When the data input by the two-dimensional position data input method is used as it is in a device using the two-dimensional position data input method, the distance between the input device and the detection device cannot be displayed as information. . That is,
Although it is possible to measure the distance between the input device and the detection device from the three-dimensional positional relationship, it cannot be displayed as information on a two-dimensional screen, so the operator determines the distance between the devices. Can not do it. SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to convert data input by a three-dimensional position data input method into two-dimensional coordinate information and height information. Accordingly, it is an object of the present invention to provide a data input device capable of confirming a distance between an input device and a detection device. In order to achieve the above object, a data input device according to a first aspect of the present invention comprises: an input device for pointing to an arbitrary spatial position; A detecting device for detecting three-dimensional position information, and an operation for converting the three-dimensional position information into a distance between the input device and the detecting device.

And outputting the display information for changing the shape of the pointing figure. According to the above configuration, first, the three-dimensional position information of the input device is detected by the detection device. The three-dimensional position information is input to the calculation unit of the processing device by the input device and the detection device.

Since the display changes according to the magnitude of the distance , the distance between the input device and the detection device can be visually determined. That is, the position of the input device can be easily confirmed on the screen of a device using the two-dimensional position data input method, such as a personal computer, an electronic organizer, and a portable terminal. Further, since the position of the input device can be confirmed, it is possible to prevent the input device from being lost. When three-dimensional position information is detected using ultrasonic waves or radio waves, there is a limit to the inputtable range, so that the inputtable range can be visually detected.

