Wherein, the electronic device 100 includes a personal computer and a portable device such as a mobile internet device (Mobile Internet Device, MID), a notebook computer or a mini notebook computer (Netbook), etc., but is not limited thereto. The electronic device 100 according to the embodiment of the present invention at least includes a touchpad 110 , a simulation device 120 , a processor 125 and at least one application program 140 . The touchpad 110 can be used to receive a user input. The user can input data by operating the touch panel 110 . In this embodiment, the touch panel 110 is combined with a touch sensing device 112 . The touch sensing device 112 has a touch surface including at least one-dimensional sensors for detecting contact and movement of an input tool, such as a finger or a stylus, on its surface, which allows the user to use an input tool such as a finger or stylus for single-point or multi-touch input. The processor 125 also includes an operating system 130 . A virtual device generated by the simulation device 120 when the touchpad 110 is activated is mainly used to enable the touchpad 110 to transmit touch information to the operating system 130 in a specific use mode, and then use the touchpad 110 to simulate touching behavior. The processor 125 is coupled to the touch panel 110 and the simulation device 120, and is used for performing mouse input simulation through the operating system 130 according to a mouse signal from the touch panel 110 or through the operating system 130 according to a touch signal from the simulation device 120.

For example, when the operating system 130 performs mouse simulation, the operating system 130 regards the input of the touchpad 110 as mouse input; Touch input for the touch panel. The operating system 130 can be a Windows operating system that supports multi-touch, such as Window 7, Window 8, etc. of Microsoft(TM). The application program 140 can receive a touch signal or a mouse input signal from the Windows operating system 130, and perform subsequent operations according to the received information.

The electronic device 100 can be used to execute the control method of the present application, the details of which will be described later.

FIG. 2 shows a flow chart of a method for controlling an electronic device according to an embodiment of the invention. Please refer to Figure 1 and Figure 2 at the same time. The electronic device control method according to the embodiment of the present invention can be applied to the electronic device 100 to determine whether the detected touch event is a mouse input or a touch input.

First, in step S202, the touch panel 110 detects a touch event. Next, in step S204, the touch panel 110 determines whether the touch event is a multi-touch event. Specifically, the touch sensing device 112 of the touch panel 110 can determine whether the touch event is a single-point touch event generated by a single finger or two fingers by detecting the number of touch points corresponding to the touch event. Multi-touch events generated by the above fingers. When it is detected that the touch event corresponds to two or more touch points, it is determined that the touch event is a multi-touch event. On the contrary, when it is detected that the touch event only corresponds to one touch point, it is determined that the touch event is a single-point touch event.

When the touch event is a single-point touch event (No in step S204), it means that the user wants to perform mouse simulation. As in step S208, the touch panel 110 generates a mouse input signal to the operating system 130, causing the operating system 130 to perform mouse simulation. Mouse emulation. Thus, the operating system 130 will treat the touch event as a normal mouse input.

Conversely, when the touch event is a multi-touch event (Yes in step S204), it means that the user wants to perform touch simulation. As in step S206, the touch panel 110 simulates the touch event through the simulation device 120 as A first event of a touch panel generates a multi-touch signal to the operating system 130, causing the operating system 130 to perform a corresponding touch simulation. Therefore, the operating system 130 regards the touch event as a general touch input on the touch panel. Therefore, the touchpad 110 can simultaneously provide functions of mouse input and touch input of the touch panel.

In this embodiment, the touch sensing device 112 of the touch panel 110 can further judge various touch operations of the simulated touch panel when it detects that the multi-touch event corresponds to two touch points, and can Correctly distinguish these touch operations. For example, the touch operation simulated by the multi-touch event at least includes a tap (Tap) operation, a translation (Pan) operation, a zoom (Zoom) operation, and a rotation (Rotate) operation, etc., but not limited to this.

FIG. 3 shows a flowchart of a control method according to another embodiment of the present invention. Please refer to Figure 1 and Figure 3 at the same time. The control method according to the embodiment of the present invention can be applied to the electronic device 100 to further determine the touch operation simulated by the touch event when the two-point touch input is detected.

