Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a posture input mouse for a three-dimensional model used as an input device of a computer utilizing three-dimensional CAD or three-dimensional modeling software.

[0002]

2. Description of the Related Art In a three-dimensional CAD, when a three-dimensional model including a figure is created, the model is displayed on a two-dimensional display screen. You need to enter the y and z coordinate values, or change the pose of the model to see from different directions.

To input the posture change of the model, x, y
Each parallel movement in the direction and rotation about each of the x, y, and z axes are input by using the posture input mouse of the three-dimensional model. As this type of conventional mouse, a plurality of types of posture operation knobs for parallel movement in the x direction and parallel movement in the y direction are attached to the mouse body, and when changing the posture of the model on the screen,
It is known that the above knobs are selected and operated one by one to perform a desired input. In addition, a selection button for selecting multiple types of posture operation menu created by the software and one ball is provided on the mouse body, and the desired posture menu is selected by the selection button, and the ball of the mouse body is selected. Some are known to move.

[0004]

Among the conventional three-dimensional model posture input mice having the above-described configuration, in the former one, when the action of turning the posture operation knob directly moves the model with the hand. Since the senses are different, there is a feeling of strangeness in the operation, and when rotating the model, it is necessary to operate for each of the x-axis, y-axis, and z-axis, and it takes time and skill to change to a desired posture. It is unavoidable that permeation technology is required. Also, in the latter case, it is necessary to create software for displaying the posture operation menu on the screen, which is costly, and the input operation becomes two steps depending on the operation selected from the menu to obtain the desired posture. There is no change in that it requires considerable operation technology.

The present invention has been made in view of the above-mentioned circumstances, and the model can be directly moved at the time of inputting the posture without any special software or the like, so that the model can be operated with a feeling.
It is an object of the present invention to provide a three-dimensional model posture input mouse capable of improving operability.

[0006]

In order to achieve the above object, a three-dimensional model posture input mouse according to the present invention comprises:
Detects the linear displacement due to the parallel linear movement operation on the operation plane of the mouse body and gives the linear displacement along the corresponding direction in the x and y directions to the model on the screen, and on the operation surface On the back side of the mouse body, the first, second and third balls for detecting the rotational displacement due to the rotation operation of the mouse and giving the rotational displacement around the z-axis to the model on the screen are attached to the mouse body. And a fourth ball for detecting a rotational displacement due to a manual rotation operation in the x and y directions and giving a rotational displacement around the corresponding axis of the x axis and the y axis to the model on the screen. It is equipped on the front side of the mouse body.

[0007]

According to the present invention, the mouse body is moved in parallel by operating the mouse body in a parallel straight line on the operation plane.
The three balls provided on the back surface of the model roll to support points, and the model on the screen is linearly displaced in the corresponding x and y directions.
Since it is rotationally displaced around the axis, you can operate it as if you were directly holding the model. You can also rotate the ball on the surface of the mouse body with your finger to rotate the model on the screen in the x-axis and y-axis directions. Since it is displaced, this also gives the feeling of directly moving the model, and it is possible to directly move the model with the hand to change the predetermined posture of the model on the screen without the need to pick up a menu etc. from the screen. It can be done by image operation of feeling.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view schematically showing a computer using a three-dimensional model posture input mouse according to an embodiment of the present invention.

In FIG. 1, reference numeral 1 denotes a computer display, and a model M is displayed on a screen 1F thereof. Reference numeral 2 is a keyboard as an input device connected to the display 1 and 3 is a mouse for posture input of a three-dimensional model as an input device for the display 1, which is used on an operation plane 4 such as a desk top. It has become. The structure of the mouse 3 will be described with reference to FIGS.

2 to 4, on the back surface 5a side of the mouse body 5, the first, second and third balls 6, 7,
8 are provided so as to support the mouse body 5 at three points. These three balls 6, 7, 8 detect the linear displacement when the mouse body 5 is moved in parallel on the operation plane 4 and detect the linear displacement in the corresponding x or y direction with respect to the model M on the screen. It is configured to give a linear displacement along the z-axis and to detect a rotational displacement associated with a rotational operation on the operation surface 4 to give a rotational displacement around the z axis to the model on the screen.

A fourth ball 9 is mounted on the surface 5b side of the mouse body 5. This ball 9
Is configured to detect a rotational displacement due to a manual rotational operation in the x and y directions and to apply a rotational displacement around the relevant axis of the x axis and the y axis to the model M on the screen. ing.

Next, the operation of the above configuration will be described. When the mouse 3 is moved in parallel in the direction shown by the dotted arrow in FIG. 5 while looking at the screen 1F of the display 1, linear displacement is detected by the balls 6, 7, and 8, and the model M on the screen 1F is displaced in the x direction. Can be made Similarly, when the entire mouse 3 is moved in parallel in the direction indicated by the dotted arrow in FIG. 6, the model M can be displaced in the y direction, and further the entire mouse is moved in parallel in the direction indicated by the dotted arrow in FIG. Then, the model M can be displaced simultaneously in the x-axis direction and the y-axis direction. When the mouse 3 as a whole is rotated as shown by a dotted arrow in FIG.
Can be rotationally displaced about the z-axis. They are,
The posture of the model M can be input as if the model M were to be directly moved with respect to the movement on the x-y plane.

Further, when the ball 9 on the front surface 5b side is rotated with a finger or the like in the direction of the dotted line arrow in FIG. 8 while the mouse 3 is left as it is, the rotational displacement by the ball 9 is detected and displayed on the screen 1F. The model M can be rotationally displaced around the x axis. Similarly, by rotating the ball 9 in the direction of the dotted arrow in FIG. 9 with a finger or the like, the model M can be rotationally displaced about the y axis. Furthermore, the model 9 can be rotationally displaced in an oblique direction by changing the rotation direction of the ball 9. Also in this case, since the model M on the screen 1F rotates around the x-axis or the y-axis in accordance with the direction in which the ball 9 is rotated by the finger, it is possible to obtain the feeling of directly rotating the model M with the hand. Come on. In addition, since the posture input may be performed by directly operating the mouse body 5 or the ball 9, it is not necessary to select a menu from the screen 1F and the operability is improved.
