Detailed Description
The technical solution of the present invention will be explained below with reference to the accompanying drawings.
As shown in fig. 1, the present invention provides a display method based on virtual reality technology, which may include the following steps:
s1, calling a plurality of pre-stored virtual reality models from the storage space; wherein each virtual reality model is associated with a corresponding interactive object, and each virtual reality model is associated with first location information on a virtual reality display interface;
the virtual reality technology is a computer simulation system which can create and experience a virtual world, and uses a computer to generate a simulation environment, namely a system simulation of interactive three-dimensional dynamic visual and entity behaviors of multi-source information fusion, so that a user is immersed in the environment. Generally, a virtual reality glasses may be provided. The virtual reality model is simply a model with three-dimensional data built by three-dimensional manufacturing software through a virtual three-dimensional space. The virtual reality model may include, but is not limited to, a virtual reality anatomy model, a virtual reality nervous system model, or a virtual reality terrain map model, among others. Each virtual reality model may also be associated with a plurality of submodels, and each submodel may also be a virtual reality model. For example, the human structure model may be associated with sub-models such as a brain model, a torso model, and a limb model; the terrain map model can be associated with sub-models of hills, basins, plateaus, and the like.
In practical applications, the virtual reality model may be stored in a storage space in advance. When the virtual reality model needs to be displayed, a plurality of pre-stored virtual reality models can be called from the storage space. To facilitate performing operations on the virtual reality models, at least one interactive object may be associated for each virtual reality model. The interactive object may be a virtual key. The virtual keys may be rectangular, circular, oval, etc. Each interactive object is configured to perform a certain operation on the corresponding virtual reality model, where the operation may be a start operation (e.g., start playing video, audio, and other content corresponding to the virtual reality model), a rotation operation (e.g., rotate the virtual reality model according to a certain rule), a zoom-in/zoom-out operation (e.g., zoom in or zoom out the virtual reality model according to a certain ratio), a start operation (e.g., start an application program corresponding to the virtual reality model), or other operations.
A position information may be associated with each virtual reality model, and the position information is used to determine a display position of the corresponding virtual reality model on the display interface. The position information may be a set of coordinates in which the positions of points in the virtual reality model on the display interface may be stored.
Each interactive object may be disposed at a certain position of the display interface (for example, a part of the position may be reserved on the display interface for placing each interactive object), or may be disposed at a certain position corresponding to the virtual reality model, for example, uniformly disposed directly below the virtual reality model, and the interactive object is not overlapped with the region where the virtual reality model is located. Therefore, the model can be prevented from being shielded by the interactive object, and a user can observe the model conveniently. In one embodiment, a coordinate range of each virtual reality model in the user interface may be obtained, and the interactive object may be set according to the coordinate range. For example, the coordinate range of the first model is 10-20 on the abscissa and 15-25 on the ordinate; the coordinate range of the second model is 10-20 in abscissa range and 45-55 in ordinate range, and when the interaction object corresponding to the first model is arranged below the model, the interaction module can be arranged in an area with 10-20 in abscissa range and 25-45 in ordinate range on the user interface. The setting of the interactive object can be carried out when the interactive object leaves a factory, and can also be set by a user according to the use habit. In the initial state, the display attribute of each interactive object can be set to be in an invisible state, so that the influence on the visual experience of a user due to excessive content on a user interface is avoided.
In one embodiment, when a user activates the display system (e.g., powers on), a plurality of virtual reality models that are pre-stored may be invoked. Further, a starting instruction sent by a user can be received, a counter is started to count at the same time, and when the count value of the counter reaches a preset counting threshold value, a plurality of virtual reality models which are prestored are called from a storage space. The count threshold may be 3 seconds, 5 seconds, or the like. By setting the count threshold described above, the user can be given sufficient time to familiarize with the system, adjust the pose, or adjust the device (e.g., virtual reality glasses) for maximum comfort.
S2, respectively displaying each virtual reality model at the corresponding position of the virtual reality display interface according to the first position information; wherein the initial state of the display attribute of each virtual reality model on the virtual reality display interface is visible;
the virtual reality modules may be arranged horizontally or vertically on the user interface, or arranged in M rows and N columns on the user interface, or arranged in other ways on the user interface. A schematic structural diagram of the display interface of an embodiment is shown in fig. 2. In the figure, models one to four represent four virtual reality models. Each virtual reality model called from the storage space can be displayed at a corresponding position of the virtual reality display interface. For example, assuming that the position information in step S1 is a coordinate set in which the position information corresponding to three points A, B, C in the first virtual reality model is stored, and the position information is (x1, y1), (x2, y2), and (x3, y3), the position of the first virtual reality model on the display interface can be determined according to the above-mentioned (x1, y1), (x2, y2), and (x3, y 3).
