[0047] In order to solve the technical problem of how to secretly give prompts to the speaker during the speech in the prior art, the present application provides a prompting method, device, head-mounted device and storage medium, which can control the page turning of the prompting content according to the angle change data through the head-mounted device, so as to secretly give prompts to the speaker through the head-mounted device, help the speaker improve the quality of the speech and improve the user experience.

[0048] The first embodiment of the present application provides a prompting method, which can be applied to Figure 1 The system architecture shown in the figure includes at least a data acquisition module 101 and a data processing module 102, and the data acquisition module 101 and the data processing module 102 establish a communication connection. Specifically, the system architecture can be a head-mounted device, for example, a virtual reality device (such as VR glasses), an augmented reality device (such as AR glasses), or a mixed reality (MixedReality) device (such as an MR head-mounted display), etc., without limitation.

[0049] Next, based on the system architecture, the word prompting method is described in detail. Figure 2 , the prompting method includes:

[0050] Step 201, obtaining the prompt content.

[0051] The content of the prompt can be a document that prompts the target object, specifically, it can be a multi-page document adapted to the display interface of the head-mounted device. The content of the prompt can be transmitted to the head-mounted device in advance, or it can be obtained from the smart terminal or server through Bluetooth (BT) technology, Bluetooth Low Energy (BLE) technology or other communication methods. Taking the head-mounted device as AR glasses as an example, AR glasses have the ability to display text content. The number and length of text lines that can be displayed on the lenses of different models of AR glasses may be different. The document can be adaptively calculated and adjusted according to the display capability of the AR glasses. For example, according to the model of the AR glasses, it is determined how many pages of documents the prompt content includes, how many lines each page of the document is divided into, and the size, font, font color, and number of text per line of text when displayed on the AR glasses are not restricted.

[0052] Step 202: When the target object wears a head mounted device, obtain angle change data of the target object's head within a preset time period.

[0053] In one embodiment, the step of obtaining the angle change data of the target object's head within a preset time length includes: determining that within the preset time length, the target object's head switches from a first posture to a second posture; wherein the first posture is used to indicate that the absolute value of the angle change of the target object's head within the first time length is less than or equal to a first threshold; the second posture is used to indicate that the absolute value of the angle change of the target object's head within the second time length is greater than the first threshold and less than or equal to the second threshold; the first time length is less than or equal to the preset time length, and the second time length is less than or equal to the preset time length; calculating the maximum value of the angle change of the target object's head within the preset time length; and using the maximum value of the angle change as the angle change data.

[0054] In this embodiment, the target object may be a speaker who is giving a speech while wearing a head mounted device. Taking the head mounted device as an example of AR glasses, the AR glasses include a collection unit that can collect angle change data, such as an inertial measurement unit (IMU). The IMU may include sensors such as an accelerometer, a gyroscope, and a magnetometer, and may collect motion data of a user wearing AR glasses in various directions. For example, the angle change data may include horizontal angle change data and vertical angle change data. Both the horizontal angle change data and the vertical angle change data may be determined by the data fusion of the accelerometer and the gyroscope. Of course, the data of the magnetometer may also be combined for calibration, without specific limitation.

[0055] In this embodiment, when the user wears AR glasses to give a speech, the head generally swings left and right or up and down (with different movement amplitudes), which will cause the absolute value of the horizontal angle and the absolute value of the vertical angle of the AR glasses to change. When collecting angle change data, the data can be collected when the user's head switches from the first posture to the second posture. The first posture indicates that the absolute value of the angle change within the first time length is less than or equal to the first threshold. The first threshold can be a relatively small data. The absolute value of the angle change is less than or equal to the first threshold. It can be considered that the user's head movement amplitude is relatively small, which is approximately equal to the head being in a static state. The second posture indicates that the absolute value of the angle change within the second time length is greater than the first threshold and less than or equal to the second threshold. The process of the user's head switching from the first posture to the second posture can be a process of obvious head movement. The preset time length can be a relatively short time period, such as 1s, 500ms or 100ms, etc. AR glasses can continuously detect whether the user suddenly moves from a static state in a certain direction within the preset time length to a certain amplitude that can trigger page turning. Similarly, the first time length and the second time length are to indicate the state of the user within the time length, and can also be a relatively short time period, which is not greater than the preset time length, and there is no specific limitation. It should be noted that the first threshold value and the second threshold value, etc., can have different values ​​at the horizontal angle and the vertical angle, respectively, and the embodiments of the present application do not limit this.

