[0038] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein.

However, those skilled in the art will recognize that embodiments may be practiced without one or more of these specific details. In other instances, well-known apparatuses, structures, and techniques associated with this application may not have been shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.

[0040] Throughout this specification, references to "an embodiment" or "an embodiment" indicate that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Therefore, the appearance of "in an embodiment" or "an embodiment" in various places throughout the specification does not necessarily refer to the same embodiment. Furthermore, a particular feature, structure, or characteristic may be combined in any manner in one or more embodiments.

[0041] In the following description, in order to clearly demonstrate the structure and working method of the present invention, a number of directional terms will be used. However, terms such as "front", "back", "left", "right", "outside", "inside", "outward", "inward", "up", and "down" should be understood as convenient terms and not as limiting terms.

[0042] like Figure 1 As shown, an embodiment of the present invention provides an information interaction display terminal 100, including: a plurality of NFC sensing interaction modules 110, which are arranged in a two-dimensional manner and cover the display area to be interacted with; each of the plurality of NFC sensing interaction modules 110 includes an NFC radio frequency identification unit 111 and a radio frequency antenna unit 112. The NFC radio frequency identification unit 111 is used to receive electromagnetic field signals sent by a mobile terminal 200 within a preset distance range, and to generate an anchor link based on the electromagnetic field signals and pre-stored information in the current NFC radio frequency identification unit 111 that receives the electromagnetic field signals; the mobile terminal 200 carries an NFC excitation module, the electromagnetic field signals carry first identification information of the mobile terminal 200, and the electromagnetic field signals are used to trigger a touch on the display terminal 100; the pre-stored information includes second identification information corresponding to the NFC radio frequency identification unit 111, location information, and preset URL link information; the radio frequency antenna unit 112 is used to send the anchor link to the mobile terminal 200, so that the mobile terminal 200 can access the cloud server 300 through the anchor link and receive the service link fed back by the cloud server 300.

[0043] In this embodiment, multiple NFC sensing interaction modules 110 are arranged discretely or in an array on the display area. Each NFC sensing interaction module 110 includes multiple NFC radio frequency identification units 111 and radio frequency antenna units 112 arranged discretely or in an array. The NFC radio frequency identification units 111 and the radio frequency antenna units 112 are in one-to-one correspondence and communication link. Here, the radio frequency antenna units 112 and NFC radio frequency identification units 111 of two adjacent NFC sensing interaction modules 110 do not overlap, ensuring that each display area can correspond to a unique NFC sensing interaction module 110. The NFC sensing interaction module 110 is composed of multiple NFC radio frequency identification units 111 and radio frequency antenna units 112, and can accurately provide corresponding feedback based on the sensed electromagnetic field signals. Here, the NFC radio frequency identification unit can be an NFC tag.

[0044] When a user approaches the display area via mobile terminal 200, mobile terminal 200 sends an electromagnetic field signal in real time via the NFC excitation module. This electromagnetic field signal carries the first identification information of the current mobile terminal 200, and the strength of the electromagnetic field signal decreases linearly with increasing distance. When the distance between mobile terminal 200 and the NFC radio frequency identification unit 111 in any NFC sensing interaction module 110 is less than a preset distance, the NFC radio frequency identification unit 111 is activated and can receive the electromagnetic field signal broadcast in real time by mobile terminal 200. Here, when the distance between mobile terminal 200 and the current NFC radio frequency identification unit 111 is less than the preset distance, the strength of the electromagnetic field signal generated by mobile terminal 200 reaches the strength required to activate the current NFC radio frequency identification unit 111. At this point, the current NFC RFID unit 111 is activated. It should be understood that, since the NFC RFID units 111 are evenly distributed in the display area, when the mobile terminal 200 approaches any NFC RFID unit 111, the mobile terminal 200 is closest to the current NFC RFID unit 111, while it is farther away from other NFC RFID units 111. As the mobile terminal 200 continues to approach the current NFC RFID unit 111, the intensity of the generated electromagnetic field signal will become greater for the current NFC RFID unit 111, while it will become smaller for other NFC RFID units 111. Therefore, during the gradual approach, only the current NFC RFID unit 111 will be activated, while other NFC RFID units 111 will not be activated.

