     DETAILED DESCRIPTION 
     Description will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations in the following description of exemplary embodiments do not represent all implementations consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with aspects related to the present disclosure as detailed in the appended claims. 
     In a process of realizing interconnection and intercommunication of devices, users are often required to manually operate to control functions among devices. 
     Various embodiments of the present disclosure can realize smart interconnections and intercommunications among various devices. 
     A function control method provided by some embodiments of the present disclosure can be applied to interactive control scenarios between IoT devices. The IoT devices can be smart terminals or smart home devices. 
     In the function control method provided by some embodiments of the present disclosure, the smart space semantic map may be a pre-established map, in which specific locations of all devices in a predetermined space (for example, a house with multiple rooms) and location relationship between different devices can be set. 
     In the function control method provided by some embodiments of the present disclosure, the device that performs function control and interaction may be configured with a smart space semantic map. It can be understood that specific locations of all devices in a predetermined space (for example, a house with multiple rooms) and location relationship between different devices are set in the smart space semantic map. Taking the predetermined space being a house with multiple rooms as an example, location information of any device can be obtained through the map, where the location information may include rooms, locations in the rooms, and so on. In the map, the location of any device can be used to determine the location of other devices based on the location relationship between different devices. 
     In a function control method provided by some embodiments of the present disclosure, the location of a device is determined through the smart space semantic map, the device executing the corresponding function is determined in the smart space semantic map by determining the location of the device, so as to control the device to execute the corresponding function. 
     In some embodiments of the present disclosure, for the convenience of description, the device that performs function control over other devices is called the first device, the device that executes the corresponding function is called the second device, and the function that the second device is triggered to execute is called the first function, and the location of the first device in the smart space semantic map is called the first location. 
       FIG. 1  is a flowchart showing a function control method according to some embodiments, and as shown in  FIG. 1 , the function control method can be applied to a first device and includes the following steps. 
     In step S 11 , a first location of the first device in the smart space semantic map is determined. 
     In some embodiments of the present disclosure, the first device is configured with a smart space semantic map, so the first location can be understood as the location of the first device in the smart space semantic map. The first location of the first device in the smart space semantic map may be determined by a user device based on the information included in the smart space semantic map. For example, the first device can determine the first location based on communication with other devices, or the first device can determine the first location by combining the acquired surrounding environment information with the smart space semantic map. 
     In step S 12 , a second device is determined in the smart space semantic map based on the first location, and the second device has a capability of executing a first function. 
     In some embodiments of the present disclosure, the smart space semantic map includes devices that need to be controlled by the first device, and thus in the embodiments of the present disclosure, the second device capable of executing the first function can be determined in the smart space semantic map. It can be understood that there may be one or more devices capable of executing the first function in the smart space semantic map. 
     In step S 13 , a predetermined action is executed, to cause the second device to execute the first function. 
     In some embodiments of the present disclosure, the predetermined action may be understood as an operation instruction or an operation that triggers the second device to execute the first function. 
     The function control method applied to the first device in some embodiments of the present disclosure determines the second device to execute function operation control based on the location of the first device in the smart space semantic map, and executes a predetermined action to cause the second device to execute the corresponding function, which can realize smart interactive control of the function control between the first device and the second device without selecting the second device on the first device by the user. 
     In some embodiments of the present disclosure, the function control method involved in the above-mentioned embodiments will be described below in combination with practical applications. 
     In some embodiments of the present disclosure, the first function executed by the second device is first described. The first function may be a function that can be executed by the first device, or a function that cannot be executed by the first device but can be executed by the second device. For example, when the first device is a mobile phone and the second device is a TV, the first function is a video playback function, and both the mobile phone and the TV can execute the video playback function. For another example, when the first device is a mobile phone and the second device is a TV, the first function is a screen projection function, the mobile phone has the function of triggering to execute screen projection but does not have the function of receiving a projection screen instruction for playback, but the TV has the function of receiving and executing a projection screen playback instruction. 
