Abstract

PROBLEM TO BE SOLVED: To make it possible to confirm the distance between the input device and a detecting device and prevent the input device from being lost by converting data which is inputted by a three-dimensional position data input system into two-dimensional coordinate information and height information. SOLUTION: The input device 11 is, for example, a pen type pointing device and indicates an arbitrary space position (three-dimensional position). The detecting device 12 detects the arbitrary space position indicated with the input device 11 as position information and stores the detected space position information.

BEST MODE FOR CARRYING OUT THE INVENTION

[Embodiment 1] The following description will discuss Embodiment 1 of the present invention with reference to FIGS. 1 to 5. The data input device according to the present embodiment will be described when applied to a personal computer.

The personal computer, as shown in FIG. 2, has 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).
To point to. The detection device 12 is the input device 11
The arbitrary spatial position pointed to by is detected as position information, and the detected spatial position information is stored.
The processing device 13 converts the spatial position information into position information of a specific plane and an axial direction orthogonal to the specific plane, and performs processing for output display 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 that has undergone the output display process 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 ultrasonic waves and radio waves, and the coordinates of any point in space are at least three arbitrary points. It is shown that it is represented by the distance from a point (4 points when positive / negative is distinguished).

Next, based on the block diagram shown in FIG.
The configuration of the data input device will be described.

The pen-type pointing device which is the input device 11 has a transmitter 21 for transmitting ultrasonic waves or radio waves to the tip of the pen. When the operator performs an input operation, the transmission unit 21 transmits by ultrasonic waves or radio waves.

The detector 12 includes a receiver 22 and a detector 2.
3 The reception unit 22 receives the ultrasonic waves, radio waves, etc. transmitted from the transmission unit 21. This receiving unit 22
The position detecting unit 23a in the detecting unit 23 detects arbitrary spatial position information based on the information received in
The storage unit 23b in 3 stores the spatial position information.

The processing device 13 comprises a CPU 24, four storage units 25 to 28, and a power supply unit 31. The arithmetic unit 24a inside the CPU 24 takes out arbitrary spatial position information stored in the storage unit 23b and converts it into coordinate information on a specific plane and height information in the 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 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 the storage unit 2 is used for the arithmetic processing in the CPU 24.
Use 4b.

If stroke data recognition is required, the arithmetic 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, as the pointing graphic indicating the pointing position on the display screen, the pointing graphic data 28a stored in the storage unit 28 is used. Here, the instruction figure data 28a
Has data on the color (hue / saturation / brightness) of the indicated figure.

An input / output unit 24c inside the CPU 24
Performs a process for outputting and displaying the data obtained from the storage units 25 to 28, and outputs the display information. At this time, the designated figure data 28a is changed and output based on the height information stored in the storage unit 25.

The power supply unit 31 is composed of 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).

The operation of the data input device having the above configuration will be described.
This will be described with reference to the flowchart shown in FIG.

First, step (hereinafter abbreviated as S) 1
Then, the 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 device 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, as shown in FIG. 5 (a), when the detection device 12 and the input device 11 are in a short distance positional relationship, the density of the designated figure such as the figure A is displayed dark. On the other hand, as shown in FIG. 5B, when the detection device 12 and the input device 11 are in a long-distance positional relationship, the density of the designated figure such as the figure B is displayed light. That is, in this case, the distance between the two devices is indicated by the shade of color.

Next, the conversion of the spatial position information in S3 will be described.

For example, assume that a point P1 (xl, yl, z1), which is arbitrary spatial position information, is input as shown in FIG. At this time, if 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 +
It is represented by 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,
A point obtained by converting the point Pl on the plane α can be obtained as an intersection M of the perpendicular line 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 (intersection point M) on a specific plane and the height (distance L) in the axial direction orthogonal to the plane. In addition,
The specific reference plane required in S3 may be preset from at least the coordinates of at least three points in space before data input.

Easy to check. Also,
Since the position of the input device can be confirmed, it is possible to prevent the input device from being lost. When ultrasonic waves or radio waves are used for the detection device, there is a limit to the inputtable range, so there is an effect that this inputtable range can be visually detected.

Further, when used in a computer game or the like, it is possible to control the position information of the input device and the detection means, so that it is possible to manufacture a more advanced and immersive game or a game having more fun and comprehension. It can be carried out.

Furthermore, since the color of the pointing graphic on the output device is changed, the hue, saturation, or lightness of the pointing graphic on the screen changes in accordance with the distance between the input device and the detection device. . 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.
