Abstract

PURPOSE: A computer mouse for inputting a coordinates value using an angle change depending on inclination is provided to reduce a damage generated when a user uses a physical force for moving the mouse in an ill-balanced pose for a long time by completely transmitting a signal generated from a contact of a ball or optical mouse. CONSTITUTION: An angle signal(3) generated from an angle sensor generates an analog or digital signal(1,2) depending on an angle sensor. Noises of the generated angle signal are removed by using high/low pass filters. The signal(4) passing the filters is amplified by passing an amplifier. The amplified signal(5) is converted into the digital signal(6) through an ADC(Analog Digital Converter). The digital signal(8) is transmitted to a computer through a processor.

Description

Coordinates value input computer mouse using variable angle value for slope degree}

The present invention relates to a mouse for a coordinate value input computer using an angle change in accordance with an inclination.

The prior art will be described with reference to the drawings.

1 shows a detailed interior of a ball mouse that is currently most widely used for a computer mouse. A ball for the direction and movement of the mouse point; A roller moving in the X- and Y-axis directions by the rotation of the ball; A slot wheel connected to the roller and having a hole for transmitting light of the LED at regular intervals; Consists of LED and phototransistor receiving light.

2 illustrates a relationship between an LED, a phototransistor, and a slot wheel. The light emitted from the LED reaches the phototransistor through the hole of the slot wheel. At this time, the rollers of the X-axis and the Y-axis move together by the movement of the mouse ball, and the slot wheel connected to the rollers also depends on the direction. Will move. The direction of the mouse point changes left and right, depending on which side of the two-pair phototransistor the light that passes through the hole in the slot wheel first transmits and transmits.

However, if there is an impurity on the ball of the ball mouse or the rollers of the X-axis and the Y-axis, or the impurity is in the hole of the slot wheel through which the light of the LED passes, an error occurs in the mouse point to which the user tries to accurately position.

In addition, the optical mouse is the same as the ball mouse in that it transmits / receives the light of the LED, but the LED transmitting part and the receiving part are separated independently by maintaining a certain angle. You can see the mouse's direction and distance. Optical mouse uses the reflection of light, so if the reflecting surface, that is, the bottom surface of the mouse is made of transparent glass, or if the reflecting surface is irregular and bumpy, the reflected light may not be transmitted to the receiver properly, or the light may be refracted. This will cause an error at the mouse point.

In addition, the mouse described as an example, since most users sit in a chair and place one arm on a mouse on a desk and operate, an unbalanced posture that is not normally felt may continue, causing stress on the wrist, arm, and waist.

An object of the present invention is to imbalance the physical force for moving a mouse without generating an incomplete signal transmission by contact such as a ball mouse or an optical mouse to supplement and develop a pointing device such as a mouse having the above disadvantages. It is a computer mouse to input the coordinate value using the change of angle according to the inclination of the user by moving the mouse in space.

Hereinafter, a preferred embodiment of a mouse for a coordinate value input computer using an angle change according to the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited or limited by the following examples.

Figure 3 shows the tilt angle of the X-axis and Y-axis when tilting the angle sensor 10 to be attached to the inside of the computer mouse of the present invention. The inclination of the angle sensor 10 is inclined by -15 ° (11) and the inclination of 15 ° (12) with respect to the X axis (Y-axis 0 ° degree FIXED), and the angle sensor 10 The slope of X-axis is tilted by -15 ° (13) and 15 ° (14) inclined with respect to the Y axis (X-axis 0 ° degree FIXED).

Figure 4 shows a functional block diagram and a flow chart inside the computer mouse of the present invention. The angle signal ③ generated by the angle sensor generates an analog (①) or digital signal (②) depending on the angle sensor. An angle sensor that generates an angle signal will be described later. If the angle sensor for generating an analog signal is described, the generated angle signal is generated with a large amount of noise by the user's operation (③). At this time, the noise passes through the HIGH PASS FILTER / LOW PASS FILTER to generate only the required signal (④). Since the signal passing through the filter is small in size, the signal is made large by the amplification part so that the processor can recognize it. The amplified signal becomes a digital signal (⑥) through the AD converter when its value is analog. The digital signal is transmitted to the computer via a processor that calculates the value. In addition, the signal (⑦) of the button attached to the mouse is transmitted to the computer via the processor. The angle sensor for generating the digital signal transmits the angle signal ③ directly to the processor.

FIG. 5 shows a circuit diagram when GYROSCOPE of MURADA is used as an example of a component for generating an analog angle signal among the angle sensors described in FIG. 4. The signal generated through ENC-03J passes through the filter part consisting of HIGH PASS FILTER and LOW PASS FILTER, and then the final signal is generated through the amplifier stage NJM2115. This signal, though not shown in the schematic, is connected to the processor via an AD conversion section that must be added.

FIG. 6 illustrates an angle sensor 30 that generates a digital angle signal among the angle sensors described in FIG. 4. The angle sensor 30 moves the ball inside the angle sensor 30 by the user's operation, and the ball moves to the left 31 or right 33 according to the inclined direction and opens a hole passing through the LED light. It will hide the signal of the phototransistor. The processor can measure the moving distance by triggering a timer interrupt from the moment the signal of the phototransistor changes. The closer the distance d between the phototransistors 1 and 2 is, the shorter the distance the ball travels, making it easier to move even with angle changes with less mouse point changes.

Coordinate Value Input Using the Angle Change According to the Incline of the Present Invention As described above, since a computer mouse is used conveniently when moving, there is no need for severe arm movement and no two-dimensional space is required. If you do this, the person in charge can operate the computer, etc. can be a great effect.
