[0053] Exemplary embodiments are described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numbers in different drawings represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible implementations consistent with the present disclosure. Rather, they are merely examples of device control methods, electronic devices, storage media, and program products consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0054] Figure 1 This is a flow chart of a device control method according to an exemplary embodiment. The device control method can realize the control of a display device by an electronic device. Figure 1 As shown, the electronic device executing the device control method may include the following steps:

[0055] Step 101: Responding to a control instruction, obtaining motion parameters of an electronic device;

[0056] Step 102: Determine a target operating frequency of the electronic device based on the motion parameters of the electronic device;

[0057] Step 103: Control a display device connected to the electronic device based on the target operating frequency.

[0058] In the embodiments of the present disclosure, electronic devices may include mobile terminal devices and wearable electronic devices. Mobile terminal devices include mobile phones, tablet computers, etc., and wearable electronic devices include smart bracelets, smart watches, etc.; the above-mentioned display devices may include laptop computers, desktop computers or televisions, etc., and the embodiments of the present disclosure do not limit this.

[0059] For example, the device control method can be applied in scenarios where a mobile phone is used as an external input device. For office and meeting purposes, a mobile phone can be used to directly control a display device to display and turn pages of office documents or explain meeting videos. Alternatively, for gaming and entertainment purposes, a mobile phone can be used to control the audio and video on a television, select game modules, and control the display position of the pointer on the television during gaming to perform game operations.

[0060] In embodiments of the present disclosure, an electronic device can function as an external input device via a built-in communication module. The communication module includes an ultra-wideband module or a short-range communication module. The electronic device can communicate with a display device via short-range wireless communication, and can also communicate with the display device via the ultra-wideband module.

[0061] It should be noted that the electronic device can first obtain the motion parameters of the electronic device through the motion sensor, convert the motion parameters of the electronic device, and finally send the converted parameters to the display device through the built-in communication module to achieve control of the display device.

[0062] The electronic device as an external input device refers to the electronic device being used as a keyboard, mouse, or game controller, etc. For example, when the electronic device is used as a mouse, the electronic device is used to simulate the functions of a mouse, such as moving a pointer, clicking, or dragging.

[0063] In step 101, the control instruction is generated when the electronic device needs to control the display device. The electronic device obtains the motion parameters of the electronic device in response to the control instruction.

[0064] It should be noted that the electronic device can generate a control instruction based on an operation or instruction on the electronic device. For example, in one embodiment, the control instruction can be generated in response to a key operation on the electronic device; in another embodiment, the control instruction can be generated in response to a voice or gesture instruction directed at the display device; and in yet another embodiment, the control instruction can be generated when the electronic device detects that the distance between the electronic device and the display device meets a preset distance condition.

[0065] Among them, the above-mentioned key operation can be to trigger a physical key, such as double-clicking the power key, double-clicking the volume key, etc.; it can also act on a virtual key operation displayed on the display screen of the electronic device.

[0066] The above-mentioned voice command directed at the display device can be characterized as requiring an electronic device to control the display device. For example, a voice command directed at a television or a computer, for example, requires an electronic device to control the television or the computer. The voice command directed at the display device can be sent directly by the user to the electronic device, or it can be sent by another electronic device to the electronic device.

[0067] The aforementioned gesture command directed at the display device may also indicate a need for the electronic device to control the display device. The finger command may include tracing a preset gesture for controlling the display device on the screen of the electronic device or performing a preset gesture directed at the camera of the electronic device. Preset gestures may include drawing a triangle or a circle, etc., which are not limited in the present embodiment.

[0068] In the embodiments of the present disclosure, obtaining motion parameters of an electronic device can be achieved by providing various motion sensors in the electronic device. For example, an accelerometer can be provided in the electronic device to obtain acceleration data of the electronic device through the accelerometer; and / or a gyroscope can be provided in the electronic device to obtain angular velocity data through the gyroscope, etc., which are not limited in the embodiments of the present disclosure.

[0069] It should be noted that by obtaining the motion parameters of the electronic device, the motion state and position change of the electronic device in three-dimensional space can be determined, laying a data foundation for subsequent control of the display device.

[0070] In step 102 , the target operating frequency of the electronic device is determined based on the motion parameters of the electronic device, which indicates that the target operating frequency of the electronic device is not fixed but can be changed based on changes in the motion parameters of the electronic device.

[0071] In the embodiment of the present disclosure, determining the target operating frequency of the electronic device based on the motion parameter of the electronic device includes: determining the target operating frequency based on a comparison result of the motion parameter of the electronic device and a preset parameter threshold.

