In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

The terms "first", "second", "third" and "fourth" in the specification and claims of this application and the above drawings are used to distinguish different objects, rather than to describe a specific order . Furthermore, the terms "comprising" and "having", and any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, product, or device comprising a series of steps or units is not limited to the listed steps or units, but may include unlisted steps or units.

After introducing the technical solutions of the embodiments of the present invention, various non-limiting implementations of the present application will be described in detail below.

First, referring to FIG. 1, FIG. 1 is a schematic flow chart of a method for adjusting seat parameters of a virtual reality platform provided by an embodiment of the present invention. Embodiments of the present invention may include the following:

S101: Obtain physical parameters of the current user.

The user's physical parameters may include any one or combination of gender, age, height, weight, heart rate, body temperature, and blood pressure; wherein, gender, age, height, and weight are fixed parameters during an experience.

Dynamic physiological parameters are parameters that change with the movement of the virtual reality platform, such as heart rate, body temperature, and blood pressure. Vary with changes in field of view. During the experience of virtual reality games, the value of dynamic physiological parameters can reflect the current user's physical comfort. It may cause discomfort such as dizziness and nausea to the user.

Physical parameters such as gender, age, height, and weight can be obtained from the registration information records registered when the user registers to use the virtual reality platform, and relevant information can also be input before the user experiences. Dynamic physiological parameters such as heart rate, body temperature, and blood pressure can be obtained from It is obtained from information collected by sensors such as wristbands worn by users, and the specific method of obtaining physical parameters is not limited by this application.

S102: Determine the initial movement parameters of the seat of the virtual reality platform and the gain coefficients corresponding to each movement parameter in the pre-established knowledge database according to the body parameters.

The knowledge database stores the corresponding relationship between the user's body parameters, the motion parameters of the virtual reality platform, and the safety thresholds of each dynamic physiological parameter.

The motion parameters of the virtual reality platform may be an angular velocity threshold and an acceleration threshold. Correspondingly, the acceleration also corresponds to an acceleration gain coefficient (acceleration magnification), and the angular velocity also corresponds to an angular velocity gain coefficient (angular velocity magnification).

The process of building a knowledge database may include:

Obtain the movement parameters of the virtual reality platform and the current dynamic physiological parameter values when multiple experience users have different experience effects during the movement of the virtual reality platform;

According to the physical parameters, motion parameters, and dynamic physiological parameter values corresponding to multiple groups of experience users in different experience effects, a user body parameter-platform motion data correspondence table is established.

The body parameter-platform motion data correspondence table shows the platform motion parameter value when the body parameter corresponds to the best effect of user experience. For example, the user's physical parameters are height 180cm, age 18, male, body temperature 37°C, heart rate 80 beats/min, the user's acceleration (m/s ² ) threshold is (5, 10), angular velocity The (rad/s) threshold is (50, 80) for the best experience when exercising, then the corresponding relationship recorded in the body parameter-platform exercise data table is (height (180cm), age (18), male, Body temperature (37°C), heart rate (80 beats/min)-acceleration threshold (5, 10), angular velocity threshold (50, 80)).

The physical parameter-platform motion data correspondence table also records the user's current physical parameter and the corresponding dynamic physiological parameter safety threshold.

In practical applications, according to the obtained body parameters and the data in the body parameter-platform motion data correspondence table, calculations can be made according to the proportional relationship to obtain the platform motion parameter values corresponding to the current body parameters, the gain coefficient of each motion parameter, and the user's dynamic physiological parameters. Parameter safety threshold. The virtual reality platform generates a specific experience process for specific experience users according to the calculated initial motion parameters.

The knowledge database may also include the following model building, specifically:

Obtain the motion parameters of the virtual reality platform and the current dynamic physiological parameter data when multiple experience users have different experience effects during the exercise process of the virtual reality platform;

Use the model training algorithm to train multiple groups of physical parameters, exercise parameters, and dynamic physiological parameters when experiencing different user experience effects, and generate a platform parameter adjustment model; the platform parameter adjustment model outputs the current user's physical parameters or dynamic physiological parameters. Motion parameters and corresponding gain coefficients of the virtual reality platform.

The model training algorithm can be any semi-supervised learning model, fully supervised learning model, or unsupervised learning model such as machine learning model, neural network learning model, and deep learning model. This application does not make any restrictions on this. The specific model training process Reference may be made to the description of the prior art, which will not be repeated here.

It should be noted that in the process of simulating the movement of the real platform, the values of dynamic physiological parameters can be input into the trained model in real time, and the movement parameters of the current platform can be obtained, which can be adjusted according to the output movement parameters. Of course, the platform motion parameters can also be adjusted through the platform parameter adjustment model according to the current user's physical parameters or the gain coefficient output by the dynamic physiological parameters, which will not affect the implementation of the present application.