[0045] After the current NFC radio frequency identification unit 111 is activated and receives an electromagnetic field signal, it will feed back the generated anchor link to the corresponding mobile terminal 200 according to the first identification information of the corresponding mobile terminal 200 through the radio frequency antenna unit 112 which is connected to it. The anchor link fed back by the radio frequency antenna unit 112 includes the first identification information of the mobile terminal 200, the second identification information of the current NFC radio frequency identification unit 111, pre-stored information, the location information of the touch triggered on the display terminal 100, and the touch time. Further, the mobile terminal 200 forwards the anchor link to the cloud server 300 and accesses the cloud server 300 through the anchor link, so that after receiving the anchor link, the cloud server 300 can quickly locate the service link required by the mobile terminal 200 based on the URL redirection mechanism, and at the same time feed back the service link to the mobile terminal 200.

[0046] Here, the service link is a structured redirect link generated by the cloud server 300 based on the relevant content obtained from parsing the anchor link. The format of the service link conforms to the system requirements of the mobile terminal 200. The service link includes, but is not limited to: web page links, URL Scheme links of applications and lightweight applications such as applications and mini-programs, file download links or other types of digital content. After receiving the service link, the mobile terminal 200 will recognize the service link and, through the system, schedule the corresponding browser or other applications and lightweight application functions of the mobile terminal 200 to complete the provision of the service.

[0047] Here, the display terminal 100 includes, but is not limited to, smart TVs, digital billboards, display screens, computer monitors, in-vehicle central control screens, shop window advertising screens, and information screens for public places; the mobile terminal 200 carries an NFC activation module, and preferably, the mobile terminal 200 is also loaded with several commonly used applications or mini-programs; preferably, the mobile terminal 200 includes, but is not limited to, smartphones, laptops, PADs, smartwatches, smart glasses, all-in-one display screens, smart TVs, smart speakers, and smart robots;

[0048] Display terminal 100 and mobile terminal 200 are based on near-field communication (NFC) and combined with a unified resource location (URL) redirection mechanism. Based on the touch triggered by the mobile terminal 200 and display terminal 100, service links can be quickly located and distributed, which greatly enriches the interaction methods between the display terminal and the mobile terminal in various scenarios. It can bring users a more intelligent, convenient and intuitive interactive experience, thereby promoting the development of visual interaction technology. For display terminal 100, no additional hardware control equipment is required, thereby reducing the production cost of display terminal 100.

[0049] In an optional embodiment of the present invention, the NFC radio frequency identification unit 111 is used to generate an anchor link based on an electromagnetic field signal and pre-stored information in the current NFC radio frequency identification unit 111 that receives the electromagnetic field signal. This includes: the NFC radio frequency identification unit 111 generating touch response information based on the electromagnetic field signal; the touch response information including first identification information of the mobile terminal 200, location information of the touch trigger on the display terminal 100, and touch time; and the NFC radio frequency identification unit 111 generating an anchor link based on the touch response information and the corresponding pre-stored information. The anchor link includes the first identification information of the mobile terminal 200, second identification information of the current NFC radio frequency identification unit 111, pre-stored information, location information of the touch trigger on the display terminal 100, and touch time.

[0050] In this embodiment, since both the mobile terminal 200 and the display terminal 100 are equipped with corresponding NFC modules or units, the trigger condition for the mobile terminal 200 to touch the display terminal 100 is that the mobile terminal 200 approaches the display terminal 100 to a certain distance, or the mobile terminal 200 directly touches the display terminal 100. Therefore, the contact between the mobile terminal 200 and the display terminal 100 can be a physical contact or a virtual contact that is achieved when a certain sensing distance is reached. With the corresponding NFC module or unit, when the user needs to interact, there is no need to unlock the display terminal 100; the user only needs to bring the NFC activation module of the mobile terminal 200 close to the content displayed on the display terminal 100 that needs to be interacted with. The content displayed on the display terminal 100 is information pre-stored in the NFC radio frequency identification unit 111 in chronological order.

