Problems solved by technology

[0003] At present, the method for realizing the long-distance movement or automatic movement of the cursor on the touch panel is usually to set a relatively large cursor movement rate factor; Mentioned in: When the finger moves to the edge of the touchpad, stopping the finger can realize the continuous movement of the cursor, but when the edge scrolling function is set, these two operations are likely to cause conflicts
Another example is the patent No. 200510082859.2 "Control method for smart movement of touchpad" mentioned: After the finger moves, after a pause for a time interval, the cursor can continue to move along the original direction, but this may cause misoperation , because the user sometimes pauses naturally when moving the cursor, and once a certain period of time passes, the cursor will continue to move, which is not the user's original intention

Embodiment 1

[0022] As shown in Figure 1, a method for realizing automatic cursor movement on a touch panel includes providing a touch panel, detecting the number of fingers on the touch panel and starting the automatic cursor movement function, wherein starting the automatic cursor movement function includes the following steps:

[0023] First, enter the cursor automatic movement mode; then, detect that the first finger touches the touchpad; detect that the first finger is moving on the touchpad, and send the position information of the first finger to the host, and the host according to the first finger The position information of a finger controls the movement of the cursor; it is detected that the first finger stops moving, and the first finger does not leave the touchpad, then sends a cursor stop moving signal to the host, and the cursor stops moving; secondly, within the first preset time interval Detecting that the second finger touches the touchpad, and the second finger does not le...

Embodiment 2

[0027] A method for realizing automatic cursor movement on a touch panel, wherein when the cursor automatic movement function is activated, the cursor movement direction is that the first finger moves from the first touch point P1 to the second touch point P2. The tangent direction of the second touch point P2 is that the first touch point P1 points to the second touch point P2. As shown in Figure 2, the first finger moves along a straight line from the first touch point P1 to the second touch point P2, the automatic movement direction of the cursor is the direction in which the first touch point P1 points to the second touch point P2, and the cursor will move along the This direction moves automatically.

Embodiment 3

[0029] A method for realizing automatic cursor movement on a touch panel, wherein when the cursor automatic movement function is activated, the cursor movement direction is that the first finger moves from the first touch point P1 to the second touch point P2. The tangent direction of the second touch point P2 is that the first touch point P1 points to the second touch point P2.

[0030] As shown in Figure 3, the first finger moves along the curve from the first touch point P1 to the second touch point P2, and the automatic movement direction of the cursor is the tangent direction of the cursor movement track curve at the second touch point P2, pointing to the first The touch point P1 points to the direction of the second touch point P2, and the cursor will automatically move along this direction.

Abstract

A method for realizing the automatic movement of a cursor on a touch-control board comprises the step of providing the touch-control board, and is characterized in that the method further comprises the step of starting the automatic moving function of the cursor. The step of starting the automatic moving function of the cursor comprises the following procedures: entering the automatic moving modeof the cursor; detecting that a first touch object touches the touch-control board; detecting that the first touch object moves on the touch-control board, sending out the position information of thefirst touch object to a host computer, and controlling the movement of the cursor according to the position information of the first touch object; detecting that the first touch object stops moving and does not depart from the touch-control board, sending out a signal of stopping movement of the cursor to the host computer, and then stopping the movement of the cursor; detecting that a second touch object touches the touch-control board at first preset time intervals and does not depart from the touch-control board; sending out a signal of automatic movement of the cursor to the host computer; and determining the automatic moving direction of the cursor and controlling the automatic movement of the cursor through the host computer according to the position information of the first touch object. The invention can realize the automatic movement of the cursor through detecting the change of the number of the touch objects.

Description

technical field [0001] The invention relates to a method for controlling cursor movement, in particular to a method for realizing automatic cursor movement on a touch panel. Background technique [0002] Nowadays, touch panels have been widely used in electronic devices such as personal digital processing (PDA), mobile phones, handheld computers, and tablet computers. The touchpad is an input device for the user to slide or touch on the panel with a hand or a conductive object (such as a stylus), which can make the cursor move relative to each other and support other extended functions. [0003] At present, the method for realizing the long-distance movement or automatic movement of the cursor on the touch panel is usually to set a relatively large cursor movement rate factor; It is mentioned in: When the finger moves to the edge of the touchpad, the finger stops to realize the continuous movement of the cursor, but when the edge scrolling function is set, these two operati...