[0056] In this embodiment, when it is determined that the head of the target object switches from the first posture to the second posture within the preset time, the maximum value of the angle change in this process is collected as the angle change data. Of course, during the collection process, the horizontal angle and the vertical angle can be collected separately, for example, the maximum value of the horizontal angle change is collected as the horizontal angle change data, and the maximum value of the vertical angle change is collected as the vertical angle change data. Then, the horizontal angle change data and the vertical angle change data can be used as different page turning control instructions respectively. The user only needs to make slight movements in the corresponding direction to control the prompt content on the glasses of the AR glasses to turn the pages. The AR glasses can be used to provide prompts secretly, helping users improve the quality of their speeches.

[0057] In one embodiment, the step of calculating the maximum value of the angle change of the target object's head within a preset time length includes: obtaining a first angle interval in which the target object's head is located within a first time length; obtaining a second angle interval in which the target object's head is located within a second time length; and determining the maximum value of the angle change of the target object's head within the preset time length based on the first angle interval and the second angle interval.

[0058] In this embodiment, when calculating the maximum value of the angle change of the target object's head within a preset time length, the first angle interval in which the target object's head is located within the first time length can be obtained, and the second angle interval in which the target object's head is located within the second time length can be obtained, and the maximum value of the angle change of the target object's head within the preset time length can be determined based on the first angle interval and the second angle interval. Specifically, the calculation can be performed separately for the horizontal angle and the vertical angle. For example, the first angle interval in which the horizontal angle is located within the first time length and the second angle interval in which the horizontal angle is located within the second time length are obtained, and the maximum value of the horizontal angle change on the horizontal angle is calculated. And, the first angle interval in which the vertical angle is located within the first time length and the second angle interval in the second time length are obtained, and the maximum value of the vertical angle change on the vertical angle is calculated.

[0059] Step 203, controlling the page turning of the prompt content according to the angle change data.

[0060] The method can display the prompt content to the target object through the head-mounted device, and because the target object wears the head-mounted device, the head-mounted device can collect the angle change data of the target object's head, so the head-mounted device can be used to control the page turning of the prompt content according to the angle change data, so as to secretly prompt the speaker through the head-mounted device, help the speaker improve the quality of the speech, and enhance the user experience.

[0061] In one embodiment, the angle change data includes horizontal angle change data and vertical angle change data, and the step of performing page turning control on the prompt content according to the angle change data includes: performing a first page turning control on the prompt content according to the horizontal angle change data, and performing a second page turning control on the prompt content according to the vertical angle change data; wherein the first page turning control includes one of turning down or turning up, and the second page turning control includes the other of turning down or turning up.

[0062] In this embodiment, the angle change data may include horizontal angle change data and vertical angle change data, and the prompt content may be subjected to a first page turning control according to the horizontal angle change data, and the prompt content may be subjected to a second page turning control according to the vertical angle change data. For example, the first page turning control may be a down page turning, and the second page turning control may be an up page turning. Of course, the first page turning control may be an up page turning, and the second page turning control may be a down page turning, without limitation.

[0063] In one embodiment, the step of obtaining the prompt content includes: obtaining a current prompt page from a smart terminal connected to the head-mounted device; wherein the current prompt page is one of a plurality of pages obtained by paging the prompt document according to a preset format by the smart terminal.

[0064] Correspondingly, the step of controlling page turning of the prompt content according to the angle change data includes: sending a page number switching instruction to the smart terminal according to the angle change data to obtain a target page corresponding to the page number switching instruction from the smart terminal; wherein the target page is the previous page or next page of the current prompt page.

[0065] In this embodiment, the smart terminal can be, for example, a user's mobile phone, and the mobile phone and the AR glasses can be linked and exchange data via Bluetooth technology BT or BLE.

