) th horizontal ruled line as shown in FIG. If they overlap, in step 77, n rows from (Y + 1) row, ie, (Y +
1) Rows below the first ruled line are sequentially shifted down by one row to set an empty frame column 12 in the (Y + 1) th row. The character "X" is written and displayed in the (X, Y + 1) frame immediately below the character "X".

When it is determined in steps 73 and 76 that the character "X" does not overlap the vertical ruled line or the horizontal ruled line, in step 79, (X, Y) at the position where the character "X" is written ) Is written in the frame 10 and displayed.

Therefore, the display content control method according to the present embodiment can be applied to a case where a character is written between adjacent frames on the left and right when inputting the character. You can enter characters in the same way as inserting a character, and you can re-enter the next character from here or add a new character display frame manually to enter characters. It is not necessary to correct the pen input, and it is possible to exhibit good pen input, and it is possible to avoid occurrence of a situation where the operator feels troublesome rather than pen input.

Also, when a character is written between adjacent vertically adjacent frames when inputting the character, the character is written in the same manner as a manual operation of directly inserting a character between lines as performed on paper. And no need to re-enter the next character from here, or manually add a new character display frame row and re-enter characters, demonstrating the goodness of pen input. In addition, it is possible to avoid a situation in which the operator feels troublesome on pen input.

Next, on the display screen 2a of the electronic whiteboard 2 in the electronic whiteboard system shown in FIG. 1, a check box 13 relating to each of the items 1 to n is vertically set by the projector 3 as shown in FIG. The check groups 14 that are continuously present are displayed, and the display content control method according to the present embodiment will now be described with respect to the operation when checking consecutive items 1 to 4 as shown in FIG. This will be described with reference to FIGS.

In this case, the operator wants to check (ON) the pen 1 as shown in FIG.
4) Touch the display screen 2a at the top item (item 1). Next, in this contact state, the pen 1 is moved downward so as to cross the item (items 1 to 4) to be checked (ON) as shown in FIG.
N) The pen 1 is moved to the right when reaching the lowest item (item 4) of the items (items 1 to 4) to be operated, and then the pen 1 is released from the display screen 2a. At this time, FIG.
As shown in (1), it is assumed that the check boxes of the continuous desired items 1 to 4 are collectively turned on. Note that pen 1
When the item is moved to the left and away from the display screen 2a after reaching the bottom item (item 4), the items 1 to 4 are unchecked and turned off.

FIGS. 5 and 6 show a control program executed by the display content processing unit 43 shown in FIG. 1 when the check box 13 is turned on and off. This program displays the check group 14 shown in FIG. It is assumed that the processing is started in step 81 when the pen 1 is pressed in the area where the pen 1 is pressed. First, in step 82 of FIG. 5, the pen coordinates (X,
Y) is substituted for startX, which is the X coordinate of the call start point shown in FIG.
Assign to yBottom respectively.

In the next step 83, it is determined whether or not the pen 1 has been moved. While the pen 1 is being moved, in step 84, the Y of the current pen coordinates (X, Y) is set to yT.
When it is determined that the value is smaller than the value of op, y is substituted for yTop in step 85 and updated, and in step 86 the current pen coordinates (X,
Y) When it is determined that Y exceeds yBottom, yBottom is updated by substituting Y for yBottom in step 87, and it is determined in step 84 that the Y of the current pen coordinate is greater than or equal to yTop, and 86 is the current pen coordinate Y is yBotto
When it is determined that it is less than m, steps 85 and 87 are not executed, and yTop and yBottom are not updated.

After the updating of yTop and yBottom, the control proceeds to step 88, where the locus 15 of the pen 1 is displayed as shown in FIG. Recognize Here, as is clear from the above, yTop and yBottom are each shown in FIG.
As shown in (c), the Y coordinate at the uppermost point and the Y coordinate at the lowermost point of the locus 15 of the pen 1 are represented. In the next step 89, it is determined whether or not the pen 1 has been released from the display screen.
Is repeated, and the Y coordinate yTop at the top point of the pen locus 15 and the Y coordinate yBottom at the bottom point are continuously updated.

