Fig. 1 is a schematic view of an application scenario of an information display method shown in the present disclosure according to an exemplary embodiment. The application scene comprises a user and a smart phone. When a user needs to send a short message or browse an internet webpage, the user can operate the display screen of the smart phone to display the input panel through the thumb and input short message information or keyword information through the input panel.
When the smart phone detects that the input panel is displayed in the display screen, the smart phone indicates that the user may need to input information at the moment, and in order to sense the input information exactly needed by the user, the smart phone starts a face detection function and transmits a face detection signal.
In an embodiment, when the smart phone transmits the face detection signal, the smart phone turns on or changes the turned-on millimeter wave transmitting antenna and the turned-on radio frequency module, so that the smart phone sends the face detection signal with a certain power (such as the maximum power) by taking the default range of the front of the smart phone as the detection direction, and detects whether the corresponding echo signal is received.
When the smart phone receives information input by a user through an input panel and echo signals detected after the face detection signals are transmitted, the matching degree between each piece of alternative information corresponding to the information input by the user and the face echo signals is calculated, each piece of alternative information is sorted according to the matching degree, and each piece of ordered alternative information is displayed.
Therefore, the order of each piece of candidate information displayed in the embodiment is related to the matching degree, so that the candidate information most matched with the face echo signal is easily ranked at the top, and the method is beneficial to quick selection of a user, thereby improving the input efficiency of the user.
Fig. 2 is a flowchart illustrating an information display method according to an exemplary embodiment of the present disclosure, where the information display method may be applied to a terminal and may be implemented by installing corresponding information display software on the terminal, and as shown in fig. 2, the information display method may include the following steps 210 to 240:
in step 210, a face detection signal is transmitted while the input panel is displayed.
The terminal in the present disclosure may be any intelligent terminal having an internet access function, and may be specifically a mobile phone, a tablet computer, a Personal Digital Assistant (PDA), or the like. The terminal can access the router through the wireless local area network and access the server on the public network through the router.
In this embodiment, when the input panel is displayed on the display screen of the terminal, it indicates that the user may need to input information at this time, and in order to sense the input information exactly needed by the user, the smart phone may start the face detection function, that is, turn on or change the turned-on millimeter wave transmitting antenna and radio frequency module, so that the smart phone sends a face detection signal with a certain power (such as maximum power) using the default range of the front of the smart phone as a detection direction, and detects whether a corresponding echo signal is received.
In an embodiment, the emitting the face detection signal while displaying the input panel may include:
when the input panel is displayed, a face detection function is started;
setting the self front setting range as the detection direction and transmitting the human face detection signal with the set power.
In an embodiment, if it is detected that the input panel is no longer displayed on the display screen, the face detection signal is turned off.
In this embodiment, if it is detected that the input panel is no longer displayed on the display screen, indicating that the user is no longer inputting information, the face detection signal may be stopped from being transmitted, so that energy consumption of the terminal may be reduced.
In step 220, first information and a face echo signal are received. The first information is information input by a user through an input panel, and the face echo signal is an echo signal detected after the face detection signal is transmitted.
In this embodiment, the terminal receives the user input information and also receives the face echo signal detected for the user. By analyzing the echo signals of the face, the positions of the cheek and the lip of the user, namely the facial actions of the user, can be obtained, and the information which the user exactly needs to input is obtained from the facial actions of the user.
In an embodiment, if the first information is received but the face echo signal is not received, the transmitting direction and/or the transmitting power of the face detection signal are adjusted until the face echo signal is received or the preset time period is exhausted, and then the adjustment is stopped.
In this embodiment, if only the first information is received but the face echo signal is not received, which indicates that the transmission direction of the face detection signal is wrong or the transmission power is too small, the transmission direction, the transmission power, and the like of the face detection signal may be adjusted until the face echo signal is received or the preset time period is exhausted, and then the adjustment is stopped.
