Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
When the interactive video is played to an interactive node, a user needs to promote the plot development or select different plot development directions through interactive operation; taking the example that different branch scenarios are set behind the interactive node, when the interactive video is played to the interactive node, the user needs to be prompted to complete the interactive operation through the prompt information displayed on the terminal screen, so that the selection of the branch scenarios is realized in a man-machine interaction manner.
When an interactive video is played to an interactive node at present, a user is prompted to select a branch scenario mainly through options displayed on a terminal screen, the branch scenario corresponding to the option clicked by the user is used as the branch scenario selected by the user, the user is prompted to simply select the options only through displaying the options in the interactive video playing process, the user participation degree is low, and the immersive experience of the video cannot be brought.
Based on this, the embodiment of the invention considers the face action of the user as the interactive operation of the user, so that when the interactive video is played to an interactive node, the real-time face image of the user is collected on the basis of prompting the user to execute the target face action by displaying the interactive prompt information at least indicating the target face action, and whether the real-time face action corresponding to the real-time face image is matched with the target face action is detected, so as to realize the detection of whether the interactive operation of the user is correct, further determine the subsequent playing content of the interactive video based on the face action of the user, and improve the participation of the user in the playing process of the interactive video.
As an optional implementation, fig. 1 shows an optional flow of a video playing method provided in an embodiment of the present invention, where the method may be executed by a terminal, and the terminal may be an electronic device such as a smart phone, a tablet computer, a PC (personal computer), or a smart television that plays a video; referring to fig. 1, the process may include:
and S100, if the video to be played has the interactive label, acquiring an interactive script corresponding to the video.
The interactive label is label information for distinguishing the interactive video from the non-interactive video; the video with the interactive label is an interactive video, and a user is supported to participate in interaction in the video playing process. Optionally, an interactive tag attribute may be added to the video in the embodiment of the present invention, and a value setting of the interactive tag attribute may indicate whether the video has an interactive tag, for example, if the value of the interactive tag attribute of the video is 1, the video has the interactive tag, and if the value of the interactive tag attribute of the video is 0, the video does not have the interactive tag.
Aiming at a video to be played by a terminal, if the video is provided with an interactive label, the embodiment of the invention can determine that the video is an interactive video and support a user to participate in interaction in the playing process of the video; in order to realize user interaction, the embodiment of the invention can acquire the interaction script corresponding to the video, and the interaction script can set interaction nodes, interaction modes, interaction requirements and the like of the user participating in the interaction.
And S110, when the video is played to the interactive node of the video recorded by the interactive script, displaying the interactive prompt information corresponding to the interactive node.
The interactive script can record interactive nodes of the video, the video can be provided with one or more interactive nodes, and when the video is played to any interactive node, a user can carry out interactive operation, so that the plot development of the video is promoted or different plot development directions are selected.
In the process of playing the video at the terminal, when the video is played to the interactive node, the embodiment of the invention can display the interactive prompt information on the screen of the terminal, so that a user can carry out interactive operation based on the prompt of the interactive prompt information. Because the embodiment of the invention takes the facial action of the user as the interactive operation of the user, in order to ensure that the user has the reference standard when executing the facial action, the interactive prompt information can at least indicate the target facial action to be executed by the user; the target facial action may be a facial expression action (such as smiling, frown, etc.), or may be a facial rotation action, and any facial action that can be captured by the facial image may be supported by the embodiments of the present invention, and the embodiments of the present invention are not limited thereto.
Optionally, the embodiment of the present invention does not limit the display form of the interactive prompt information, including but not limited to: the display form of the small window, the display form of the rolling bullet screen, the display form of the message bullet window, the display form of the superposition on the video interface and the like; in addition, the display position of the interactive prompt information is not limited in the embodiment of the present invention, for example, the interactive prompt information may be displayed at any position of the video interface, and of course, the embodiment of the present invention may preferentially select a position where the video interface is not blocked or a position where the video interface is less blocked, and display the interactive prompt information; in another optional implementation, the embodiment of the present invention may also display the interaction prompt information in a region of the terminal screen other than the video interface, for example, in a case that the video is not played in a full screen, the interaction prompt information may be displayed in the non-video interface of the terminal screen.
It should be noted that, the embodiment of the present invention does not limit the execution sequence of the interactive script corresponding to the video playing and the video obtaining, and the two may be executed in parallel or have a sequential execution sequence; for example, an interactive script of a video may be obtained first, and then the video may be played; the video can also be played first, and the corresponding interactive script can be obtained as soon as possible in the process of playing the video, for example, the corresponding interactive script can be obtained immediately after the video is played.
