Abstract

PURPOSE:To form a means which detects the coordinate moving amount with use of a moving amount input means by calculating the absolute coordinates of a graphic after moving with the output of a moving amount input means, the output of a rotational angle arithmetic means, and the absolute coordinates of a pattern which is held by an absolute coordinate holding means. CONSTITUTION:When a moving amount input means 1 is turned on a plane, a rotational angle theta=arctan (DELTAY/DELTAX) is obtained by a rotational angle computing means 2 from the differences DELTAX and DELTAY of the X and Y directional moving amounts which are detected by two moving amount detecting means. A coordinate computing means 3 computes and outputs the absolute coordinates of a graphic after movement with the moving amount detected by two moving length detecting means, the rotational angle, and the absolute coordinates of a graphc before movement which is held by an absolute coordinate holding means 4. The absolute coordinates of the graphic after movement are shown by a display means 5 to update the contents held by the means 4. Thus it is possible to form a means which detects the coordinate moving amount with the use of the means 1.

The present invention relates to a graphic information processing device that processes and displays graphic movement information input through a pointing device.

2. Description of the Related Art In personal computers and the like, a pointing scale, such as a mouse, is used to input the amount of movement of a figure.

A conventional mouse has a ball that rotates when moved on a desk, an encoder that detects the amount of rotation of the ball in the X direction, an encoder that detects the amount of rotation of the ball in the X direction, and information about the movement of a figure being input. It has fun keys etc. that indicate the movement of one coordinate representing the figure in the X direction! It was possible to input only the ll amount and the movement amount in the X direction at the same time. However, in recent years, the inventors of the present invention have developed a movement amount detection means consisting of a ball as described above and an encoder for detecting the amount of movement in the X direction and the It proposes a mouse with two mice located at a certain distance from each other.

Therefore, there has been a need for a technique for processing graphic information using a mouse equipped with two such movement amount detection means located at a fixed distance from each other.

Conventionally, no technology has been disclosed for processing graphic information using a mouse equipped with two movement amount detection means located at a fixed distance from each other.

The present invention has been made in view of the above-mentioned problems, and includes two means for detecting the amount of movement of coordinates located at a fixed distance from each other.
It is an object of the present invention to provide a graphic information processing device using a movement amount input means provided with one or more movement amount input means.

FIG. 1 is a basic configuration diagram of the present invention. In this figure, 1
2 is a movement amount input means, 2 is a rotation angle calculation means, 3 is an absolute coordinate calculation means, 4 is an absolute coordinate holding means, and 5 is a display means.

The movement amount input means 1 includes two movement length detection means each capable of detecting a movement length in the X direction and a movement length in the be.

The rotation angle calculation means 2 calculates the rotation angle from the X direction and the movement length in the X direction detected by the two movement length detection means, respectively.

The absolute coordinate holding means 4 holds the absolute coordinates of a figure.

The absolute coordinate calculation means 3 calculates the absolute coordinates of the figure after the movement based on the output of the movement amount input means 1, the output of the rotation angle calculation means 2, and the absolute coordinates of the figure held in the absolute coordinate holding means 4. Calculate coordinates.

The display means 5 displays the absolute coordinates of the figure after the movement calculated by the absolute coordinate calculation means 3.

[For production]

When the movement amount input means 1 is moved in parallel on the plane where the two movement length detection means each detect the movement length, the movement amount detected by the two movement length detection means is However, when the movement amount input means 1 is rotated on the plane, the difference between the movement amounts in the X direction and the X direction detected by the two movement amount detection means, △X and △Y
From this, the rotation angle is determined by the rotation angle calculation means 2 as follows: θ=arctan (ΔY/ΔX).

The coordinate calculation means 3 calculates the figure after movement based on the amount of movement detected by the two movement length detection means, the rotation angle, and the absolute coordinates of the figure before movement held in the absolute coordinate holding means 4. Calculates and outputs the absolute coordinates of the figure.

The absolute coordinates of the figure after the movement are displayed on the display means 5, and the contents held in the absolute coordinate holding means 4 are updated by the absolute coordinates of the figure after the movement.

First, use the first function key of the mouse 11 (not shown) to move the cursor to the position where you want to specify the shape you want to move, as shown in a of 2nd/V], and press the second function key (also not shown). By moving the mouse 11 on the desk as shown in FIG. 2B for a period specified by the function key, the amount of rotation of the two balls in the X direction and the X direction, respectively, input from the mouse 11. The encoder output corresponding to Data of the amount of movement in the X direction and the X direction in the two movement amount detection means Δx1. △Y + , △X2. and ΔY2. These are the arithmetic processing unit 1
Sent to 3.