The initial state of the display properties of the respective virtual reality models on the virtual reality display interface may be set to be visible. The display properties determine whether the respective virtual reality model is visible. When a display attribute of a virtual reality model is visible, the virtual reality model is visible; a virtual reality model is not visible when its displayed properties are hidden. In one embodiment, the display attribute of the interactive object corresponding to each virtual reality model can be set to be hidden in the initial state.
S3, when the first interactive object in the interactive objects is detected to be selected by the sight line selection signal, the display attributes of other interactive objects and the virtual reality models corresponding to the other interactive objects are set to be hidden, and the first virtual reality model corresponding to the first interactive object is moved to the position right in front of the sight line.
If the display attribute of the interactive object corresponding to each virtual reality model is set to be hidden in the initial state, in this step, when it is detected that the sight line interactive signal moves to the area where the first virtual reality model is located, the display attribute of the first interactive object is set to be visible, and when it is detected that the first interactive object is selected by the sight line interactive signal, other interactive objects and the display attributes of the virtual reality models corresponding to the other interactive objects are set to be hidden. By the method, misoperation caused when the user does not need to execute operation but the sight line just passes through the first interactive object can be avoided, and user experience is improved.
Further, if it is detected that the gaze interaction signal moves from the area where the first virtual reality model is located to the area where the second virtual reality model is located, the display attribute of the first interaction object corresponding to the first virtual reality model and the first virtual reality model may be set to be hidden, and the display attribute of the second interaction object corresponding to the second virtual reality model and the second virtual reality model may be set to be visible.
After the first virtual reality model corresponding to the first interactive object is moved to the position right in front of the sight line, an audio file and/or a video file corresponding to the first virtual reality model can be searched from a storage space, and the audio file and/or the video file is played. For example, assuming that the first virtual reality model is a human structure model, after the human structure model is moved to the front of the line of sight, an introduction corresponding to the human structure model can be searched from a storage space, and the introduction can be presented in the form of audio and/or video. In this way, further information about the first virtual model may be facilitated for the user.
In another embodiment, each virtual reality model may be associated with several sub-models. A submodel associated with the first virtual reality model may be retrieved from a storage space, a display attribute of the first virtual reality model is set to be hidden, the submodel is displayed at a preset position of the display interface, and the display attribute of the submodel is set to be visible. For example, assume that the first virtual reality model is a model of a human structure, which in turn may include a brain model, a torso model, a limb model, and so forth. Taking the brain model as an example, the brain model may also be stored in the storage space in advance. When displaying, the brain model can be called from the storage space and displayed. In order to prevent the first virtual reality model from being affected during display, the display attribute of the first virtual reality model may be hidden and the display attribute of the brain model may be visible.
And after the user observes the first virtual reality model, the original display interface can be returned through the first interactive object. Specifically, when it is detected that the first interactive object is selected by the gaze selection signal, the first virtual reality model may be moved to a corresponding position of the virtual reality display interface, and display attributes of other virtual reality models may be set to be visible. The corresponding position referred to here is a position corresponding to the position information associated with the first virtual reality model.
In addition, in order to facilitate the user to observe the first virtual reality model, after the first virtual reality model is moved to the position right in front of the sight line, the first virtual reality model can be amplified according to a preset amplification scale, so that the user can observe the detailed characteristics of the first virtual reality model more clearly. Alternatively, the first virtual reality model may be rotated along a preset central axis at a preset rate. The preset central axis may be a central axis of the first virtual reality model, or a central axis of the display interface. In this way, the user can be facilitated to observe the features of the first virtual reality model at various angles.
According to the technical scheme, the display content is displayed in the form of the virtual reality model, and some abstract three-dimensional concepts can be directly displayed in front of eyes, so that the display mode is more visual, the display effect is better, and the immersion effect is better.
As shown in fig. 3, the present invention provides a display system based on virtual reality technology, which may include:
the calling module 10 is used for calling a plurality of pre-stored virtual reality models from the storage space; wherein each virtual reality model is associated with a corresponding interactive object, and each virtual reality model is associated with first location information on a virtual reality display interface;

Generally, a virtual reality glasses may be provided. The virtual reality model is simply a model with three-dimensional data built by three-dimensional manufacturing software through a virtual three-dimensional space. The virtual reality model may include, but is not limited to, a virtual reality anatomy model, a virtual reality nervous system model, or a virtual reality terrain map model, among others. Each virtual reality model may also be associated with a plurality of submodels, and each submodel may also be a virtual reality model. For example, the human structure model may be associated with sub-models such as a brain model, a torso model, and a limb model; the terrain map model can be associated with sub-models of hills, basins, plateaus, and the like.