     The embodiments of the present disclosure do not specifically limit the first function executed when the function control is performed between the first devices and/or the second devices, for example, the first function may be one of the screen projection function, the music playback function, and the video playback function, or a combination thereof. 
     In some embodiments of the present disclosure, implementation process of determining the first location of the first device in the smart space semantic map will be described below. 
     In some embodiments of the present disclosure, to determine the first location of the first device in the semantic map of the smart space may be, on the one hand, determined in advance the first location of the first device in the smart space semantic map, prior to executing the first function in response to the first device being triggered, and may be, on the other hand, determining the first location of the first device in the smart space semantic map in response to the first device being triggered to execute the first function. 
     In response to the first device being triggered to execute the first function may be in response to a terminal network environment switching to trigger to execute the first function. For example, if the first device is a mobile phone, it may be that when the user enters home, the mobile phone connects to the home hotspot to trigger execution of the first function. For another example, it may also be that the user performs a functional operation on the mobile phone to trigger execution of the first function, such as triggering execution of a screen projection function or triggering a function playback of music or video, etc. 
     In an implementation of some embodiments of the present disclosure, determining the first location of the first device in the smart space semantic map can be obtained through visual information. The visual information can be understood as image information obtained by image acquisition by an image acquisition device such as a camera. 
     In one mode, the first device may pre-store image information representing different region locations in the smart space semantic map, for example, it may be multiple sample images. The image information representing different region locations in the smart space semantic map may be pre-stored in a memory device of the first device, or pre-stored in a cloud server associated with the first device. When determining the first location of the first device in the smart space semantic map, the first device can acquire a current surrounding environment image and perform feature matching with the pre-stored sample image based on the acquired image to determine the first location of the first device in the smart space semantic map. 
     For the convenience of description, in some embodiments of the present disclosure, the image acquired by the first device may be referred to as the first image. 
       FIG. 2  is a flowchart showing a method for determining a first location of a first device in a smart space semantic map according to some embodiments. 
     In step S 21 , a first image is acquired. 
     In some embodiments of the present disclosure, the first device may capture the first image by an image capture device provided in the first device itself, or may obtain the first image by other methods. For example, the mobile phone can be used as the first device, and the first image is obtained by taking a photo by any camera of the mobile phone. The first device may also obtain the first image through assisting of other devices. For example, the first device may communicate with a device having an image capture function, such as a surveillance camera in the room, to obtain the first image captured by other devices. 
     It can be understood that the first image acquired in some embodiments of the present disclosure is an image captured by the first device at the current location and used to match the sample image at the corresponding location in the smart space semantic map. 
     For example, as shown in  FIG. 10 , the smart space semantic map includes a living room, a bedroom (second bedroom, master bedroom), a bathroom, a study room and other rooms, and stores sample images (images of a bed, a sofa, a white wall, etc.) corresponding to the living room, the bedroom (second bedroom, master bedroom), the bathroom, the study room and other rooms. If the current location of the first device is the living room, the acquired first image should be a sample image corresponding to the living room in the smart space semantic map, such as an image of a white wall, an image of a sofa, etc. 
     In step S 22 , a first sample image is determined from multiple pre-stored sample images. 
     In some embodiments of the present disclosure, the first sample image may be understood as a sample image whose features in the smart space semantic map match the features of the first image. For example, if the acquired first image is an image including a sofa, the first sample image may be understood as a sofa image used to represent the living room in the smart semantic map. 
     In some possible implementations, pixel distribution of the first image and the sample image can be analyzed through, for example, an image feature matching algorithm, and the sample image with the highest similarity is determined as the first sample image. 
     In step S 23 , a first location of the first device in the smart space semantic map is determined based on a region location represented by the first sample image. 
     In some embodiments of the present disclosure, the pre-stored sample image represents a region location. For example, the region location represented by a sample image that includes image information such as white wall and bed in the bedroom is the bedroom. The region location represented by the sample image including image information such as white wall, sofa, TV, and coffee table in the living room is the living room. 
