[0015] If the new device distance and the new device angle do not change, it is determined that the preset trigger condition is met.

[0016] Exemplarily, before the step of receiving a pulse signal sent by a second device based on the first antenna to obtain a first received signal and receiving the pulse signal based on the second antenna to obtain a second received signal, the step includes:

[0017] Upon detecting a preset operation, controlling the first device to enter a device linkage mode;

[0018] The steps of receiving the pulse signal sent by the second device based on the first antenna to obtain a first received signal and receiving the pulse signal based on the second antenna to obtain a second received signal are performed only when the first device is in the device linkage mode.

[0019] Exemplarily, the first device is an AR device, the second device is a smart wearable device, and the data interaction with the second device based on the Bluetooth connection includes:

[0020] Based on the Bluetooth connection, receiving user data sent by the smart wearable device;

[0021] The user data is displayed so that the user can obtain the user data collected by the smart wearable device through the AR device.

[0022] In addition, to achieve the above-mentioned purpose, the present application also provides a data interaction method, which is applied to a second device, wherein the second device at least includes a second UWB module, and the second UWB module includes a third antenna. The data interaction method includes:

[0023] Based on the third antenna, a pulse signal is sent to the first device, so that the first device receives the pulse signal and determines, based on the pulse signal, whether the relative position relationship between the first device and the second device meets a preset trigger condition;

[0024] After the first device determines that the relative position relationship meets the preset trigger condition, establishing a Bluetooth connection with the first device;

[0034] Compared with the prior art, since if data interaction is required between devices, the user needs to operate the device to establish a Bluetooth connection between the two devices, resulting in a cumbersome process for data interaction between devices, the present application interacts with the second device by determining that the relative position relationship between the first device and the second device in time meets a preset trigger condition based on at least the first received signal and the second received signal, wherein the first received signal is received by the first antenna in the first device and the second received signal is received by the second antenna in the first device. Thus, when the first device and the second device need to interact with data, the two devices can automatically establish a Bluetooth connection by themselves and interact with data through the Bluetooth connection. The entire process does not require user participation, that is, the user does not need to perform device connection operations, thereby simplifying the process of data interaction between devices.

[0040] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0041] This application provides a data interaction method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the data interaction method of the present application.

[0042] The embodiment of the present application provides an embodiment of the data interaction method. It should be noted that although the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than here. The data interaction method can be applied to a first device, the first device at least includes a first UWB (Ultra Wide Band) module, and the first UWB module includes at least a first antenna and a second antenna. It can be understood that the first device is a UWB device.

[0043] For ease of description, the following description of each step of the data interaction method is omitted. The data interaction method includes the following steps:

[0044] Step S10: receiving a pulse signal sent by a second device based on the first antenna to obtain a first received signal, and receiving the pulse signal based on the second antenna to obtain a second received signal.

[0045] The first antenna and the second antenna are both antennas in the first UWB module, that is, the first device adopts a dual-antenna design. In addition, the first device can also be a three-antenna design, a four-antenna design, etc., and accordingly, each antenna can independently receive the pulse signal to obtain a corresponding received signal.

[0046] Exemplarily, when the first device is a device for convenient data output, the first device includes AR devices, VR devices, smart TVs, smart speakers, etc., and the second device is a device for providing data, including smart wearable devices (smart watches, smart bracelets, etc.), smart speakers, smart TVs, etc.; when the second device is a device for convenient data output, the second device includes AR devices, VR devices, smart TVs, smart speakers, etc., and the first device is a device for providing data, including smart wearable devices (smart watches, smart bracelets, etc.), smart speakers, smart TVs, etc. This embodiment does not limit what kind of device the first device is, nor does it limit what kind of device the second device is. It can be understood that when the first device is a device for providing data, there is a need to display the data to the user through the second device; when the second device is a device for providing data, there is a need to display the data to the user through the first device.

[0047] Among them, the pulse signal is expressed as a curve with countless breakpoints on the plane coordinates, that is, it has some points periodically, and the limit of the point does not exist. The pulse signal includes rectangular waves, sawtooth waves, sharp pulses and step waves.