[0072] Exemplarily, in one embodiment, when the motion parameter of the electronic device is greater than the first preset parameter threshold, the target operating frequency is determined to be the first preset frequency; when the motion parameter of the electronic device is less than or equal to the first preset parameter threshold, the target operating frequency is determined to be the second preset frequency; wherein the first preset frequency is greater than the second preset frequency.

[0073] In another embodiment, when the motion parameter of the electronic device is greater than the first preset parameter threshold, the target operating frequency is determined to be the first preset frequency; when the motion parameter of the electronic device is less than or equal to the first preset parameter threshold and greater than the second preset parameter threshold, the target operating frequency is determined to be the second preset frequency; when the motion parameter of the electronic device is less than the second preset parameter threshold, the target operating frequency is determined to be the third preset frequency; wherein the first preset frequency is greater than the second preset frequency, and the second preset frequency is greater than the third preset frequency.

[0074] It should be noted that the above-mentioned motion parameters include the motion speed, motion distance or motion acceleration of the electronic device, etc., and the embodiments of the present disclosure are not limited to this.

[0075] The target operating frequency refers to the frequency at which the electronic device transmits data (eg, motion parameters) to the display device, that is, the target operating frequency determines the rate at which the electronic device sends data to the connected display device.

[0076] The target operating frequency can be set according to actual conditions. For example, the target operating frequency can be set within a range of 20 Hz to 100 Hz, which is not limited in the embodiment of the present disclosure.

[0077] It can be understood that determining the target operating frequency of an electronic device based on the motion parameters of the electronic device can improve the flexibility of the electronic device in setting the target operating frequency, so as to ensure that the electronic device responds to user operations in a timely manner when controlling the display device, so that the user can feel the smoothness and real-time nature of the operation of the electronic device, thereby improving the user experience.

[0078] In step 103, controlling the display device connected to the electronic device based on the target operating frequency includes: controlling the rate at which the electronic device sends data to the connected display device based on the target operating frequency, and controlling the display device based on the sent data.

[0079] In the embodiment of the present disclosure, the electronic device and the display device can be connected via short-range wireless communication, and the electronic device converts the motion parameters and transmits the converted parameters to the display device via short-range wireless communication.

[0080] It should be noted that after the display device receives the converted parameters transmitted by the electronic device, it will control the display position of the pointer on the display screen of the display device according to the received converted parameters; or control the position of the highlighted area on the display screen of the display device. The highlighted area is used to indicate the position of the display screen currently selected by the user, so as to select or navigate the content in the highlighted area.

[0081] It is understood that the display position of the pointer or highlighted area on the display device is adjusted based on the target operating frequency of the electronic device. In this way, the pointer or highlighted area moves on the screen of the display device following the movement of the electronic device, maintaining synchronization and smoothness during user operation.

[0082] In the embodiment of the present disclosure, the motion parameters of the electronic device are obtained in response to a control instruction, and based on the motion parameters of the electronic device, the target operating frequency of the electronic device is determined, and then based on the target operating frequency, the display device connected to the electronic device is controlled. It can be seen that, on the one hand, the embodiment of the present disclosure can control the display device through the electronic device, thereby improving the convenience of the user in controlling the display device; on the other hand, compared with using a fixed operating frequency to control the display device, the embodiment of the present disclosure can flexibly select different target operating frequencies to control the display device according to the motion parameters of the electronic device, thereby not only making the movement of the electronic device and the display of the display device more synchronized, but also realizing dynamic adjustment of the operating frequency of the electronic device to reduce the power consumption of the electronic device in controlling the display device.

[0083] In one embodiment, determining a target operating frequency of the electronic device based on a motion parameter of the electronic device includes:

[0084] When the motion parameter of the electronic device is greater than a preset parameter threshold, determining the target operating frequency to be a first preset frequency;

[0085] When the motion parameter of the electronic device is less than or equal to the preset parameter threshold, determining the target operating frequency to be a second preset frequency;

[0086] The first preset frequency is greater than the second preset frequency.

[0087] In the embodiment of the present disclosure, the motion parameters of the electronic device may include: the motion speed of the electronic device or the motion distance of the electronic device, and may also include the acceleration, angular velocity, etc. of the electronic device.

[0088] Exemplarily, when the motion parameter of the electronic device is motion speed, when the first motion speed of the electronic device is greater than the preset speed threshold, the target operating frequency is determined to be the first preset frequency; when the second motion speed of the electronic device is less than or equal to the preset speed threshold, the target operating frequency is determined to be the second preset frequency.

