Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
FIG. 1 is a diagram illustrating a method of controlling screen return to a desktop in accordance with an exemplary embodiment. This embodiment is explained by taking an example of execution on the control apparatus side. The method for controlling the screen to return to the desktop is applied to first equipment with a touch panel, and comprises the following steps:
and S11, acquiring floating touch information corresponding to the floating touch operation sensed by the touch panel.
And S12, judging whether the floating touch information meets the preset gesture information.
And S13, if the floating touch information meets the preset gesture information, generating a return instruction for controlling the screen to return to the desktop.
In step S11, a touch panel is disposed on the first device, and a user performs a floating touch operation on the touch panel, so that the touch panel senses the floating touch operation, thereby generating floating touch information describing the floating touch operation.
Specifically, the touch panel may adopt a capacitive touch screen or a capacitive touch pad, and the capacitive touch screen or the capacitive touch pad may be wired in such a manner that the capacitive touch screen or the capacitive touch pad can sense a signal of direct touch and can also sense a capacitive signal within a certain height (e.g., 1-2 cm) above the surface of the capacitive touch screen. The first equipment determines coordinate information of the floating touch point on the touch panel according to the sensed capacitance signal; furthermore, the number of the floating touch points, the area of each floating touch point, the relative distance between different floating touch points and other information can be determined according to the coordinate information; according to actual needs, the floating touch information may include one or more of the above information, which collectively describe the floating touch operation of the user on the touch panel.
In step S12, the predetermined gesture information is floating touch information corresponding to a preset gesture (or floating touch operation) for returning the screen to the desktop.
In the step S13, since the floating touch information corresponding to different gestures (i.e., different floating touch operations) is necessarily different, it is determined whether the currently detected floating touch information is the floating touch information corresponding to the gesture of the preset screen returning to the desktop (i.e., the predetermined gesture information) by analyzing and judging the currently detected floating touch information; if the floating touch information meets the preset gesture information, which indicates that the floating touch operation performed by the user is a preset gesture of returning the screen to the desktop, it may be determined that a return instruction should be generated to control the screen to return to the desktop.
In the embodiment, whether the floating touch information of the user on the touch panel meets the preset gesture information is detected, and when the preset gesture information is met, the return instruction for controlling the screen to return to the desktop is generated, so that the screen can return to the desktop by adopting the floating touch operation, the limitation of returning the contact type screen to the desktop is avoided, and the use by the user is more convenient.
In one possible embodiment of the invention, a dynamic gesture of changing a finger from an open state to a pinch state can be used as a gesture of returning the screen to the desktop; then, the predetermined gesture information may be information converted from a first state information to a second state information within a preset time period, where the first state information is information corresponding to an open state of the finger, and the second state information is information corresponding to a pinch state of the finger.
Based on the predetermined gesture information, step S12 actually determines that: whether the floating touch information is converted from first state information to second state information within a preset time period or not is determined. Specifically, in some embodiments, as shown in fig. 2, step S12 may include:
s121, judging whether the floating touch information is first state information;
s122, if the floating touch information is the first state information, continuously acquiring the floating touch information, and judging whether the floating touch information changes in a preset time period and becomes second state information;
and S123, if the floating touch information is changed within the preset time period and the changed floating touch information is the second state information, judging that the floating touch information meets the preset gesture information.
In this embodiment, when it is detected that the floating touch information is converted from the first state information corresponding to the finger open state to the second state information corresponding to the finger pinch state within the preset time period, it is indicated that the floating touch operation performed by the user is that the finger is changed from the open state to the pinch state, and the gesture is the same as the preset gesture for returning the screen to the desktop, so that a return instruction is generated to control the screen to return to the desktop. Of course, in other embodiments, other gestures may also be used as the gesture for returning the screen to the desktop, and the floating touch information corresponding to the gesture may be used as the predetermined gesture information to determine whether to generate a return instruction, i.e., whether to control the screen to return to the desktop.
In describing how to implement the above steps S121 to S123 (i.e., how to determine whether the floating touch information is the first state information and is changed into the second state information) in the embodiment of the present invention, it is necessary to briefly describe the floating touch technology first.