First, when the touchpad 110 detects one or two touch events, that is, when a multi-touch event corresponds to two touch points, the touchpad 110 detects the positional relationship between the two touch points and a movement behavior (step S302) . Wherein, the touch sensing device 112 of the touch panel 110 can continuously detect the position, moving distance, moving angle and other parameters of the two touch points to determine the positional relationship and moving behavior of the two touch points. Afterwards, the touch panel 110 judges which type of touch operation the touch operation simulated by the multi-touch event belongs to based on the measured/calculated positional relationship and movement behavior of the two touch points (step S304 ). For example, the touch operation simulated by the multi-touch event at least includes a click operation, a translation operation, a zoom operation, a rotation operation, etc., but is not limited thereto.

For example, in one embodiment, a possible judgment method of the touch operation is as follows. Assume that if there are two touch points input, the touchpad can collect some information changes obtained on the touchpad, where the composition of the change can be the distance between the two touch points approaching each other, the distance away from each other, The sum of the distance moved, the angle moved, etc., and each component can also have different weights. For example, the variation Var can be defined as

Var=(D1*wD1)+(D2*wD2)+(M*wM)+(A*wA)(1),

Among them, D1 represents the distance between the two touch points close to each other, wD1 represents the weight corresponding to D1; D2 represents the distance between the two touch points away from each other, wD2 represents the weight corresponding to D2; M represents the moving distance of the two touch points, wM represents : the weight corresponding to M; and A represents the moving angle of the two touch points, wA represents: the weight corresponding to A.

Afterwards, it can be determined which type of touch operation the touch operation simulated by the multi-touch event belongs to according to the variation Var. When the amount of change is greater than a certain degree, it is determined which touch behavior is determined.

When it is judged that the touch behavior is that the two touch points fall without a large amount of movement or rotation, that is, the positions of the two touch points have not changed and the two touch points have no movement behavior, determine the touch simulated by the multi-touch event. The touch operation is a tap operation, as shown in FIG. 5A . Therefore, the touchpad 110 requires the simulation device 120 to send a touch input signal representing a click to the operating system 130 according to the current mouse position.

When it is judged that the touch behavior is that the two touch points fall and move in the same direction (the direction is not limited), that is, the positions of the two touch points change along the same direction and the movement behavior is that the two touch points move along the same direction , it is determined that the touch operation simulated by the multi-touch event is a translation (Pan) operation, as shown in FIG. 5B . Therefore, the touchpad 110 converts the moving distance into the moving distance triggered by the touch translation operation, requiring the simulation device 120 to send a touch input signal representing translation to the operating system 130 according to the moving distance.

When it is determined that the touch behavior is that the two touch points fall and move in opposite directions, that is, the positions of the two touch points change in opposite directions and the movement behavior is that the two touch points move in opposite directions, it is determined that the multi-touch The touch operation simulated by the touch event is a Zoom operation, as shown in FIG. 5C . Therefore, the touchpad 110 converts the moving distance into a zoom ratio corresponding to the touch zoom operation, and requires the simulation device 120 to send a zoom touch input signal representing the zoom ratio to the operating system 130 .

When it is judged that the touch behavior is that two touch points fall and form a circular gesture, that is, the positions of the two touch points change along a clockwise or counterclockwise direction and the movement behavior is that the two touch points move along a clockwise direction. Or when moving counterclockwise, it is determined that the touch operation simulated by the multi-touch event is a Rotate operation, as shown in FIG. 5D . Therefore, the touchpad 110 requires the simulation device 120 to send a touch input signal indicating rotation to the operating system 130 . Therefore, the user only needs to operate on the touch panel 110 according to the input method on the touch panel, which is very convenient to use.

In some embodiments, the electronic device 100 of the present application can provide a predetermined application program, and the user can directly start the predetermined application program through a specific gesture on the touchpad 110, and the touchpad 110 can further determine the multi-point The touch point corresponding to the touch event, when the touch panel 110 detects that the multi-touch event corresponds to three touch points (generated by three fingers) or the multi-touch event is generated by a specific gesture, it can directly A given application is launched without going through the operating system 130 . For example, when the touchpad 110 receives some special input, such as a three-finger touch (as shown in FIG. 5E ), a specific upper-layer application program can be directly launched.

In some embodiments, the electronic device 100 of the present application may further provide a user interface for selecting/setting an operation mode of the touchpad, so that when the touchpad 110 receives a single point of a single touch point When a touch event is input, it can be further determined whether to directly transmit a mouse input signal to the operating system 130 or to convert it into a multi-touch signal through the simulation device 120 and then transmit it to the operating system 130 .

