Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mouse device, and more particularly to a mouse device which is one of pointing devices for controlling movement of a cursor on a display screen in an information processing device such as a computer.

[0002]

2. Description of the Related Art In an information processing apparatus, a mouse device is used to control movement of a cursor on a display screen. In this mouse device, the resolution is fixed or a desired resolution is selected from a plurality of preset resolutions, and the movement distance of the device is multiplied by this resolution to determine the amount of movement of the cursor. .

In addition to the moving distance of the device, a function for detecting acceleration is added, and the resolution is changed according to the moving acceleration to obtain a resolution suitable for actual mouse operation. There is one that calculates the cursor movement amount by multiplying the movement distance of the device, and is disclosed, for example, in Japanese Patent Laid-Open No. 63-172327.

[0004]

Due to the operating characteristics of the mouse device, the smaller the resolution, the more suitable for finely operating the cursor on the display, and the larger the resolution, the more suitable for controlling the large movement of the cursor. Usually, these operations are performed in a mixed manner, so if the resolution is a fixed value, the operability will be reduced.

Therefore, in the above-mentioned conventional technique, the operability is improved by not changing the resolution to a fixed value but changing the resolution according to the moving acceleration of the mouse device during the operation. That is, when the acceleration is high, the resolution is increased to increase the cursor movement amount on the display, and in the opposite case, the resolution is decreased to facilitate fine work.

However, in such a conventional system, no consideration is given to the operating environment of the mouse device. In other words, the friction force depends on the difference between the optical mouse device and the bus type mouse device, and in the case of the bus type mouse device, whether it is placed directly on the desk or on the mouse pad. Will be different. If the frictional force is different, the operation pressure required to move the mouse device by the same distance changes. Therefore, it is insufficient to determine the resolution only by acceleration.

An object of the present invention is to provide a mouse device in which the resolution is determined and controlled in consideration of the usage environment of the device.

[0008]

According to the present invention, an acceleration detecting means for detecting an acceleration when the apparatus is moving, a pressurizing detecting means for detecting a pressing force applied to the apparatus, and an acceleration detecting means for detecting the acceleration and the pressing force. And a calculation means for calculating the amount of movement of the cursor.

[0009]

In addition to the acceleration, the pressure applied to the device is taken into consideration to calculate the resolution, and the cursor movement amount is determined by the calculated resolution.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

On the other hand, a pressurization degree sensor 4 is provided to detect the pressure applied to the device, and the detected pressure is input to the calculation unit 6 together with the respective accelerations calculated by the acceleration sensors 3a and 3b. The computing unit 6 computes the amount of movement of the cursor on the display from these three pieces of input detection information.

In 3 and 24, the respective accelerations are calculated from the respective differences of the moving distance per one clock pulse.

Then, in step 25, the resolution due to acceleration is calculated as k1 (dx / dt + dy / dt) using the resolution coefficient k1 (acceleration resolution coefficient) for this acceleration.

At the same time, in step 26, the pressure F applied to the apparatus at this time is detected, and in step 27
In, the resolution by the degree of pressurization is calculated as k2F using the resolution coefficient k2 (pressure degree resolution coefficient) for this pressure.

In step 28, acceleration resolution coefficient (step 25) and pressurization degree resolution coefficient (step 27)
Using and, the total resolution is calculated as k1 (dx / dt + dy / dt) + k2F.

Then, in step 29, this resolution is multiplied by the device movement distance to obtain the final cursor movement amount on the display as {k1 (dx / dt + dy / dt) + k2F} (x +
y)

[0018]

As described above, according to the present invention, when the cursor movement amount on the display is calculated from the movement distance of the device, the resolution is calculated in consideration of the pressing force as well as the acceleration of the device. As a result, it is possible to move the cursor in accordance with the intention of the operator who uses the device, and this allows the GUI (Graphical User Interface) to be moved.
