[0077] In some embodiments, the system runtime layer provides support for the upper layer, namely the framework layer. When the framework layer is used, the Android operating system will run the C / C++ library contained in the system runtime layer to implement the functions to be implemented by the framework layer.

[0078] In some embodiments, the kernel layer is a layer between hardware and software. Figure 4 As shown, the kernel layer includes at least one of the following drivers: audio driver, display driver, Bluetooth driver, camera driver, WIFI driver, USB driver, HDMI driver, sensor driver (such as fingerprint sensor, temperature sensor, pressure sensor, etc.), and power driver, etc.

[0079] Intelligent voice is an important part of artificial intelligence technology. With the development of technology, users are more and more accustomed to using voice to control display devices. However, due to the diversity of user pronunciation, it is difficult for users to accurately and skillfully control display devices through voice, which brings a bad user experience.

[0080] In order to solve the above technical problems, an embodiment of the present application provides a method for browser page text prompt messages, which displays text prompt messages for the current browser page, thereby guiding the user to master voice operations and then accurately control the display device through voice operations.

[0081] The method, such as Figure 5 As shown, it includes: S100, receiving an instruction to display a text prompt message. S200, determining a text prompt message according to a browser page. S300, displaying the text prompt message on the browser page.

[0082] In some embodiments, the instruction to display the text prompt message can be sent directly by voice. For example, the user can say "display text prompt message", and the instruction to display the text prompt message is generated accordingly. In some embodiments, the instruction to display the text prompt message can be generated by pressing a preset button. For example, the user can press the language key on the control device. The instruction to display the text prompt message can also be generated by continuously pressing the preset button. For example, press the voice key twice. Of course, the instruction to display the text prompt message can also be generated by other key combinations. For example, press the up key first and then the down key.

[0083] In some embodiments, the buttons on the control device can also be reused. When the button is pressed, the command generated by the button can be determined according to other conditions. In some embodiments, a preset key value input of the control device is received to determine whether a text prompt message has been displayed on the browser page; if the text prompt message has been displayed, an instruction to hide the text prompt message is generated; if the text prompt message has not been displayed, an instruction to display the text prompt message is generated. In this way, the use of too many buttons can be avoided and the complexity of use can be reduced.

[0084] In the embodiment of the present application, a text prompt message can be determined according to the content of the current browser page, and text prompt messages can be provided to users in different scenarios. For example, when the browser page is a home page, the text prompt messages are all about the content of the home page. For example, Figure 6 As shown, the browser page displays tool, bookmark and history related command prompts, such as add tag, close tag, show history, show bookmark, select first, return, forward, save to bookmark, home page, refresh page, zoom in and zoom out. When the browser page is a media playback page, prompts for playback related instructions will be displayed, for example, Figure 7 As shown, for example, play now, pause, full screen, exit full screen, restart, fast back half an hour, fast forward 5 minutes and stop playing. When the browser page is a regular search page, the text prompt messages are all about the content of the search page. For example, when multiple results are searched, a text prompt message can be displayed at the corresponding position of each result. The text prompt message can be determined according to the position order of the results on the browser page, for example, click the first one, click the second one, click the third one, etc.

[0085] In an embodiment of the present application, a corresponding text prompt message is determined based on the currently browsed browser page, and the text prompt message is displayed on the browser page. Through the content in the text prompt message, the user is guided to use voice commands to control the current browser page. This can prevent the user from using incorrect or improper voice commands, which affects the user's efficiency in controlling the browser page.

[0086] In some embodiments, the step of determining a text prompt message based on the browser page includes: obtaining a web page element in the browser page; determining a text prompt message based on the web page element. In an embodiment of the present application, the web page element refers to a control that can obtain focus and can implement certain functions by operating the focus. Exemplarily, when the browser page is a media playback page, the web page element may be a pause control, a play control, a progress adjustment control, etc. The embodiment of the present application determines the operations that can be performed on the current browser page based on the web page element, and then determines the content of the text prompt message, so as to achieve the purpose of accurately prompting the user. In some embodiments, text prompt messages corresponding to different web page elements can be pre-stored. Exemplarily, when the web page element is a pause control, the content of the text prompt message can be to pause video playback.

[0087] In order to reduce occupied resources, in some embodiments, the web page element is a web page element within a visible range, and the visible range refers to a range that can be displayed on a display, in other words, refers to an area that a user can see on the display.

[0088] In some embodiments, the method further includes: determining the display position of the text prompt message according to the position of the web page element, and displaying the text prompt message at the display position. In order to minimize the obstruction of the content of the browser page, the embodiment of the present application limits the display position of the text prompt message. In some embodiments, the display position of the text prompt message on the browser page can be determined according to the type of web page element. For example, if the web page element is a text element, the upper left corner coordinate of the web page element can be used as the lower left corner coordinate of the text prompt message. If the web page element is a picture element, the upper left corner coordinate of the web page element can be used as the upper left corner coordinate of the text prompt message.

[0089] In some embodiments, the method further comprises: determining an attribute of the text prompt message according to the website to which the browser page belongs, the attribute representing a display style of the text prompt message; and displaying the text prompt message on the browser page according to the attribute. In the embodiment of the present application, in order to make the screen after the text prompt message and the browser page are superimposed more coordinated, the attribute is used to determine the display style of the text prompt message in the browser page.

[0090] In some embodiments, the attributes include background color, background transparency, border, and / or text attributes, etc. In some embodiments, the attributes of the website and its corresponding text prompt message may be pre-stored. For example, when the name of the website is identified, the attributes of the text prompt message displayed in the browser page corresponding to the website may be determined.

[0091] In some embodiments, the method further includes: identifying the color of the browser page, determining the attributes of the text prompt message according to the color; and displaying the text prompt message on the browser page according to the attributes. In some embodiments, the method for determining the color of the browser page may include: acquiring an image including the current browser page, parsing the image, determining the main body color of the browser page according to the parsing result, and determining the attributes of the text prompt message using the main body color. The main body color refers to the color of the largest number of pixels in the image of the browser page. In some embodiments, multiple colors and corresponding attributes may be pre-stored, and a matching attribute may be selected according to the color.

[0092] In some embodiments, the method further comprises: receiving an instruction to hide the text prompt message, and controlling the browser page not to display the text prompt message. In the embodiment of the present application, after the text prompt message is displayed on the browser page, the text prompt message can also be cancelled, so that multiple options can be provided to the user.

[0093] In some embodiments, the method for displaying the text prompt message on the browser page includes:

[0094] 1. Create a new style element using the following JavaScript code ( element) and set the name (className). The elStyle attribute is used to specify The attributes of the element include the acquired coordinate element, as well as the background color, background transparency, border, text attributes and other attributes.
