KR20010011148A - Right button implementation method for touch pad - Google Patents

Abstract

PURPOSE: A method for implementing touch pad's right button is provided to prevent erred operations caused by the embodiment and the touch of a touch pad's right button by supplying a pointer maneuver button, a left button, and a right button functions on the touch pad areas where the contact between the pad and the fingers is made and acknowledging the mouse button commands only when the left or the right button is pressed with the pointer maneuver button. CONSTITUTION: A pointer maneuver touch point and a button click touch point are distinguished in order to solely maneuver a pointer when a single touch point is pressed and to acknowledge the right button click when a second finger contact point is made on an X-axis coordinate point that is greater than the first finger X-axis contact point. If the second finger contact point is made on a smaller X-axis coordinate point than the first finger X-axis contact point, the left button click is acknowledged.

Description

How to implement the right button on the touchpad {RIGHT BUTTON IMPLEMENTATION METHOD FOR TOUCH PAD}

The present invention relates to a method for implementing the right button of a touch pad, and in particular, in a notebook computer or the like, the pad can be replaced without pressing the right button directly on the touch pad, which facilitates the carrying of the computer by replacing the mouse with a finger. The present invention relates to a method for implementing a right button on a touch pad, which makes it easier to use the touch pad by easily implementing the right button on the screen.

In general, the touchpad can be easily seen in a notebook computer as shown in FIG. 1, and replaces the role of a mouse. In this operation, once the finger is placed on the pad and moved lightly, the mouse pointer on the screen moves. Will be moved in the direction.

Therefore, in the case of a mouse, when selecting a menu or data by moving like this, the left button is clicked or double-clicked. In the touch pad, the finger on the pad is pressed or touched once or twice. By pressing the left button of the two buttons located above or below the pad, it is judged as a click like the left button of a mouse.

In addition, the right button of the mouse is used to request registration information such as a background or a menu where the mouse pointer is located, and the touch pad does not produce a right button effect by tapping the pad surface like the left button. Only by pressing the right button between the two buttons located above or below the touchpad, it acts like the right button on the mouse.

As such, in the conventional technology, the right button is not implemented by tapping the touch pad, unlike the left button. Instead, the right button is pressed directly, and due to the sensitive sensitivity of the pad, the touch button slightly rubs on the pad during operation. There was a problem in that it was inconvenient to use because it was mistaken as being clicked.

Therefore, the present invention has been created to solve the above-mentioned conventional problems, by assigning the role of the pointer move button, the left button, and the right button, respectively, by the number and position of the fingers in contact with the touch pad, together with the move button. It is an object of the present invention to provide a method for implementing a right button of a touch pad in which the right button on the pad is prevented from malfunctioning due to the implementation of the right button on the pad.

1 is an exemplary view of a notebook computer with a touchpad attached.

Figure 2 is an exemplary view showing a touchpad using method according to the present invention.

Figure 3 is a flow chart illustrating a process of determining a button click according to the present invention.

The present invention for achieving the above object, the first step of detecting whether there is a touch pad; A second step of determining a contact point as a first contact point for moving the pointer when there is a contact; A third step of detecting whether there is another second contact point in addition to the first contact point; And a fourth step of determining whether the right or left button is clicked by comparing whether the x coordinate of the second contact point is larger or smaller than the first contact point.

Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

First, the mouse pointer reads the x and y coordinates of the first touched part of the touch pad and recognizes it as the coordinate where the current pointer is located, and moves the pointer as the coordinate value changes as the contact point on the pad moves.

In this case, for example, the index finger is moved to the pad immediately when the user moves the pointer using the index finger and then clicks the left button. However, in the present invention, as shown in FIG. If you want to click the left button when you use your right hand, tap your index finger on the pad with your middle finger touching on the pad. If you want to click the right button, you tap your finger on the pad.

At this time, if the x-coordinate of the second contact point where the index finger is touched is larger than the reference point, the right button is clicked. If it is smaller than the reference point, the left button is clicked. do.

In other words, in the prior art, the mouse pointer was moved to an arbitrary position on the screen, the finger was removed from the pad surface, and then the pad was recognized as a click. However, in the present invention, the finger moving the pointer is in contact with the pad surface. You only have to hit the pad with another finger to recognize it as a click.

Accordingly, the present invention distinguishes the contact point for the pointer movement and the contact point for the button click, as shown in the flowchart shown in FIG. 3, when there is only one contact point, only the pointer is moved, and the other contact is maintained while maintaining the moved contact. In this case, when the x-coordinate value of the second contact point is larger than the x-coordinate value of the first contact point, the right button is recognized as clicked, and when it is small, the left button is recognized as clicked.

As described above, the right button implementation method of the touch pad according to the present invention implements both the right button and the left button on the pad surface without directly pressing the actual button, and the finger moved by the pointer must be in contact with the pad surface, and another contact occurs. In this case, it is easy to use by only recognizing a click, and there is an effect of preventing any contact from being mistakenly recognized as a click.

Claims (3)

A first step of detecting whether a touch pad is in contact; A second step of determining a contact point as a first contact point for moving the pointer when there is a contact; A third step of detecting whether there is another second contact point in addition to the first contact point; And a fourth step of determining whether the right or left button is clicked by comparing whether the x coordinate of the second contact point is larger or smaller than the first contact point. The method of claim 1, wherein the right button is determined to be clicked when the x coordinate value of the second contact point is larger than the x coordinate value of the first contact point. The method of claim 1, wherein when the x coordinate value of the second contact point is smaller than the x coordinate value of the first contact point, it is determined that the left button is clicked.
