     TECHNICAL FIELD 
     The present disclosure relates to the field of display control, and in particular, to a content presentation method, a content presentation mode push method, and an intelligent terminal. 
     BACKGROUND 
     As science and technology develop rapidly, intelligent terminals are more widely used. Besides cell phones, tablet computers, and the like, more types of intelligent terminals begin to emerge, for example, wearable devices such as GOOGLE GLASS and a SAMSUNG GEAR smartwatch. To enable a user to conveniently obtain more information, an intelligent terminal generally has a display function. 
     Currently, an intelligent terminal may present content to a user in different presentation modes, for example, by a screen display or projection display and by a voice broadcast. 
     However, currently an intelligent terminal can present content to a user in a specific presentation mode only selection by the user. When a presentation mode of the intelligent terminal cannot conveniently enable, in a current scenario, the user to acquire required information, for example, when light is relatively strong, which prevents the user from clearly seeing content on a screen, the user needs to modify the presentation mode to select a more suitable content presentation mode in the current scenario, and a requirement of the user for a content presentation mode in the current scenario may be difficult to be met after multiple times of switching. As a result, operations and a time that are required by the user to acquire the information are increased, and efficiency of acquiring the information by the user is reduced.

     DESCRIPTION OF EMBODIMENTS 
     The following clearly describes the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are merely some but not all of the embodiments of the present disclosure. All other embodiments obtained by persons skilled in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure. 
     Referring to  FIG.  1   , an embodiment of a content presentation method in the embodiments of the present disclosure includes: 
       101 : An intelligent terminal acquires context data of a user. 
     When the intelligent terminal is in a powered-on state, the intelligent terminal can acquire the context data of the user. 
       102 : The intelligent terminal identifies a user use scenario according to the context data. 
     After the intelligent terminal acquires the context data, the intelligent terminal identifies the user use scenario according to the context data, where the user use scenario is used to indicate a scene in which the user currently uses an intelligent device. 
       103 : The intelligent terminal determines a first presentation mode, which corresponds to the user use scenario, of a presentation mode. 
     After identifying the user use scenario, the intelligent terminal determines the first presentation mode, which corresponds to the use scenario, of the presentation mode, where the presentation mode indicates a content presentation mode. 
     It may be understood that, the presentation mode may include a mode that can be used to present content, such as screen switching, switching to large screen display, projection display, holographic display, and voice broadcast, which is not limited herein. 
       104 : The intelligent terminal presents content to the user in the first presentation mode. 
     After determining the first presentation mode corresponding to the user use scenario, the intelligent terminal presents the content to the user in the first presentation mode. 
     In this embodiment of the present disclosure, an intelligent terminal acquires context data of a user, identifies a user use scenario according to the context data, determines a first presentation mode corresponding to the user use scenario, and presents content to the user in the first presentation mode. In this way, the intelligent terminal can intelligently present the content to the user in different presentation modes according to different scenarios, thereby meeting a requirement of the user for a content presentation mode in different environments, and the intelligent terminal can identify a current scenario according to the acquired context data, and then directly present the content to the user in the corresponding first presentation mode, thereby reducing operations and a time that are required by the user to acquire information, increasing a rate of acquiring the information, and improving user experience. 
     In an actual application, an intelligent terminal may present content to a user in a second presentation mode in advance, and after acquiring context data, determine whether the context data changes compared with context data acquired in a previous acquiring cycle, and then perform a subsequent operation. Referring to  FIG.  2   , another embodiment of a content presentation method in the embodiments of the present disclosure includes: 
       201 : An intelligent terminal presents content to a user in a second presentation mode. 
     When content needs to be presented or the user is presenting the content in the second presentation mode, the intelligent terminal may present the content to the user in the second presentation mode. 
       202 : The intelligent terminal acquires context data of the user. 
     When the intelligent terminal presents the content to the user in the second presentation mode, the intelligent terminal may acquire the context data of the user. 