[0051] When the NFC radio frequency identification unit 111 receives the electromagnetic field signal, it generates touch response information, which includes the first identification information of the mobile terminal 200, the location information of the touch trigger on the display terminal 100, and the touch time. Furthermore, based on the touch response information and the pre-stored information stored inside the device, it generates an anchor link for the cloud server 300 to parse and feed back to the mobile terminal 200.

[0052] Here, the location information triggered by the touch on the display terminal 100 is the location information of the current NFC radio frequency identification unit 111 that received the electromagnetic field signal, and the touch time is the timestamp corresponding to when the current NFC radio frequency identification unit 111 received the electromagnetic field signal. By carrying the current NFC radio frequency identification unit 111 location information, touch time and pre-stored information in the anchor link, the corresponding service link can be accurately located in the future, so as to ensure that the service link can be quickly and accurately distributed to the corresponding mobile terminal 200.

[0053] In an optional embodiment of the present invention, the NFC radio frequency identification unit 111 includes a plurality of sectors for storing pre-stored information.

[0054] Furthermore, multiple sectors are also used to encrypt pre-stored information according to a preset encryption algorithm to obtain encrypted pre-stored information.

[0055] In this embodiment, each sector uses a preset encryption algorithm and an independent encryption key to encrypt its stored pre-stored information, ensuring that even if a sector is illegally accessed, the complete information cannot be obtained. After each NFC RFID unit 111 completes the writing of pre-stored information, the corresponding sector will automatically enable the encryption protection mechanism to prevent the pre-stored information in the NFC RFID unit 111 from being erased or tampered with, thereby ensuring the security and integrity of the information; the preset encryption algorithm can be an existing encryption algorithm, such as a symmetric key-based encryption algorithm (e.g., AES) or a public key-based encryption algorithm (e.g., RSA).

[0056] In an optional embodiment of the present invention, the plurality of sectors may include an identity information sector, a location information sector, and a URL link sector. The identity information sector stores second identification information corresponding to the NFC radio frequency identification unit 111; the location information sector stores location information corresponding to the NFC radio frequency identification unit 111; and the URL link sector stores preset URL link information corresponding to the NFC radio frequency identification unit 111.

[0057] In this embodiment, the preset URL link information stored in the URL link sector can be set according to the chronological order of the content to be displayed by the display terminal 100, and each preset URL link information corresponds to a display timestamp, and each preset URL link information corresponds one-to-one with the display content information of the display terminal 100 at the corresponding position; here, the display content information at the corresponding position of the display terminal 100 is mainly used to characterize the application content or data currently opened by the display terminal 100, which may include: any one of the following: images, audio, video, and files; such as the advertising video currently playing by the video advertising player, and the playback progress, etc.

[0058] Specifically, the content information displayed at the corresponding location on the display terminal 100 includes, but is not limited to, any one or more combinations of version information, functional module identifier, content identifier, content timestamp, time node, progress status, and link address; or, any one or more combinations of data format, data size, data name, creation time, and modification time.

[0059] When the mobile terminal 200 activates the current NFC radio frequency identification unit 111, the current NFC radio frequency identification unit 111 will match the touch time of the triggered touch with the display timestamp of the preset URL link information in the URL link sector. When the difference between the timestamp corresponding to the touch time and the display timestamp is less than a set time value, the current NFC radio frequency identification unit 111 will extract the preset URL link information corresponding to the current display timestamp, the second identification information of the current NFC radio frequency identification unit 111, and the location information to generate an anchor link, thereby facilitating the subsequent accurate and rapid distribution of service links determined based on the redirection mechanism by the cloud server.

[0060] like Figure 2 As shown, embodiments of the present invention also provide an information interaction system, including the display terminal 100 as described in the above embodiments, and further including:

[0061] The mobile terminal 200 and the cloud server 300 are used to receive the anchor link sent by the mobile terminal 200 and provide a service link in return.

[0062] In this embodiment, the cloud server 300 is used to receive the anchor link sent by the mobile terminal 200, parse the anchor link to obtain the relevant parameter information of the corresponding display terminal 100 and the NFC radio frequency identification unit 111 of the display terminal, process the relevant parameter information and redirect it to the required service link, and feed it back to the corresponding mobile terminal 200 according to the first identification information of the mobile terminal 200.

