Abstract

The invention provides a computer cursor control system and a method for controlling cursor movement, wherein the computer cursor control system comprises a touch pad device and a cursor control program. The cursor control program displays a virtual pointer on the computer screen according to the touch of the finger on the touch pad device, so that a user can clearly know the position relation between the position of the touch pad and the end point position; the virtual pointer and the computer cursor are simultaneously moved according to the movement of the finger on the touch pad, so that the virtual pointer can be quickly moved to the end point position only by small finger movement; and finally, moving the computer cursor to the position of the virtual pointer according to a switch signal (for example, directly pressing the touch pad) generated by the touch pad device. The invention solves the defects that the known relative coordinate method needs to move on the touch pad for many times and the absolute coordinate method cannot accurately align the position of the screen.

Description

Computer cursor control system and method for controlling cursor movement

technical field

The invention relates to a cursor control system, in particular to a computer cursor control system and a cursor control method for rapidly moving the cursor by providing a virtual pointer.

Background technique

A touchpad device (touchpad device) is often set on a notebook computer to control the movement of a cursor. The user moves the finger on the panel to make the cursor move correspondingly on the computer screen.

There are two methods of controlling the movement of the cursor in the conventional touch panel device, one is to move the cursor according to relative coordinate data, and the other is to move the cursor according to absolute coordinate data.

The so-called method of controlling the movement of the cursor based on the relative coordinate data is the same as the known method of controlling the movement of the cursor by moving the mouse on the desktop. That is, the moving distance and direction of the cursor are determined according to the moving direction of the finger on the touchpad and the accumulated moving distance. Most of the users are not very used to the operation mode of the relative coordinate touch panel device, the reason is that the area of the touch panel is not large, so if the cursor is to move a larger displacement, it is necessary to place the finger on the touch panel several times. Move to accumulate the desired cursor displacement.

In order to solve the disadvantages of the relative coordinate touch panel device, it is known to propose an absolute coordinate touch panel device. The absolute coordinate touch panel device moves the cursor to the corresponding coordinate position on the screen according to the coordinate position of the user on the panel, so the user can move the cursor to the desired position without sliding the finger.

However, since the area of the touchpad is much smaller than the area of the screen, the coordinates touched by the user on the touchpad usually cannot be precisely aligned with the originally intended cursor position on the screen. When a fine cursor position needs to be moved, The touch device of absolute coordinates is not convenient to use.

Therefore, there is a need for an improved cursor movement control method for a touch panel.

The main purpose of the present invention is to provide a computer cursor control system and a cursor control method for rapidly moving the cursor.

The present invention provides a computer cursor control system for controlling the movement of a computer cursor on a computer screen. The computer screen is connected to a host computer. The system includes:

A touch panel device, electrically connected to the host, including a touch panel, a left button and a right button, for generating a relative displacement signal according to the movement of the finger on the touch panel, and responding to the operation of the finger on the panel and generate a switch signal;

A cursor control program is set in the host computer to perform the following steps:

displaying a virtual pointer on the screen corresponding to a contact position of the finger on the touch panel;

simultaneously moving the computer cursor and the virtual pointer displayed on the screen according to the relative displacement signal;

After receiving the switch signal, the computer cursor is moved to the position of the virtual pointer.

In an embodiment of the invention, the switch signal is generated when the touchpad moves downward.

The present invention also provides a method for controlling the movement of a cursor, for controlling the movement of a cursor on a screen, wherein the movement of the cursor depends on the movement of a finger on an input device, the method comprising:

displaying a virtual pointer on the screen at a contact position corresponding to the contact position of the finger on the input device;

simultaneously moving the cursor and the virtual pointer in accordance with the movement of the finger on the input device; and

The cursor is moved to the position of the virtual pointer in response to a switch signal.

By displaying the virtual pointer on the screen, the user can clearly know the positional relationship between the touched touchpad position and the end position, so only a small finger movement can quickly move the virtual pointer to the end position, and By directly pressing down on the touchpad to move the cursor to the position of the virtual pointer, the present invention solves the known disadvantages that the relative coordinates need to be moved on the touchpad multiple times and the absolute coordinates cannot be accurately aligned with the screen position.