And step S120, acquiring a real-time face image of the user, and detecting whether the real-time face action of the user is matched with the target face action required by the interaction prompt information based on the real-time face image.
The embodiment of the invention can acquire the real-time face image of the user by activating the camera of the terminal, thereby realizing the acquisition of the real-time face image of the user; optionally, if the terminal detection camera does not acquire the face image of the user, a prompt that the face image is not detected may be displayed on the terminal interface, so that the user places the face within the viewing range of the terminal camera. Optionally, in the embodiment of the present invention, the camera of the terminal may be activated when the video is played to the interactive node, and the situation that the camera is always activated is not excluded.
Optionally, for example, when the terminal plays the video through the video application, the video application should have an authority to call the terminal camera, so that the camera of the terminal can be activated to obtain the real-time facial image of the user acquired by the camera.
When the real-time facial image of the user is acquired through the camera of the terminal, the embodiment of the invention can identify the real-time facial action corresponding to the real-time facial image based on the acquired real-time facial image, and detect whether the real-time facial action of the user is matched with the target facial action required by the interactive prompt information so as to judge whether the user executes the target facial action according to the requirement of the interactive prompt information.
For example, based on different forms of target facial movements, the form of the real-time facial movement recognized from the real-time facial image may also be different, for example, if the target facial movement is a left turn of the face, the real-time facial movement recognized from the real-time facial image should be a face turning angle (the face turning angle may have direction information and angle specific numerical information), and if the target facial movement is a frown, the real-time facial movement recognized from the real-time facial image should be a movement of the eyebrow region; based on target facial actions with different requirements, the embodiment of the present invention is adaptable to adjusting the form of the identified real-time facial action, and may be specifically determined according to the actual interaction setting, which is not limited by the embodiment of the present invention.
And step S130, according to the matching result, playing the branch video content of the video corresponding to the matching result.
It can be understood that the matching result is divided into two cases: the real-time facial action matches the target facial action, and the real-time facial action does not match the target facial action. In optional implementation, the embodiment of the present invention may preset the interaction time for the user to perform the interaction operation, so as to detect whether the real-time facial action matches the target facial action within the preset interaction time, and obtain a matching result; in a more specific optional implementation, if the real-time facial motion matches the target facial motion at least once within the interaction time (the number of times may be set according to the actual situation, for example, one or more times), the embodiment of the present invention may immediately obtain the matching result of the real-time facial motion matching the target facial motion, that is, the user has executed the target facial motion as required by the interaction prompt information; if the real-time facial action is not matched with the target facial action all the time in the interaction time, when the interaction time is over, the embodiment of the invention can obtain a matching result that the real-time facial action is not matched with the target facial action, namely, the user does not execute the target facial action according to the requirement of the interaction prompt information in the interaction time.
Based on the obtained matching result, the embodiment of the invention can play the branch video content of the video corresponding to the matching result. Optionally, the interactive node of the video may correspond to a plurality of branch video contents in different plot trends, and different results of the user interactive operation may realize selection of different branch video contents, so as to promote the plot to develop in different directions, for example, in the embodiment of the present invention, a first branch video content corresponding to the target facial action and a second branch video content corresponding to the non-target facial action may be set in the embodiment of the present invention, and the first branch video content and the second branch video content are branch video contents in different plot trends; therefore, when the matching result is that the real-time facial action is matched with the target facial action, the embodiment of the invention can play the first branch video content corresponding to the target facial action, and when the matching result is that the real-time facial action is not matched with the target facial action, the embodiment of the invention can play the second branch video content corresponding to the non-target facial action.
In another optional implementation, a branch video content of a single scenario trend may be set behind an interactive node of a video, and a user may push the video to play the branch video content after performing a required interactive operation, for example, in an embodiment of the present invention, the video may smoothly push the next branch video content only when a real-time facial action of the user matches a target facial action, so that the embodiment of the present invention may play the next branch video content of the video when a matching result is that the real-time facial action matches the target facial action; and when the matching result is that the real-time facial action is not matched with the target facial action, the subsequent content of the video is not played, at the moment, the embodiment of the invention can circularly prompt the user to carry out the target facial action, and the next branch video content of the video is not played until the matching result that the real-time facial action of the user is matched with the target facial action is obtained.
