The method for determining the screen expansion direction provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
In the screen expansion direction determining method provided in the embodiment of the present application, an execution main body of the screen expansion direction determining method may be an electronic device or a functional module or a functional entity capable of implementing the screen expansion direction determining method in the electronic device, the electronic device mentioned in the embodiment of the present application includes, but is not limited to, a mobile phone, a tablet computer, a camera, a wearable device, and the like, and the screen expansion direction determining method provided in the embodiment of the present application is described below with the electronic device as the execution main body.
The embodiment of the application provides a method for determining a screen expansion direction, which is applied to first display equipment, wherein the first display equipment comprises a first antenna and a second antenna which are arranged in a separated mode. It should be noted that, the farther the setting distance between the first antenna and the second antenna is, the higher the accuracy of the final determination result is, and the specific distance may be determined according to the device volume of the first display device, which is not limited in this embodiment of the present application.
As shown in fig. 1, the method for determining a screen expansion direction provided in the embodiment of the present application may include steps 101 to 102:
Optionally, the first display device and the second display device may communicate through a wired connection manner, for example, the first display device and the second display device may be connected through an HDMI interface in a wired manner; the communication can also be performed in a wireless connection mode, for example, the first display device and the second display device can be under the coverage of the same local area network, and are connected in a wireless network connection mode, or can be connected through bluetooth; the method can be determined according to actual use requirements, and is not limited in the embodiment of the application.
Optionally, the first antenna and the second antenna may be bluetooth antennas.
Optionally, the first display device may scan whether a display device with a display function exists within a preset range with a radius d, and if the second display device is detected, the first signal strength of the second display device may be obtained through the first antenna, and the second signal strength of the second display device may be obtained through the second antenna.
Specifically, the first display device may transmit a first signal to the second display device through the first antenna and transmit a second signal to the second display device through the second antenna, and thereafter, the first display device may acquire a first signal strength detected by the second display device through the first antenna and acquire a second signal strength detected by the second display device through the second antenna. The first Signal Strength may be a first Received Signal Strength Indication (RSSI) value and the second Signal Strength may be a second RSSI value.
Based on the scheme, after the first display device sends signals to the second display device through different antennas, the first display device can read two RSSI values fed back by the second display device, therefore, on the one hand, the first display device may determine the position of the second display device based on the magnitude relationship between the two RSSI values, and on the other hand, as long as the second display device can successfully receive the first signal and the second signal, the second display device may obtain the two RSSI values, and the first display device may determine the position of the second display device according to the RSSI value fed back by the second display device.
It should be noted that the wireless communication systemDuring transmission, the RSSI may regularly decay with the distance d between the receiving node and the transmitting node, and the relationship between the decay of the RSSI and the distance d is: RSSI ═ RSSI0-10n x lg d, wherein RSSI0The RSSI value received by the receiving node is d is 1m, and n is a constant. That is, since the first antenna and the second antenna are disposed at different positions, the RSSI acquired by the first antenna is different from the RSSI acquired by the second antenna in size, and the farther the distance between the antenna and the second display device is, the smaller the value of the acquired RSSI is.
It should be noted that, because there are many interference factors in the existing network test, for example, fluctuation of RSSI statistics, signal reflection, disturbance of surrounding human bodies, etc., RSSI disturbance in the existing network can be filtered out through three filtering algorithms, i.e., mean filtering, median filtering, and gaussian filtering. As shown in fig. 2, experiments can show that the three different filtering algorithms can all be obtained: within the range of 4m, the absolute error value of the RSSI test distance is within 20cm-30 cm. Since the distance between two display devices extending the screen in daily life is generally within 2m, it is effective to locate the relative position between the two display devices by the RSSI of this distance accuracy.
Optionally, after the first signal strength and the second signal strength are obtained, under the condition that the first signal strength is greater than a first threshold and the second signal strength is greater than the first threshold, the first display device may display first prompt information, where the first prompt information may be used to prompt a user to confirm a screen display mode, and the screen display mode may at least include screen expansion; thereafter, the first display device may receive a first input by the user; and in response to the first input, determining the magnitude of the first signal strength and the second signal strength.
Optionally, the first display device may display the first prompt information when receiving a preset trigger operation of the user, for example, the preset trigger operation may be that the user selects the target file through a right mouse button and drags the target file.
It should be noted that, under the condition that the screen display mode is screen expansion, the first display device needs to divide the complete screen information originally displayed on the first display device into first information and second information, and then determines on which device the first information and the second information are respectively displayed according to the screen expansion direction, so that the first display device needs to determine whether the screen display mode of the first display device is screen expansion according to user input.
It should be noted that the first threshold is a signal strength threshold, that is, only when the signal strength detected by the antenna is greater than the first threshold, the first display device may successfully perform information transmission with the second display device.
Based on the above scheme, under the condition that the first signal intensity and the second signal intensity are both greater than the first threshold, the user can trigger the first display device to determine that the screen display mode is screen expansion according to the displayed first prompt information, and therefore the first display device can judge the sizes of the first signal intensity and the second signal intensity in the screen display mode, and a basis is provided for subsequently determining the screen expansion direction according to the sizes of the signal intensities.
Optionally, the screen display mode may further include screen duplication. Under the condition that the first signal strength is greater than the first threshold value and the second signal strength is greater than the first threshold value, the first display device can display the first prompt message; thereafter, the first display device may receive a second input by the user; and displaying the full screen information of the first display device on the second display device in response to the second input.
