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 implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The embodiment of the present disclosure provides a screen projection control method, and fig. 1 is a first flowchart of a screen projection control method according to an exemplary embodiment, and as shown in fig. 1, the screen projection control method includes the following steps:
103, generating an indication icon based on the touch position information;
Illustratively, the first device to which the screen projection control method is applied may be any electronic device, such as a smartphone, a tablet computer, or a wearable electronic device. The second device receiving the screen projection image may also be any electronic device with a display function, such as a smart television, a projection device, or a smart phone.
In a screen projection scene, the equipment for realizing screen projection comprises: the screen projection device provides display content, and the screen projected device displays the display content provided by the screen projection device.
In the disclosed embodiment, the first device is a screen projection device; the second device is a projected screen device.
The first device is provided with a touch screen and can trigger corresponding functions based on touch operation acting on the touch screen. Moreover, in order to detect different types of touch operations and improve the convenience of the user in using the first device, the touch screen of the first device in the disclosure can detect the touch operation within a preset distance from the touch screen. That is, the touch operation in the present disclosure may include: the touch control method comprises the following steps of suspension touch control operation without contacting the touch screen, and/or contact touch control operation contacting the touch screen. Namely: the touch screen of the first device may detect a contact touch operation in contact with the touch screen, or may detect a floating touch operation not in contact with the touch screen. Thus, the first device has an air-gap touch function.
The preset distance is determined according to detection parameters of the touch screen, and in some embodiments, the detection parameters at least include: the voltage is detected. The detection voltage is positively correlated with the preset distance, and the larger the detection voltage is, the larger the detection sensitivity of the touch screen is, and the larger the detectable distance is. For example, when the detection voltage of the touch screen is increased to a certain extent, the floating touch operation at a certain distance from the touch screen can be detected.
The second device is also provided with a display screen, which may be a touch screen or a non-touch screen. And when the second device is a projector, taking the projection screen of the second device as the display screen of the second device. In some embodiments, the wall may also be considered a projection curtain. The present disclosure is not so limited.
In some embodiments, the area of the display screen of the second device is larger than that of the first device, so that the information can be displayed through the large-screen second device after the screen is projected, and the method can be better suitable for multiple people to watch scenes, such as a conference.
In other embodiments, the display screen area of the second device is smaller than or equal to that of the first device, so that sharing among multiple users can be realized. The present disclosure does not limit the display screen area of the second device.
When the first device detects a screen projection instruction, sending a screen projection picture to the second device, so that the second device can display the screen projection picture; wherein, the screen projection instruction at least comprises: the display content of the projected screen and the equipment parameters of the projected screen equipment; the device parameter is used to indicate a projected device. In some possible embodiments, the device parameters may include: internet Protocol Address (IP Address).
Here, after the screen projection screen is transmitted, although the screen projection screen is displayed on the second device, the operation control of the screen projection screen is performed on the first device; when the screen projection picture is required to be operated, touch operation needs to be performed on the touch screen of the first device, and the function of the corresponding control is triggered.
In the embodiment of the disclosure, after sending a screen projection picture, a first device detects whether a touch operation is performed on a touch screen, acquires touch position information if the touch operation performed on the touch screen is detected, generates an indication icon based on the touch position information, and sends the indication icon to a second device. In this way, the second device can display an indication icon in addition to the screen projection screen. Then, the position of the touch operation acting on the touch screen of the first device can be known according to the indication icon displayed on the second device. In this way, the operator's line of sight may not toggle between the two devices, and may focus only on the display on the second device. Here, the operator is a person who operates the screen projection.
The touch position information is used for indicating a touch position of a touch operation applied to the first device touch screen.
In some embodiments, the touch position includes at least: the touch operation is projected at a first position on the touch screen. For example, when a finger of a user acts on a touch screen of a first device, the projection position of the finger on the touch screen is determined; when in touch control, the finger and the touch screen can be suspended on the touch screen or contacted with the touch screen.
In some embodiments, when the touch operation is a hover touch operation, the touch position further includes: and a second position of the touch operation relative to the touch screen, wherein the second position indicates the distance between the floating touch operation and the touch screen.
The indication icon may be any reference mark for indicating a touch position. The indication icon includes: a graphic type icon, a character type icon or a character type icon; for example, a mouse arrow, a circle, or the letter A may be used as the indicator icon.