According to the video playing method provided by the embodiment of the invention, the face action of the user is taken as the interactive operation of the user, and for the video with the interactive label, in the video playing process, when the video is played to the interactive node of the video recorded by the interactive script, the embodiment of the invention can display the interactive prompt information corresponding to the interactive node, so that at least the target face action executed by the user is prompted through the interactive prompt information; furthermore, the embodiment of the invention can acquire the real-time facial image of the user through the camera of the terminal, identify the real-time facial action corresponding to the real-time facial image by utilizing an image identification technology, and detect whether the real-time facial action is matched with the target facial action, so as to realize the purpose of detecting whether the user executes the target facial action according to the requirement of the interaction prompt information; after the matching result is obtained, the embodiment of the invention can play the branch video content of the video corresponding to the matching result according to the matching result, thereby realizing the purpose of promoting the video to play the branch video content or selecting the branch video content with different plot trends based on the facial action of the user. Therefore, the video playing method provided by the embodiment of the invention can be provided for an interactive video producer as a technical solution for supporting the realization of the interactive video, and when the video is played to an interactive node, a user can determine the subsequent playing content of the video through the facial action, namely the interactive operation of the user is embodied by the facial action of the user, the participation degree of the user is higher, and the participation degree of the user in the interactive video playing process can be improved.
In an optional implementation of step S110, when the video is played to the interactive node, the embodiment of the present invention may display the interactive prompt information by displaying the interactive prompt image and/or the interactive prompt text. The interactive prompt image may be considered as an image-form interactive prompt information for displaying the target facial action in an image manner, and the interactive prompt image may be a dynamic image, and may visually prompt the user about the target facial action to be executed by displaying the dynamic image of the target facial action, and certainly, the interactive prompt image may also be a static image, which is not limited in the embodiment of the present invention. The interactive prompt text may be considered as text-form interactive prompt information for describing the target facial action in a text manner, and optionally, the interactive prompt text may be further combined with the video content of the interactive node, for example, the interactive prompt text may describe an influence on a video scenario after the user performs the target facial action.
For example, taking the target facial action as a face turning to the left and the video content of the interactive node as a video character to hide scars on the face as an example, as shown in fig. 2, the interactive prompt image may be set as a dynamic image of the face turning to the left, and the interactive prompt text may be set as "turn to the left to expose scars".
Optionally, in the embodiment of the present invention, an interactive prompt image or an interactive prompt text may be selectively displayed to display the interactive prompt information, or the interactive prompt image and the interactive prompt text may be simultaneously displayed to display the interactive prompt information.
In an optional implementation, in order to perform real-time feedback on the facial action performed by the user from the display aspect, the embodiment of the invention may further display the interactive feedback information based on the real-time facial action of the user, so that the user can clearly understand the real-time facial action performed by the user through the displayed interactive feedback information. Optionally, the interactive feedback information may at least include a face model image, and the facial motion of the face model image is adjusted in real time along with the identified real-time facial motion; for example, as shown in fig. 3, a video interface may display a face model image of a human face shape, where the face model may be a 3D model or a 2D model, and based on a real-time face motion recognized by an embodiment of the present invention, the face motion of the face model image may be adjusted in real time, so that the face motion of the face model image is consistent with the real-time face motion, and if the face of a user rotates left, the face model image also rotates left, and if the face of the user rotates right, the face model image also rotates right.
By reflecting the real-time facial action of the user as the facial action of the face model image, the embodiment of the invention can feed back the facial action of the user in real time from the display aspect, so that the user can correct the facial action in time through the prompt of the face model image in the process of executing the facial action, the invalid interaction is reduced, and the success rate of the facial action of the user is improved.
Optionally, the interactive feedback information may further include interactive feedback text, where the interactive feedback text may indicate a deviation between the real-time facial motion and the target facial motion, so as to remind the user how to correct the facial motion in a text manner; for example, taking the target facial motion as a leftward turning face and the turning angle value reaching a certain value as an example, when the real-time facial motion of the user is detected as the leftward turning face, the interactive feedback text may prompt to continue turning the face leftward, and when the real-time facial motion of the user is detected as the rightward turning face, the interactive feedback text may prompt that the face turning direction is wrong, so as to prompt the user to correct the facial motion in a text manner.
In optional implementation, in the stage of displaying the interactive prompt information, the embodiment of the invention prompts the user of the target facial action to be executed through the interactive prompt image and the interactive prompt text; in the stage of displaying the interactive feedback information, the embodiment of the invention can feed back the real-time facial action of the user in real time through the facial model image and the interactive feedback characters; the jumping of the two stages can be controlled by whether a camera of the terminal collects a face image of the user or not; optionally, fig. 4 shows another flow of the video playing method provided by the embodiment of the present invention, and as shown in fig. 4, the flow may include:
and S200, if the video to be played has the interactive label, acquiring an interactive script corresponding to the video.
