Abstract

The present invention discloses a method for accelerating cursor movement by sliding two fingers on a touch panel, which includes the following steps: if two fingers are detected to contact the touch panel, and the two fingers slide in the same direction within a set initial period of time, and the distance Dx (X1t-X2t) in the X direction and the distance Dy (Y1t-Y2t) in the Y direction between the two fingers are always kept within a spacing tolerance d, the touch panel software switches to a cursor acceleration mode, and accelerates the cursor movement according to a set multiple; if it is judged to be a single-finger slide within the set initial contact time, the cursor is moved at a set normal speed. The present invention can change the cursor speed in a simple way, as long as the two fingertips slide to maintain a rough distance, without paying special attention to the gestures, or even moving the palms significantly, and does not require a long learning period to flexibly master, which is very convenient.

Description

How to accelerate cursor movement by sliding two fingers on the touchpad

Technical field:

The invention relates to the technical field of touch panels, in particular to a cursor acceleration method for a touch panel.

Background technique:

The screen area of a general computer is much larger than the area of the touchpad, and the sliding speed of the cursor on the screen depends on the setting speed of the control panel and the movement speed of the finger. However, the general design is that when the finger slides across the horizontal length of the touchpad, the cursor moves half the horizontal length on the screen, because it is easy to miss the target if it is too fast, and it is inconvenient to call back and correct it; Tired easily.

People in the industry have developed two methods to operate the cursor at two speeds. One is to determine the speed of the cursor by the contact area of the finger. If the fingertip touches lightly, it will slide at a slow speed, and if it touches a large area with force, it will slide quickly. The disadvantage of this method is that it is difficult to define the size boundary of the finger because each person's fingers are different. Although it can be set individually according to each person, in actual operation, if the finger is to be in contact with a large area, the entire Fingers do not bend, and touch the touchpad with a small angle with the horizontal plane. In addition, the palm needs to be displaced relatively large, and the operation is quite inflexible, so this method is generally seldom used. Another way to operate the cursor at two speeds is to use the different sliding speeds of the fingers on the touchpad to move the cursor at different speeds. This method is easy to operate and does not have the inflexibility of the first method; The disadvantage of this method is that it is difficult to judge the moving speed and sliding distance, and the user needs to learn for a period of time, otherwise it is difficult to master, so it is rarely used.

Invention content:

The object of the present invention is to provide a method for accelerating cursor movement by sliding with two fingers on a touch panel, which has the characteristics of simple operation and flexible control.

In order to achieve the above object, the method for accelerating the movement of the cursor by sliding two fingers on the touch panel of the present invention includes the following steps: If both the distance Dx (X1t-X2t) in the X direction and the distance Dy (Y1t-Y2t) in the Y direction between the two fingers are kept within a distance tolerance d, then the touchpad software switches to the cursor acceleration mode, according to the setting The multiple of the cursor accelerates; if it is judged to be a single-finger slide within the set initial contact time, the cursor will move at the set normal speed.

As the preference of the above-mentioned technical scheme. The touch pad is a touch pad applied to a keyboard of a notebook or a desktop computer, or a remote control of a closed-circuit television, and the touch pad supports a multi-finger touch mode.

As a preferred option of the above technical solution, the computer is equipped with an operation interface, which can change the acceleration multiple of two fingers sliding in the same direction. After the user sets it, the computer system sends a signal to the touch panel to change the set value.

As a preferred option of the above technical solution, the computer is equipped with an operation interface, which can change the tolerance of the distance between the two fingers. After the user sets it, the computer system sends a signal to the touch panel to change the set value.

The beneficial effect of the present invention is that it can change the speed of the cursor in a simple way, as long as the two fingertips can be easily slid to maintain a rough distance, no need to pay special attention to gestures, or even move the palm substantially, without going through a long period of time. The study period can be flexibly mastered, which is very convenient.

Description of drawings:

Below in conjunction with accompanying drawing, the present invention will be further described:

Fig. 1 is a flowchart of the present invention.

Detailed ways:

The following descriptions are only preferred embodiments embodying the principles of the present invention, and do not therefore limit the protection scope of the present invention.

As shown in Figure 1: the finger touches the touchpad, does not move first, and first judges whether it is a single finger or two fingers; at the same time, judge the finger movement state in the initial period of time, and the method is to detect every other time Segmentally detect the positions (X1, Y1) and (X2, Y2) of two fingers, and calculate the X-direction distance Dx(X1t-X2t) and Y-direction distance Dy(Y1t-Y2t) between the two fingers. If the X-direction distance Dx(X1t-X2t) and the Y-direction distance Dy(Y1t-Y2t) are kept within a distance tolerance d, it is judged that the finger slides in the same direction, and the touchpad software switches to the cursor acceleration mode. A fixed multiple (1.2 to 3 times) moves the cursor at multiple times.

If it is judged as one-finger sliding within the set initial contact time, move the cursor at the set normal speed; if the X-direction distance Dx and Y-direction distance Dy between the two fingers is greater than the tolerance d and gradually changes, enter other In the multi-finger control mode, if two fingers touch and leave without displacement, the command will be issued according to the dwell time of the finger contact and the position of the two fingers. Leave the finger to return to the initial state.

The method for determining the multiplier of the cursor speed is: set an operation interface on the computer to change the acceleration multiplier when two fingers slide in the same direction. After the user sets it, the computer system sends a signal to the touch panel to change the set value. In addition, the operation interface can also change the tolerance of the distance between two fingers. After the user sets it, the computer system sends a signal to the touch panel to change the set value.