In the embodiment of the present disclosure, the generated indication icons may also be different according to different types of touch operations. In some embodiments, when a floating touch operation acting on the first device touch screen is detected, different indication icons may be generated according to a distance between the floating touch operation and the touch screen. For example, indicator icons of different transparencies or indicator icons of different morphologies are generated. The transparency of the indication icon is inversely related to the distance between the floating touch operation and the touch screen. The shape of the indication icon may be set in a pairing manner according to a distance between the floating touch operation and the touch screen, for example, taking a mouse arrow as an example, the direction of the mouse arrow may be adjusted according to the distance between the floating touch operation and the touch screen. The present disclosure does not limit the form of the indication icon.
Since the indication icon is generated based on the touch position information of the touch operation applied to the touch screen, the position of the touch operation applied to the touch screen of the first device can be known according to the indication icon displayed on the display interface of the second device. Therefore, after the screen is projected, if the demonstration is needed to be performed by matching with the content displayed on the second equipment, the presenter can directly know the touch position of the first equipment acted by the presenter based on the indication icon displayed on the display interface of the second equipment, so that the presenter can switch between the first equipment and the second equipment without the sight back and forth during the demonstration and can confirm the finger touch position on the first equipment without lowering the head for multiple times, the operation purpose can be achieved by only paying attention to the indication icon on the second equipment, and the convenience of the demonstration operation during the screen projection is improved.
In some embodiments, the obtaining the touch position information if the touch operation acting on the touch screen within the preset distance from the touch screen is detected includes:
and when the touch screen is in a turned-off state, if the touch operation acting on the touch screen within a preset distance from the touch screen is detected, acquiring touch position information.
In the embodiment of the disclosure, after the screen projection picture is sent to the second device, the touch screen of the first device can be turned off. Therefore, the power consumption can be reduced, and the power of the first device can be saved.
It should be noted that, in the embodiment of the present disclosure, the touch detection function is retained when the touch screen of the first device is turned off. Thus, the purpose of touch detection can be achieved.
Here, the touch screen of the first device may be kept powered off to retain the touch detection function of the touch screen. And when the screen projection is finished, the original screen-off touch-control function is restarted. Therefore, the scene needing to be projected and the scene needing not to be projected can be distinguished, and the protection function of the touch screen is also closed after the screen is turned off under the scene needing not to be projected so as to achieve the purpose of preventing mistaken touch.
It should be further noted that, in some embodiments, when the touch screen is in a bright screen state, if a touch operation performed on the touch screen within a preset distance from the touch screen is detected, the touch position information may be obtained. As shown in fig. 2, fig. 2 is a schematic diagram of display contents of the first device according to an exemplary embodiment, and when the touch screen of the first device 201 is in a bright screen state, the touch operation performed on the touch screen within a preset distance from the touch screen may also be detected, and after an indication icon is generated, the indication icon 200 is also displayed on the touch screen of the first device. As shown in fig. 2, the circle above the 4 rows of application icons displaying the home page of the interface is the indicator icon 200.
In this way, after the indication icon is sent to the second device, the indication icon displayed on the first device and the indication icon displayed on the second device may correspond in position. Fig. 3 is a schematic diagram illustrating display contents of the second device according to an exemplary embodiment, and as shown in fig. 2 and fig. 3, the indication icon displayed on the first device is located above 4 rows of application icons on the display interface, where the screen shot is the display interface including 4 rows of application icons. The indicator icon 300 displayed on the second device 301 is also above the 4 rows of application icons. Therefore, the position of the finger of the operator on the touch screen of the first device can be prompted through the indication icon.
In some embodiments, the touch operation comprises: a floating touch operation not in contact with the touch screen, and/or a contact touch operation in contact with the touch screen;
based on the touch operation, the method further comprises:
starting an air-isolated touch function; the air-separating touch control function can detect the floating touch control operation within a preset distance from the first equipment touch control screen.
In the embodiment of the present disclosure, the touch screen of the first device may detect a contact touch operation that is in contact with the touch screen, and may also detect a floating touch operation that is not in contact with the touch screen.
Here, the touch screen includes: the touch detection assembly and the control chip; the touch detection assembly is installed on the display screen and used for detecting touch position information of a user and sending the touch position information to the control chip after the touch position information is detected. The control chip is mainly used for receiving touch position information from the touch detection component, converting the touch position information into touch point coordinates and sending the touch point coordinates to a processor (CPU) of the first equipment, and meanwhile, receiving and executing commands sent by the CPU.
In order to realize the space detection, at least two capacitor plates which respectively form a capacitor with the ground are arranged on the left side and the right side of the display screen, and the capacitor is a self-capacitance sensor and can sense the position and action change of an operator within a preset distance above the display screen. Exemplarily, when a finger approaches the display screen, capacitance change of the capacitor is caused, the touch detection component of the touch screen of the first device detects multiple groups of capacitance values and sends the multiple groups of capacitance values to the control chip, the control chip processes the multiple groups of capacitance values to obtain variation of the capacitance values, and then position coordinates and action change of the finger are judged, and an operation instruction corresponding to the action is generated, so that the air-separated touch operation of the first device is realized.