[0066] A prompting application (APP) for the AR glasses prompting function can be installed on the mobile phone. The prompting APP can adjust the horizontal angle threshold A and vertical angle threshold B when the user is speaking, and can select the AR glasses to be connected via Bluetooth. Among them, the horizontal angle threshold A means that when the horizontal angle of the AR glasses changes by more than the threshold A, the page turning control execution X (such as turning the next page) is triggered, and the vertical angle threshold B means that when the vertical angle of the AR glasses changes by more than the threshold B, the page turning control instruction Y (such as turning the previous page) is triggered. Through the prompting APP, you can select the document for prompting prepared locally on the user's mobile phone, parse the prompting document after obtaining it, and divide the content of the prompting document into chapters (the number of words in each chapter is adapted to the number of words displayed on the glasses, and the length and word limit can be customized), set the page number for the chapter, and finally store it locally in the prompting APP. The prompting APP sends the encoded current page content and the page number to the AR glasses via Bluetooth. The AR glasses receive and parse the content via Bluetooth and display the prompting content on the glasses. The AR glasses save the current page number. The AR glasses issue a page turning instruction (such as issuing an X instruction to turn to the next page or issuing a Y instruction to go back to the previous page) and send it to the mobile phone prompting APP with the current page number. The mobile phone prompting APP receives the page turning instruction and decides whether to send the next or previous page content to the AR glasses based on the received current page number. The above page turning operation is performed continuously according to the user's speech operation. After the speech, the mobile phone can be disconnected from the AR glasses, and then reconnected when in use, and the prompting document can be imported.

[0067] In one embodiment, the method further includes: deleting the prompting content when it is determined that the prompting task is completed.

[0068] In this embodiment, in order to protect the security of the data and not occupy the storage space of the AR glasses, the prompt content saved in the AR glasses can be deleted when it is determined that the prompt task is completed.

[0069] In one embodiment, the step of controlling page turning of the prompt content according to the angle change data includes: controlling page turning of the prompt content when the angle change data belongs to the first change interval.

[0070] Correspondingly, the method also includes: when the angle change data belongs to the second change interval, display control of the prompt content; wherein the display control includes at least one of pausing the prompt, continuing the prompt, enlarging the font and reducing the font; wherein the second change interval does not overlap with the first change interval.

[0071] In this embodiment, when the absolute value of the horizontal angle change is in the first change interval, the page turning control of the prompt content can be performed. For example, the first change interval can be between A and A+Range (A, A+Range), where A is the minimum value of the horizontal angle threshold, and A+Range is the maximum value of the horizontal angle threshold. If the absolute value of the horizontal angle change is in the first change interval, an X instruction is issued for turning the page down, where the X instruction is the instruction agreed upon between the AR device and the mobile phone application. Similarly, the first change interval of the absolute value of the vertical angle change can be between B and B+Range (B, B+Range), where B is the minimum value of the vertical angle threshold, and B+Range is the maximum value of the vertical angle threshold. If the absolute value of the vertical angle change is in the first change interval, a Y instruction is issued for turning the page up, where the Y instruction is the instruction agreed upon between the AR device and the mobile phone application. It should be understood that the values ​​of Range can be set separately as needed for the horizontal angle and the vertical angle.

[0072] In this embodiment, when the angle change data belongs to the second change interval, the prompting content can be displayed and controlled, such as pausing the prompting, continuing the prompting, enlarging the font and reducing the font, etc. The second change interval does not overlap with the first change interval. Specifically, the angle change amplitude in the second change interval can be a larger amplitude than the angle change amplitude in the first change interval.

[0073] In various embodiments of the present application, the page turning control of the prompting can be performed through the head-mounted device, so that the speaker can be prompted secretly, which is convenient for the speaker to give a speech. The speaker does not need to prepare paper speeches in advance, and no additional terminal is required to control the page turning, which improves the speaker's confidence in giving impromptu speeches.

[0077] The prompt control module 303 is used to control the page turning of the prompt content according to the angle change data.

[0078] The device can display the prompt content to the target object through a head-mounted device, and because the target object wears the head-mounted device, the head-mounted device can collect angle change data of the target object's head, so the head-mounted device can be used to control the page turning of the prompt content according to the angle change data, thereby secretly prompting the speaker through the head-mounted device, helping the speaker to improve the quality of the speech and enhance the user experience.