     After the first sample image matching the first image feature is determined in some embodiments of the present disclosure, the location of the first device in the smart space semantic map can be determined based on the region location represented by the first sample image. For example, if the acquired first image is an image including a sofa, and the matched first sample image is a sofa image representing a living room, it can be determined that the first location of the first device in the smart space semantic map is the living room. 
     In some embodiments of the present disclosure, the number of first sample image whose feature matches the feature of the first image may be one or more. The region location represented by the first sample image that matches the first image feature may be one or more. For example, white wall is included in regions such as the living room and bedroom. If the first sample image is an image including a white wall, then the region location represented by the first sample image includes a bedroom and a living room, in this case, it will be necessary to further determine the first location in combination with other sample images. 
       FIG. 3  is a flowchart showing a method for determining a first location of a first device in a smart space semantic map according to some embodiments. 
     In step S 231 , in response to that the region location represented by the first sample image is one, the region location represented by the first sample image is determined as the first location of the first device in the smart space semantic map. 
     The region location represented by the first sample image is one, and the region location can be directly determined as the first location of the first device in the smart space semantic map. 
     In step S 232 , in response to that the region location represented by the first sample image is multiple, a second image is acquired. 
     When multiple region locations are represented by the first sample image, it means that the first location cannot be determined accurately from the image feature of the first image. In some embodiments of the present disclosure, in the case where there are multiple region locations represented by the first sample image, other images different from the first image can be continuously acquired, which is referred to as the second image below, and the first location is further determined based on the second image. 
     In step S 233 , a second sample image is determined from multiple pre-stored sample images, and the first location of the first device in the smart space semantic map is determined based on a region location represented by the second sample image. 
     The second sample image is a sample image whose image features match the features of the second image in the sample image of the smart space semantic map, and the second sample image is different from the first sample image. 
     In some embodiments of the present disclosure, the second image is an image that is different from the first image in terms of shooting orientation. By shooting the first image and the second image in different orientations at a shooting point, the unique region location commonly represented by the matched sample images is filtered out, as the first device&#39;s first location in the smart space semantic map. For example, the first image can be taken by the front camera of the mobile phone, and when the first location of the first device in the smart space semantic map cannot be determined from the first image, the rear camera of the mobile phone is controlled to turn on to take the second image. The first image and the second image obtained are compared with the respective sample images, and the common unique solution of the region location represented by the first image and the second image is used as the first location of the first device in the smart space semantic map. 
     In another implementation of some embodiments of the present disclosure, the first location of the first device in the smart space semantic map can be obtained through acoustic information and/or microwave information. The acoustic information can be understood as a sound signal sent by the first device or the user, and can also be a sound wave signal sent by the first device. According to the sound signal or sound wave signal, the first location of the first device in the smart space semantic map is determined in the manner of sound source positioning or sound wave positioning. The microwave information can be understood as a wireless signal transmitted by a router, etc., and can also be understood as a pulse positioning signal transmitted by a first device including a UWB module. 
     In some embodiments of the present disclosure, when the first location of the first device in the smart space semantic map is determined based on acoustic information and/or microwave information, other devices (hereinafter referred to as the third device) may assist the first device in determining the first location. 
       FIG. 4  is a flowchart showing a method for determining a first location based on a third device in a smart space semantic map according to some embodiments. 
     In step S 31 , location information of the first device sent by a third device is acquired. 
     In some embodiments of the present disclosure, the third device may determine location information in response to receiving a location determining instruction triggered at the location of the first device, and the location information is sent to the first device. The first device receives the location information sent by the third device. The location determining instruction that triggers the third device to determine the location information at the location of the first device may include a voice instruction and/or a microwave instruction. For example, the location determining instruction may be playback sound of music, video, etc. played on the first device, or the location determining instruction may also be a voice control instruction issued by a user using the first device, or a sound wave signal emitted by the first device, or the microwave signal emitted by the first device. 