And S210, displaying an interactive prompt image and interactive prompt characters when the video is played to the interactive node of the video recorded by the interactive script.

firstly, displaying interactive feedback information according to the real-time facial action, and thus carrying out real-time feedback on the facial action of a user from a display level; the interactive feedback information at least comprises a face model image and interactive feedback characters, the face action of the face model image is adjusted in real time along with the real-time face action, and the interactive feedback characters indicate the deviation between the real-time face action and the target face action;

And step S240, according to the matching result, playing the branch video content of the video corresponding to the matching result.
Optionally, the embodiment of the present invention may also set whether to execute the step of displaying the interactive prompt information, for example, the interactive prompt display time may be preset, for example, the interactive prompt display time is set by a video producer, a video publisher, or a user; when the video is played to the interactive node, the embodiment of the invention can detect whether the preset interactive prompt display time is more than 0; if the value is greater than 0, the interactive prompt information is set to be not skipped, so that the step of displaying the interactive prompt information can be entered in the embodiment of the invention, for example, an interactive prompt image and/or interactive prompt text are displayed; if not greater than 0, it is said that the interaction prompt information is set to be skippable, the embodiment of the present invention may skip the step of displaying the interaction prompt information, and execute the process downwards, for example, after acquiring the real-time facial image of the user, execute step S230 shown in fig. 4.
In an alternative implementation, for convenience of describing the process of detecting whether the real-time facial motion matches the target facial motion according to the embodiment of the present invention, an alternative implementation of step S120 shown in fig. 1 is described below by taking a face rotation motion as an example, and optionally, fig. 5 shows an alternative flow for detecting whether the real-time facial motion matches the target facial motion, and as shown in fig. 5, the flow may include:
and S300, identifying a real-time face rotation angle corresponding to the real-time face image.
In an embodiment of the invention, the real-time facial motion of the user is represented by a real-time facial rotation angle of the user.
Step S310, detecting whether the real-time face rotation angle is within a preset target face rotation angle range.
In the embodiment of the present invention, the target face action is represented by a preset target face rotation angle range.
In an alternative implementation of the flow shown in fig. 5, the face rotation angle may refer to a specific angle value without indicating the face rotation direction.
In an alternative implementation of the flow shown in fig. 5, the face rotation angle indicates the face rotation direction in addition to the specific angle value; for example, the face rotation angle may be an angle with positive and negative values, the positive and negative values of the face rotation angle represent the face rotation direction, and the specific angle value (i.e. the absolute value of the angle) represents the specific rotation angle value in the face rotation direction; illustratively, if the position of the initially acquired user face image is taken as the origin, the left rotation is taken as the positive direction, and the right rotation is taken as the negative direction, the face rotation angle is 30 °, which means that the user face rotates 30 ° to the left from the initially acquired state, and the face rotation angle is-30 °, which means that the user face rotates 30 ° to the right from the initially acquired state; of course, the positive and negative directions of the face rotation angle may be a left rotation direction and a right rotation direction, and the positive and negative directions of the face rotation angle may be set according to actual situations, which is not limited in the embodiments of the present invention.
Under the condition that the face rotation angle has a positive value and a negative value, the embodiment of the invention can identify the real-time face rotation direction corresponding to the real-time face image and the rotated angle value of the real-time face rotation direction as an optional implementation mode for identifying the real-time face rotation angle of the user; for example, the real-time face rotation direction is determined by the positive and negative values of the real-time face rotation angle, and the rotated angle value of the real-time face rotation direction is determined by the specific angle value of the real-time face rotation angle.
Optionally, under the condition that the face rotation angle has a positive value and a negative value, the embodiment of the invention can preset the target face rotation angle range to define the target face action; for example, if the left rotation is a positive direction, the right rotation is a negative direction, and the target face movement is a left rotation greater than 30 °, the target face rotation angle range is greater than 30 °, or if the target face movement is a right rotation greater than 30 °, the target face rotation angle range is less than-30 °, for example, -40 ° is less than-30 °.
