Abstract

PURPOSE: To use an interface matching human sensations and improve operation efficiency by directly measuring rotational motion in the three-dimensional space of the human hand by using a device which detects static electricity charged on the human fingers. CONSTITUTION: This instrument consists of an input device 1 constituted by sticking the device capable of detecting the position of a human finger from the static electricity charged on the finger on the surface of a sphere and a computer circuit 2 which calculates rotating operation from the position shift of the measured finger. The operator lightly grips the input device 1 with the thumb, index finger and middle finger, and slides the fingers arm the sphere as if the three-dimensional model were rotated. The positions of the respective fingers on the sphere are measured at certain intervals and the rotating direction of this virtual body in the assumption that the body are gripped with the fingers is calculated from the current measurement data and last data, and then outputted.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary motion measuring device, and more particularly to a rotary motion measuring device for directly measuring the motion of a human finger, which is used when inputting / controlling the posture of an object by three-dimensional CAD or the like. Regarding

[0002]

2. Description of the Related Art In three-dimensional CAD, it is necessary to rotate or move a generated model in order to change the viewpoint. Conventionally, in order to measure the movement of rotation, this type of device sets a certain axis, converts a one-dimensional movement by a mouse or the like into a rotation around the axis, or moves the mouse in two dimensions. Can be converted into rotational motion (Japanese Patent Laid-Open No. 63-187371), a trackball can be used, or the force can be decomposed into 6 degrees of freedom to control the freedom of movement and rotation (Japanese Patent Laid-Open No. 62-026532). Etc. were taken.

[0003]

SUMMARY OF THE INVENTION In this conventional technique,
It is difficult to move the model of the posture that one desires by one operation, because the movement in the two-dimensional plane is converted into the three-dimensional rotational movement, the parameters are used, and the operable area is narrow. Not only that, there is a problem that trial and error is required for operation, and enthusiasm is required.

[0004]

A rotary motion measuring apparatus of the present invention directly measures a rotary motion in a three-dimensional space of a human hand by using a device for detecting static electricity charged on a human finger, By calculating the rotation motion from the measured position change of the finger using software in a computer circuit, it is possible to operate as if you were actually grasping the model as you normally do. It has achieved a practical interface for manipulating objects.

[0005]

Next, the present invention will be described with reference to the drawings.

1A and 1B are a perspective view and a block diagram showing an embodiment of the present invention. FIG. 2 is a flow chart showing the calculation procedure.

The rotational movement measuring device is an input device 1 in which a device capable of detecting the position of a human finger from the static electricity charged on the finger is attached to the surface of a sphere, and a device for rotating from a measured position change of the finger. It is composed of a computer circuit 2 for calculating the operation of.

The operator lightly grips the input device 1 with the three fingers, the thumb, the index finger, and the middle finger, and slides the finger on the ball as if rotating the three-dimensional model. The position of each finger on the sphere is measured at a fixed cycle, and based on the current measurement data and the previous data, the rotation direction of this virtual object, assuming that the finger was grasping the object. Is calculated and the value is output.

FIG. 3 is a perspective view showing an application example in which this device is combined with a joystick. The operator can simultaneously perform the posture control and the position movement of the model without switching the mode, and the work efficiency can be greatly improved. By making the joystick part of the device of FIG. 3 a slide type, the number of parameters that can be operated simultaneously can be further increased.

[0010]

As described above, the rotary motion measuring device according to the present invention directly measures the motion of a finger, and therefore provides an interface that suits the human sense, thus improving the working efficiency. Have. Further, since a considerable part of the surface of the sphere can be touched, the operation area is wide, and the posture of the object can be operated by one operation. Further, by combining with a joystick or the like, there is an effect that the posture control and the position movement of the model can be performed at the same time without switching the mode.