The knowledge database is not static and can be continuously updated and expanded by obtaining more experience user data and game parameter data through various channels. Developers can also regularly update the knowledge database of seat platform equipment on the market to keep it up-to-date state. In a specific implementation manner, the updates may be performed according to the acquired body parameters of the experience user and the corresponding motion parameters during different experience effects according to a preset frequency.

S103: Acquiring the dynamic physiological parameter value of the user in real time during the movement of the virtual reality platform according to the initial movement parameter.

S104: Adjust the motion parameters of the seat and the user's screen view parameters according to the value of the dynamic physiological parameter, the safety threshold of the dynamic physiological parameter, and each gain coefficient.

After obtaining the initial movement parameters of the seat of the virtual reality platform in S102, a specific experience process is generated for the current user according to the initial movement parameters, and the virtual reality platform starts to move according to the initial movement parameters.

During the movement of the virtual reality platform, that is, in the process of the user experiencing the virtual reality game, the seat will perform corresponding multi-degree-of-freedom movements such as forward, backward, flip, and pitch according to the specific scene of the game. The user experiences different exercise intensities. In order to improve the user's dizziness and increase the time for the user to experience the virtual reality game, the user's dynamic physiological parameter information can be collected in real time during the user experience process, and the intensity of the game can be adjusted according to the value of the dynamic physiological parameter.

In providing users with a comfortable body feeling, it includes both the motion data of the platform and the picture data presented to the user. Among them, the field of view (FOV) of the picture presented to the user will have a relatively large impact on the user's experience intensity. Adjust the screen view effect presented to the user by adjusting the screen view parameters. For example, in the process of accelerating forward in the experience game, the motion platform outputs a certain acceleration change correspondingly, and the screen view angle also needs to be adjusted and changed.

The specific process of adjusting the motion parameters of the seat and the user's screen field of view parameters according to the dynamic physiological parameter value, the safety threshold of the dynamic physiological parameter and each gain coefficient may include:

Judging whether the value of each dynamic physiological parameter exceeds the corresponding dynamic physiological parameter safety threshold;

If so, adjust the motion parameters of the seat according to each gain coefficient to reduce the overall motion range of the virtual reality platform, and adjust the user's screen field of view parameters;

If not, determine whether the value of each dynamic physiological parameter is lower than the lower limit of the corresponding experience effect; if so, adjust the motion parameters of the seat according to each gain coefficient to increase the overall motion range of the virtual reality platform and adjust the user's visual field of view parameters; if not, maintain the current motion parameters and screen view parameters.

The dynamic physiological parameter safety threshold is the maximum dynamic physiological parameter value for the user to experience comfortable game effects during the experience of the virtual reality platform. If the safety threshold is exceeded, the current user may experience dizziness, nausea and other uncomfortable somatosensory experiences, and the current exercise should be appropriately reduced. magnitude. Of course, the lower limit of the experience effect can also be set. When the value of the dynamic physiological parameter is lower than the lower limit of the experience effect, the user's experience effect is not good, and the current exercise range can be increased.

Of course, it is also possible to only set the safety threshold of the dynamic physiological parameter without setting the lower limit of the experience effect, which is not limited in this application.

By setting the safety threshold of dynamic physiological parameters and the lower limit of the experience effect, low-intensity users will not experience uncomfortable body sensations such as dizziness and nausea, while high-intensity users can obtain the happiness brought by the ultimate effect.

In the technical solution provided by the embodiment of the present invention, according to the user's physical parameters and dynamic physiological parameter data in the experience process, based on the knowledge storage capacity in the knowledge database, the motion parameters of the virtual reality platform and the picture effects presented to the user are adjusted in real time , for users of different age groups and different physical conditions, adaptively adjust the range of motion during the virtual reality platform experience process, and optimize the user experience effect. For low-intensity users, there will be no uncomfortable body sensations such as dizziness and nausea, while high-intensity More users can get the happiness brought by the ultimate effect, thereby enhancing the user's somatosensory experience and improving user retention.

In virtual reality games, there is generally a game process of simulating extremely fast motion. During this kind of extreme exercise, by challenging the physiological limit to bring the user a stimulating body feeling, the user will experience rapid heartbeat changes in a short period of time. At this time, the specific value of the dynamic physiological parameter may be greater than the safety threshold of the dynamic physiological parameter, but if the adjustment exercise Intensity, the user will not enjoy the stimulating and tense somatosensory experience brought by extreme sports. In view of this, this application provides another embodiment based on the above-mentioned embodiment. Please refer to Figure 2, which may specifically include:

S201-S203: Specifically, it is the same as the description of S101-S103 in the foregoing embodiment, and will not be repeated here.