[0089] It is understood that the electronic device sends the converted parameters to the connected display device at a first preset frequency, and the electronic device sends the converted parameters to the connected display device at a second preset frequency. Here, when the first movement speed of the electronic device is greater than the second movement speed, the first preset frequency of the electronic device sending the converted parameters to the connected display device is greater than the second preset frequency.

[0090] It should be noted that the larger the motion parameters of the electronic device, the higher the operating frequency of the electronic device needs to be, so that the position changes of the electronic device can be better reflected on the display screen of the display device connected to the electronic device, making the control of the electronic device to the display device more synchronized.

[0091] The motion parameters can be obtained by a motion sensor of the electronic device. For example, the acceleration of the electronic device can be obtained by an accelerometer, and the rotation direction and angular velocity of the electronic device can be obtained by a gyroscope, etc., although this disclosure does not limit this. Here, the acceleration of the electronic device can be obtained by an accelerometer, and then the speed of the electronic device can be obtained by converting the acceleration.

[0092] It is understood that when the first preset frequency is greater than the second preset frequency, the power loss of the electronic device operating at the first preset frequency is greater than the power loss of the electronic device operating at the second preset frequency. Therefore, switching the target operating frequency of the electronic device based on the motion parameters of the electronic device can reduce the power loss of the electronic device.

[0093] In the embodiment of the present disclosure, the target operating frequency of the electronic device is determined based on the result of comparing the motion parameters of the electronic device with a preset threshold, thereby achieving precise control of the display device and reducing the power consumption of the electronic device in controlling the display device.

[0094] In one embodiment, controlling a display device connected to an electronic device based on a target operating frequency includes:

[0095] Converting motion parameters of the electronic device using a coordinate conversion algorithm to obtain converted parameters;

[0096] Based on the target operating frequency, the converted parameters are sent to the display device to adjust the display position of the pointer in the display device.

[0097] In the embodiment of the present disclosure, the coordinate conversion algorithm includes a coordinate system definition and mutual conversion algorithm, a coordinate translation transformation algorithm, a coordinate projection transformation algorithm, etc., which is not limited in the embodiment of the present disclosure.

[0098] The converted parameters include the coordinates of the pointer in the display device after movement. Here, the motion parameters of the electronic device are converted to obtain the converted parameters, including:

[0099] The coordinates of the electronic device after it moves are determined based on the coordinates of the electronic device before it moves, the angular velocity value of the electronic device, and the acceleration value of the electronic device; the coordinates of the pointer in the display device after it moves are determined based on the coordinates of the pointer in the display device before it moves, the movement direction and distance of the electronic device, and the ratio of the movement distance of the electronic device to the movement distance of the pointer of the display device.

[0100] The coordinates of the pointer before movement in the display device may be the initial coordinates of the pointer, or the coordinates before one of the multiple movements of the pointer, which is not limited in the embodiment of the present disclosure.

[0101] The ratio of the movement distance of the above-mentioned electronic device to the movement distance of the pointer in the display device can be determined according to the distance between the electronic device and the display device, can be determined according to the size of the display device, or can be set according to user-defined data. The embodiment of the present disclosure does not limit this.

[0102] It should be noted that the electronic device can send a pointer control instruction to the display device. The pointer control instruction carries the coordinates of the pointer after movement. The electronic device sends the coordinates of the pointer after movement to the display device at the target operating frequency. The display device controls the pointer to move to the coordinate position after movement in the display screen in response to the pointer control instruction. In this way, the electronic device can adjust the display position of the pointer in the display device.

[0103] In the embodiment of the present disclosure, the motion parameters of the electronic device are converted through a coordinate conversion algorithm to obtain the converted parameters, and the converted parameters are sent to the display device at the target operating frequency. This can more accurately adjust the display position of the pointer in the display device and reduce the power consumption of the electronic device in controlling the display device.

[0104] In one embodiment, the motion parameters of the electronic device are converted using a coordinate conversion algorithm to obtain the converted parameters, including:

[0105] The motion parameters of the electronic device are converted by a coordinate conversion algorithm executed by a sensor main processing chip of the electronic device to obtain converted parameters.

[0106] In the disclosed embodiment, the sensor hub is a hardware and software solution based on a low-power microcontroller unit (MCU) and a lightweight real-time operating system, and is used to fuse data from different types of sensors to achieve functions that can only be achieved by combining data from multiple sensors.