It should be noted that, when the screen display mode is screen duplication, the first display device needs to transmit the complete screen information displayed on the first display device to the second display device for displaying, and therefore, the first display device needs to determine whether the screen display mode of the first display device is screen duplication according to user input.
It should be noted that the screen duplication refers to displaying the complete screen information displayed on the first display device on the second display device, that is, the first display device and the second display device simultaneously display the same screen information.
Based on the above scheme, since the user can trigger the first display device to determine that the screen display mode is the screen copy according to the displayed first prompt information under the condition that the first signal strength and the second signal strength are both greater than the first threshold, the first display device can determine to execute the display operation corresponding to the screen copy.
Wherein the second direction is different from the first direction. For example, when the first direction is the left side, the second direction may be the right side or the upper side.
Illustratively, the first antenna 31 is disposed on the left side of the inside of the first display device 30, and the second antenna 32 is disposed on the right side of the inside of the first display device 30. As shown in fig. 3(a), in the case that the first signal strength RSSI 1 is greater than the second signal strength RSSI 2, the first display device 30 may determine that the second display device 40 is located on the left side of the first display device 30, thereby determining that the screen expansion direction of the first display device 30 is left; as shown in fig. 3(b), in the case where the first signal strength RSSI 1 is less than the second signal strength RSSI 2, the first display device 30 may determine that the second display device 40 is located at the right of the first display device 30, thereby determining that the screen expansion direction of the first display device 30 is right.
Optionally, in order to improve the accuracy of judging the screen expansion direction, the first display device may further obtain first signal transmission time from the first antenna to the second display device and second signal transmission time from the second antenna to the second display device; determining the screen expansion direction of the first display device as a first direction under the condition that the first signal transmission time is shorter than the second signal transmission time and the first signal intensity is greater than the second signal intensity; and determining the screen expansion direction of the first display device as a second direction under the condition that the first signal transmission time is longer than the second signal transmission time and the first signal intensity is smaller than the second signal intensity.
Considering that the RSSI has a special angle in practical use and an unstable problem caused by a multipath environment, on the basis of judging the distance according to the RSSI, the judgment of a time dimension can be added, so that the difference of directions is strengthened. In particular, the magnitude of the signal transmission time is proportional to the distance between the transmitting node and the receiving node. Accordingly, the first display device may record a time T1 of transmitting the first signal, a time T2 of transmitting the second signal, a time T3 of receiving the third signal, and a time T4 of receiving the fourth signal, then determine a first signal transmission time from a time T1 of transmitting the first signal and a time T3 of receiving the third signal, determine a second signal transmission time from a time T2 of transmitting the second signal and a time T4 of receiving the fourth signal, and determine a screen expanding direction of the first display device as a first direction in a case where the first signal transmission time is less than the second signal transmission time and the first signal strength is greater than the second signal strength; and determining the screen expansion direction of the first display device as a second direction under the condition that the first signal transmission time is longer than the second signal transmission time and the first signal intensity is smaller than the second signal intensity.
Based on the scheme, the screen expansion direction of the first display device can be judged by combining two dimensions of signal transmission time and received signal strength, so that the judgment accuracy of the screen expansion direction can be improved.
Optionally, after determining that the screen expansion direction of the first display device is the first direction, the first display device may cancel displaying the complete screen information on the first display device, display the first information, and display the second information on the second display device; after determining that the screen expansion direction of the first display device is the second direction, the first display device may cancel displaying the complete screen information on the first display device, display the second information on the first display device, and display the first information on the second display device; wherein the complete screen information includes the first information and the second information, and the second information is located in a first direction of the first information.
Illustratively, the first direction is taken as the right, and the second direction is taken as the left. As shown in fig. 4, the full screen information 41 includes first information 42 and second information 43, and the second information 43 is located at the right of the first information 42. After determining that the screen expansion direction of the first display device is right, the first display device may cancel displaying the complete screen information 41 on the first display device, display the first information 42, and display the second information 43 on the second display device; after determining that the screen expansion direction of the first display device is left, the first display device may cancel displaying the full screen information 41 on the first display device, display the second information 43 on the first display device, and display the first information 42 on the second display device.
Based on the scheme, different screen information can be displayed on the first display device and the second display device according to the screen expansion direction, so that the screen can be effectively expanded in the correct direction, and convenience in operation and checking of a user is improved.
Optionally, in the process of performing screen expansion or screen duplication on the first display device and the second display device, the first display device may monitor the first signal strength and the second signal strength in real time; and controlling the first display device to be disconnected from the second display device under the condition that the first signal strength is smaller than the first threshold value or the second signal strength is smaller than the first threshold value.
Based on the scheme, the first display device and the second display device can be controlled to be disconnected under the condition that the first signal intensity is smaller than the first threshold value or the second signal intensity is smaller than the first threshold value, so that the screen expansion or screen copying can be stopped when the first display device and the second display device are far away.
In the embodiment of the application, the first display device comprises the first antenna and the second antenna which are separately arranged, and the arrangement positions of the first antenna and the second antenna are different, so that the signal strength of the second display device obtained through the two antennas is different, and on the basis, the placement position of the second display device relative to the first display device can be judged according to the first signal strength and the second signal strength, so that the screen expansion direction of the first display device is determined.