In practical applications, the virtual reality model may be stored in a storage space in advance. When the virtual reality model needs to be displayed, a plurality of pre-stored virtual reality models can be called from the storage space. To facilitate performing operations on the virtual reality models, at least one interactive object may be associated for each virtual reality model. The interactive object may be a virtual key. The virtual keys may be rectangular, circular, oval, etc. Each interactive object is configured to perform a certain operation on the corresponding virtual reality model, where the operation may be a start operation (e.g., start playing video, audio, and other content corresponding to the virtual reality model), a rotation operation (e.g., rotate the virtual reality model according to a certain rule), a zoom-in/zoom-out operation (e.g., zoom in or zoom out the virtual reality model according to a certain ratio), a start operation (e.g., start an application program corresponding to the virtual reality model), or other operations.
A position information may be associated with each virtual reality model, and the position information is used to determine a display position of the corresponding virtual reality model on the display interface. The position information may be a set of coordinates in which the positions of points in the virtual reality model on the display interface may be stored.
Each interactive object may be disposed at a certain position of the display interface (for example, a part of the position may be reserved on the display interface for placing each interactive object), or may be disposed at a certain position corresponding to the virtual reality model, for example, uniformly disposed directly below the virtual reality model, and the interactive object is not overlapped with the region where the virtual reality model is located. Therefore, the model can be prevented from being shielded by the interactive object, and a user can observe the model conveniently. In one embodiment, a coordinate range of each virtual reality model in the user interface may be obtained, and the interactive object may be set according to the coordinate range. For example, the coordinate range of the first model is 10-20 on the abscissa and 15-25 on the ordinate; the coordinate range of the second model is 10-20 in abscissa range and 45-55 in ordinate range, and when the interaction object corresponding to the first model is arranged below the model, the interaction module can be arranged in an area with 10-20 in abscissa range and 25-45 in ordinate range on the user interface. The setting of the interactive object can be carried out when the interactive object leaves a factory, and can also be set by a user according to the use habit. In the initial state, the display attribute of each interactive object can be set to be in an invisible state, so that the influence on the visual experience of a user due to excessive content on a user interface is avoided.
In one embodiment, when a user activates the display system (e.g., powers on), a plurality of virtual reality models that are pre-stored may be invoked. Further, a starting instruction sent by a user can be received, a counter is started to count at the same time, and when the count value of the counter reaches a preset counting threshold value, a plurality of virtual reality models which are prestored are called from a storage space. The count threshold may be 3 seconds, 5 seconds, or the like. By setting the count threshold described above, the user can be given sufficient time to familiarize with the system, adjust the pose, or adjust the device (e.g., virtual reality glasses) for maximum comfort.

the virtual reality modules may be arranged horizontally or vertically on the user interface, or arranged in M rows and N columns on the user interface, or arranged in other ways on the user interface. A schematic structural diagram of the display interface of an embodiment is shown in fig. 2. In the figure, models one to four represent four virtual reality models. Each virtual reality model called from the storage space can be displayed at a corresponding position of the virtual reality display interface. For example, assuming that the position information in the calling module 10 is a coordinate set, and the coordinate set stores the position information corresponding to A, B, C three points in the first virtual reality model, which are (x1, y1), (x2, y2) and (x3, y3), the position of the first virtual reality model on the display interface can be determined according to the above (x1, y1), (x2, y2) and (x3, y 3).
The initial state of the display properties of the respective virtual reality models on the virtual reality display interface may be set to be visible. The display properties determine whether the respective virtual reality model is visible. When a display attribute of a virtual reality model is visible, the virtual reality model is visible; a virtual reality model is not visible when its displayed properties are hidden. In one embodiment, the display attribute of the interactive object corresponding to each virtual reality model can be set to be hidden in the initial state.

After the first virtual reality model corresponding to the first interactive object is moved to the position right in front of the sight line, an audio file and/or a video file corresponding to the first virtual reality model can be searched from a storage space, and the audio file and/or the video file is played. For example, assuming that the first virtual reality model is a human structure model, after the human structure model is moved to the front of the line of sight, an introduction corresponding to the human structure model can be searched from a storage space, and the introduction can be presented in the form of audio and/or video. In this way, further information about the first virtual model may be facilitated for the user.
