The number of persons and their seating positions are sent to the CPU 111. CPU1
Reference numeral 11 divides the display 107 into a common area and a personal area based on the number of attended conference attendees and the seating position.

The process of dividing the area of the display surface of the display 107 will be described in detail with reference to FIGS. FIG. 12 is a diagram illustrating a state where a table conference is being performed using the above-described electronic information display device, and FIGS. 13 and 14 are diagrams illustrating a method of area division. FIG.
In FIG. 3, portions other than the display 107 are omitted for the sake of explanation. For the sake of explanation, four vertices of the display 107 are A, B, C, and D, and each side is a side AB, a side BC, a side CD, and a side DA.

As shown in FIG.
In a case where five meeting attendees 116 to 120 exist on the four sides of 07, two persons and two sides B
It is detected that one conference attendee is sitting on each of C, side CD, and side DA. Next, line segments AE and E are obtained by equally dividing each side by the number of conference attendees sitting on each side.
B, BC, CD and DA are obtained, and the midpoint a of each line segment,
b, c, d and e are determined.

A division point for dividing an area is determined as a point where the distance between two points is defined by the length of a line segment on the side and the length is bisected. For example, a point that divides between two points a and b is a middle point E of the line segment ab. Also, point b
Since the distance between the two points b and c is the sum of the line segment bB and the line segment Bc, the distance between the two points b and c is (bB + Bc) / 2, ie, point F on side BC.

When the division points are obtained in the same manner, the point which divides between the two points c and d is point C, the point which divides between the two points d and e is point D, and point D A point that divides between two points e and a is a point G whose distance from the point e is (eA + Aa) / 2
Becomes A straight line connecting the obtained points E, F, C, D, and G and the center point O of the display 107 is a boundary line that divides the personal area for each conference attendee.

At the center of the display 107, there is a common area of a predetermined size. Therefore, by superimposing the boundary of the common region and the boundary line obtained by the above-described procedure and obtaining the intersection of these boundary lines, the vertices of the polygon constituting the final personal region are obtained. For example, as shown in FIG. 14, when the area of the common area 121 is set in advance as an area consisting of the square HIJK, the personal area 122 of the conference participant 116 is a polygon AEMHLG, and the personal area 122 of the conference participant 117 is
3 is a polygon EBFNIM, the individual area 124 of the conference participant 118 is a trapezoid FCJN, and the personal area 1 of the conference participant 119.
25 is a trapezoidal CDKJ, and the personal area 126 of the meeting attendee 120 is a trapezoidal DGLK.

As described above, the personal area allocated to each conference participant by performing the area division processing is represented by the same format as the coordinate information shown in FIG. 4 of the first embodiment, for example.
It is registered in the storage unit 112.

When the area is divided, it is necessary to register an electronic pen used by each conference participant in each personal area. This registration can be performed according to the flowchart shown in FIG. 5 of the above-described first embodiment, and a detailed description thereof will be omitted.

Next, a case where the number of conference attendees increases or decreases during a conference will be described. FIG. 15 is a flowchart showing an area dividing procedure when the number of conference attendees increases, FIG. 16 is an explanatory diagram showing a state where the number of conference attendees has increased, and FIG. 17 is as shown in FIG. FIG. 9 is an explanatory diagram showing an area division procedure when the number of conference attendees increases.

The person detecting section 109 constantly monitors the state of the person around the table 108 (step S21). In this state, it is determined whether or not the area division button has been pressed (step S22). If the area division button is pressed when a new conference attendee is seated, step S2
The answer to 2 is affirmative, and the seating position of the new conference attendee is acquired from the human detection unit 109 (step S23). FIG.
In the example shown in FIG. 6, it is detected by the human detection unit 109 that the new participant 127 is seated on the side BC, and the seated position is sent to the CPU 111.

The CPU 111 performs a region re-division process on the display 107 based on the sent seating position of the conference attendant (step S24).

This re-division processing is performed by a method similar to the above-described area division processing. Then, using the obtained result, the area existing before the subdivision, that is, the common area 1
The coordinate information is updated for the personal area 21 and the individual areas 122 to 126 (step S25), and new coordinate information is created for the personal area 128 for a new conference attendee and registered in the storage unit 112 (step S25). Step S26).
As a result, as shown in FIG. 17, the coordinate information of the personal area 123 of the conference participant 117 is updated from the polygon EBFNIM to the trapezoidal EBIM, and the personal area 123 of the conference participant 118 is updated.
4 is updated from the trapezoid FCJN to the trapezoid BCPI, and the personal area 125 of the conference participant 119 is updated from the trapezoid CDKJ to the trapezoid C'DKJ '. Also new meeting attendee 1
The 27 individual areas 128 are registered as polygons cCC'J'JP. The personal area 128 of the new conference attendee 127
For, registration of the electronic pen is performed by the method described above.