In addition, if a face echo signal is received, but the effect of the face echo signal is not good, the face features of the user cannot be extracted from the face echo signal, which indicates that the transmission power of the face detection signal at this time is too small, and the transmission power needs to be further increased, so that the terminal provides a signal adjustment function, and is convenient for obtaining the most accurate positions of the cheek and the lips of the user.
In step 230, the matching degree between each candidate information corresponding to the first information and the face echo signal is calculated, and each candidate information is sorted according to the matching degree. Wherein the alternative information is information that prompts the user to make a selection.
In this embodiment, if the input panel displayed on the display screen of the terminal is a nine-grid input panel, the nine-grid input panel has 9 number buttons, each number button represents 3-4 letters, and when a user inputs information, the user can click one or more number buttons of the nine-grid input panel to achieve the purpose of inputting information.
Such as: if the user needs to input the 'like' word, three digital buttons of 9, 2 and 6 can be pressed; after the user input information received by the terminal is "926", obtaining the pinyin combination corresponding to "926" may be: the method comprises the steps of wan, yan, yao, zan, zao and the like, calculating the matching degree of a face echo signal and alternative pinyins of wan, yan, yao, zan, zao and the like, if the fact that the face echo signal is most matched with the pronunciation action of zan is obtained from the calculated matching degrees, then arranging the alternative pinyins of zan at the top, and displaying the alternative pinyins sequenced through the matching degree, so that a user can find the words of 'liking' quickly, and the input efficiency of the user is improved.
In an embodiment, when calculating a matching degree between each candidate information corresponding to the first information and the face echo signal, and sorting each candidate information according to the matching degree, the method may include:
acquiring each alternative information corresponding to the first information;
extracting first face characteristic information from the face echo signal;
acquiring second face feature information corresponding to each alternative information in a set information base;
calculating the matching degree between the first face feature information and second face feature information corresponding to each alternative information;
and sequencing the alternative information according to the calculated matching degrees, wherein the sequencing is performed in a descending order according to the matching degrees.
See the embodiment shown in fig. 3 for details.
In step 240, the candidate information sorted according to the matching degree is displayed.
It can be seen from the above embodiments that, by transmitting the face detection signal, receiving the face echo signal, and using the face echo signal to participate in the sorting of the respective alternative information corresponding to the first information, and sorting according to the matching degree between the face echo signal and the respective alternative information, and displaying the respective alternative information sorted according to the matching degree, the alternative information most matched with the face echo signal is easily arranged at the top, which is beneficial for the user to select quickly, so that the input efficiency of the user can be improved.
Fig. 3 is a flowchart illustrating another information display method according to an exemplary embodiment of the present disclosure, where the information display method may be applied to a terminal and may be implemented by installing corresponding information display software on the terminal, and as shown in fig. 3, the information display method may include the following steps 300 to 390:

In step 310, the self front setting range is set as the detection direction, and the face detection signal is transmitted with the set power.
In step 320, first information and a face echo signal are received. The first information is information input by a user through an input panel, and the face echo signal is an echo signal detected after the face detection signal is transmitted.
In this embodiment, the first information and the face echo signal are generally received at the same time, and the face echo signal is a sequence of each auxiliary information corresponding to the auxiliary first information. Even if the face echo signal is received later than the first information, the information sequencing is not delayed. However, if the face echo signal is not received after the first information is received, at this time, the input panel further needs to display the alternative information prompting the user, and at this time, the first sequencing information obtained in step 340 may be directly displayed, which is described in detail in the embodiment of fig. 4.
In step 330, each candidate information corresponding to the first information is obtained.
In this embodiment, after receiving the information input by the user, the terminal automatically obtains the standby information for prompting the user to select.
Such as: after the user inputs "xih" on the pinyin panel, the system obtains the following spare information: west ring, likes, refines, etc.
In step 340, first face feature information is extracted from the face echo signal.
In this embodiment, the first facial feature information mainly includes information of the cheeks and lips of the user.
In one embodiment, the first facial feature information includes, but is not limited to, at least one of the following facial feature indicators:
maximum lip opening, minimum lip opening, maximum lip reflection intensity, minimum lip reflection intensity, rate of lip deformation, duration of lip deformation, chin position information, and cheek reflection intensity information.