     The context data may also be referred to as context information, and refers to information such as a history record of a location, an action, and a behavior of the user. The context data may be obtained from various pieces of source information, for example, a light sensor may be invoked to detect light intensity, a camera may be invoked to detect a surrounding medium available for projection, a microphone may be invoked to detect intensity of use environment noise, a motion sensor may be invoked to detect moving state data of the user, a global positioning system GPS or Wireless Fidelity WiFi may be invoked to identify location information of a current user, or a battery management unit may be invoked to detect a current battery level, which is not limited herein. 
     In summary, the context data reflects some attribute information related to the user. 
     The intelligent terminal may be set to acquire the context data once at a specific interval, a preset condition may be set to trigger acquisition of the context data, or the context data may be continuously acquired, which is not limited herein. 
     It may be understood that, in step  201  and step  202 , the intelligent terminal first presents the content to the user in the second presentation mode, and then acquires the context data. In an actual application, the intelligent terminal may first not present the content in a presentation mode, and may directly acquire the context data when detecting that content needs to be presented, and then perform a subsequent operation according to the context data. 
       203 : The intelligent terminal determines whether the context data changes compared with context data acquired in a previous acquiring cycle. 
     After acquiring the context data, the intelligent terminal determines whether the context data changes compared with the data acquired in the previous acquiring cycle, and if the context data changes, step  204  is triggered, or if the context data does not change, step  202  is triggered. 
     It may be understood that, if the intelligent terminal has acquired context data before currently acquiring context data, and in this case, the intelligent terminal determines the second presentation mode according to the context data acquired last time or context data that is the same as the context data acquired last time, the intelligent terminal may determine whether the currently acquired context data changes compared with the context data acquired last time, if the intelligent terminal has not acquired context data before currently acquiring context data, for example, the second presentation mode is a default presentation mode, the intelligent terminal may be set to directly determine that the currently acquired context data is different from the context data acquired in the previous acquiring cycle, or may be set to obtain another determining result, which is not limited herein. 
     If the intelligent terminal determines that the context data does not change compared with the context data acquired in the previous acquiring cycle, the intelligent terminal may also wait for a preset time, and then step  202  is triggered, which is not limited herein. 
       204 : The intelligent terminal identifies a user use scenario according to the context data. 
     When the intelligent terminal acquires the context data, and determines that the context data is different from the context data acquired in the previous acquiring cycle, the intelligent terminal identifies the user use scenario according to the context data, where the user use scenario is used to indicate a scene in which the user currently uses an intelligent device. 
     There are many manners in which the intelligent terminal identifies a user use scenario according to context data. The intelligent terminal may search for scenario configuration information, to obtain a user use scenario corresponding to the context data, where the scenario configuration information includes a correspondence between a context data threshold range and the user use scenario, the intelligent terminal may identify a user use scenario in a machine learning manner, for example, establish a corresponding scenario model M for each scenario A by using a specific quantity of training data sets, including data acquired from a context data source, and a current user use scenario, when a set of data S is acquired from the context data source, S is entered into the model M, and output of M is determining whether the use scenario is the scenario A, and further, by continuously acquiring context data and user use scenario information, the intelligent terminal may learn to update a scenario model, or the intelligent terminal may search for other information, to obtain the user use scenario corresponding to the context data, which is not limited herein. 
     The user use scenario may include a scenario that can be identified according to the context data, for example, a battery level being insufficient, a surrounding environment being noisy, moving outdoors, or being static outdoors, which is not limited herein. 
       205 : The intelligent terminal determines a first presentation mode, which corresponds to the user use scenario, of a presentation mode. 
     After identifying the user use scenario, the intelligent terminal determines the first presentation mode, which corresponds to the use scenario, of the presentation mode, where the presentation mode indicates a content presentation mode. 