     In some embodiments of the present disclosure, the location information determined by the third device may be time stamp information of receiving the location determining instruction. 
     In step S 32 , the first location of the first device in the smart space semantic map is determined based on the location information. 
     When the first location of the first device in the smart space semantic map is determined based on the location information in some embodiments of the present disclosure, the first location of the first device in the smart space semantic map may be determined based on the speed of sound and the propagation timestamp, or the propagation speed of the microwave and the timestamp. 
     In some embodiments of the present disclosure, the first location of the first device in the smart space semantic map can be determined through the above-mentioned visual information, acoustic information, and microwave information, and then the second location that needs to perform function control can be further determined based on the first location. 
       FIG. 5  is a flowchart showing a method for determining a second device based on a first location in a smart space semantic map according to some embodiments. 
     In step S 41 , a sub-region corresponding to the first location is determined. 
     In some embodiments of the present disclosure, the smart space semantic map includes sub-regions for distinguishing multiple different spatial locations, thus, when determining the sub-regions corresponding to the first location, on the one hand, the sub-region to which the first location belongs can be determined as the sub-region corresponding to the first location, and on the other hand, other sub-regions different from the sub-region to which the first location belongs may also be determined as the sub-region corresponding to the first location. 
     In an example, in some embodiments of the present disclosure, when the first device determines that there is a second device that needs to be controlled in the sub-region corresponding to the first location, the sub-region to which the first location belongs can be directly determined as the sub-region corresponding to the first location. In some embodiments of the present disclosure, when the first device determines that there is no second device that needs to be controlled in the sub-region corresponding to the first location, other sub-regions different from the sub-region to which the first location belongs may be determined as the sub-region to which first location corresponds. For example, as shown in  FIG. 6 , if the first device needs to execute a humidification function, the room region where the humidifier W is located can be selected as the sub-region corresponding to the first location. If the first device needs to execute the function of playing music, the room region where the speaker U 1  and the speaker U 2  are located can be selected as the sub-region corresponding to the first location. 
     In step S 42   a , in response to the presence of one target operating device having the capability of executing the first function in the sub-region corresponding to the first location, the target operating device is determined as the second device. 
     In some embodiments of the present disclosure, in response to presence of a target operating device capable of executing the first function in the corresponding sub-region of the first location, the target operating device is used as the second device. For example, as shown in  FIG. 7 , when the terminal in the living room needs to execute the function of playing music and there is only one speaker in the living room, the speaker in the living room is directly determined as the second device to play music. 
     In step S 42   b , in response to the presence of multiple target operating devices having the capability of executing the first function in the sub-region corresponding to the first location, a second location in the sub-region is determined based on the first location and a target operation of the first device, and a target operating device at the second location is determined as the second device. 
     In some embodiments of the present disclosure, when determining the second device, the granularity of the location may be determined based on the functional operation that needs to be executed and the device that needs to be controlled. 
     In an example, if there are multiple target operating devices in the current region, and the first device only needs to determine one second device, the unique second device can be determined by narrowing the sub-region corresponding to the first location. For example, as shown in  FIG. 8 , when the terminal in the living room needs to execute the screen projection function, and there are two TVs A and B in the living room, TV B being closer to the first device can be determined from TV A and TV B as the second device for projection by narrowing the sub-regions. 
     In some embodiments of the present disclosure, when determining the second device for control, the second location may be determined in the sub-region based on the first location and the target operation of the first device. 
       FIG. 9  is a flowchart showing a method for determining a second location in a smart space semantic map based on a movement trajectory of a first device according to some embodiments. 
     In step S 51 , in response to detecting that a movement trajectory of the first device has changed, a changed trajectory direction of the first device is determined. 
     In step S 52 , the location where the target operation device is set and in the changed trajectory direction of the first device as determined in the smart space semantic map is determined as the second location. 