Detailed ways

Please refer to FIG. 1 , which is a schematic diagram of a computer cursor control system of the present invention applied to a notebook computer. FIG. 1 shows a computer screen 10 , a host 20 , and a touchpad device 40 . The touchpad device 40 includes a touchpad 41 , a left button 42 and a right button 43 . The functions of the left button 42 and the right button 43 are the same as those of the known mouse. And there is a computer cursor R on the computer screen 10 .

The computer cursor R can be moved by moving the finger on the touchpad 41 , and the greater the accumulative moving distance of the finger on the touchpad 41 , the greater the distance that the computer cursor R is moved. The computer cursor control system of the present invention includes a cursor control program 30 set in the host computer 20 . The cursor control method of the present invention is executed by starting the cursor control program 30 .

Please refer to FIG. 2A to FIG. 2D , which are schematic diagrams of the movement of the computer cursor R of the computer cursor control system of the present invention. As shown in FIG. 2A , the computer cursor R is originally located at a position P1 on the screen 10 and is scheduled to be moved to an end position PT. According to the known moving method of relative coordinates, the cursor R must be moved from the position P1 to the position PT by repeatedly moving the finger back and forth on the touch panel 41 several times. If the known absolute coordinate method is used, then the cursor R must be touched and pressed with a finger on the corresponding position PT on the touch panel 41 (for example, point A1). However, since the computer screen 10 and The area of the touchpad 41 varies greatly, so the position of the point A1 is generally difficult to accurately correspond to the position PT of the screen 10 .

The cursor moving method of the present invention will be described below according to FIG. 2B to FIG. 2D . As shown in FIG. 2B , the user first touches a point on the touch panel 41 approximately corresponding to the end position PT, such as point A1 . At this time, the cursor control program 30 will display a virtual pointer VR on the screen 10, and then move the finger on the touch pad 41 toward the direction of the end point coordinate PT. At this time, the cursor R and the virtual pointer VR will be moved simultaneously according to the displacement signal generated by the finger moving on the touch panel 41 . As shown in FIG. 2C , when the finger moves from position A1 to A2 , the cursor moves from position P1 to position P2 , and the virtual pointer is moved to the end position PT. Please refer to FIG. 2D , when the virtual pointer VR is moved to the end position PT, press the touchpad 41 with a finger to move the entire touchpad 41 downwards to generate a switch signal. When the cursor control program 30 receives the switch signal, Then the cursor R is moved to the terminal position PT where the virtual pointer VR is located. The structure of the touchpad device 40 that moves the touchpad 41 downward to generate a switch signal is well known, so it will not be repeated in this specification. For example, China Taiwan No. 470193 New Bulletin "A Touch Pad Device for Digital Electronic Products" discloses a touch pad device that can generate switching signals by moving the touch pad downward.

Since the present invention displays the virtual pointer VR on the screen, the user can clearly know the positional relationship between the position of the finger on the touchpad 41 and the end position PT on the screen, and can move the virtual pointer VR clearly and quickly. to the end position PT. Then, as long as the touchpad is pressed down to generate a switch signal, the cursor R can be moved to the end position PT immediately, without repeatedly moving the finger on the touchpad 41 .

Please refer to FIG. 3 , which is a flow chart of the cursor control program 30 controlling the movement of the cursor R according to the present invention.

Step 300: start;

Step 400: Display a virtual pointer VR on the screen 10 according to the position of the finger on the touchpad 41;

Step 500: Simultaneously move the virtual pointer and the cursor according to the movement of the finger;

Step 600: Is the touch panel 41 pressed down to generate a switch signal? If so, go to step 700, otherwise go back to step 500;

Step 700: move the cursor to the position of the virtual pointer;

Step 800: end.

According to the above description, it can be understood that the cursor control system of the present invention allows the user to clearly know the positional relationship between the position of the touched touchpad and the end position by displaying a virtual pointer on the screen. The virtual pointer can be quickly moved to the end position, and the cursor can be immediately moved to the position where the virtual pointer is located, that is, the end position, by directly pressing down on the touch panel. It solves the shortcomings of the known relative coordinates that need to be moved on the touchpad multiple times and that the absolute coordinates cannot be accurately aligned with the screen position.

Various modifications can be made to the present invention by those skilled in the art without departing from the protection scope of the appended claims.