     It should be noted that, the presentation mode may include a mode that can be used to present content, such as screen switching, switching to large screen display, projection display, holographic display, and voice broadcast, which is not limited herein. 
     There are multiple methods for the intelligent terminal to determine the first presentation mode corresponding to the user use scenario. The intelligent terminal may search a preset rule policy, to obtain the first presentation mode corresponding to the user use scenario. There may be multiple user use scenarios identified by the intelligent terminal according to the context data. Therefore, policies in the preset rule policy may have different priorities. The intelligent terminal performs sequential matching between multiple identified user use scenarios and the preset rule policy according to the priorities in sequence. When one user use scenario thereof succeeds in matching, the intelligent terminal may use a presentation mode corresponding to the user use scenario as the first presentation mode. For example, a preset rule policy is shown in the following Table 1, where a policy with a relatively small sequence number has a relatively high priority:

     As shown in Table 1, if the multiple identified user use scenarios include the battery level being insufficient or the surrounding environment being noisy, the intelligent terminal does not perform matching for another policy, and determines that the first presentation mode is the screen presentation, or if the multiple identified user use scenarios do not include the battery level being insufficient or the surrounding environment being noisy, the intelligent terminal performs sequential matching for a policy with a relatively low priority, for example, if the scenario of moving outdoors is identified, it is determined that the first presentation mode is the voice broadcast. 
     It may be understood that, the preset rule policy may be preset by the intelligent terminal, or may be customized by the user according to an actual case of the user, or the preset rule policy may be generated by collecting, in a machine learning manner, history use information of the user, or a presentation mode that the user chooses to use in a current user use scenario may be recorded, and then a correspondence between the user use scenario and the presentation mode that is chosen to be used may be updated to the preset rule policy, or the preset rule policy may be obtained in another manner, which is not limited herein. 
     It may be understood that, in some simplified cases, for example, both a quantity of user use scenarios and a quantity of presentation modes are relatively small, the intelligent terminal may also directly determine, according to context data, a presentation mode corresponding to the context data, which is not limited herein.

     When the intelligent terminal determines the first presentation mode corresponding to the user use scenario, the intelligent terminal presents the content to the user in the first presentation mode. 
     When the first presentation mode is a three-dimensional (3D) holographic display, the intelligent terminal may convert a to-be-presented two-dimensional (2D) image into a 3D image, and restore a 3D holographic image by using a built-in slide show program and an optical lens, or when the first presentation mode is projection display, the intelligent terminal may adjust a focal length and a direction of projection, the focal length adjustment is related to a distance between the intelligent terminal and a projection screen, and by means of the direction adjustment, projection may be switched between horizontal or vertical display. 
     In this embodiment of the present disclosure, when content needs to be presented, an intelligent terminal first presents the content to a user in a second presentation mode, after acquiring context data, determines whether the context data changes compared with context data acquired in a previous acquiring cycle, and if the context data changes, performs a subsequent operation by using the current acquired context data, or if the context data does not change, may acquire the context data again. In this way, the intelligent terminal can update the context data in real time, and provide a presentation mode that is most suitable for a current use scenario of the user to the user.

     When an intelligent terminal receives a request for a video call, a pre-presentation module  405  presents content to a user in a screen display manner, an acquiring module  401  acquires context data, to obtain information about a surrounding device and location information of the user, a change judgment module  4021  determines that the context data changes compared with context data acquired last time, an identification unit  4022  identifies, according to the context data, that a current use scenario of the user is that it is a static state and there is a surrounding large screen display device, a presentation determining module  403  determines that a first presentation mode, which corresponds to the user use scenario, of a presentation mode is sending content to a large screen for display, and a content presentation module  404  presents the video call to the user in a manner of sending content to a large screen for display. 
     The following describes a content presentation mode push method in an embodiment of the present disclosure. Referring to  FIG.  6   , an embodiment of a content presentation mode push method in the embodiments of the present disclosure includes: 
       601 : An intelligent terminal acquires context data of a user. 
