Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Fig. 1 is a flowchart of a display method according to an embodiment of the present invention. As shown in fig. 1, the method comprises the steps of:
and S11, acquiring the identity authentication information of the user.
Here, the user refers to a user of a display device (i.e., a display terminal), i.e., a viewer of the display content.
And S12, according to the acquired identity authentication information, performing identity authentication on the user to determine whether the user passes the identity authentication.
S13, if the user passes the authentication, the tracking display mode is activated, so that the user can display the information in the tracking display mode.
In the embodiment of the invention, before the display in the tracking display mode, in order to ensure the display safety, namely, effectively ensure that the display content is only displayed for the authorized safe user, namely, the effective guarantee authentication only enables the safe user to look up the display content in all directions and in multiple angles, before the display in the tracking display mode, firstly the identity authentication is carried out on the user, only the user passes the identity authentication, the display in the tracking display mode is carried out, otherwise, the display in the tracking display mode is not carried out.
Specifically, in step S11, after the display start operation is detected, the identity authentication information of the user may be acquired, so as to authenticate the user.
The display start operation may refer to "any behavior capable of indicating to-be-displayed to the user", such as a behavior of starting up the display terminal, starting up the display system program, clicking a start button, inputting a start password, and the like, or may refer to a certain operation behavior that triggers display start, such as a behavior of "a display interface of a login tracking display mode" of the user, where "the login display interface" indicates that display has started but a tracking display function has not been started. In general, the "display start operation" may be any operation behavior of the user before the display is performed in the tracking display mode, and the present invention is not limited thereto, and may be set arbitrarily by a person skilled in the art. It is to be understood that the display start operation can also be expressed as a display start instruction for instructing display to the user.
The tracking display mode in the embodiment of the invention refers to tracking the watching position of a user, namely a display content watching person in real time in the display process of the tracking display mode, displaying according to the watching position of the user, so that the display content watched by the user is matched with the watching position of the user, and adaptively adjusting the display content watched by the user when the watching position of the user changes.
For example, adaptive adjustment of one situation may match the display content with different viewing angles of the user, and is suitable for translation by the user when the user moves up and down, left and right, or parallel up and down, left and right, i.e., when the viewing position of the user moves up and down, left and right, the display content viewed by the user also translates accordingly, and when the user rotates, the display content viewed by the user also rotates accordingly.
For another example, for naked eye 3D display, the adaptive adjustment may be such that the display content matches the viewing angle of the user, and after the viewing position of the user changes, the user can still view a correct stereoscopic display effect, thereby avoiding the problem of poor experience of the user, such as vertigo, caused by reverse view, ghost images, distortion, and the like. As described in the foregoing background, for a naked eye 3D display device, that is, an intelligent terminal having a naked eye 3D display function, a display generally includes a display screen and a light splitting device disposed on the display screen, and contents displayed on the display screen enter left and right eyes of a user respectively under the distribution of the light splitting device. Wherein the light splitting device can be a grating, a lens, etc. In this way, if the display content viewed by the user is adaptively adjusted according to the viewing position of the user, the content displayed on the display screen can be changed, or the arrangement mode of the display content on the display screen is adjusted, for example, the position of the pixel point is changed, that is, the original pixel point is moved to a new position, and the like, and the display parameters of the display content, such as the pixel value, the color parameter, such as the gray scale, the saturation, the hue, and the like, can be adjusted, thereby achieving the purpose of adjusting the display content. In addition, since the light splitting of the light splitting device determines what contents enter the left and right eyes of the viewer, if the naked-eye 3D display device employs an adjustable dynamic light splitting device, such as a dynamic slit grating, the display contents viewed by the user can be adjusted by adjusting the light splitting manner of the light splitting device, for example, adjusting the slit width of the light shielding and transmitting of the light splitting device, the tilt angle of the light splitting device, and the like. Of course, the various adjustment methods described above may be used in combination.
It should be understood that the above examples further illustrate the tracking display mode, but the present invention is not limited thereto, and any display mode that tracks the viewing position of the user and performs display adjustment according to the tracking display mode can be considered as the tracking display mode of the present invention, and falls within the protection scope of the present invention.