In addition, by providing a time interval for successive pattern changes, it is possible to determine the distance between two devices with respect to a time axis . Embodiment 1 The first embodiment of the present invention will be described below with reference to FIGS. 1 to 4. The case where the data input device according to the present embodiment is applied to a personal computer will be described. As shown in FIG. 2, the personal computer includes an input device 11, a detection device 12, and a processing device 1.
3, and an output device 14. The input device 11 is, for example, a pen-type pointing device, and has an arbitrary spatial position (three-dimensional position).
It indicates. The detection device 12 includes the input device 11
In addition to detecting an arbitrary spatial position pointed by as position information, the detected spatial position information is stored.
The processing device 13 converts the spatial position information into position information on a specific plane and an axial direction orthogonal thereto, and performs processing for outputting and displaying based on the information. The processing device 13 also stores the converted position information and stroke data. The output device 14 performs display based on the display information on which the output display process has been performed by the processing device 13. In FIG. 2, three dotted lines connecting the input device 11 and the detection device 12 indicate communication means such as an ultrasonic wave and a radio wave, and the coordinates of an arbitrary point in the space are at least an arbitrary three. This indicates that the distance is represented by a distance from a point (four points when positive / negative discrimination is performed). Next, based on the block diagram shown in FIG.
The configuration of the data input device will be described. The pen-type pointing device serving as the input device 11 has a transmitting section 21 at the tip of the pen, which can transmit ultrasonic waves, radio waves, and the like. When the operator performs an input operation, the transmission unit 21 performs transmission by ultrasonic waves or radio waves. The detecting device 12 includes a receiving unit 22 and a detecting unit 2
3 The receiving unit 22 receives the ultrasonic wave, the radio wave, and the like transmitted from the transmitting unit 21. This receiving unit 22
The position detector 23a in the detector 23 detects arbitrary spatial position information based on the information received by the
3 stores the spatial position information. The processing device 13 includes a CPU 24, four storage units 25 to 28, and a power supply unit 31. An arithmetic unit 24a inside the CPU 24 extracts arbitrary spatial position information stored in the storage unit 23b and converts it into coordinate information on a specific plane and height information in an axial direction orthogonal to the plane. The storage unit 25 stores the converted plane position and height information. That is, when the input device 11 is arbitrarily moved to draw a pattern in a space, the pattern is converted into a pattern on a specific plane, and then stored in the storage unit 25. It should be noted that, during the arithmetic processing inside the CPU 24, the storage unit 2
4b is used. Here, when stroke data recognition is necessary, the calculation unit 24a recognizes the pattern stored in the storage unit 25 as stroke data and compares it with the stroke data 26a stored in the storage unit 26. If font data is required as a result of the comparison, the font data 27a stored in the storage unit 27 is used. At this time, the pointing figure data 28a stored in the storage unit 28 is used as the pointing figure indicating the pointing position on the display screen. Here, the instruction figure data 28a
Has data of the color (hue / saturation / brightness) of the designated figure. An input / output unit 24c inside the CPU 24
Performs a process for outputting and displaying data obtained from the storage units 25 to 28, and outputs display information. At this time, the instruction figure data 28a is changed and output based on the height information stored in the storage unit 25. The power supply section 31 includes a power supply circuit 31a and a driving battery 31b, and supplies power to the entire apparatus. The output device 14 is an LCD (liquid crystal)
a display control unit 29 such as a driver, and a display unit 30 such as an LCD. Based on the display information obtained by the input / output unit 24c, the display control unit 29 performs control for displaying on the display unit 30, and performs display on the display unit 30. The operation of the data input device according to the above configuration is as follows.
This will be described with reference to the flowchart shown in FIG. First, step (hereinafter abbreviated as S) 1
Then, spatial position information is input by the input device 11 and the detection device 12. This spatial position information is stored in the storage unit 23b in the detection device 12 (S2). Then, the spatial position information is converted into coordinates and height on a specific reference plane (S3). The converted coordinates and height are the processing unit 1
3 is stored in the storage unit 25 (S4). Based on the height information stored in S4, the color (hue, saturation,
The brightness is changed (S5). Output display is performed based on the data processed in S5 (S6). For example, the detection device 12 with respect to the reference plane
If the height is high, the density of the pointing figure is displayed dark. one
On the other hand, when the height of the detection device 12 with respect to the reference plane is low
Displays the density of the designated figure lightly. So in this case
Sets the height of the detection device 12 with respect to the reference plane to a shade of color.
This is shown. Next, the conversion of the spatial position information in S3 will be described. For example, suppose that a point P1 (xl, yl, z1), which is arbitrary spatial position information, is input as shown in FIG. At this time, assuming that the specific plane is plane α: ax + by + cz = 0 as shown in FIG. 4B, the distance L between the point Pl and the plane α is L = | axl + byl + czl | / (a ² + b ²⁾ + C ² ) ^1/2 . The normal vector of a specific plane is (a,
b, c), a straight line drawn perpendicularly to the plane α from the point P1 is a point Pl and a point (xl-a, y1-b, z
1-c). Therefore,
The point obtained by converting the point P1 onto the plane α can be obtained as an intersection M between the perpendicular drawn from the point P1 to the plane α and the plane α. As a result, the spatial position information (point P1) can be converted into coordinates on a specific plane (intersection M) and a height (distance L) in an axial direction perpendicular to the plane. In addition,
The specific reference plane required in S3 may be set in advance from data of at least three points in space before data input. As described above, the data input device according to the present embodiment converts the spatial position information into arbitrary plane coordinate information and height information, and changes the designated figure data based on the height information. This is a configuration for performing display. Therefore, it is possible to visually determine the distance between the detection device and the input device, and to determine the position of the input device on the screen of a device using a two-dimensional position data input method, such as a personal computer, an electronic organizer, and a portable terminal. It can be easily confirmed. Also,
Since the position of the input device can be confirmed, it is possible to prevent the input device from being lost. In the case where an ultrasonic wave or a radio wave is used for the detection device, there is a limit in the inputtable range. Therefore, there is an effect that the inputtable range can be visually detected. Further, when used in a computer game or the like, since it is possible to control the input device and the detecting means based on the positional information, it is possible to produce a game having a higher level of realism and a game having more fun and understandability. It can be carried out. Further, since the color of the pointing figure on the output device is changed, the hue, saturation, or brightness of the pointing figure on the screen changes in accordance with the height information . For example, when the brightness is changed, the distance from the detection device to the input device can be easily determined even if the operator is color blind. [0036] will be described with reference to FIGS. 5 and 6 a second embodiment of the [Embodiment 2] The present invention is as follows.

The operation of the data input device having the above configuration is described as follows.
This will be described with reference to the flowchart shown in FIG . First, S1 to S4 described in the first embodiment
A distance conversion process is performed instead of the height conversion of the spatial position information (S21). Based on the stored height information, the shape, such as the size, orientation, and design, of the pointing figure is changed (S22). Output display is performed based on the data processed in S22 (S23). For example, as shown in FIG. 6 (a) , when the detection device 12 and the input device 11 are in a short-distance positional relationship, the shape of the pointing graphic like the graphic C is displayed in a large size.
On the other hand, as shown in FIG. 6B , when the detection device 12 and the input device 11 are in a long-distance positional relationship, the shape of the pointing graphic like the graphic D is displayed small. That is, in this case, the distance between the two devices is indicated by the size of the pointing graphic. As described above, the present data input device changes the shape of the pointing graphic on the output device, so that the size and orientation of the pointing graphic on the screen correspond to the distance between the input device and the detecting device. Or the design will change. Thereby, for example, when a design such as a portrait is changed, it is possible to improve the interest and intellectual curiosity.
