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 flow diagram illustrating a method for controlling screen unlocking in accordance with an exemplary embodiment. The present embodiment is explained by taking an example of execution on the first device side. The method for controlling the unlocking of the screen 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 an unlocking instruction for unlocking the control target screen.
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 unlocking the screen.
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 preset screen unlocking gesture (i.e., the preset 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 screen unlocking gesture, it may be determined that an unlocking instruction should be generated to control the target screen to be unlocked.
In the embodiment, whether the suspension 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 unlocking instruction for controlling unlocking of the target screen is generated, so that the screen is unlocked by adopting suspension touch operation, limitation of contact unlocking is avoided, and the touch panel is more convenient for the user to use.
In one possible embodiment of the invention, a dynamic gesture of changing fingers from a pinch state to an open state can be used as a gesture of unlocking the screen; 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 a finger pinching state, and the second state information is information corresponding to a finger opening state.
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 pinch state to the second state information corresponding to the finger open 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 pinch state to the open state, and the gesture is the same as the preset screen unlocking gesture, so that an unlocking instruction is generated to control the target screen to be unlocked. Of course, in other embodiments, other gestures may also be used as the screen unlocking gesture, and the floating touch information corresponding to the gesture may be used as the predetermined gesture information to determine whether to generate an unlocking instruction, that is, whether to control the target screen to be unlocked.
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, screen unlocking control 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 moment. 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 and the area of the floating touch points, which are specifically as follows:
in step S121, if the number of the floating touch points in the floating touch information is one, further determining whether the area of the floating touch point is greater than a preset area threshold; if the area of the floating touch point is larger than the preset area threshold, determining that the floating touch information is the first state information, and continuing to execute step S122.
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, and 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 determined that the floating touch information changes within the preset time period and changes to 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 one, further judging that the area of the floating touch points is larger than a preset area threshold value, and indicating that the floating touch points are formed by kneading a plurality of fingers, so that the floating touch information can be determined to be first state information; the number of the floating touch points in the floating touch information is continuously judged to be changed from one to a plurality within a preset time period, which indicates that a plurality of fingers are changed from a pinch state to a spread state, so that the floating touch information can be determined to be changed and changed into the second state information within the preset time period, the floating touch information finally obtained meets the preset gesture information, and an unlocking instruction is generated to control the target screen to be unlocked; according to the touch screen unlocking method and device, the screen can be unlocked by adopting the suspension touch information, limitation of contact unlocking is avoided, and the touch screen unlocking device and device are more convenient for users to use.
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 smaller than a preset first distance threshold; if the relative distance between the floating touch position points is smaller 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 relative distance between the floating touch points in the floating touch information increases within the preset time period and whether the increased relative distance is greater than a preset second distance threshold, and if the relative distance between the floating touch points increases within the preset time period and the increased relative distance is greater than the preset second distance threshold, the relative distance changes and becomes the second state information within the preset time period, so that it may be determined in step S123 that the floating touch information satisfies the 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 smaller 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 1cm, the second distance threshold may be set to 3cm, 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 smaller than a preset first distance threshold value, and showing that the finger distance corresponding to each floating touch point is short and can be regarded as a pinch state, so that the floating touch information can be determined to be first state information; by continuously judging that the relative distance between the floating touch points is increased in the preset time period and the increased relative distance is larger than a preset second distance threshold value, the finger distance corresponding to each floating touch point is increased, and the fingers can be considered to be changed from a pinch state to a spread state, so that 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 the preset gesture information, and an unlocking instruction is generated to control the target screen to be unlocked; according to the touch screen unlocking method and device, the screen can be unlocked by adopting the suspension touch information, limitation of contact unlocking is avoided, and the touch screen unlocking device and device are more convenient for users to use.
In an embodiment of the present invention, after the unlocking instruction is generated, the method for controlling unlocking of a screen further includes:
if the target screen is the screen of the first equipment, directly executing the unlocking instruction;
or,
and if the target screen is the screen of a second device connected with the first device, sending the unlocking instruction to the second device so that the second device unlocks the target screen after receiving the unlocking 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 unlocking gesture, and when the preset screen unlocking gesture is performed, an unlocking instruction for controlling unlocking of the target screen is generated to unlock the screen, so that the screen can be unlocked by using the floating touch operation, limitation of contact unlocking is avoided, and the use by the user is facilitated.
FIG. 3 is another method of controlling screen unlocking, according to an exemplary embodiment. As shown in fig. 3, the embodiment is directed to an application scenario in which a target screen is a screen of a second device, and a screen of the second device is unlocked by a first device, 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 an unlocking instruction for controlling unlocking of the screen of the second device, and sends the unlocking instruction to the second device for unlocking the screen.
And if the floating touch information meets the preset gesture information, the floating touch operation executed by the user is a preset screen unlocking gesture, the first device generates an unlocking instruction and sends the unlocking instruction to the second device.
And S26, the second device unlocks the screen of the second device according to the received unlocking 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.