[0063] like Figure 2 As shown, in an optional embodiment of the present invention, the cloud server 300 includes an identity verification module 301, a parameter parsing module 302, and a URL resource location module 304. The identity verification module 301 receives an anchor link sent by the mobile terminal 200; the parameter parsing module 302 parses the anchor link to obtain the display content information of the display terminal 100 at the touch location when the mobile terminal 200 touches the display terminal 100, as well as the preset URL link information of the display terminal 100, and generates a structured redirection link based on the display content information and the preset URL link information; the URL resource location module 304 determines the service link required by the mobile terminal 200 based on the structured redirection link and sends the service link to the mobile terminal 200.

[0064] In this embodiment, sending an anchor link from the mobile terminal 200 to the cloud server 300 is equivalent to accessing the cloud server 300 through the anchor link;

[0065] Here, the identity verification module 301 is the portal of the cloud server 300. When a user touches any NFC radio frequency identification unit 111 of the NFC interaction sensing module 110 using a mobile terminal 200 with an NFC excitation module and obtains the second identification information of the NFC radio frequency identification unit 111 and the anchor link generated at the corresponding touch position (the NFC radio frequency identification unit 111 at the touch position) on the display terminal, and sends the anchor link to the cloud server 300, the anchor link first enters the identity verification module 301. The identity verification module 301 will obtain the first identification information of the mobile terminal 200 used by the user and perform identification.

[0066] Preferably, in an optional embodiment of the present invention, when a user accesses the identity verification module 301 for the first time through the mobile terminal 200, they need to register an account and log in using personal information such as a mobile phone number or email address. After logging in, an identity information file will be generated and stored in the mobile terminal 200, and the user can skip the login process for the next 30 days. The identity verification module 301 can directly obtain the user's login information from the identity information file stored in the mobile terminal 200. If the user has not logged in for more than 30 days, they need to log in again using their registration information.

[0067] After obtaining the anchor link, the parameter parsing module 302 parses the anchor link and obtains the relevant information of the display terminal 100, the second identification information of the NFC radio frequency identification unit 111 of the current display terminal, the display content information corresponding to the current NFC radio frequency identification unit 111, and the preset URL link information corresponding to the display content contained in the anchor link; further, the parameter parsing module 302 determines the structured redirection link of the service required by the user based on the display content information, the preset URL link information, the first identification information of the user and the corresponding mobile terminal 200, and passes the structured redirection link to the URL resource location module 304;

[0068] The URL resource location module 304 constructs a service link pointing to the user's required service based on the structured redirect link. After the service link is fed back to the mobile terminal 200, it guides the user to the service corresponding to the content displayed in the corresponding display area of ​​the display terminal 100 at the moment the user touches it. The service link includes, but is not limited to, web pages, applications, mini-programs, file downloads, or other types of digital content. Here, the URL resource location module 304 can be a URL unified resource locator to realize the rapid distribution and modification of service links, thereby improving the user's interactive experience. At the same time, the service feedback is carried out by distributing service links through the cloud server 300, which can avoid installing related hardware control modules or microcontrollers in the display terminal, thereby reducing the hardware cost of the display terminal.

[0069] The following example illustrates the process by which the URL resource locator module 304 constructs a service link pointing to the user's desired service based on the structured redirect link:

[0070] Currently, display terminal 100 is playing a video advertisement. When a user touches display terminal 100 with mobile terminal 200, and the second identification information of NFC radio frequency identification unit 111 at the touch location is 25, and the touch location has coordinates x=20, y=3, the identification number of display terminal 100 becomes 1. Then, the radio frequency antenna unit 112 at the corresponding touch location sends the following anchor link to mobile terminal 200: https: / / service-offer.com / login? screen_id = 1 & id = 25 & x = 20 & y = 3; The user uses mobile terminal 200 and accesses cloud server 300 via HTTP protocol and anchor link. After logging in through identity verification module 301, parameter parsing module 302 performs data query based on the anchor link parameters and the current display timestamp. Finding that the content displayed on the terminal 100 is a product advertisement, it generates structured data: {“service_type”:advertisement,“url_type”:schema,“service_context”:“123456”}. “service_type”:advertisement indicates the current service type is product advertisement; “url_type”:schema indicates the service link is schema; “service_context”:“123456” indicates the product number of the service content is 123456. URL resource location module 304 constructs and distributes the following service link URL_SCHEMA based on the above structured data: taobao: / / item.taobao.com / item.html? The URL id=123456 can be directly resolved by mobile devices and will open the shopping app, redirecting users to the order page for product number 123456.