Based on the floating touch technology, there are various types of floating touch information (including the aforementioned coordinate information, the number of floating touch points, the area of each floating touch point, the relative distance between different floating touch points, etc.) that can be detected. However, in view of the different detection accuracy of the floating touch by different devices, the obtained floating touch information is also different.
Taking four-finger touch as an example (in other embodiments, the control of returning the screen to the desktop can also be realized by three fingers, five fingers, and the like), when the four fingers of the user are opened and in a suspension state, 3 to 4 lowest points can be read, that is, 3 to 4 floating touch points can be detected at the time. When a user pinches the four fingers together, 3-4 floating touch points can still be detected for equipment with high detection precision; for a device with low detection precision, only one floating touch point is generally detected, that is, the floating touch points corresponding to the four fingers are gathered together in a pinch state, the device with low detection precision cannot accurately distinguish the floating touch points, and only the floating touch points can be integrally regarded as one floating touch point, but the area of the floating touch point is larger than that of the real floating touch point (the area of the capacitance change area caused by the four fingers is larger than that of the capacitance change area caused by one finger).
According to the above analysis, in a possible embodiment, for a device with low detection accuracy, the steps S121 to S123 may be implemented according to the number of floating touch points, the relative distance between the floating touch points, and the area of the floating touch points, which are as follows:
in step S121, if the number of the floating touch points in the floating touch information is multiple, further determining whether a relative distance between the floating touch points is greater than a preset distance threshold; if the relative distance between the floating touch points is greater than the preset distance threshold, it is determined that the floating touch information is the first state information, and the step S122 is continuously executed.
In step S122, it is continuously determined whether the number of the floating touch points in the floating touch information changes from one to multiple within a preset time period, if the number of the floating touch points in the floating touch information changes from one to multiple within the preset time period, it is further determined whether the area of the floating touch points is greater than a preset area threshold, and if the area of the floating touch points is greater than the preset area threshold, it is determined that the floating touch information changes within the preset time period and changes into the second state information, and it may be determined in step S123 that the floating touch information satisfies predetermined gesture information; otherwise, determining that the floating touch information is invalid information, returning to step S121, and re-determining whether the subsequently generated floating touch information meets the predetermined gesture information.
In this embodiment, the preset area threshold is an area of a floating touch point formed when a single finger touches; under the condition that the number of the floating touch points in the floating touch information is multiple, the relative distance between the floating touch points is further judged to be larger than a preset distance threshold value, so that the plurality of floating touch points are formed by opening a plurality of fingers, and the floating touch information can be determined to be first state information; changing the number of the floating touch points in the floating touch information from multiple to one in a preset time period, wherein the area of the floating touch points is larger than a preset area threshold value, so that the plurality of fingers are changed from an open state to a pinch state, the floating touch information can be determined to be changed in the preset time period and changed into the second state information, the floating touch information finally obtained meets preset gesture information, and a return instruction is generated to control the screen to return to the desktop; according to the method and the device, the screen can be returned to the desktop by adopting the suspension touch information, so that the limitation of returning the contact screen to the desktop is avoided, and the use by a user is more convenient.
In another possible embodiment, for a device with high detection accuracy, the steps S121 to S123 may be implemented according to the number of floating touch points and the relative distance between different floating touch points, which is specifically as follows:
in step S121, if the number of the floating touch points in the floating touch information is multiple, further determining whether a relative distance between the floating touch points is greater than a preset first distance threshold; if the relative distance between the floating touch position points is greater than a preset first distance threshold, determining that the floating touch information is first state information, and continuing to execute step S122.
In step S122, it is continuously determined whether the number of the floating touch points is unchanged within the preset time period, if the number of the floating touch points is unchanged within the preset time period, it is continuously determined whether the relative distance between the floating touch points in the floating touch information is decreased within the preset time period and the decreased relative distance is smaller than a preset second distance threshold, if the relative distance between the floating touch points is decreased within the preset time period and the decreased relative distance is smaller than the preset second distance threshold, it is determined that the floating touch information is changed and changed into the second state information within the preset time period, and it may be determined in step S123 that the floating touch information satisfies predetermined gesture information; otherwise, determining that the floating touch information is invalid information, returning to step S121, and re-determining whether the subsequently generated floating touch information meets the predetermined gesture information.
