FIG. 3 is a block diagram showing the control system of this embodiment.

The control system of the present apparatus 1 includes an input plate 2, an input pen 3, a digitizer control circuit 13, a CPU 14 as control means, a display drive circuit 15, a display 16, and an input point by the input pen 3. 17 for storing various information including distance information between the icon and the icon 5
It has.

The display 16 is a rear projection type projection display for enlarging and projecting the screen of a CRT or LCD on an input surface or a screen provided behind the input surface, and is driven by the display drive circuit 15. .

The digitizer control circuit 13 uses the input pen 3
When the contact detection switch of the input pen 3 is turned on, the alternating voltage is applied by the oscillating circuit 12 to generate an alternating magnetic field in the pen coil 3a, and this alternating magnetic field causes the X-axis coil group to contact. 6 and a predetermined coil of the Y-axis coil group 7 to generate an induced voltage.

The CPU 14 is a digitizer control circuit 13
The position coordinate by the input of the input pen 3 detected by the above is detected by detecting a point corresponding to the position coordinate or a group of continuously input points at a predetermined sampling rate,
The display drive circuit 15 displays the data on the display 16, which allows pointing by the input pen 3 or writing by the input pen 3. Further, a predetermined icon 5 that can be selected by tapping or the like in the vicinity of the input point by the input of the input pen 3 (position apart from the input point by a predetermined distance), for example, "input mode", "erase mode" as shown in FIG. ", Etc. are displayed, and the selection / execution of the menu command by the pointing, the character recognition for the written information, the figure recognition or the execution of the gesture command can be performed.

Here, the icon 5 is set by the CPU 14 so that the icon 5 is kept displayed for a predetermined time once the input pen 3 is separated from the input plate 2, whereby the operator can input the input pen 3. 3 can be separated from the input plate 2 and the icon 5 can be designated and selected by tapping or the like. Further, when the input pen 3 is separated from the input plate 2 and a new input is made at a place far from the previous input position, the one displayed near the previous input position is erased and a new input point is displayed. It is controlled by the CPU 14 so as to be displayed in the vicinity.

Further, when the input points are continuously input by the input pen 3, the CPU 14 determines the positional relationship between the input points and the icons, and this determination is stored in the memory 17. The determination is made based on the distance information between the input point and the icon, and the determination is made based on the threshold values of the distance when the input point approaches the icon by a predetermined distance and the distance when the input point moves away from the icon. Based on this determination, the CPU 14 determines, for example, the display position of the icon having the first input point (see FIG. 4).
Then, when it comes close to the position (shown by the dotted line), the display position of the icon is changed to a position (the position shown by the solid line in FIG. 4) that is a predetermined distance away from the position of the adjacent input point.

Next, the operation of the present embodiment having the above-mentioned configuration will be described with reference to the flowchart of FIG.

First, when the operator starts the present apparatus and starts inputting with the input pen 3 (S11), the CPU 14
As shown in FIG. 4, icons of "input mode" and "erase mode" are displayed near the input point on the screen by this input (S12). Next, the CPU 14 monitors the coordinates of continuous input points of the input pen 3 (S13), and determines whether the input point is close to the icon in order to determine the positional relationship between the input point and the icon (S14). .

Here, when the input point comes close to the display position of the icon, the CPU 14 changes the display position of the icon to a position apart from the position of the close input point by a predetermined distance (S15).

If the input point is not close to the icon display position, the CPU 14 determines whether the input point is further away from the icon (S16). If the input point is further away, the icon display position is changed to The position of the input point that has moved away is changed to a position separated by a predetermined distance (S1).
7). Here, when the input point is not separated from the icon, the CPU 14 returns to step S13 and again monitors the coordinates of continuous input points of the input pen 3.

Further, the CPU 14 executes the above step S15,
In S17, even after changing the display position of the icon,
Returning to step S13, the coordinates of continuous input points of the input pen 3 are monitored again. In the above step, after changing the display position, the operator can instruct and select the icon 5 by tapping the coordinate indicator or the like as necessary.