[0071] Preferably, in an optional embodiment of the present invention, before the URL resource location module 304 constructs the service link, the URL resource location module 304 will also perform a security check on the received structured redirect link to ensure that the service link constructed based on the structured redirect link will not cause the user to access a malicious website or download harmful content, thereby further improving the user's interactive experience.

[0072] In an optional embodiment of the present invention, the information interaction system further includes a data storage module 303. This data storage module 303 stores the first identification information of the mobile terminal 200 in the anchor link, the second identification information of the current NFC radio frequency identification unit 111, the touch location triggered by the touch on the display terminal 100, and the touch time.

[0073] In this embodiment, the data storage module 303 persistently stores the first identification information of the user's mobile terminal 200, the relevant information of the display terminal 100 (the second identification information of the touched NFC radio frequency identification unit 111, the location information of the touch triggered by the touch on the display terminal 100, the touch time and the pre-stored information of the corresponding NFC radio frequency identification unit 111, and the display content information corresponding to the touch trigger location on the display terminal 100), the cloud service information corresponding to the cloud server, and the correspondence between them in the cloud server 300. It can also receive external instructions and change the stored relevant information in real time as needed. At the same time, the data storage module 303 is also used to store the user information corresponding to the mobile terminal 200 to provide the parameter parsing module 302 and the URL resource positioning module 304 with the data information required when generating relevant links. Here, the cloud service information includes, but is not limited to: product information, program jump links, mini-program jump links, web page jump links, and data, and the data includes: any one of images, audio, video, and files.

[0074] Preferably, the user information stored in the data storage module 303 includes, but is not limited to: contact information such as mobile phone and email address, and encrypted privacy information such as login account and password.

[0075] In an optional embodiment of the present invention, the parameter parsing module 302 is used to parse the anchor link to obtain the display content information of the display terminal 100 at the touch position when the mobile terminal 200 triggers the touch of the display terminal 100 and the preset URL link information of the display terminal 100. This includes: the parameter parsing module 302 decrypting the pre-stored information in the anchor link to obtain the decrypted pre-stored information, and determining the display content information according to the decrypted pre-stored information.

[0076] In this embodiment, when the parameter parsing module 302 performs decryption processing, it can use the same algorithm as each sector in the NFC radio frequency identification unit 111, and decrypt the encrypted pre-stored information contained in the anchor link (which is the reverse process of pre-stored information encryption). Since the preset URL link information in the pre-stored information corresponds one-to-one with the content information displayed at the corresponding position of the display terminal 100, after the parameter parsing module 302 decrypts and obtains the corresponding preset URL link information, it can search for the display content information corresponding to the display timestamp of the preset URL link information from the data storage module 303, so as to generate structured redirect links in the future.

[0077] like Figure 3 As shown, embodiments of the present invention also provide an information interaction method applied to a display terminal, comprising:

[0078] Step 11: Receive electromagnetic field signals sent by the mobile terminal 200 within a preset distance range;

[0079] Step 12: Generate an anchor link based on the electromagnetic field signal and the pre-stored information in the current NFC radio frequency identification unit 111 that receives the electromagnetic field signal; the mobile terminal 200 carries an NFC excitation module, the electromagnetic field signal carries the first identification information of the mobile terminal 200, the electromagnetic field signal is used to trigger a touch on the display terminal 100, and the pre-stored information includes the second identification information, location information and preset URL link information corresponding to the NFC radio frequency identification unit 111;

[0080] Step 13: Send the anchor link to the mobile terminal 200 so that the mobile terminal 200 can access the cloud server 300 through the anchor link and receive the service link fed back by the cloud server 300.