[0048] Exemplarily, before the step of receiving a pulse signal sent by a second device based on the first antenna to obtain a first received signal and receiving the pulse signal based on the second antenna to obtain a second received signal, the step includes:

[0049] Step a, detecting a preset operation, controlling the first device to enter a device linkage mode; when the first device is in the device linkage mode, executing the step of receiving a pulse signal sent by the second device based on the first antenna to obtain a first received signal, and receiving the pulse signal based on the second antenna to obtain a second received signal.

[0050] Exemplarily, the preset operation includes button operation, screen touch operation or voice operation, etc.

[0051] After the first device enters the device linkage mode, it can be determined that the user has a need to make the first device and the second device interact with each other. At this time, the first device receives the pulse signal sent by the second device. When the first device does not enter the device linkage mode, the first device does not receive the pulse signal, that is, the pulse signal sent by the second device is not for the first device, but for other devices, that is, the first device does not need to interact with the second device. It can be understood that by setting the device linkage mode, the first device avoids the wrong response to the pulse signal.

[0052] Step S20: Determine whether the relative position relationship between the first device and the second device meets a preset trigger condition based at least on the first received signal and the second received signal.

[0053] The preset trigger condition needs to meet at least two conditions, one of which is that the distance between the two devices meets the distance condition, and the other is that the angle between the two devices meets the angle condition. The distance and the angle are both calculated by the first received signal. When both conditions are met, it is determined that the relative position relationship meets the preset trigger condition; when at least one condition is not met, it is determined that the relative position relationship does not meet the preset trigger condition.

[0054] Exemplarily, the relative position relationship includes a device distance and a device angle, and determining whether the relative position relationship between the first device and the second device satisfies a preset trigger condition based at least on the first received signal and the second received signal includes:

[0055] Step b: calculating a device distance between the first device and the second device, and calculating a device angle between the first device and the second device based at least on the first received signal and the second received signal.

[0056] Exemplarily, the device distance may be calculated by TW-TOF (Two Way-Time Of Flight) or TOF (Time Of Flight).

[0057] Among them, when the device distance is calculated by TW-TOF: the third antenna transmits a pulse signal at the Ta1 moment of the first timestamp (the timestamp generated by the second device), which is received by the first antenna at the Tb1 moment of the second timestamp (the timestamp generated by the first device); the first antenna responds to the pulse signal, transmits a response signal at the Tb2 moment of the second timestamp, which is received by the third antenna at the Ta2 moment of the first timestamp, thereby calculating the first distance S=c×[(Ta2-Ta1)-(Tb2-Tb1)] between the third antenna and the first antenna, where c is the speed of light. It can be understood that the calculation process of the second distance between the third antenna and the second antenna is basically the same as the calculation process of the first distance between the third antenna and the first antenna, and will not be repeated here. For the device distance, the device distance can be the first distance, the second distance, or the average of the first distance and the second distance. It can be understood that since the first antenna and the second antenna are both in the first device, the difference between the first distance and the second distance is small, for example, 1 cm, and the first distance or the second distance represents the distance between the first device and the second device, which is the distance from the user's head (AR device worn on the head) to the wrist (smart wearable device worn on the wrist), which is generally about 50 cm. Therefore, the difference between the first distance and the second distance is much smaller than the first distance or the second distance, so that the first distance or the second distance can be directly used as the distance between the first device and the second device.

[0058] Among them, when the device distance is calculated by TOF: calculate the first time difference TTOT between the time when the third antenna sends a pulse signal and the time when the response of the first antenna is received; and calculate the second time difference TTAT between the time when the first antenna receives the pulse signal and the time when the response is sent to the third antenna. Thus, the first distance S=c×(TTOT-TTAT) / 2 between the third antenna and the first antenna can be calculated, where c is the speed of light. Accordingly, the calculation process of the second distance between the third antenna and the second antenna (or other antennas in the first device when the first device is a three-antenna design or a four-antenna design, etc.) is basically the same as the calculation process of the first distance between the third antenna and the first antenna, and will not be repeated here. Similarly, the specific implementation method corresponding to the device distance being the first distance or the second distance, etc., is basically the same as the specific implementation method corresponding to the device distance being the first distance or the second distance, etc. when the device distance is calculated by TW-TOF, and will not be repeated here.