S204: Determine whether the current game type experienced by the user is an extreme sports type; if yes, execute S205; if not, execute S206.

S205: Obtain the local gain coefficients of each parameter of the extreme sports type, and adjust the motion parameters of the seat and the screen view parameters displayed to the user according to the value of the dynamic physiological parameters, the safety threshold of the local dynamic physiological parameters and each local gain coefficient;

S206: Obtain the global gain coefficients of each parameter, and adjust the motion parameters of the seat and the visual field parameters of the screen displayed to the user according to the values of the dynamic physiological parameters, the safety thresholds of the dynamic physiological parameters, and each global gain coefficient.

When the virtual reality platform recognizes that the game is running in the extreme sports type, it can obtain the local dynamic physiological parameter safety threshold. The local dynamic physiological parameter safety threshold is greater than the dynamic physiological parameter safety threshold. At this time, if the heartbeat input data is continuously higher than the local dynamic The safety threshold range of physiological parameters, on the one hand, adjust the game output gain (that is, adjust the motion parameters of the seat) to reduce the range of violent motion; on the other hand, adjust the FOV displayed on the user screen. discomfort.

By distinguishing different types of virtual reality games, the user experience can be improved to the greatest extent and user retention can be improved.

In order to further optimize the user's somatosensory experience, based on the above-mentioned embodiments, this application also provides another embodiment, which may specifically include:

Receive user-input comfort feedback information;

Adjust the motion parameters of the seat and the visual field parameters of the screen displayed to the user according to the feedback information of physical comfort.

By providing a human-computer interaction interface on the virtual reality platform, set the user's experience feeling on the human-computer interaction interface, such as exercise intensity (high, low, general) and user comfort (comfortable, poor, dizzy, nausea), etc. A variety of buttons, users can give feedback according to their own experience and tolerance, and the virtual reality platform adjusts the motion parameters of the seat and the screen view parameters according to the information fed back by users.

For example, when receiving user feedback that the exercise intensity is low and the physical comfort is not good, it indicates that the current exercise intensity is low, and the user cannot experience the joyful and exciting feeling brought by virtual games, and the platform can increase the exercise intensity. When receiving user feedback that the comfort level is nausea and dizziness, it indicates that the current exercise intensity is too high, and the platform can reduce the exercise intensity.

By adjusting according to the user's feedback information, the time for users to experience VR is increased, and at the same time, the VR somatosensory experience of different users can be accurately grasped, the experiencer's dizziness can be improved, the user's experience effect can be further optimized, the user's somatosensory experience can be improved, and the user experience can be improved. retention.

In order to better help developers analyze and study the physical conditions of different experiencers adapting to the game, and refine the parameters of acceleration, angular velocity, local gain coefficient and global gain coefficient of different game data, based on the above embodiments, it may also include:

The corresponding relationship between the user's body parameters and the initial exercise parameters, and the corresponding relationship between the user's dynamic physiological parameter values and the adjusted exercise parameter values during the exercise of the virtual reality platform are stored in the knowledge database.

By storing all the experience data of each experience user during the experience process, the physical response data of different experiencers in the experience game is recorded in a targeted manner, such as the experiencer's heartbeat at different stages when experiencing a somatosensory game, The change of body temperature data with the output acceleration and angular velocity curve of the game can increase the knowledge storage data of the knowledge database and improve the accuracy of parameter adjustment, thereby improving the user's somatosensory experience and improving the applicability of the virtual reality platform.

In order to make those skilled in the art more clearly understand the principle of the technical solution of the present application, this application also provides a specific example, which may specifically include:

Take human heartbeat variation parameters as an example. Before experiencing the virtual reality game, the user registers a unique account through the virtual reality platform, and the registration information records the user's height, weight and other parameters. Wearable wristbands and other devices record the specific values of real-time body temperature, heart rate, blood pressure and other dynamic physiological parameters during the user experience process. By obtaining physical parameters such as height, weight, heartbeat, body temperature, and blood pressure, the user's heartbeat safety threshold, body temperature safety threshold, blood pressure safety threshold, initial acceleration threshold, initial angular velocity threshold, acceleration gain coefficient, and angular velocity gain coefficient are confirmed based on the knowledge database table.

After the user starts to experience the game, the real-time heartbeat, body temperature, and blood pressure data are transmitted to the virtual reality platform. According to the match between the heartbeat data and the heartbeat safety threshold data, it is judged whether the heartbeat data exceeds the safety threshold range. When the heartbeat data is less than or floating within the safe range, then Keep the game output motion parameters unchanged. When the heartbeat data is higher than the safe threshold range, adjust the game motion parameters to reduce the overall motion range.

It can be seen from the above that the embodiments of the present invention can improve the user's somatosensory experience and improve user retention.