In an alternative implementation, the method for defining the target face rotation angle range according to the embodiment of the present invention includes: a target face rotating direction and an angle lower limit value corresponding to the target face rotating direction; for example, if the target face moves to the left and rotates more than 30 °, the target face rotates to the left and the lower limit value of the angle is 30; once the real-time face rotation direction of the user is consistent with the target face rotation direction and the rotated angle value of the real-time face rotation direction is greater than the angle lower limit value, the embodiment of the invention can determine that the real-time face rotation angle of the user is within the target face rotation angle range, so that the real-time face action of the user is matched with the target face action; based on this, the embodiment of the present invention may detect whether the real-time face rotation direction is consistent with the target face rotation direction, and detect whether a rotated angle value of the real-time face rotation direction is greater than the angle lower limit value when the real-time face rotation direction is consistent with the target face rotation direction, so as to detect whether the real-time face rotation angle is within the target face rotation angle range.
In a further optional implementation, in the process of performing the face rotation by the user, there may be a case where an extreme error occurs in the real-time face rotation direction of the user, for example, the real-time face rotation direction of the user is not consistent with the target face rotation direction, and the rotated angle value of the user in the real-time face rotation direction is greater than the angle lower limit value, at this time, the user rotates an angle greater than the angle lower limit value in the direction opposite to the target face rotation direction, which is seriously deviated from the target face action required by the interactive prompt information, so as to provide a striking error prompt for the user, an alarm icon may be displayed in the embodiment of the present invention; for example, assuming that the target face is rotated to the left by more than 30 °, if it is detected that the real-time face rotation direction of the user is rotated to the right and the rotated angle value is more than 30, the embodiment of the present invention may display a warning icon; meanwhile, when the real-time face rotating direction is detected to be consistent with the target face rotating direction and the rotated angle value of the real-time face rotating direction is larger than the angle lower limit value, a correct icon can be displayed so as to provide an interactive correct prompt for a user; in addition to the above-described cases, the embodiment of the present invention may not perform display of other icons;
for example, assuming that the face is rotated leftward as a positive direction, the face is rotated rightward as a negative direction, and the target face action is rotated leftward more than 30 °, fig. 6 shows an example of icon display, which can be referred to; as shown in fig. 6, the real-time face rotation angle > 30 °, the correct icon is displayed, the real-time face rotation angle is less than-30 °, the warning icon is displayed (i.e. at this time, the real-time face rotation direction of the user is rightward rotation, the angle is negative, and the value of the rightward rotation angle is greater than 30), when the real-time face rotation angle > 30 °, the icon is not displayed, the opposite sign in fig. 6 may represent the correct icon, and the exclamation mark may represent the warning icon.
The above-described warning icon and correct icon may be used in conjunction with interactive feedback information (facial model images and/or interactive feedback text) to provide feedback information in a variety of ways during the course of the user's facial movements.
Optionally, after the matching result is obtained, the embodiment of the present invention may further display the interaction result prompt information according to the matching result, where the step may be performed before playing the branch video content of the video corresponding to the matching result according to the matching result; it is understood that the interactive result prompt message may include: and when the real-time facial action is matched with the target facial action, prompting information of an interaction success result, and when the matching result is not matched with the target facial action, prompting information of an interaction failure result.
Based on the preset setting, the embodiment of the present invention may also skip the step of displaying the prompt information of the interaction result, for example, a video producer, a video publisher, or a user may set the display time of the prompt information of the interaction result, if the display time is greater than 0, the step of displaying the prompt information of the interaction result according to the matching result is performed, otherwise, the step of displaying the prompt information of the interaction result according to the matching result is skipped.
Optionally, after determining the matching result, the embodiment of the present invention may immediately play the branch video content of the video corresponding to the matching result according to the matching result, for example, immediately play the first branch video content of the video when determining that the matching result is that the real-time facial action matches the target facial action, and immediately play the second branch video content of the video when determining that the matching result is that the real-time facial action does not match the target facial action; of course, after the matching result is determined, the embodiment of the present invention may also set that a step of playing the branch video content of the video corresponding to the matching result according to the matching result is performed after the video content corresponding to the interactive node is played;
in a more specific implementation, a video content skip switch may be preset, and the turning on or off of the video content skip switch may be set by a video producer, a video publisher, or a user, so that after a matching result is determined, if the video content skip switch is detected to be turned on, the embodiment of the present invention may proceed to a step of playing the branch video content of the video corresponding to the matching result according to the matching result, thereby immediately playing the corresponding branch video content; when it is detected that the video content skip switch is not turned on, the step of playing the branch video content of the video corresponding to the matching result according to the matching result is only started when the playing of the video content corresponding to the interactive node is finished.