[0059] For example, Figure 2 is a schematic diagram of a measuring device angle, such as Figure 2As shown, 201 is the third antenna of the second device, which is used to transmit a pulse signal; 202 and 203 are the first antenna and the second antenna respectively; 204 is the device angle α to be calculated; 205 is the path difference p from the third antenna to the first antenna and the second antenna, which is calculated by the phase difference between the first received signal and the second received signal; 206 is the antenna distance d between the first antenna and the second antenna, which is a fixed value. It can be understood that there is an inverse trigonometric function relationship between the device angle α, the path difference p and the antenna distance d, that is, the device angle α can be calculated by the following formula:

[0060]

[0061] It should be noted that, for the first device with three or four antennas, the final device angle can be obtained by first calculating the device angle corresponding to the two antennas, and then calculating the average of all device angles. The specific implementation of the device angle corresponding to the two antennas is basically the same as the specific implementation of the device angle corresponding to the first antenna and the second antenna, and will not be repeated here.

[0062] Step c: if the device distance is less than or equal to the preset device distance, and the device angle is less than or equal to the preset device angle, it is determined that the preset trigger condition is met.

[0063] Exemplarily, the preset device distance and the preset device angle can be set as needed, and can be determined based on the actual conditions of the first device and the second device (for example, the first device is an AR device and the second device is a smart bracelet, or the first device is a smart TV and the second device is a smart speaker).

[0064] For example, the first device is an AR device or a VR device, and the second device is a smart wearable device; or the first device is a smart wearable device, and the second device is an AR device or a VR device. It can be understood that the AR device or VR device is worn on the user's head when in use, and the distance between it and the smart wearable device is related to the user's height. The smart wearable device is worn on the user's wrist, and the distance between it and the AR device or VR device is related to the user's arm length. Therefore, the preset device distance can be set by the user's height and the user's arm length. For example, after the user raises his wrist, the device distance is measured to be 50cm (related to the user's height and the user's arm length), then the preset device distance can be set to 50cm, and the device angle is measured to be 20 degrees, then the preset device angle can be set to 20 degrees.

[0065] For example, the first device is a smart TV and the second device is a smart speaker; or the first device is a smart speaker and the second device is a smart TV. It is understandable that generally, smart TVs are fixedly installed and used, while smart speakers can be moved and used. The preset device distance can be set as needed, for example, the preset device distance is 10cm, 20cm, etc.; accordingly, the preset device angle can be 10 degrees, 9 degrees, etc., which is specifically set for the purpose of user convenience.

[0066] For example, the first device is a smart wearable device and the second device is a smart TV; or the first device is a smart TV and the second device is a smart wearable device. It can be understood that generally, smart TVs are fixedly installed and used, and smart wearable devices are worn on the user's wrist, so smart wearable devices can be used mobile, similar to smart TVs and smart speakers, and the preset device distance can be set as needed. For example, the preset device distance is 10cm, 20cm, etc.; accordingly, the preset device angle can be 10 degrees, 9 degrees, etc., which is specifically set for the purpose of facilitating user use.

[0067] Exemplarily, if the device distance is less than or equal to a preset device distance, and the device angle is less than or equal to a preset device angle, determining that a preset trigger condition is met includes:

[0068] Step c1, if the device distance is less than or equal to the preset device distance, and the device angle is less than or equal to the preset device angle, then continuously receiving the pulse signal within a preset time;

[0069] Step c2, based on the continuously received pulse signal, calculate the new device distance and the new device angle; if the new device distance and the new device angle have not changed, determine that the preset trigger condition is met.

[0070] The purpose of continuously receiving the pulse signal within the preset time is to avoid erroneous device responses. Specifically, the purpose of determining that the new device distance and the new device angle have not changed is to ensure that the user maintains a posture and maintains it for a preset time. It can be understood that when the user maintains a posture and maintains it for a preset time, it indicates that the user has a need to enable the first device and the second device to interact with data. For example, the user wears an AR device on the head and a smart wearable device on the wrist, and the user raises his wrist and looks at the smart wearable device for a period of time (up to the preset time), it is determined that the user has a need to enable the AR device and the smart wearable device to interact with data.

[0071] Exemplarily, the preset time can be set as needed, such as 2s, 3s, etc.

[0072] It should be noted that the specific implementation of calculating the new device distance and the new device angle is basically the same as the specific implementation of calculating the device distance and the device angle mentioned above, and will not be repeated here.