It is emphasized that in embodiments of the present invention, the viewing position of the user may comprise at least one of a screen translation position and a rotation position.
Specifically, in the tracking display mode, there may be a plurality of ways for tracking the viewing position, for example, the tracking display mode may be a face tracking mode, that is, the viewing position of the user is identified by the position information of the face, and the face position information is tracked during the tracking display. For example, the tracking display mode may be a human eye tracking mode, in which the viewing position of the user is identified by the position information of human eyes, and the position information of human eyes is tracked during tracking display. The eye tracking mode also comprises an eyeball tracking mode, the eyeball is used for marking the watching position of the user, and the tracking and displaying accuracy is greatly improved relatively. The tracking display mode may also be a head pose tracking display mode, i.e., identifying the user's viewing position using the user's head pose. While tracking the display, head pose information is tracked. It is understood that the face tracking, the eye tracking and the head pose tracking can be implemented by using the prior art, and will not be described in detail.
In the embodiment of the present invention, optionally, two identity authentication methods may be adopted to perform identity authentication on a user.
One is an active user authentication method, which requires the user to actively provide identification information for performing identification authentication, and then performs identification authentication using the identification information actively provided by the user, so as to identify whether the user is a secure user, a legitimate user, or an authorized user. Such active authentication methods may include, for example, a fingerprint authentication method, a password authentication method, a voice password authentication method, a physical action authentication method, and the like.
One way is a passive user authentication way, which is different from an active user authentication way, and this way does not require any information provided by the user actively, but the display terminal identifies and authenticates the user, and the terminal will automatically detect and extract some characteristics of the user, such as physical characteristics, and use these characteristics as authentication information for identification and authentication, so as to identify whether the user is a safe user, a legal user or an authorized user. Such passive authentication methods may include, for example, an iris recognition authentication method, a face recognition authentication method, and the like. It will of course be appreciated that in this passive mode, user cooperation is also required if necessary, for example, the user needs to stand at a reasonable location and the display terminal can accurately detect and extract the user's features.
In the case of performing the authentication of the user, whether the authentication is active authentication or passive authentication, it is necessary to first acquire authentication information of the user, for example, fingerprint information, password information, body movement information, voice password information, and the like input by the user, or acquire an eye image of the user using an image acquisition device such as a camera to extract iris feature information of the user from the eye image, or acquire a face image of the user using an image acquisition device such as a camera to extract face feature information of the user from the face image. And then, the identity authentication is carried out on the user by utilizing the acquired identity authentication information.
Alternatively, the authentication information of the secure user, the legitimate user, or the authorized user, that is, the legitimate identity information, may be stored in advance. After the identity authentication information is acquired, the acquired identity authentication information is compared with the pre-stored legal identity information, if the identity authentication information is matched with the legal identity information, for example, the identity authentication information and the legal identity information are the same, the user can be determined to pass the identity authentication, otherwise, the user can be determined to be an illegal user who cannot pass the identity authentication.
For example, the fingerprint information input by the user can be compared with the prestored legal fingerprint information, and the fingerprint information and the prestored legal fingerprint information are identical and pass the authentication; the password information input by the user can be compared with the prestored legal password information, and the password information and the prestored legal password information are identical and pass the authentication; whether the body motion for authentication input by the user is matched with the prestored legal body motion can be identified, and the matching is passed through authentication; whether the voice password input by the user is the same as a pre-stored legal voice password or not can be identified, and the authentication is passed if the voice password is the same as the pre-stored legal voice password; whether the voice of the user is matched with the pre-stored voice information can be identified, for example, the frequency is consistent, the tone is similar, and the matching is authenticated; the iris characteristic information of the user can be compared with the pre-stored legal iris characteristic information, and the authentication is passed if the iris characteristic information is the same as the pre-stored legal iris characteristic information; the face feature information of the user can be compared with the prestored legal face feature information, and the identity is passed through authentication, and the like.
Of course, the identity authentication information of the user is the same as the legal identity information in a matching manner, but the invention is not limited thereto. The legal user can share and agree with a certain special rule with the display terminal, namely, the legal identity information can be the preset special rule, and when the obtained identity authentication information meets the special rule preset by the legal user and the display terminal, namely, the identity authentication information is matched with the legal identity information, the user can be determined to pass the identity authentication.