When it is determined in step 89 that the pen 1 has been released from the display screen, the control proceeds to step 90 in FIG. 6, and in step 90, the X of the current pen coordinates (X, Y) is changed to the X of the call start point. It is determined whether or not the pen 1 has been moved to the right based on whether or not the value obtained by adding 10 to the coordinate startX has been exceeded. At the time of this right movement, iCheck is set to 1 in step 91 to indicate this. In step 92, the X of the current pen coordinates (X, Y) is the X coordinate of the call start point.
It is determined whether the pen 1 has been moved to the left based on whether it is smaller than the value obtained by subtracting 10 from startX.
When it is set to 1 and it is determined that the pen 1 has not been moved in the left and right directions in steps 90 and 92, iCheck is reset to 0 in step 94 to indicate this.

Next, the control proceeds to steps 95 to 102, in which the check items between the uppermost point Y coordinate yTop and the lowermost point Y coordinate yBottom of the pen locus 15 are determined, that is, from where to how far the pen 1 is. It is determined whether or not the check items that have been crossed have been crossed, and whether the crossed check items should be turned ON or OFF. Therefore, first in step 95, a switch (Switch) given for each check item as shown in FIG.
Is reset to 0, and the pixel number yPixel in the Y coordinate direction is reset to 0.

In the next step 96, each check item Sw
Switch the height of itch (i) as shown in Fig. 4 (a).
(I). When Height is set, yPixel + Switch (i). Heig
It is determined whether or not ht is greater than or equal to the uppermost point Y coordinate yTop of the pen locus 15 and yPixel is less than or equal to the lowermost point Y coordinate yBottom of the pen locus 15.
If it is determined that iCheck is 1 in Step 98, Switch
(I) is set to True, the corresponding check item is turned ON,
If it is determined in step 99 that iCheck is -1, Switch (i) is set to False in step 100, and the corresponding check item is turned off.
If it is determined that the above condition is satisfied, steps 98 and 100 are skipped, and Switch (i) is held as it is.

In the next step 101, yPixel is changed to [yPix
el + Switch (i). Height], and the counter i of the switch is incremented. While it is determined in step 102 that the counter i of the switch is less than the number n of check items, step 9
By repeating the above loop including 6 to 101,
All the check items crossed by the pen 1 are switched on or off at once, or are maintained as they are. When it is determined in step 102 that the counter i of the switch has reached the number n of check items, in step 103, the pen locus 15 shown in FIG.
Is erased as shown in FIG. 11D, and the batch ON / OFF switching of the selected check items is completed.

In the display content control method according to the present embodiment, when checking or unchecking desired continuous check items among check boxes in which check items are continuous in the vertical direction of the display screen. By simply passing the pen 1 in a contact state in the vertical direction on the display screen so as to pass through the desired continuous check items, the desired continuous check items can be selected. By simply moving the pen 1 on the display screen in one of the left and right directions (the right direction in the above example), these selection items can be checked all at once. The check of these selection items can be removed collectively when shifting to.

Therefore, in the display content control method according to the present embodiment, when items to be checked or unchecked are continuous, each check box is individually turned on / off.
A plurality of check items can be turned ON / OFF collectively without switching to a state, and a check operation on a check box can be efficiently performed.

Next, as shown in FIGS. 7A to 7C, selectable radio buttons 16 for each of the items 1 to 4 are displayed on the display screen 2a of the electronic whiteboard 2 in the electronic whiteboard system shown in FIG. A radio button group 17 that is present continuously in the vertical direction of the display screen is displayed. From now on, the radio button of item 1 is selected and turned on as shown in FIG.

First, as shown in FIG. 9A, the operator brings the pen 1 into contact with an arbitrary item (item A in the drawing) in the scroll area 19, and here, the pen 1 touches the upper side of the scroll area 19 while keeping the pen 1 in contact. When the pen 1 is moved upward, the entire items in the scroll area 19 can be scrolled downward.
It is assumed that the entire item in 9 can be scrolled upward. The target item can be displayed in the scroll area 19 and selected by such scrolling as usual, but in the present embodiment, the target item can be further selected as follows.