FIG. 4 shows a flowchart of a control method according to yet another embodiment of the present invention. Please refer to Figure 1 and Figure 4 at the same time. The control method according to the embodiment of the present invention can be applied to the electronic device 100 to determine the touch operation simulated by the touch event according to the operation mode of the touchpad when a single touch input is detected. In this embodiment, it is assumed that the touchpad can be operated in a first mode and a second mode through a user interface selection/setting, wherein, when the touchpad 110 operates in the second mode, the touchpad 110 Can represent touch input or mouse input.

When the touch event is a single-point touch event (step S402), the touchpad 110 determines whether it is operating in a specific mode (second mode) (step S404). If the touchpad 110 is not operating in a specific mode (that is, operating in the first mode) (No in step S404), the touchpad 110 generates a mouse signal to the operating system 130, causing the operating system 130 to perform mouse simulation (step S406 ). Thus, the operating system 130 will treat the touch event as a normal mouse input.

If the touchpad 110 is operating in a specific mode (that is, operating in the second mode) (Yes in step S404), the touchpad 110 further determines whether a touch point of the corresponding single-touch event comes from the touchpad 110. an edge (step S408). That is to say, the touchpad 110 will determine whether the single-point touch event is generated by a specific gesture (from edge gesture) sent from one of the edges, as shown in FIG. 5F . When the touch point of the corresponding single-touch event is not from any edge of the touchpad 110 (No in step S408), the touchpad 110 generates a mouse signal to the operating system 130, causing the operating system 130 to perform mouse simulation. (step S410). Thus, the operating system 130 will treat the touch event as a normal mouse input.

On the contrary, when the touch point of the corresponding single-point touch event comes from one of the edges of the touchpad 110 (Yes in step S408), the touchpad 110 simulates the single-point touch event as a touch through the simulation device 120 A second event of the panel to generate a multi-touch signal to the operating system 130 (step S412). Therefore, the operating system 130 regards the touch event as a touch input of a general touch panel.

Furthermore, generally speaking, when the user operates the touchpad 110 with two fingers, the touchpad 110 will request the simulation device 120 to input touch information to the operating system according to the position of the cursor. In some embodiments, in order to correctly simulate various touch operation behaviors of the touch panel, it may be necessary to modify/adjust the position of the input touch point with reference to the position of the cursor to cope with different situations.

In one embodiment, it is assumed that the user performs a zoom-out or zoom-in gesture with two fingers. When the user performs a zoom-out or zoom-in gesture with two fingers, assuming that the position of the cursor is close to the edge of the screen, the positions of the two touch points must fall within the range of the screen.

For example, when the cursor position is not close to the edge of the screen, a certain distance will be input between the two touch points, and when the cursor position is close to the edge of the screen, a certain distance will be taken between the two touch points Input and ensure that the position of the input touch point must fall within the range of the screen.

In another embodiment, it is assumed that the user operates a scroll gesture by moving two fingers in parallel. In this embodiment, there are two ways to achieve the scrolling effect, namely, the way of repeatedly inputting the position of the touch point and the way of inputting the positions of two touch points at one time.

For example, when the user uses two fingers to move in parallel to the left, the corresponding touch point will input the touch point according to the position of the cursor, but if the position of the touch point is about to or has moved outside the screen, Scrolling will stop. At this time, the uninterrupted scrolling effect can be achieved by repeatedly inputting the position of the touch point, returning to the starting point of the touch point and continuing to input again. If the cursor is too close to the edge, the starting position of the touch point can be moved to the center of the screen by an appropriate distance to achieve uninterrupted scrolling.

In some embodiments, since some applications allow the translation of two touch points to scroll the elements of the user interface (UI component), even if a touch point has fallen outside the screen range or has triggered a touchup (touchup) )the behavior of. So when the cursor position is close to the edge, you can enter two touch points at a time and let the position of one touch point be at the cursor position, while the other touch point is far away, so that the scrolling operation can be avoided because The touch point has exceeded the range of the screen and is interrupted.

To sum up, according to the electronic device and the related control method of the present invention, the touch input simulation and the mouse input simulation of the touch panel are respectively provided through the touch events detected by the touch panel, which can provide the user with more The meta-intuitive control method enables the user to have a good touch experience.