In step 350, second face feature information corresponding to each candidate information is obtained in the setting information base.
In this embodiment, the setting information base is an information base in which face features corresponding to common information are stored. Such as: the setting information base stores cheek feature information and lip feature information corresponding to the common information.
In step 360, a matching degree between the first face feature information and the second face feature information corresponding to each candidate information is calculated.
In this embodiment, if the first face feature information has only one face feature index, the matching degree between the face feature index and the same face feature index corresponding to each piece of alternative information may be directly calculated.
In an embodiment, if the first facial feature information includes at least two facial feature indexes, a set weight value corresponding to each facial feature index is obtained;
calculating the matching degree between each face characteristic index in the first face characteristic information and the face characteristic index corresponding to each alternative information;
and carrying out weighted summation on the matching degrees corresponding to the same candidate information obtained by calculation according to the set weight values to obtain the matching degree between the first face feature information and the second face feature information corresponding to the candidate information.
Such as: the first face feature information includes a cheek index 1 and a lip index 1, the alternative information includes alternative information 1 and alternative information 2, the weight of the cheek index 1 is weight 1, the lip index 1 is weight 2, the matching degree of the index corresponding to the cheek index 1 and the alternative information 1 is matching degree 1, the matching degree of the index corresponding to the lip index 1 and the alternative information 1 is matching degree 2, the matching degree of the index corresponding to the cheek index 1 and the alternative information 2 is matching degree 3, the matching degree of the index corresponding to the lip index 1 and the alternative information 2 is matching degree 4, then the matching degree 5 of the first face feature information and the alternative information 1 is shown in formula (1), and the matching degree 6 of the first face feature information and the alternative information 2 is shown in formula (2):
matching degree 5 ═ weight 1 × matching degree 1+ weight 2 × matching degree 2 … … … … … … … … formula (1)
Matching degree 6 ═ weight 1 × matching degree 3+ weight 2 × matching degree 4 … … … … … … … … equation (2)
In step 370, the candidate information is sorted according to the calculated matching degrees, and the sorting is performed in descending order according to the size of the matching degree.
In this embodiment, the candidate information corresponding to the maximum matching degree is the information closest to the exact input by the user, and all the information needs to be ranked first.
In step 380, the candidate information items are displayed in descending order according to the matching degree.
It can be seen from the above embodiments that, after receiving the first information, the first information may be sorted by using the matching degree between the face echo signal and each of the candidate information, the sorting may be performed in a descending order according to the size of the matching degree, and each of the candidate information after the descending order is displayed for the user to select, so that the sorted candidate information is closer to the exact input information of the user, the user can select quickly, the input satisfaction of the user is improved, and the input efficiency of the user is also improved.

in step 400, a face detection signal is transmitted while the input panel is displayed.
In step 410, it is determined whether a first message and a face echo signal are received, where the first message is a message input by a user through an input panel, and the face echo signal is an echo signal detected after a face detection signal is transmitted. If the first information and the face echo signal are received, go to step 420; if the first information is received but the face echo signal is not received, step 440 is executed.
In step 420, the matching degree between the face echo signal and each candidate information corresponding to the first information is calculated, and each candidate information is sorted according to the matching degree. Wherein the alternative information is information that prompts the user to make a selection.
In step 430, the information alternatives sorted according to the matching degree are displayed, and the process ends.
In step 440, obtaining each candidate information corresponding to the first information;
in step 450, the respective candidate information is sorted according to a set rule, wherein the set rule includes that the candidate information with high use frequency is arranged in front of the candidate information with low use frequency is arranged in back of the candidate information with high use frequency.
In step 460, the information alternatives sorted according to the set rule are displayed, and the process ends.
It can be seen from the above embodiments that, if the first information is received, but the face echo signal is not received, the alternative information sorted according to the set rule can be displayed, so that even if the face detection signal is out of order, normal display of the alternative information can be guaranteed, and the face detection signal is set as the sort of the auxiliary alternative information, thereby improving the practicability of information display.