That is, as shown in FIG. 9A, the pen 1 is brought into contact with an arbitrary item (item A in the drawing) in the scroll area 19 to select it, and then the pen 1 is kept in the contact state as shown in FIG. As shown by α in b), the scroll area 19 is moved out of the left and right sides. At this time, the menu item 18 in the scroll area 19 is changed as shown in FIG.
Preferably, the display is reduced so that all the items are displayed, and the items immediately adjacent to the pen 1 are displayed outside the scroll area 19 in contact with the left and right sides thereof.

Next, when the pen 1 is moved up and down as indicated by β in FIG. 9C while keeping the pen 1 in contact with the outside of the scroll area 19, the selection items 18a displayed outside the scroll area 19 are also changed. The item is changed to the item beside, and the target item G can be selected. When the selection item 18a becomes the target menu item G, the pen 1 is moved left and right into the scroll area 19 as shown by δ in FIG.
It is assumed that the items in the scroll area 19 are enlarged and displayed at the original magnification while the icon is selected.

FIG. 10 shows a control program executed by the display content processing section 43 of FIG. 1 when selecting the above menu. This program is executed when the pen 1 is pressed in the scroll area 19 of the menu item 18 shown in FIG. It is assumed that the processing is started in step 121 when the time has elapsed.

It is determined whether or not the pen 1 has passed the upper side of the scroll area 19, and when it has exceeded, the scroll area 1 is determined in step 123.
Scroll the entire item in 9 downward. In step 124, it is determined whether or not the pen 1 has passed the lower side of the scroll area 19, and if so, in step 125, all the items in the scroll area 19 are scrolled upward. However, when it is determined in Steps 122 and 124 that the pen 1 does not exceed any of the upper and lower sides of the scroll area 19, Steps 123 and 125 are not executed, and thus the scrolling is not performed. .

After the scroll control, step 12 is executed.
6, an item corresponding to the coordinates of the pen 1 is selected. Then, in step 127, it is determined whether or not the X coordinate of the pen 1 is out of the range of the scroll area 19, that is, the pen 1
It is determined whether the scroll region 19 has moved out of the left and right sides as exemplified by α in FIG. If the pen 1 goes out of the left and right sides of the scroll area 19, step 128
, The size of the item display font is reduced so that all items are displayed in the scroll area 19. However, when the item display font becomes smaller than 2 points, it becomes difficult to confirm the item. Therefore, the size of the item display font is limited to at least 2 points.

In step 129, the pen 1 is
It is determined whether or not it has returned to the inside of the scroll area 19 as indicated by δ in (d). If it has returned, in step 130, the size of the item display font is set to a default value.
The item display is returned to the original magnification and enlarged. Step 1
At 31, the same determination as in step 127 is performed. If the pen 1 is out of the left and right sides of the scroll area 19 as shown in FIGS. 9B and 9C, step 1 is performed.
At 32, the item selected in step 126 is enlarged and displayed in contact with the left and right sides of the scroll area 19.

In step 133, it is determined whether or not the pen 1 has been released from the display screen. Control is returned to step 122 until the pen 1 is released, and the above control is repeated. The control ends.

According to the display content control method according to the present embodiment, when one of the vertically continuous menus displayed on the display screen is selected by the pen 1, the pen 1 moves the menu scroll area 19. When the pen 1 is moved in the horizontal direction, the menu in the scroll area 19 is displayed in a reduced size so that all items are displayed as much as possible. When one of the menus in the scroll area is selected and the pen 1 is returned to the scroll area 19 after the selection, the menu display in the scroll area is returned to the original magnification, so that when the menu is selected, the menu is scrolled up and down. Or scroll the menu up or down until the desired menu item appears on the screen. It is possible to reduce the amount of scrolling, without or overshoot even scrolling when the number of menu items is large, easy selection of menu items, and a short time, yet can be reliably performed.
