Description

Method for controlling cursor on display screen by touchpad

technical field

The invention relates to a touch panel, in particular to a method for controlling a cursor on a display screen by the touch panel.

Background technique

The touchpad is an input device for objects such as fingers or stylus to slide or touch on it. One of its applications is to generate signals to control the cursor on the display screen to move relative coordinates or absolute coordinates. It can also support other Extensible functions, such as emulating keys. Due to great advances in monitor and display chip technology, computer systems and even home multimedia systems can support high-resolution display options, but touchpads are limited in their physical size and cannot provide such a high resolution. In order to provide a more convenient use environment, the intelligent edge function has been developed to control the automatic movement of the cursor or automatic scrolling of the page when the object slides to the edge area of the touchpad. For example, US Patent No. 5880411 sends an automatic movement signal corresponding to a fixed direction of the edge area to control the movement of the cursor when the object slides to the edge area of the touch panel. However, this method can only generate automatic movement signals in four preset directions of up, down, left, and right, and lacks design flexibility.

Therefore, there are above-mentioned inconveniences and problems in the known method for controlling cursor movement.

Detailed ways

The present invention will be further described below in conjunction with embodiment and accompanying drawing.

Please refer to FIG. 1 to FIG. 3 , FIG. 1 is a flowchart of a method according to the present invention, and FIG. 3 is a flowchart of another embodiment of FIG. 2 . As shown in the figure, the touch panel 10 has a two-dimensional sensor for sensing the position of the object 12 and is defined with a first sensing area 14 and a second sensing area 16 , which are known technologies. In this embodiment, the first sensing area 14 is an inner area on the touch panel 10 , and the second sensing area 16 is a peripheral area on the touch panel 10 . Referring to FIG. 1 and FIG. 2 , when the object 12 is on the touch panel 10 , step S1 detects the position of the object 12 , which is the same as a general touch panel. When the position of the object 12 is in the first sensing area 14, the touch panel 10 will perform a general cursor function; when the object 12 moves in the first sensing area 14, the touch panel 10 detects the position of the object 12 and generates a position signal, so The position signal can be absolute coordinates, relative coordinates or other digital signals. At this time, the cursor 20 on the display screen will move correspondingly with the movement of the object 12, and these are all known technologies. According to the method of the present invention, step S2 detects whether the object 12 enters the second sensing area 16 from the first sensing area 14, if so, calculates and records the moving direction of the object 12 when entering the second sensing area 16 from the first sensing area 14, such as As indicated by the arrow 18 in FIG. 2 , step S3 triggers an automatic movement signal controlling the cursor 20 , and its direction 22 is the movement direction 18 when the object 12 enters the second sensing area 16 . The automatic movement signal will control the cursor 20 to continue moving toward the original moving direction 18 of the object 12 . As long as the object 12 is still in the second sensing area 16 , no matter whether the object 12 is still or not, the cursor 20 will always move towards the direction 22 in response to the automatic movement signal. In some embodiments, step S4 is further included. When the object 12 enters the second sensing area 16, the displacement per unit time is also calculated and recorded, embedded in the automatic movement signal, and this information can be used to control The speed at which the cursor 20 moves.

Fig. 3 is another embodiment flowchart of Fig. 2, when step S2 detects that object 12 enters second sensing area 16 from first sensing area 14, first monitors the duration of object 12 in second sensing area 16 in step S5 , and wait until step S6 confirms that the duration is greater than the default value, and then enter step S3 to trigger the automatic movement signal.

FIG. 4 is a flowchart of another embodiment, and FIG. 5 is a schematic diagram of using the method on the touch panel 10 . The flow process of steps S1 to S3 can be the same as in Fig. 1 by step S1 to step S2 directly to step S3 or the same as Fig. 3 by step S1 to step S2, then to step S5, step S6 and then to step S3. After the automatic movement signal is triggered in step S3, step S7 detects whether the object 12 moves in the second sensing area 16, if so, calculates and records the direction in which the object 12 moves in the second sensing area 16, as shown by the arrow 24 in Figure 5, Then change the direction of the automatic moving signal to the moving direction 24 of the object 12 in the second sensing area 16 , as shown by the arrow 26 in FIG. 5 . Then the cursor 20 will follow the moving direction of the object 12 in the second sensing area 16 and move automatically. If the object 16 stops, the cursor 20 will continue to move along the current direction; if the object 12 changes direction, the cursor 20 will change to the object 12. The direction of movement continues to move. In some embodiments, step S9 is further included, and the displacement per unit time of the object 12 in the second sensing area 16 is also calculated and recorded, embedded in the automatic movement signal, and this information can be used to control the cursor 20, if the object 12 stops, the cursor 20 maintains the current moving speed; if the object 12 changes the moving speed, the cursor 20 changes its moving speed accordingly.

FIG. 6 is a flow chart of another embodiment of FIG. 5. When step S7 detects that the object 12 is moving in the second sensing area 16, calculate and record the moving direction of the object 12 in the second sensing area 16, and step S10 stops the automatic movement signal. And trigger the automatic scrolling signal of the control page, and its direction is the direction in which the object 12 moves in the second sensing area 16 . In some embodiments, step S11 is further included, and the displacement per unit time of the object 12 in the second sensing area 16 is also calculated and recorded, embedded in the automatic scrolling signal, and this information can be used to control For the scrolling speed of the page, if the object 12 stops, the page will stop scrolling; if the object 12 changes the moving speed, the scrolling speed of the page will also change accordingly.

FIG. 7 is a flowchart of another embodiment, and FIG. 8 shows the actions of the cursor 20 when using the method. Steps S1 to S7 are the same as the embodiment of Fig. 4 and Fig. 6, after step S7 detects that the object 12 moves in the second sensing area 16, the direction of the automatic movement signal is changed to enter the second sensing area 16 by the object 12 The moving direction 22 and the moving direction 26 of the object 12 in the second sensing area 16 are jointly defined, as shown by the arrow 28 in FIG. 8 .

In the above-mentioned embodiments, when the object 12 leaves the second sensing area 16, the touch panel 10 stops the automatic moving signal or the automatic scrolling signal, or continues the automatic moving signal or the automatic scrolling signal until the object 12 is detected The automatic moving signal or the automatic scrolling signal is stopped only when the sensing area 14 moves.