In some embodiments, the method further comprises:
generating movement information of the indication icon based on touch operation detected at continuous detection time;
sending the movement information to the second device; the movement information is used for indicating a movement path of an indication icon displayed on a screen projection picture displayed by the second equipment.
Here, the capacitance values detected by at least two capacitance plates on the touch screen are different, so that which capacitance plate the finger is closer to can be distinguished. And the distance change of the finger from the touch screen can be judged according to the difference of capacitance values detected in the two times. Multiple sets of capacitance values are detected, the movement trajectory/direction of the finger over the display screen can be analyzed, as well as whether there is a press/release action.
The maximum detection distance which can be reached by the space detection can be determined according to the detection voltage of the touch screen; the larger the detection voltage is, the larger the detection sensitivity of the touch screen is, and the larger the detectable distance is. Therefore, after the touch screen with the sensitivity capable of detecting the space touch function is selected, the floating touch operation which is not in contact with the touch screen and/or the contact touch operation which is in contact with the touch screen can be detected based on the touch screen.
In each touch, the first device side determines touch position information of touch operation based on capacitance values detected by at least two capacitance plates on the touch screen, and then, after the touch operation detected at the continuous detection time, may generate movement information of the indication icon based on the touch operation detected at the continuous detection time, and send the movement information to the second device. In this way, the second device can correspondingly move the indication icon on the displayed screen projection screen according to the movement information, and display the movement path during the movement.
Therefore, when the first device is operated, the operation position acted on the first device can be synchronously seen on the display screen of the second device, and a demonstrator does not need to switch the sight back and forth in the demonstration operation, so that the convenience of the demonstration operation is improved. After the display screen of the first device is turned off, because the operation position acting on the first device can be displayed on the second device, the corresponding touch operation can still be realized, and application scenes are increased.
In some embodiments, the obtaining the touch position information if the touch operation acting on the touch screen within the preset distance from the touch screen is detected includes:
and based on the started spaced touch function, if the floating touch operation acting on the touch screen within a preset distance from the touch screen is detected, acquiring touch position information.
Here, the touch screen of the present disclosure has an air-gap touch function, which may be turned on or off. The function is started when the air-spaced touch is needed, and the function is closed when the air-spaced touch is not needed, so that the mistaken touch caused by long-term starting of the air-spaced touch function in daily use can be reduced.
In some embodiments, the touch position information of the hover touch operation at least includes: touch coordinate information used for indicating a first position of the floating touch operation projected on the touch screen; the first position is used for determining the coordinate of the indication icon on the screen projection picture.
Here, the touch position information is used to indicate a touch position of a touch operation applied to the touch screen of the first device. The touch coordinate information is used for indicating a first position of the floating touch operation projected on the touch screen.
Because the touch operation on the touch screen of the first device aims at triggering the corresponding function, based on the touch position information, the touch coordinate information of the user on the touch screen can be known, and if the coordinate position indicated by the touch coordinate information corresponds to the control on the display interface, the function corresponding to the control can be triggered.
For the floating touch operation, the floating touch operation is not in contact with the touch screen, and the touch coordinate information of the floating touch operation may be coordinate information of a first position where the floating touch operation is projected on the touch screen.
In order to improve the convenience of operation, the indication icon generated based on the touch position information is sent to the second device, so that when the touch operation is a floating touch operation, the indication icon generated based on the touch position information carries the first position, and the first position is used for determining the coordinate of the indication icon on the screen projection picture. In this way, after the screen projection picture is displayed on the display interface of the second device, the indication icon is displayed on the first position of the screen projection picture. In this way, the indication icon displayed on the screen projection screen displayed by the second device can be made to correspond to the position of the touch operation acting on the touch screen of the first device. Then, after the position of the floating touch operation is moved on the first device, the position of the indication icon is correspondingly moved on a screen projection picture displayed by the second device, so that a basis is provided for realizing accurate touch subsequently.
Here, the floating touch operation belongs to a spatial operation, and there is touch distance information indicating a distance from the touch screen in addition to the touch coordinate information. The following describes the touch distance information of the floating touch operation:
in some embodiments, fig. 4 is a flowchart illustrating a screen projection control method according to an exemplary embodiment, where as shown in fig. 4, the method further includes:
and 105, determining the display transparency of the indication icon to be generated based on the second position of the floating touch operation distance from the touch screen.