[0107] For example, Figure 2 FIG. 1 is a structural diagram of a sensor processing chip according to an exemplary embodiment. Figure 2 As shown, the sensor processing chip includes:

[0108] Hardware Abstraction Layer (HAL): It is the interface between the sensor framework and motion sensors (such as accelerometers and gyroscopes). The Sensors HAL defines a series of functions for controlling motion sensors.

[0109] Service layer (Sensor Service): used to run application algorithms, including algorithms for processing motion sensor data, such as coordinate conversion algorithms.

[0110] User layer (Client): used to process user accounts, such as storing user accounts, which store configuration parameters of electronic devices.

[0111] In an embodiment of the present disclosure, based on the target operating frequency and the sensor main control chip of the electronic device, controlling the display device includes: the sensor main processing chip of the electronic device converts the motion parameters of the electronic device transmitted by the motion sensor, and converts the motion parameters into position changes of the electronic device, obtains the display position of the pointer in the display device based on the position change of the electronic device, and the electronic device sends the display position of the pointer to the display device at the target operating frequency.

[0112] It should be noted that the sensor processing chip can achieve real-time control of the motion sensor when the central processing unit (CPU) of the electronic device is dormant, thereby reducing the power consumption of the pointer in the electronic device controlling the display device.

[0113] In the embodiment of the present disclosure, the display position of the pointer in the display device is controlled by the target operating frequency and the sensor main processing chip of the electronic device, so that the display device can be controlled more flexibly, and the motion parameters transmitted by the motion sensor do not need to be processed through the application layer and the central processing unit of the electronic device. That is, the use of the sensor main control chip can reduce the power consumption of the electronic device in controlling the display device.

[0114] In one embodiment, the device control method further includes:

[0115] generating a control instruction in response to a key operation on the electronic device;

[0116] or,

[0117] generating a control instruction in response to a voice or gesture instruction directed to the display device;

[0118] or,

[0119] When the distance between the electronic device and the display device meets a preset distance condition, a control instruction is generated; wherein different display devices correspond to different preset distance conditions.

[0120] In an embodiment of the present disclosure, responding to a key operation on an electronic device includes: single-clicking or double-clicking a physical key such as a power key or a volume key of the electronic device to generate a control instruction.

[0121] The above-mentioned response to the voice instruction pointing to the display device includes: voice prompts, such as voice pointing to the display screen.

[0122] The voice prompt can be either direct or indirect. For example, when the voice prompt is direct, the user may directly send a voice to the electronic device, and the electronic device generates a control instruction after receiving the voice. When the voice prompt is indirect, the user may control another electronic device to send a voice, and the electronic device generates a control instruction after receiving the voice sent by the other electronic device. This embodiment of the present disclosure does not limit this.

[0123] The above-mentioned response to the gesture instruction pointing to the display device includes: a gesture operation acting on the display screen of the electronic device, such as sliding the display screen of the electronic device with three fingers, etc., to generate a control instruction.

[0124] When the distance between the electronic device and the display device satisfies a preset distance condition, generating the control instruction includes: generating the control instruction when the distance between the electronic device and the display device is less than or equal to a preset distance threshold.

[0125] It should be noted that the preset distance threshold may be set according to the type of display device, the size of the display screen of the display device, or a user-defined setting, and the embodiment of the present disclosure does not limit this.

[0126] Among them, when the preset distance threshold is set according to the type of display device, the preset distance threshold for the display device being a TV may be different from the preset distance threshold for the display device being a notebook; when the preset distance threshold is set according to the size of the display screen of the display device, the larger the size of the display screen, the larger the preset distance threshold, or the smaller the size of the display screen, the larger the preset distance threshold.

[0127] In this way, when the electronic device controls the display position of the pointer in the display device, it can better fit the area of ​​the display screen of the display device or better conform to the user's usage habits, thereby more conveniently adjusting the display position of the pointer in the display device.

[0128] In the embodiments of the present disclosure, control instructions are generated in different ways to control the display position of the pointer on the display device, which can improve the flexibility of the interaction between the electronic device and the display device.

[0129] In one embodiment, the device control method further includes:

[0130] The display device is connected via short-range wireless communication; wherein the short-range wireless communication includes Bluetooth communication or Star Flash communication.

[0131] In the disclosed embodiment, Bluetooth is used for pairing and connecting electronic devices and display devices. After the electronic devices and display devices are paired via Bluetooth, subsequent communication connections do not require confirmation each time. Star Flash communication is a new wireless short-range communication standard. Existing wireless short-range communication can no longer meet the requirements of connecting electronic devices and display devices in a local area in terms of latency, reliability, synchronization accuracy, and security. Therefore, electronic devices connected to display devices based on Star Flash communication have the advantages of lower power consumption, faster speed, lower latency, more stable connection, wider coverage, and larger networking.