In this embodiment, the first distance threshold is greater than or equal to the second distance threshold, and may be specifically set according to the actual application requirement; for example, the first distance threshold may be set to 3cm, the second distance threshold may be set to 1cm, or both the first distance threshold and the second distance threshold may be set to 2 cm. Under the condition that the number of the floating touch points in the floating touch information is multiple, further judging that the relative distance between the floating touch points is greater than a preset first distance threshold value, and showing that the finger distance corresponding to each floating touch point is relatively long, the finger can be regarded as an open state, so that the floating touch information can be determined to be first state information; the number of the floating touch points is unchanged in the preset time period, the relative distance between the floating touch points is reduced, and the reduced relative distance is smaller than a preset second distance threshold value, which shows that the finger distance corresponding to each floating touch point is reduced, and the fingers can be regarded as a plurality of fingers changing from an open state to a pinch state, so that the floating touch information can be determined to change in the preset time period and become the second state information, the floating touch information finally obtained meets the preset gesture information, and a return instruction is generated to control the screen to return to the desktop; according to the method and the device, the screen can be returned to the desktop by adopting the suspension touch information, so that the limitation of returning the contact screen to the desktop is avoided, and the use by a user is more convenient.
In this embodiment of the present invention, after the return instruction is generated, the method for returning the control screen to the desktop further includes:
if the screen is the screen of the first equipment, directly executing the return instruction;
alternatively, the first and second electrodes may be,
and if the screen is the screen of a second device connected with the first device, sending the return instruction to the second device, so that the second device controls the screen to return to the desktop of the second device after receiving the return instruction.
In this embodiment, whether the floating touch information corresponding to the floating touch operation performed by the user on the touch panel meets the predetermined gesture information is detected to determine whether the floating touch operation performed by the user is a preset screen return desktop gesture, and when the floating touch operation performed by the user is the preset screen return desktop gesture, a return instruction for controlling the screen to return to the desktop is generated.
FIG. 3 is an illustration of another method of controlling a screen to return to a desktop, in accordance with an exemplary embodiment. As shown in fig. 3, this embodiment is directed to an application scenario in which the screen is a screen of the second device, and the screen of the second device is controlled by the first device to return to the desktop, and includes the following steps:
and S21, the first device establishes connection with the second device.
The connection may be a wired connection, such as a cable or an optical fiber connection, or a wireless connection, such as a wifi connection or a bluetooth connection, or a cellular mobile communication (e.g. 3G/4G) connection.
And S22, the user performs a floating touch operation on the touch panel of the first device.
The touch panel is disposed on the first device, and the touch panel is, for example, a capacitive touch screen or a capacitive touch pad.
And S23, the first equipment senses the floating touch operation through the touch panel and generates corresponding floating touch information.
The touch panel adopts a capacitive touch screen or a capacitive touch pad, and the capacitive touch screen or the capacitive touch pad can sense a signal directly touched by the capacitive touch screen or the capacitive touch pad in a wiring mode and can also sense a capacitive signal 1-2 cm above the surface of the capacitive touch screen or the capacitive touch pad. The first device converts the sensed capacitance signal into floating touch information, such as coordinate information of floating touch points, the number of the floating touch points, relative distances between the floating touch points, and areas of the floating touch points.
And S24, the first equipment judges whether the floating touch information meets the preset gesture information.
In this embodiment, the step S24 can be implemented by referring to the step S12, which is not described herein again.
And S25, if the floating touch information meets the preset gesture information, the first device generates a return instruction for controlling the screen of the second device to return to the desktop, and sends the return instruction to the second device so that the screen of the second device returns to the desktop of the second device.
And if the floating touch information meets the preset gesture information, the floating touch operation executed by the user is a preset gesture of returning the screen to the desktop, the first device generates a return instruction and sends the return instruction to the second device.
And S26, the second device controls the screen of the second device to return to the desktop of the second device according to the received return instruction.
It is understood that what is not described in detail in this embodiment may be referred to in other embodiments and will not be described in detail here.