     When the intelligent terminal is in a powered-on state, the intelligent terminal can acquire the context data of the user. 
       602 : The intelligent terminal identifies a user use scenario according to the context data. 
     After acquiring the context data, the intelligent terminal may identify the user use scenario according to the context data, where the user use scenario is used to indicate a scene in which the user currently uses an intelligent device. 
       603 : The intelligent terminal determines a corresponding presentation mode of the user use scenario. 
     After identifying the user use scenario, the intelligent terminal determines the corresponding presentation mode of the user use scenario, where the corresponding presentation mode includes at least one presentation mode, and the presentation mode indicates a content presentation mode. 
       604 : The intelligent terminal pushes the corresponding presentation mode to the user. 
     After determining the corresponding presentation mode, the intelligent terminal pushes the corresponding presentation mode to the user, so that the user selects a presentation mode from the pushed corresponding presentation mode to perform content presentation. 
     In this embodiment of the present disclosure, after determining a corresponding presentation mode according to context data, an intelligent terminal pushes the corresponding presentation mode to a user for selection, so that the user can independently select a required presentation mode from a suitable presentation mode to perform content presentation, thereby improving user experience. 
     In an actual application, the intelligent terminal may further detect the selection by the user, and perform subsequent processing according to a selection result. Referring to  FIG.  7   , another embodiment of a content presentation mode push method in the embodiments of the present disclosure includes: 
       701 : An intelligent terminal acquires context data of a user. 
     When the intelligent terminal is in a powered-on state, the intelligent terminal can acquire the context data of the user. 
     The context data may also be referred to as context information, and refers to information such as a history record of a location, an action, and a behavior of the user. The context data may be obtained from various pieces of source information, for example, a light sensor may be invoked to detect light intensity, a camera may be invoked to detect a surrounding medium available for projection, a microphone may be invoked to detect intensity of use environment noise, a motion sensor may be invoked to detect moving state data of the user, a GPS or WiFi may be invoked to identify location information of a current user, or a battery management unit may be invoked to detect a current battery level, which is not limited herein. 
     In summary, the context data reflects some attribute information related to the user. 
     The intelligent terminal may be set to acquire the context data once at a specific interval, a preset condition may be set to trigger acquisition of the context data, or the context data may be continuously acquired, which is not limited herein. 
       702 : The intelligent terminal identifies a user use scenario according to the context data. 
     After acquiring the context data, the intelligent terminal may identify the user use scenario according to the context data, where the user use scenario is used to indicate a scene in which the user currently uses an intelligent device. 
     There are many manners in which the intelligent terminal identifies a user use scenario according to context data. The intelligent terminal may search for scenario configuration information, to obtain a user use scenario corresponding to the context data, where the scenario configuration information includes a correspondence between a context data threshold range and the user use scenario, the intelligent terminal may identify a user use scenario in a machine learning manner, for example, establish a corresponding scenario model M for each scenario A by using a specific quantity of training data sets, including data acquired from a context data source, and a current user use scenario, when a set of data S is acquired from the context data source, S is entered into the model M, and output of M is determining whether the use scenario is the scenario A, and further, by continuously acquiring context data and user use scenario information, the intelligent terminal may learn to update a scenario model, or the intelligent terminal may search for other information, to obtain the user use scenario corresponding to the context data, which is not limited herein. 
     The user use scenario may include a scenario that can be identified according to the context data, for example, a battery level being insufficient, a surrounding environment being noisy, moving outdoors, or being static outdoors, which is not limited herein. 
       703 : The intelligent terminal determines a corresponding presentation mode of the user use scenario. 
     After identifying the user use scenario, the intelligent terminal determines the corresponding presentation mode of the user use scenario, where the corresponding presentation mode includes at least one presentation mode, and the presentation mode indicates a content presentation mode. 
