Abstract

PURPOSE:To hold and move a mouse in a state of an operator can easily handle it by determining a cursor moving direction on a display picture in a mouse moving direction while a mouse device is rotated in an arbitrary angle. CONSTITUTION:The rotation angle of a mouse device 4 is set beforehand by a method in which, for example, a motion of the device is executed in the X direction which is a new coordinate axis with the device itself rotated at a fixed angle, then, when the rotation angle is assumed as alpha based on an X direction moving quantity and a Y direction moving quantity outputted from the mouse device 4, rotation angles sin alpha and cos alpha of the coordinate axis are determined. For the moving quantity of the mouse device 4 in new coordinate axis X and Y directions to display the cursor to a picture, when the mouse device 4 is moved, operation is executed by using X and Y direction moving quantity components to the inherent X and Y direction coordinate axes outputted from the mouse and the rotation angle obtained earlier, and moving quantity components X' and Y' for the new coordinate axis are obtained.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a cursor display processing method using a mouse device, which is a pointing device. This invention relates to a cursor display processing method on a display screen that corresponds to movement.

[Conventional technology]

Conventionally, pointing devices used in word processors, personal computers, and the like include trackball devices and mouse devices, such as those disclosed in Japanese Patent Laid-Open No. 51-83737.

The mouse device is convenient for fully utilizing graphic functions, as it allows the user to freely move a cursor on the display screen, select menus on the screen, and draw arbitrary shapes.

Incidentally, conventionally, a certain relationship has been set between the moving direction of a mouse and the moving direction of a cursor on a screen. Specifically, when the mouse device itself is oriented in a certain direction and the entire mouse device moves in the X direction, the cursor on the screen also moves in the X direction.

[Problem that the invention seeks to solve]

However, in the above-mentioned conventional technology, when the cursor is moved in a straight line in the X direction on the screen, the angle of the mouse itself is, for example.

The mouse device had to be moved in the X direction on the operating desk after setting the angle to a predetermined angle. Also, when trying to display and move the cursor in the X direction, the angle of the mouse device itself should be kept at the same angle as when moving in the X direction, and in that state, move the mouse to the
I had to move in the direction. In other words, in the past, there was a fixed relationship between the direction of movement of the cursor and the angle maintained by the mouse device itself, and while there were individual differences in how the mouse was held, The holding angle was forced by the system, making it difficult to use from an operational standpoint.

The present invention has been made in consideration of the above points, and includes:
The purpose of this is that no matter what angle the mouse device itself maintains, if you set the tilt angle by - degrees, even if the mouse device itself is tilted, the direction of mouse movement and the cursor will be fixed. The object of the present invention is to provide a cursor display processing method using a mouse device with improved operability, which can match the moving direction of the mouse.

[Means for solving problems]

The purpose is 1 to have the control device detect and store in advance an arbitrary rotation angle with respect to the X direction and the X direction coordinate axis that the mouse device originally has, and to change the movement direction of the mouse device by this arbitrary rotation angle. The rotation of the reference X direction and X direction coordinate axes is assumed to be the new X direction and X direction coordinate axes, and the amount of mouse movement corresponding to the cursor display determines the amount of movement with respect to the new coordinate axes. This is achieved by

[Effect]

Therefore, in the present invention, the rotation angle of the mouse device that is preset is 1. For example, when the mouse device itself is rotated by a certain angle, by moving the mouse device in the X direction, which is a new coordinate axis, the mouse device can be moved at that time. Based on the amount of X-direction movement and the amount of X-direction movement output from the device, if the rotation angle is α, the rotation angle of the coordinate axis is
α and cosα are determined.

Also, a new coordinate axis x to display the cursor on the screen
, the movement amount of the mouse device in the Y direction is determined by the original X output from the mouse when the mouse device is moved, the x and X direction movement amount components relative to the X direction coordinate axis, and the rotation angle α obtained earlier. By performing calculations using
The movement amount components X' and Y' with respect to the new coordinate axes can be determined.

Therefore, when the mouse device 4 is moved, for example, in the X direction in FIG. 4, only the 44X friction roller rotates, and only the number of movement pulses in the X direction is output from the mouse device 4.

FIG. 8 is a diagram showing the relationship between the moving direction of a conventional mouse device and the cursor moving direction on the display screen.

The amount of movement of the mouse on the operating desk is divided into the X direction and the X direction, and the number of movement pulses is output from the mouse device 4, as shown in the mouse configuration diagram in FIG. As shown in the mouse movement diagram in Figure 8, when the mouse moves in the direction of θ with respect to the X-direction coordinate axis, the amount of movement X in the X direction is: X=Lcosθ The amount of movement Y in the X direction is , Y = L sin θ The number of pulses will be output, and based on the values of the mouse movement amount X and Y, as explained in FIG. 3, on the main body 1 side of FIG. 2, The position of the cursor on the display screen is calculated, the cursor follows the movement of the mouse, and a predetermined display is performed.

Further, the cursor is moved at an appropriate ratio to the amount of mouse movement corresponding to the screen size.

FIG. 1 is a diagram showing the relationship between the moving direction of a mouse and the moving direction of a cursor on a display screen according to the method of the present invention.

In FIG. 1, the angle α is a corrected rotation angle of the mouse body, which is set in advance by the operator. Further, in FIG. 1, the X coordinate axis and the X coordinate axis on the mouse operating desk are pulse output reference axes determined by the encoder position within the mouse body, respectively. This Xt'!

It becomes possible to move the mouse imaginatively and draw a cursor on the display screen. The relationship between the moving directions of the mouse and the cursor after the correction is made as described above is based on the relationship that the new y' direction becomes the horizontal direction on the display screen, and the new y' direction becomes the vertical direction. , the cursor is displayed moving.

Then, if the correction angle set by the operator is α, the amount of movement of the mouse in the X′ direction with respect to the new coordinate axis, the X′ direction axis, is
', and x, y, and α are known, and from the relationship between sine and cosine, the following formula is obtained: X' can be obtained as follows.

X' = X1 + X2 = X cos α + Y sin rt FIG. 6 is a diagram illustrating how to obtain a new movement amount component of the mouse in the coordinate y' direction after the fixed rotation angle correction is performed, similar to FIG. 5.

Therefore, as explained in FIG. 5, the X and Y direction mouse movement components X, Y, and correction angle α are known, and in FIG. 6, the y' direction movement amount component to be determined is Y' is determined as follows.

Y1=Ycosα Y2=Xsinα Y'=Y1−Y2=Ycos a −X5in a FIG. 7 is a flowchart showing the flow of processing from mouse movement to cursor display in the present invention. The feature is that the operator is required to set the correction angle in advance as a step before normal processing such as moving and displaying and pointing.

In step 86, the control device calculates a new x whose angle is rotated by α from the values of sin α and CoSα calculated and stored in step 84, and the movement amounts X and Y of the mouse itself that have been stored in step 85. The movement amount components X' and Y' with respect to the ', y' coordinate axes are calculated according to the calculation formula. In step 87, the cursor position corresponding to the new mouse movement amount calculated in step 86 is displayed on the display.