[0073] Step S30: If the conditions are met, a Bluetooth connection is established with the second device, and data is exchanged with the second device based on the Bluetooth connection.

[0074] If not, continue to receive pulse signals until it is satisfied.

[0075] Exemplarily, the first device is an AR device, the second device is a smart wearable device, and the data interaction with the second device based on the Bluetooth connection includes:

[0076] Step d, receiving user data sent by the smart wearable device based on the Bluetooth connection;

[0077] Step e: displaying the user data so that the user can obtain the user data collected by the smart wearable device through the AR device.

[0078] Exemplarily, user data includes sports health data and / or application data, etc. It can be understood that since the display effect of AR devices is much better than that of smart wearable devices (small screen), displaying user data collected by smart wearable devices through AR devices is significantly improved compared to directly displaying user data through smart wearable devices.

[0079] It should be noted that if it is determined that the relative position relationship does not meet the preset trigger condition, the pulse signal sent by the second device continues to be received through the first antenna and the second antenna, or other antennas receive the pulse signal sent by the second device until it is determined that the relative position relationship meets the preset trigger condition.

[0080] It can be understood that when the first device is an AR device and the second device is a smart wearable device, the AR device includes at least a first antenna and a second antenna, and the smart wearable device includes a third antenna; when the first device is a smart wearable device and the second device is an AR device, the AR device includes at least a first antenna and a second antenna, and the AR device includes a third antenna.

[0081] Correspondingly, for the case where the first device and the second device are other devices, the difference between the case where the first device is an AR device and the second device is a smart wearable device is that the data when data interaction occurs between the devices is different and the way of outputting the data is different. For example, if the first device is a smart speaker and the second device is a smart TV, the smart speaker receives the audio data of the smart TV and outputs the audio data as sound; in another case, if the first device is an AR device and the second device is a smart TV, its data and corresponding output method are basically the same as the data and corresponding output method of the first device being an AR device and the second device being a smart wearable device; in another case, if the first device is an AR device and the second device is a smart speaker, its data and corresponding output method are basically the same as the data and corresponding output method of the first device being a smart speaker and the second device being a smart TV.

[0082] Compared with the prior art, since if data interaction is required between devices, the user needs to operate the device to establish a Bluetooth connection between the two devices, resulting in a cumbersome process for data interaction between devices, the present application interacts with the second device by determining that the relative position relationship between the first device and the second device in time meets a preset trigger condition based on at least the first received signal and the second received signal, wherein the first received signal is received by the first antenna in the first device and the second received signal is received by the second antenna in the first device. Thus, when the first device and the second device need to interact with data, the two devices can automatically establish a Bluetooth connection by themselves and interact with data through the Bluetooth connection. The entire process does not require user participation, that is, the user does not need to perform device connection operations, thereby simplifying the process of data interaction between devices.

[0083] This application also provides a data interaction method, referring to Figure 3 , Figure 3 This is a flow chart of the second embodiment of the data interaction method of the present application.

[0084] The embodiment of the present application provides an embodiment of the data interaction method. It should be noted that although the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order different from that here. The data interaction method can be applied to a second device, the second device is an AR device or a smart wearable device, the second device includes at least a second UWB (Ultra Wide Band) module, and the second UWB module includes at least a third antenna. It can be understood that the second device is a UWB device.

[0085] For ease of description, the following description of each step of the data interaction method is omitted. The data interaction method includes the following steps:

[0086] Step A10: sending a pulse signal to the first device based on the third antenna, so that the first device receives the pulse signal and determines, based on the pulse signal, whether the relative position relationship between the first device and the second device meets a preset trigger condition;

[0087] Step A20, after the first device determines that the relative position relationship meets the preset trigger condition, establishing a Bluetooth connection with the first device;

[0088] Exemplarily, the first device is a smart wearable device, the second device is an AR device, and the data interaction with the first device based on the Bluetooth connection includes:

[0089] Step f, receiving user data sent by the smart wearable device based on the Bluetooth connection;

[0090] Step g: displaying the user data so that the user can obtain the user data collected by the smart wearable device through the AR device.

[0091] Step A30: interacting with the first device based on the Bluetooth connection.

[0092] In this embodiment, the execution subject is the second device, and the specific implementation method is basically the same as the specific method in which the execution subject is the first device, and will not be repeated here.