     In some embodiments, the change in the trajectory of the first device may include an operation of the first device pointing to the target operating device. When the operation of the first device pointing to the target operating device is detected, the orientation of the first device relative to the location of the first device on the pre-established map after orientation change can be determined. In an example, the first device is currently located three meters southwest of the second device, and the first device is waved along the southwest direction at the current location to point to the target operating device. Combining the location of the second device on the smart space semantic map and the location relationship information of respective devices in the smart space semantic map, the second device can determine the target operating device at the location of the orientation corresponding to the location in the smart space semantic map. 
     In another embodiment, the change in the trajectory of the first device may also include an operation of the first device being moved and approaching the target operating device. In an example, when it is detected that the first device is moved and approached to the target operation, the orientation of the first device relative to the location of the first device in the pre-established map after orientation change can be determined. In an example, the first device is currently located three meters southwest of the second device, and the first device is carried by the user to approach to the target operating device along the southwest direction at the current location. In the application process, the target operation device can be determined by combining the location of the second device in the smart space semantic map and the target operation of the first device. 
     In the function control method provided by some embodiments of the present disclosure, when determining the second device, on the one hand, in the case of rough granularity, such as projecting to the only TV in the living room, the second device (TV) that the user intends to control can be determined directly through the user&#39;s current general location information (the living room to which the first location corresponds). On the other hand, when the granularity requirement is relatively high, when the user device points to the device that is to be connected to, it also needs to track the movement trajectory of the user device (for example, sensors such as gyroscopes etc.). For example, in  FIG. 10 , the first location of the user&#39;s first device is the location P 2  in the living room, it is determined that there are multiple second devices in the living room (represented by the circle in the figure), and then the user&#39;s pointing direction A can be known through movement of the user. Through the location P 2  and the pointing direction A, the second device that the user intends to control can be determined, and the device that the user is trying to control can be retrieved from the smart space semantic map. 
     Further, the number of the second device executing the first function in some embodiments of the present disclosure may be one or multiple. 
     In some possible implementations, if only one second device is required to execute the first function, the unique second device can be determined. For example, as shown in  FIG. 7 , when the mobile phone needs to execute the function of playing music, a speaker is determined to play audio. 
     In another example, when the first function to be executed requires multiple second devices, multiple second devices can be determined to jointly execute the first function. For example, as shown in  FIG. 11 , when the mobile phone needs to execute the function of playing music, four speakers can be controlled concurrently to play music. 
     In another example, when multiple second devices are required to execute the first function, multiple second devices may execute the same function. As shown in  FIG. 11 , four speakers play music together. When the executed first function requires multiple second devices, the multiple second devices may execute multiple different functions. For example, as shown in  FIG. 12 , the TV is equipped with components that can play audio, and there are two other external speakers in the region. In an implementation of embodiments of the present disclosure, when the mobile phone needs to execute a video playback function, it can control the TV to play images and audio at the same time. It can also control the TV to play images and control the external speakers to play audio when the mobile phone needs to execute the video playback function. When multiple first functions need to be executed, multiple second devices may be determined to execute the first function. For example, when the mobile phone needs to execute the “K song” function, the TV is controlled to play pictures, the smart watch is controlled to play lyrics and subtitles, and the external speakers are controlled to play audio. 
     Based on the same inventive concept, the present disclosure further provides a function control apparatus. 
     It may be understood that, in order to achieve the above functions, the function control apparatus provided by some embodiments of the present disclosure includes a hardware structure and/or a software module corresponding to each function. With reference to the units and algorithm steps of each example disclosed in some embodiments of the present disclosure, some embodiments of the present disclosure may be implemented in the form of hardware or a combination of hardware and computer software. Whether a certain function is performed by hardware or computer software-driven hardware depends on the specific application and design constraints of the technical solutions. Those skilled in the art may use different methods to implement the described functions for each specific application, but such implementation should not be considered to go beyond the scope of the technical solutions of the embodiments of the present disclosure. 
       FIG. 13  is a block diagram showing a function control apparatus according to some embodiments. Referring to  FIG. 13 , the device  100  includes a determining unit  101  and an executing unit  102 .