In the case where the number of conference attendees decreases, if the area dividing button is pressed when the conference attendee leaves the table, the human detection unit 109 detects which conference attendee has left. Then, the number of persons on the side where the meeting attendees are seated is reduced by one, and the division is performed again. Then, after the re-division, the coordinate information indicating the area of the conference participant who has left is deleted from the storage unit 112, and the coordinate information of the personal area whose boundary coordinates have been changed is updated accordingly.

As described above, according to the present embodiment, the personal area can be appropriately and automatically divided according to the seat position of the conference attendee, and the number of conference attendees increases or decreases during the conference. Even in this case, the area can be easily re-divided.

(Fourth Embodiment) Next, a fourth embodiment of the present invention will be described with reference to FIG. In the present embodiment, the method of dividing the display screen of the display 107 is different from the dividing method described in the third embodiment. That is, according to the method shown in the third embodiment, the individual area is a polygon having various shapes, but according to the method described in the present embodiment, the individual area is a rectangle or a combination of rectangles. Becomes By making the personal area a rectangle or a combination of rectangles, when one point on the display surface of the display 107 is designated by using the electronic pens 101 to 106, the area where the designated point is located is determined by the rectangle. Can be determined only by comparing the coordinates of the diagonal point with the coordinates of the designated point.

FIG. 18 is a diagram showing a procedure for dividing the area of the display screen of the display 107 performed in the electronic information display device according to the present embodiment. Here, as in the third embodiment, a case in which five conference attendees are seated as shown in FIG. 12 will be described. Display 1
It is assumed that the common area 121 is set in advance on the display screen 07 as shown in FIG.

First, the region excluding the common region 121 is the third region.
By the same method as that of the embodiment, 5 shown in FIG.
Divided into two areas. Thereafter, in order to make the personal area assigned to each conference participant a rectangle, it is necessary to draw a line segment oblique to the side of the display 107 in parallel with the side.

That is, consider a rectangle having a line segment as a diagonal line, divide this rectangle into two equal parts, draw a straight line parallel to the side of the display, and use this as a boundary line. For example, in FIG. 18, when redrawing the line segment NF as a line segment parallel to the side AB, consider a rectangle FN'NF 'having the line segment NF as a diagonal line, and divide this rectangle FN'NF' into two equal parts. Then, a line QR parallel to the side AB is drawn. By such an operation, the line segment NF that has been inclined with respect to the side AB is redrawn into a line segment QR that is parallel to the transformation AB. At this point, since Q is not on the boundary line with the common area, the line segment I
Q will also be part of the new boundary line. With respect to the line segment JC and the line segment KD, when a rectangle having these line segments as diagonal lines is created, two line segments parallel to the sides of the table can be drawn. In the present embodiment, FIG. In this way, the boundary line is drawn so that the personal area becomes wider rightward on the side closer to the side where the conference participant is seated. Therefore, the line segment JC is redrawn into a line segment ST parallel to the side BC. Therefore, the personal area 124 of the conference participant 118 is a combination of the rectangle RjJQ and the rectangle jCTS.

Similarly, the personal area 122 of the conference participant 116 is a combination of the rectangle XAYW and the rectangle YEMH, and the personal area 123 of the conference participant 117 is the rectangle EZI.
Combination of M and rectangle ZBRQ, conference participant 1
19 is a combination of the rectangle TkKS and the rectangle kDVU, and the personal area 125 of the conference participant 120 is
6 is a rectangular VXWU.

As described above, according to the present embodiment, the personal area of each conference participant is an area composed of a combination of a rectangle and a plurality of rectangles. Therefore, the display 10 is displayed using any of the electronic pens 101 to 106.
In the case where a point on 7 is designated, it is possible to determine which area the designated point is in by simply comparing the diagonal point of the rectangle with the coordinates of the designated position. It is very easy to determine whether or not writing to a personal area using is effective as compared with the above-described embodiment.