[0132] It should be noted that short-range wireless communications can also include ultra-wideband (UWB). UWB is a wireless carrier communication with the advantages of low system complexity, low power spectrum density of transmitted signals, insensitivity to channel fading, low interception capability, and high positioning accuracy. It is suitable for high-speed wireless access of electronic devices and display devices in dense multipath places such as indoors.

[0133] In the embodiment of the present disclosure, the electronic device and the display device are connected via short-range wireless communication, which can improve the convenience of data transmission between the electronic device and the display device and reduce the power consumption of data transmission between the electronic device and the display device.

[0134] In one embodiment, obtaining motion parameters of an electronic device includes:

[0135] In response to a calibration instruction for the electronic device, obtaining calibration parameters through an ultra-wideband module of the electronic device;

[0136] calibrating a motion sensor of the electronic device based on the calibration parameters;

[0137] The motion parameters of the electronic device are detected based on the calibrated motion sensor.

[0138] In the disclosed embodiment, the calibration parameters include the position of the electronic device and the distance and angle between the electronic device and the display device. The ultra-wideband module can use a timestamp difference method to calculate the time of flight of electromagnetic waves between the electronic device and the display device, thereby calculating the distance and angle between the electronic device and the display device.

[0139] It should be noted that both the electronic device and the display device are provided with an ultra-wideband module. The electronic device is connected to the display device based on the ultra-wideband module, and the distance between the electronic device and the display device is calculated based on the timestamp sent by the electronic device.

[0140] For example, the time of flight is calculated based on the timestamp sent by the electronic device to the display device and the timestamp received by the display device. The time of flight is the difference between the sent timestamp and the received timestamp. The distance from the electronic device to the display device is calculated as the product of half the speed of light and the time of flight. UWB ranging can also use two-way ranging and bilateral two-way ranging, which are not limited in the present embodiment.

[0141] In the disclosed embodiments, motion sensors (such as accelerometers and gyroscopes) may generate errors during operation due to the influence of interference torques. These errors accumulate over time, reducing the accuracy of motion parameter acquisition for electronic devices. Therefore, to compensate for these errors, the motion sensors must be calibrated.

[0142] Exemplarily, when the electronic device detects that the electronic device is in a stationary state, the first motion parameter of the electronic device is obtained through the motion sensor, the distance and angle between the electronic device and the display device are obtained based on UWB, and the first motion parameter is calibrated based on the distance and angle between the electronic device and the display device, i.e., the calibration parameter.

[0143] In the embodiment of the present disclosure, by detecting the motion parameters of the electronic device based on the calibrated motion sensor, more accurate motion parameters of the electronic device can be obtained, and the display position of the pointer in the display device can be adjusted more accurately.

[0144] In one embodiment, the device control method further includes:

[0145] Obtaining an initial operating frequency sent by a cloud server connected to the electronic device;

[0146] Control the electronic device to switch from the initial operating frequency to the target operating frequency.

[0147] In the embodiment of the present disclosure, the electronic device may also be connected to a cloud server, and the electronic device obtains an initial operating frequency sent by the cloud server, and controls the display device with the initial operating frequency.

[0148] It is understood that the initial operating frequency of the electronic device controlling the display device may be different depending on the display screen area of ​​the display device. For example, the initial operating frequency of the electronic device may be 20 Hz, 30 Hz, or 50 Hz, etc., which is not limited in the embodiments of the present disclosure.

[0149] In this way, sending the initial operating frequency based on the cloud server can reduce the time it takes for the electronic device to obtain the initial operating frequency based on the motion parameters.

[0150] In the embodiment of the present disclosure, after the target operating frequency of the electronic device is determined, the initial operating frequency can be switched to the target operating frequency, and the display device connected to the electronic device can be controlled based on the target operating frequency.

[0151] It should be noted that when the target operating frequency is the same as the initial operating frequency, there is no need to switch the operating frequency of the electronic device, and the electronic device still operates at the initial operating frequency; when the target operating frequency is different from the initial operating frequency, it is necessary to switch the operating frequency of the electronic device from the initial operating frequency to the target operating frequency, and the electronic device operates at the target operating frequency.