     It should be noted that, the presentation mode may include a mode that can be used to present content, such as screen switching, switching to large screen display, projection display, holographic display, and voice broadcast, which is not limited herein. 
     There are multiple methods for the intelligent terminal to determine a corresponding presentation mode of a user use scenario. The intelligent terminal may search a preset rule policy, to obtain the corresponding presentation mode of the user use scenario, where the preset rule policy is used to indicate a correspondence between the user use scenario and the presentation mode. 
     There may be multiple user use scenarios that are determined by the intelligent terminal according to context data. Policies in the preset rule policy may have different priorities. The intelligent terminal performs sequential matching between multiple identified user use scenarios and the preset rule policy according to the priorities in sequence. Sequences of priorities of matching presentation modes are used as sequences of display in corresponding presentation modes. A preset rule policy shown in Table 1 is used as an example, where a policy with a relatively small sequence number has a relatively high priority. 
     As shown in Table 1, if the multiple identified user use scenarios include the battery level being insufficient or the surrounding environment being noisy, and are states of moving outdoors, the intelligent terminal sequentially pushes corresponding presentation modes being screen display and voice broadcast. 
     In addition, after step  705 , that is, the intelligent terminal detects the presentation mode that the user chooses to use, the intelligent terminal may record the presentation mode that the user chooses to use in the user use scenario, and then update, to the preset rule policy, a correspondence between the user use scenario and the presentation mode that is chosen to be used, or the preset rule policy may be obtained in another manner, which is not limited herein. 
     It may be understood that, in some simplified cases, for example, both a quantity of user use scenarios and a quantity of presentation modes are relatively small, the intelligent terminal may also directly determine a corresponding presentation mode of context data according to the context data, which is not limited herein. 
       704 : The intelligent terminal pushes the corresponding presentation mode to the user. 
     After determining the corresponding presentation mode, the intelligent terminal pushes the corresponding presentation mode to the user, so that the user selects a presentation mode from the pushed corresponding presentation mode to perform content presentation. 
       705 : The intelligent terminal detects whether the user chooses to use the corresponding presentation mode. 
     After pushing the corresponding presentation mode to the user, the intelligent terminal detects whether the user chooses to use the corresponding presentation mode, and if the user chooses to use at least one presentation mode of the corresponding presentation mode, step  706  is triggered, or if the user chooses not to use the corresponding presentation mode, step  707  is triggered. 
     The intelligent terminal receives a selection operation by the user in multiple manners. A selection of the user may be determined by identifying a language of the user, or a selection of the user may be received by means of a pushbutton or a touchscreen, which is not limited herein. 
       706 : The intelligent terminal presents content to the user in the presentation mode that the user chooses to use. 
     When the user chooses to use the at least one presentation mode of the corresponding presentation mode, the intelligent terminal presents the content to the user in the presentation mode that the user chooses to use. 
       707 : The intelligent terminal presents content to the user in a default presentation mode. 
     When the user chooses not to use the corresponding presentation mode, the intelligent terminal presents the content to the user in the default presentation mode. 
     It may be understood that, the default presentation mode may be customized by the user, or may be preset before delivery, which is not limited herein. 
     In this embodiment of the present disclosure, an intelligent terminal detects a presentation mode that a user chooses to use in a current user use scenario, and updates a correspondence between the user use scenario and the presentation mode to a preset rule policy, so that the corresponding presentation mode determined by the intelligent terminal can better meet a requirement of the user for a presentation mode.

Further, by using continuously acquired context data and scenario notation information, a system can learn to update a scenario model, thereby increasing accuracy of identifying a use scenario. 
     The display policy setting module  1003  is configured to set and store correspondences between user use scenarios and intelligent terminal display modes. In an initial condition, the system provides a default display policy setting, and additionally, the user may modify and update a display policy according to a requirement and a preference of the user by using input of the policy setting module. In addition, by using a display mode selection that is currently fed back by the user and that is recorded by the display mode recommendation and control module  1004 , the display policy setting module  1003  updates and adjusts a display mode corresponding to a currently identified scenario to a corresponding display mode that is fed back and selected by the user. 