[0081] In this embodiment, the display terminal 100 receives the electromagnetic field signal from the mobile terminal 200 via NFC (Near Field Communication) and feeds back an anchor link containing encrypted preset URL link information from the mobile terminal 200. This allows the cloud server 300 to quickly locate the service link required by the user based on the URL redirection mechanism when the mobile terminal 200 accesses the cloud server 300 via the anchor link, and promptly feeds back to the user. This enables the display terminal 100 to recognize the location information, time information, and preset URL link information corresponding to the content touched by the mobile terminal 200 on the display area. As a result, different interaction results are achieved based on the different content touched on the display terminal 100, enriching the interaction methods between the display terminal 100 and the mobile terminal 200 in various scenarios and improving the popularity of NFC technology.

[0082] The following is a specific implementation example illustrating the process by which the NFC RFID unit 111 generates an anchor link based on the electromagnetic field signal and the pre-stored information in the current NFC RFID unit 111 that receives the electromagnetic field signal:

[0083] Currently, a video advertisement is playing on the display terminal 100. At this moment, the mobile terminal 200 touches the position on the display terminal 100 where the content displayed is a backpack. This position is located at (20, 3) in a coordinate system with the upper left corner of the display terminal 100 as the origin, the x-axis to the right as positive, and the y-axis downward as positive. At this time, the NFC radio frequency identification unit 111 in the NFC sensing interaction module 110 at the corresponding position senses the touch and is activated, sending an anchor link in the form of: https: / / service-offer.com / login?screen_id=1&id=25&x=20&y=3 to the mobile terminal 200. This anchor link only displays a part of the information identifier, and the anchor link conforms to the HTTP (Hypertext Transfer Protocol) requirements, and is responded to by the browser of the mobile terminal 200.

[0084] The anchor link is explained in detail as follows: https: / / service-offer.com represents the access domain name, login is the entry link of the identity verification module 301, and the part following the question mark ? is the parameter list. The parameters are assigned using equal signs and separated by the & symbol. Screen_id=1 indicates that the identification number of the display terminal 100 touched by the mobile terminal 200 is 1. id=25 indicates that the identification information of the NFC radio frequency identification unit 111 in the NFC sensing interaction module 110 triggered by the mobile terminal 200 is 25. x=20&y=3 indicates that the coordinates of the NFC radio frequency identification unit 111 in the aforementioned NFC sensing interaction module 110 are (20, 3) with the upper left corner of the display terminal 100 as the origin, the positive x-axis to the right, and the positive y-axis downward (i.e., the touch position information).

[0085] It should be noted that before interaction, the mobile terminal 200 that the user needs to interact with should have the necessary media program. However, this media program can also be embedded in the operating system of the mobile terminal 200, thus making it invisible to the user. This is different from the existing card reader mode and peer-to-peer mode, which are mainly limited by software. Here, the media program application can be any application already installed on the mobile terminal 200. That is, any program on the mobile terminal 200 can interact with the display terminal 100. For example, by using an online shopping program or a map navigation program, by touching the display terminal 100, users can use the cloud server to access web pages or online shopping and map navigation on the display terminal 100, without having to download the application required to implement the function separately.

[0086] The following two examples illustrate specific application scenarios of the display terminal 100 provided in the above embodiments of the present invention:

[0087] Example 1: When display terminal 100 is made into a computer monitor:

[0088] Users can tap on a file on the desktop with their phone to access the file directly from their phone.

[0089] Users can tap a webpage in their computer's browser with their phone to open the website directly on their phone.

[0090] Users can tap different software icons in a computer browser with their mobile phones to access different content. For example, tapping a media player on a mobile phone can play a movie on a computer, and tapping a music app on a mobile phone can play the corresponding music.

[0091] Users can also tap on blank areas of the computer to establish a connection, allowing them to slide files, messages, and texts from their phones directly to the computer desktop.

[0092] Example 2: When display terminal 100 is made into a public display window:

[0093] The display terminal 100 can display different advertising windows in public places, such as playing video advertisements. Different positions in the same screen correspond to different products, such as clothing, jewelry, and handbags on models, or tables, chairs, home appliances, and decorative paintings in home scenes. Users can touch the corresponding products in the display terminal 100 with their mobile phones. The mobile phone will determine the position of each product in the current screen and automatically pop up the payment interface of the corresponding product's cloud mini-program to complete the purchase.