In a preferred embodiment of the present invention, it is recommended to use iris recognition authentication for identity authentication. Iris recognition technology is based on the iris in the eye for identification. The human eye structure is composed of parts such as the sclera, iris, pupil lens, retina, etc. The iris is an annular segment between the black pupil and the white sclera containing many details characteristic of interlaced spots, filaments, coronaries, stripes, crypts, etc. And the iris will remain unchanged throughout life span after it is formed during the fetal development stage. These features determine the uniqueness of the iris features and also the uniqueness of the identification. Therefore, the iris feature of the eye can be used as an identification target for each person. The iris identification technology is utilized for identity authentication, so that the identification accuracy can be ensured, and the display safety is further improved.
Iris recognition and the aforementioned face recognition are mature in the prior art, and reference may be made to the scheme in the prior art for how to extract iris features and face features and further use the iris features and the face features for identity recognition, which will not be described herein again.
If the user passes the identity authentication, the tracking display mode is started to display in the tracking display mode, for example, naked-eye 3D display is carried out, and display contents are adaptively presented according to the watching position of the user, so that the user can know the display contents in all directions and at multiple angles. On the contrary, if the user can not pass the identity authentication, the tracking display mode can not be started, so that the safety of the display content can be effectively ensured, an illegal user can not deeply know the display content, and the display content with confidentiality can be better protected.
The display method provided by the embodiment of the invention firstly carries out identity authentication on a user, namely a viewer of the display content before the display is carried out in the tracking display mode, the tracking display mode is started when the user passes the identity authentication, and the tracking display mode is not started if the user fails the identity authentication, so that only a legal user who can pass the identity authentication can view the display content from different viewing positions in all directions and at multiple angles, an illegal user cannot view the display content, and the display safety of the display content related to the secret is effectively improved.
When the display is performed in the tracking display mode at step S13, the display terminal will track the viewing position of the user in real time. In order to further improve the security, optionally, in an embodiment of the present invention, after step S13, if the tracking of the viewing position of the user is lost, for example, the user cannot be suddenly searched, when the user is detected by searching again, that is, the viewing position of the user is tracked again, the user is authenticated again, and the tracking display mode is started again when the user passes the authentication again, so as to avoid the tracking display mode being still started even if the user is replaced by an illegal user, and further improve the security.
Specifically, in order to further improve the experience and avoid multiple times of meaningless re-authentication, the tracking lost time is accumulated after the tracking of the watching position of the user is lost, when the watching position of the user is tracked again, whether the tracking lost time is greater than a first preset threshold value or not is judged, if the tracking lost time is greater than the first preset threshold value, the user is subjected to the authentication again, the tracking display mode is started when the user passes the authentication again, if the tracking lost time is not greater than the first preset threshold value, the authentication does not need to be carried out again, and the display is directly carried out in the tracking display mode. Alternatively, the first preset threshold may be set to 1-5 seconds.
Further, optionally, in another embodiment of the present invention, after step S12, if the tracking of the viewing position of the user is lost, the tracking display mode may be directly exited after the tracking is lost, or the tracking display mode may be exited when the tracking loss time reaches a certain threshold, and if the user wants to continue to view, the user needs to perform the authentication again, and after the user passes the authentication, the tracking display mode is restarted. Optionally, the second preset threshold may be set to 1-5 seconds
The tracking display mode is exited in a mode that the tracking display mode can be maintained on a display interface and display content when tracking is lost is maintained on a screen, and in a mode that the tracking display mode is exited directly from the display interface and enters another interactive interface which does not display the original display content. After exiting the tracking display mode, the display information can provide prompt information to prompt the user to perform identity authentication again, and the tracking display mode is started again when the user passes the identity authentication again. For example, a small prompt window may be popped up, and a prompt message and a confirmation button may be displayed on the small window, where the prompt message may be "please perform authentication again", and after the user clicks the confirmation button, the user's authentication information is obtained again to perform authentication on the user.