     Table 1 shows some possible examples of display policies. Table 1 includes eight definitions of display mode policies, where a policy with a relatively small sequence number has a relatively high priority. When identifying multiple use scenarios, the system performs sequential matching between the multiple identified scenarios and a display policy table in sequence according to sequence numbers of the display policies. When one scenario thereof succeeds in matching, a corresponding display mode recommended by the system can be obtained. 
     As shown in Table 1, in cases of the battery level being insufficient and the surrounding environment being noisy, a scenario identified according to other context is temporarily not considered, and a screen display mode is preferentially considered. Another display policy is considered only when the foregoing use scenarios do not exist, for example, when it is detected that a user is moving outdoors, a presentation mode of voice broadcast is used, or if it is detected that a user is in a static state outdoors, a screen presentation mode is used. When a scenario in which a user is indoors is detected, whether there is an available large screen display device in a surrounding environment is preferentially determined. If the device exists, an intelligent terminal sends to-be-presented content to the large screen display device for presentation to bring relatively good visual experience to the user. If the device does not exist, whether the user is in a moving state is determined. If the user is in the moving state, content presentation is performed in a manner of voice broadcast. If the user is static, whether there is a surrounding projection medium available (such as a desk or a wall) is further determined. If there is the medium, presentation is performed in a projection manner, otherwise, content is presented in a 3D holographic display manner. 
     The display mode recommendation and control module  1004  performs, according to the display policy stored in the display policy setting module  1003 , matching between the current user use scenario identified by the scenario identification module  1002  and the display policy according to matching priorities, selects a display mode corresponding to the current use scenario as a preferred display manner, presents and recommends the preferred display manner to the user by using the UI  1005 , and controls, according to information that is received by the UI and that is about whether the recommended display mode is used for a user feedback, a corresponding display unit in the display module  1006  to present content. 
     In one embodiment, when there is only one recommended display mode, an intelligent terminal prompts, to a user in a voice manner, an available display mode that is currently recommended, and inquires a user whether to present content in the mode, or when there are multiple recommended display modes, an intelligent terminal presents all recommended display modes to a user in a manner of screen display, and receives a selection of the user. 
     In one embodiment, the display mode recommendation and control module  1004  may provide multiple display modes simultaneously that are currently available and that are obtained by a user by performing matching between a context and a display policy, perform presentation according to a specific priority, for the user to select a most suitable display mode to display to-be-presented content, and send a selection, which is fed back by the user, to the policy setting module  1003 , to update a display policy corresponding to a currently identified scenario. In a case in which multiple display modes are recommended, a preferred UI is a selection interface of a touchscreen. 
     The UI  1005  is used for interaction between an intelligent terminal and a user. An optional UI manner includes a voice command manner, a touchscreen manner, a manner of selection by means of a pushbutton, or the like. Preferably, an intelligent terminal prompts, to a user in a voice manner, an available display mode that is currently recommended, inquires the user whether to present content in the mode, and receives, identifies, and parses a voice command of the user, or acquires feedback information of the user by receiving a selection by means of a pushbutton or a touchscreen. 
     The display module  1006  includes at least two display units of a display screen unit, a projection unit, a holographic display unit, and a voice play unit. 
     The 3D holographic display unit converts a to-be-presented 2D image into a 3D image by using a holographic image processing program, and restores a 3D holographic image by using a built-in slide show program and an optical lens, so that the user obtains more real liveness. 
     In addition, the projection unit may further adjust a focal length and a direction of projection, and the focal length adjustment is related to a distance between a cell phone and a projection screen. By means of the focal length adjustment, a clearest image can be obtained at any distance within a projection range. By means of the direction adjustment, projection may be switched between horizontal or vertical display.
