Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a mouse with a resolution control mechanism.

[Prior art]

Mouses for cursor movement and pointing on personal computers, etc., have different methods of detecting the amount of movement.
There are types such as mechanical type, optical type, and green bamboo type. Further, there are various variations in the number of pointing buttons and the interface method with the connected main device. Putting these together, it can be said that it generally consists of the following components:

(13X, Y-axis movement sensor (2) Button switch (3) Data multiplexer (4) Host interface X and Y axis movement data, button switch data.

Since mouse data consists of multiple bytes, it is decomposed by a data multiplexer and sent to the host system through the host interface.

The information that the host system receives from mouse operations consists of data regarding displacement in the X-axis direction and Y-axis direction per unit time and the state of the mouse button.

Displacement dx in the X-axis direction of the mouse on the work surface, displacement dy in the Y-axis direction, and X of the cursor on the display.
Between the displacement dx in the axial direction and the displacement dy in the Y-axis direction, v/dX2+dY2=ai d y 2 ----------
■There is a relationship. This proportionality constant a is called a resolution coefficient. Generally, the host system that inputs dx and dy uses software to multiply them by a resolution coefficient to obtain the displacement of the cursor movement. As the resolution factor increases,
Since the displacement on the display increases relative to the displacement on the work surface, K is efficient when you want to move over a long distance, but the resolution becomes coarse and it is not possible to express fine movements. On the other hand, if the resolution coefficient becomes small, it is possible to express fine movements, but it is not suitable for moving over long distances.

In traditional mice, the resolution factor is either fixed or
It is often set semi-fixed using utility software etc. at the beginning of work. However, some devices dynamically change the resolution coefficient in response to the speed, acceleration, etc. of mouse movement.

[Problem that the invention seeks to solve]

When performing operations using a mouse, you may want to move the cursor on the display by a small amount of mouse movement, or you may want to move the cursor on Nice Play to an accurate position even if you move the mouse a large amount. There is. In the conventional mouse mentioned above, the resolution coefficient was fixed and could not be changed without using utility software, but by combining high-speed mobility and accuracy, it can flexibly respond to various operating situations. I can't. Furthermore, the method of dynamically changing the resolution coefficient in response to the mouse speed and acceleration has the drawback that the operator is often unable to control the movement speed and acceleration as intended.

[Means to solve the problem]

The mouse of the present invention includes a movement amount detection means that generates movement amount data in response to a movement operation of the main body, a switch means that generates binary data for instructions in response to an intermittent operation, and a rotatable operation section. a volume output that generates instruction value data whose value changes in response to a rotational operation, and a multiplier that multiplies the movement amount data by a coefficient of a value corresponding to the instruction value data and outputs the result. 9. [Example] Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

In this figure, the mouse can be roughly divided into a sensor section 1 that includes movement sensors, switches, etc., a control section 2 that secures and formats data from the sensor section 1, and a host system that inputs mouse data and uses it for applications. The interface unit 3 is configured to manage and control the interface.

The sensor unit l includes an X-axis sensor 11 for detecting the amount of mouse movement in the X-axis direction, and a Y-axis sensor 1 for the Y-axis direction.
2, two switches 13 and 14, and a volley-
Equipped with 15t. At least the elements in the sensor section l need to be mounted inside the mouse body, and the control section 2. The interface unit 3 may be mounted inside the mouse body or may be realized as an external circuit.

Generally, the X-axis sensor 11. Each output of the Y-axis sensor 12 is a pulse signal corresponding to the amount of movement in each coordinate direction, and these are input to the X-axis counter 21 and Y-axis counter 22 in the control unit 2, respectively, and are converted into count data indicating the amount of movement. converted. Further, the signal sent from the volume 15 is an output voltage divided by a DC voltage fully variable resistor, and this is converted into digital data by an analog/digital (person/L) converter 23.

The digital data output from the A/D converter 23 is input to the resolution coefficient control circuit 24 and the control coefficient k is input to the resolution coefficient control circuit 24.
is converted to The control coefficient is a coefficient that weights the resolution coefficient, and the resolution control circuit 24 determines several levels of control coefficient k in accordance with the digital data value of the volume output. For example, if the control coefficient kl corresponds to the center value of the digital data of the volume output,
Corresponding to its upper and lower values, 2, 3-1- and 1/2, 1
/3-m-. The control coefficient is determined by the X-axis counter 21. It is input to a multiplier 259 and a multiplier 26 together with the count data held in the Y-axis counter 22, multiplied by each coordinate axis movement amount count data, and output.

The movement amount of each coordinate axis multiplied by each output data of multiplier 25 and multiplier 26, and switches 13 and 1
Each binary data indicating on/off from 4 is input to the multiplexer 27 and formatted into the 3-byte data format shown in Table 1 as data to be sent to the host system.

Table 1 In this embodiment, since each coordinate axis movement amount count data is expressed in 10 bits, the first byte contains a flag SF indicating that there has been a change in switches 13 and 14, and a flag SF indicating that there has been a change in switches 13 and 14. SWI, SW indicating on/off status
In addition to 2, the upper 2 bits of each movement amount count data XC
9-8. YC9-8 are included, and the second and third bytes are composed of the lower 8 bits (XC7-O, YC7-0) of the multiplied X-axis and Y-axis count data, respectively.

The interface unit 3 sends these data to the host system in a predetermined format.

In addition, the X-axis counter 21. The count value of the Y-axis counter 22 is reset in preparation for the next transmission when data is input into the multiplexer 27.

In the host system, the cursor movement fk is determined from the amount of movement of each coordinate axis of the mouse, as in the conventional technology.

Since the amount of movement of each coordinate axis of the mouse is multiplied by
i completed 39910. ■ This means that the resolution coefficient a has been multiplied by a.

In this example, all control of resolution coefficients is performed by the controller 2.
The advantage is that this function can be implemented without changing the software in the host system.

FIG. 3 is a perspective view showing the appearance of the mouse body of this embodiment. The mouse 31 is normally used by grasping it with the right hand and placing the index and middle fingers on the switches 32 and 33, respectively. At that time,
The knob is arranged so that the volume 34 can be operated naturally with the thumb. Note that the switches 32 and 33 and the volume 34 are the switches 13 and 14 in FIG. 1, respectively.
and the operation part of the volume 15. The mouse 31 is connected to the computer main body via a cable 35. Further, a protrusion is provided so that the center position of the volume 34 can be sensed without checking with the naked eye, and a spring is attached to the dial of the volume 34 so that the center position is always indicated when the volume 34 is not operated.

Based on the resolution coefficient when the dial of the volume 34 is at the center, turning the dial in the 10th direction increases the resolution coefficient by 2 times or 3 times, and turning it in one direction increases the resolution factor by 1/2 times or 1 times.
/3 times smaller.

〔Effect of the invention〕

As explained above, by making it possible to dynamically change the resolution coefficient of the mouse, the amount of cursor movement on the display when moving the mouse over a distance can be controlled simply by controlling the volume. Can be switched. In other words, even if you move the same distance with the mouse, you can move the cursor either large or small, which has the effect of improving operability.