In the above configuration, the distance threshold when the input points approach each other may be set to substantially zero, and the position of the icon 5 may be changed after the input pen 3 comes over the icon 5.

According to the first embodiment of the present invention having the above configuration and operation, the necessary icon 5 is displayed in the vicinity of the input point at the time of input, so that the operator can touch these by tapping the coordinate indicator or the like. Can be easily selected. In addition, if the coordinate indicator approaches or touches the icon 5 with one stroke, not for selection, the icon 5 should not interfere with the input.
Since the display position of is changed, a large-screen information processing device with good operability can be realized. Further, this operability is good in the conference and the information processing device, which are considered to be used by an unspecified number of people including beginners, as in the present embodiment.
The effect is extremely high, that is, even a beginner can freely operate the information processing apparatus without being bothered to use the information processing apparatus, so that the purpose of the meeting or the meeting can be easily achieved. (Second Embodiment) Next, a second embodiment of the present invention will be described.

This embodiment has the same structure as that of the first embodiment except for the CPU 14 determining the positional relationship between the input point and the icon 5 and the display operation of the icon 5 based on the judgment. Therefore, the description of the parts related to the overlapping configurations will be omitted.

In the above structure, when the input points are continuously input by the input pen 3, the CPU 14 determines the same amount (direction and length) as the amount of movement of the input points by continuous input. That is, the display position of the icon 5 is controlled to be changed. The movement amount is detected by C
It is performed every sampling of the input points under the control of the PU 14.

Next, the operation of this embodiment having the above configuration will be described with reference to the flowchart of FIG.

First, when the operator starts the present apparatus and starts the input with the input pen 3 (S21), the CPU 14
Similar to the first embodiment, a predetermined icon 5 is displayed near the input point on the screen by this input (S22). next,
The CPU 14 detects the amount of movement of the input point due to continuous input of the input pen 3 (S23), and changes the display position of the icon 5 by the same amount (direction and length) as this amount of movement (S24). After this, the operator may use the input pen 3 if necessary.
The icon 5 can be easily selected by tapping or the like.

In the above description, the movement amount is detected by the CPU.
The method is not limited to the method performed every sampling of the input points under the control of 14, and may be performed by detecting the movement amount of the input points at a predetermined time interval. Further, it goes without saying that this time interval may be configured to be selectively set by the operator.

According to the second embodiment as described above, as the input point moves, the icon 5 moves so as to follow this movement, so that the icon 5 is always displayed at substantially the same position with respect to the input point. Then, the operator can easily select the icon by tapping the pen. Further, it is possible to realize an information processing device having a large screen with a good operability in which the pen does not approach or contact the icon 5 with one stroke, and is easy to input, not for selection.

The present invention is not limited to the above-mentioned embodiment, and various modifications can be made.

For example, the type and number of icons 5 to be displayed may be any, and the operator may select an appropriate icon 5.

Further, the display position of the icon 5 with respect to the input point is not particularly limited, and it goes without saying that the operator may arbitrarily set it. further,
The present invention is not limited to icons, and is also effective for menu commands as other processing command information or other windows that are not the window being input. That is, when the input point approaches the displayed menu command or another window, the menu command or another window may be separated from the input point by a predetermined distance.

The coordinate input method of the present invention is not limited to the electromagnetic induction method of the above-mentioned embodiment, and it is provided with an input plate in which two or more glass plates having transparent resistors or resin films are laminated. The present invention can be applied to any method such as a resistance film method and a so-called ultrasonic wave-based method in which the position coordinates of the pen are derived by detecting vibration propagating in the input plate.

Further, in the above-mentioned embodiment, the coordinate indicator has a pen shape, but it may have a so-called mouse shape. Further, the display method is not limited to the above embodiment.

It is needless to say that the present invention can be applied to information processing apparatuses of various sizes from a small portable size for individuals who can carry in a bag or the like to a large size so-called electronic blackboard size.