[0152] In the embodiment of the present disclosure, the electronic device can receive the initial operating frequency sent by the cloud server and control the display device with the initial operating frequency, thereby improving the efficiency of the electronic device in controlling the display device. The target operating frequency can be switched based on the initial operating frequency, and the frequency of the electronic device controlling the display device can be flexibly adjusted to reduce the power consumption of the electronic device in controlling the display device.

[0153] To better understand the device control method in one or more of the above embodiments, the following examples are provided for reference:

[0154] Figure 3FIG. 1 is a structural diagram showing the communication interaction between an electronic device and a display device according to an exemplary embodiment. Figure 3 As shown, the electronic device includes a sensor processing chip and a communication module, such as Bluetooth, Star Flash, and UWB; the display device also includes a communication module, such as Bluetooth, Star Flash, and UWB. Both the electronic device and the display device can connect to a cloud server.

[0155] In the disclosed embodiments, when the distance between an electronic device and a display device is less than a preset distance, the electronic device can pair with the display device via Bluetooth. After pairing is complete, the electronic device generates a control instruction. Here, a control instruction represents the electronic device controlling the display device. The electronic device controlling the display device can include controlling the movement of a pointer on a display screen of the display device, or controlling the display device to perform click operations, scroll or turn pages, and so on.

[0156] After the electronic device is paired with the display device, the initial operating frequency sent by the cloud server to the electronic device can be received, so that the electronic device can control the display device using the initial operating frequency.

[0157] During the movement of the electronic device, the electronic device obtains an acceleration value of the electronic device through an accelerometer and an angular velocity value of the electronic device through a gyroscope, and then calculates the movement speed of the electronic device based on the acceleration value or the angular velocity value. If the movement speed of the electronic device is greater than a preset parameter threshold, the target operating frequency of the electronic device is determined to be a first preset frequency; if the movement speed of the electronic device is less than or equal to the preset parameter threshold, the target operating frequency of the electronic device is determined to be a second preset frequency. The first preset frequency is greater than the second preset frequency.

[0158] It should be noted that after determining the target operating frequency of the electronic device, the target operating frequency is compared with the initial operating frequency. If the target operating frequency is different from the initial operating frequency, the operating frequency of the electronic device is adjusted, switching the operating frequency of the electronic device from the initial operating frequency to the target operating frequency.

[0159] After the operating frequency of the electronic device is switched to the target operating frequency, the electronic device can control the display position of the pointer in the display device connected to the electronic device based on the target operating frequency, including: running a coordinate conversion algorithm at the service layer of the sensor main processing chip of the electronic device to convert the motion parameters of the electronic device, and obtaining the coordinates of the pointer in the display device after it moves on the display screen of the display device; the electronic device transmits the coordinates of the pointer after movement to the display device through Bluetooth communication or Star Flash communication at the target operating frequency to adjust the display device.

[0160] In the embodiment of the present disclosure, the motion parameters of the electronic device are obtained in response to a control instruction, and based on the motion parameters of the electronic device, the target operating frequency of the electronic device is determined, and then based on the target operating frequency, the display device connected to the electronic device is controlled. It can be seen that, on the one hand, the embodiment of the present disclosure can control the display device through the electronic device, thereby improving the convenience of the user in controlling the display device; on the other hand, compared with using a fixed operating frequency to control the display device, the embodiment of the present disclosure can flexibly select different target operating frequencies to control the display device according to the motion parameters of the electronic device, thereby not only making the movement of the electronic device and the display of the display device more synchronized, but also realizing dynamic adjustment of the operating frequency of the electronic device to reduce the power consumption of the electronic device in controlling the display device.

[0161] In one embodiment, Figure 4 FIG. 1 is a schematic diagram showing the interaction between an electronic device, a display device and a cloud server according to an exemplary embodiment. Figure 3 and Figure 4 As shown, the display device includes configuration parameters, which are used to initialize the display device. The cloud server can send configuration parameters, such as the size, resolution, and refresh rate of the display device, to display device 1 and display device 2. Display device 1 and display device 2 can be initialized based on the configuration parameters sent by the cloud server.

[0162] In this way, when the electronic device switches from display device 1 to display device 2, the display device does not need to perform initialization operations, thereby improving the initialization speed of the display device. This not only improves the smoothness of switching when the electronic device switches from controlling display device 1 to controlling display device 2, but also enables one electronic device to control the display position of the pointer of multiple display devices.

[0173] In one embodiment, the electronic device further comprises:

[0174] The communication connection module is configured to connect to the display device via short-range wireless communication; wherein the short-range wireless communication includes Bluetooth communication or Star Flash communication.
