Abstract

PURPOSE:To enable 3-element batch inputting by providing an indicator section with an angle sensor to input an angle of inclination. CONSTITUTION:Firstly, an operator puts a distance in directions X and Y from a reference point 0 on a tablet A with the tip of a stylus pen to input a two-dimensional data (two elements). At the same time, when the pen B is tilted to the tablet A, a mobile plate 1 is turned toward the pen B so that a mark 2 traverses a photosensor 3 sequentially from the lowest part to the upper part. The number of mark 2 traversing the sensor is counted to detect an angle of inclination of the pen B. Therefore, if the angle of the inclination is made to correspond to a position data in a three-dimensional Z direction beforehand, a position data of the three-dimensional (three elements) order is inputted with a tilting operation of the pen B to enable three-element batch input. Thus, a clear reference is obtained for a height position thereby achieving higher accuracy of an input data.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a point device, and more particularly to a point device for inputting data to electronic equipment or the like.

[0002]

2. Description of the Related Art Conventionally, when inputting two-dimensional position data on a plane to electronic equipment, point devices having various position sensors have been widely used. In the case of collectively inputting three-dimensional position data using such a point device, first, the position sensor is held in a floating state in the free space (that is, the position sensor is operated by a finger or the like). Next, the position of the position sensor itself at that spatial position is measured three-dimensionally using magnetism or light. Then, by sending the measured values to the electronic device, the three-dimensional position data could be collectively input.

[0003]

In the conventional point device as described above, when the three-dimensional position data is collectively input, the standard for performing the pointing work in the free space tends to be unclear. In addition, since a three-dimensional position measuring device is required separately from the point device, the whole device is increased in size and data input is troublesome. In order to solve such a problem in the conventional technique, the present invention provides a relatively small point device by improving the point device, enabling collective input of three elements and obtaining a clear reference for three-dimensional data. The purpose is to

[0004]

In order to achieve the above object, the present invention provides a point device having an indicator for inputting two-dimensional position data on a plane, and an angle sensor for inputting an inclination angle of the indicator. It is configured as a point device characterized by being provided in the instruction unit.

[0005]

According to the present invention, an angle sensor for inputting the inclination angle of the pointing portion of the point device is provided in the pointing portion.
As a result, it is possible to obtain a relatively small-sized point device that can input three elements at a time and can obtain a clear reference for three-dimensional data.

Embodiments of the present invention will be described below with reference to the accompanying drawings for the understanding of the present invention. The following embodiments are examples of embodying the present invention and are not intended to limit the technical scope of the present invention. Here, FIG. 1 shows a point device P according to an embodiment of the present invention.
FIG. 2 is an external perspective view showing the whole of FIG. 2, FIG. 2 is an explanatory view showing an operating state of the stylus pen, and FIG. 3 is a sectional view showing a schematic structure of an angle sensor incorporated in the stylus pen. As shown in FIG. 1, the point device P according to the present embodiment has a tablet A set in the horizontal direction for inputting two-dimensional position data, and a stylus pen B (corresponding to an instruction unit) that indicates the input position to the tablet A. ) And an angle sensor C which is built in the stylus pen B and detects the tilt angle of the stylus pen B. As shown in FIG. 3, the angle sensor C includes a movable plate 1 with a weight that is rotatably supported in the upper part of the stylus pen B, and a light beam attached to the movable plate 1 at a substantially equal interval in the circumferential direction. It is composed of a reflective mark 2 and an optical sensor 3 which irradiates the mark 2 with light and detects the reflected light. Operation of the point device P is shown in FIGS.
Will be described below with reference to. That is, as shown in FIG. 1, the operator first presses the distance from the reference point 0 on the tablet A in the X and Y directions with the tip of the stylus pen B. By this operation, two-dimensional data (two elements) can be input. Simultaneously with this operation, the stylus pen B is tilted with respect to the tablet A as shown in FIG. The tilt angle of the stylus pen B at this time is detected by the angle sensor shown in FIG.

That is, when the stylus pen B is perpendicular to the tablet A, the lowermost one of the marks 2 attached to the movable plate 1 is detected by the optical sensor 3. Next, when the stylus pen B is tilted with respect to the tablet A, the movable plate 1 causes relative movement (rotation) with respect to the stylus pen B. Along with this, Mark 2
Will cross the optical sensor 3 in sequence from the bottom to the top. By counting the number of the crossing marks 2, the tilt angle of the stylus pen B is detected. Therefore, if the tilt angle and the position data in the three-dimensional direction (Z direction) are associated in advance, the three-dimensional (third element) position data is input by the tilt operation of the stylus pen B. (For example, in FIG. 2, when the tilt angle of the stylus pen B is between 15 degrees and 85 degrees, Z = 0 to Z =
It corresponds to 1. As described above, in the point device P of the present embodiment, the three elements can be collectively input in the state where the stylus pen B is in contact with the tablet A having a reference, and the height position can always be input with a clear reference. Therefore, the accuracy of the input data can be improved. Further, since a three-dimensional position measuring device as in the conventional example is not required, it can be used as a relatively small point device, and it is possible to realize a small portable terminal device in which three elements can be collectively input by a simple operation. it can. Furthermore, it can be compatible with the conventional two-dimensional data input method (mouse, etc.) and unify the man-machine interface. Although the position data is handled as the input data by the point device P in the above-mentioned embodiment, it is possible to handle the elements other than the position data in actual use. For example, if the inclination angle detected by the angle sensor C is associated with the force (F), the two-dimensional position (X, Y) and the force (F) applied to this position can be input at the same time. It can be created in a short time. As described above, the present invention has a wide range of applications.

[0008]

Since the point device according to the present invention is configured as described above, the three elements can be collectively input while the stylus pen is in contact with the tablet having the reference, and the height position can be input. Therefore, a clear standard can always be obtained, and the accuracy of input data can be improved.
Further, since a three-dimensional position measuring device as in the conventional example is not required, it can be a relatively small point device, and it is possible to realize a small portable terminal device capable of collectively inputting three elements. Furthermore, the man-machine interface can be unified by providing compatibility with conventional two-dimensional data input methods (mouse, etc.). Furthermore, since it can handle various elements, it has a wide range of applications, and for example, stress analysis models can be created in a short time.
