In the prior art, the height of a user of a virtual reality system is generally determined by prompting the user to take a specific gesture before the game is started. However, in this way, the continuous immersive gaming experience of the user is easily disrupted, and at the same time, some users may be provided with opportunities for cheating, with less accuracy. For example: the user deliberately squats down the height to reduce the struck area of the body, thereby achieving the effect of cheating. Thus, the accuracy thereof is to be improved.
In the embodiment of the present disclosure, firstly, a method for determining a height of a user in a virtual reality system is provided, which overcomes, at least to some extent, the drawback of low accuracy of the method for determining a height of a user in a virtual reality system provided in the prior art.
Fig. 1 shows a flow chart of a user height determination method in a virtual reality system in an exemplary embodiment of the disclosure, where an execution subject of the user height determination method in the virtual reality system may be a server for determining the user height in the virtual reality system.
Referring to fig. 1, a method for determining height of a user in a virtual reality system according to an embodiment of the present disclosure includes the steps of:
step S110, obtaining the height value of the user for multiple times through wearable equipment in the virtual reality system worn by the user;
step S120, in response to the fact that the obtained height value of the user is smaller than the estimated height value, reducing the estimated trust value corresponding to the estimated height value by a preset step length;
step S130, in response to the fact that the estimated trust value corresponding to the estimated height value is smaller than a first preset estimated trust value, replacing the estimated height value with the obtained height value of the user, and resetting the estimated trust value corresponding to the estimated height value;
step S140, in response to the fact that the obtained height value of the user is larger than the estimated height value, increasing a preset step length for the estimated trust value corresponding to the estimated height value;
and S150, determining the estimated height value as the effective height value of the user in response to the fact that the estimated trust value corresponding to the estimated height value is larger than a second preset estimated trust value.
In the technical solution provided by the embodiment shown in fig. 1, a height value of a user is obtained multiple times through a wearable device in a virtual reality system worn by the user; if the obtained height value of the user is smaller than the estimated height value, the estimated trust value corresponding to the estimated height value is reduced by a preset step length, when the estimated trust value corresponding to the estimated height value is smaller than a first preset estimated trust value, the estimated height value is replaced by the obtained height value of the user, and the estimated trust value corresponding to the estimated height value is reset, so that the intelligent degree of height determination of the user can be improved; and when the estimated trust value corresponding to the estimated height value is greater than a second preset estimated trust value, determining the estimated height value as an effective height value of the user, so that the accuracy of determining the height of the user can be improved, and the intelligence degree of determining the height of the user can be further improved.
The following describes the specific implementation of each step in fig. 1 in detail:
in step S110, a height value of the user is obtained multiple times through a wearable device in the virtual reality system worn by the user.
In an exemplary embodiment of the present disclosure, step S110 shown in fig. 1 is step a.
In an exemplary embodiment of the present disclosure, a virtual reality system is a technical means relating to the field of graphic images, also referred to as a smart environment or an artificial environment. The virtual reality technology is a computer simulation system which can create and experience a virtual world, and generates the virtual world of a three-dimensional space by using a computer to provide simulation of senses of vision, hearing, touch and the like for a user. Through the virtual reality system, the user can experience the situation and without limitation and observe objects in the three-dimensional space, and further game immersion experience of the user can be improved.
In exemplary embodiments of the present disclosure, a wearable device, i.e., a portable device worn directly on the body or integrated into the clothing or accessories of a user, may implement powerful functions through software support, data interaction, cloud interaction, and the like. For example, the wearable device may be glasses, a head-mounted display, and the like, and the height value of the user may be acquired through the wearable device.
In an exemplary embodiment of the present disclosure, the user may be a game player of a virtual reality system.
In an exemplary embodiment of the present disclosure, the height value of the user may be obtained multiple times at a preset time interval by detecting a size of a wearable device in a virtual reality system worn by the user from the ground. For example, the height value of the user may be obtained by detecting the height of the user's head mounted display from the ground every one second. The specific preset duration can be set according to the actual situation, and the method belongs to the protection scope of the disclosure. For example, the height values of the user acquired multiple times every one second may be 168 centimeters, 171 centimeters, 172 centimeters, 175 centimeters, 173 centimeters, 172 centimeters, 170 centimeters, 173 centimeters.
In an exemplary embodiment of the present disclosure, after the height value of the user is obtained, a height value smaller than the effective height threshold may be filtered, for example, the effective height threshold may be a value preset by the system, for example, the effective height threshold is set to 120 cm. That is, if the height value of the user is 100 cm and 100 cm is less than 120 cm, 100 cm is filtered out, and the height value of the user is obtained again. Through setting up effective height threshold value, can solve the user and deliberately low height of squatting in prior art to reduce the technical problem of self struck area, cheating, simultaneously, can also exclude the error data of non-human height automatically, improved the definite degree of accuracy of user's height.
In step S120, in response to that the obtained height value of the user is smaller than the estimated height value, the estimated trust value corresponding to the estimated height value is decreased by a preset step length.
In an exemplary embodiment of the present disclosure, step S120 shown in fig. 1 is step B.
In an exemplary embodiment of the present disclosure, the estimated height value is a preset height value, and for example, the estimated height value may be an average height of a human, so as to reduce the amount of calculation and improve the data processing efficiency. The estimated height value may be 170 centimeters, for example.
In an exemplary embodiment of the disclosure, if the obtained height value of the user is smaller than the estimated height value, the estimated trust value corresponding to the estimated height value may be decreased by a preset step length. For example, the initial value of the estimated trust value corresponding to the estimated height value may be 0, and the preset step size may be 1. It should be noted that, the specific value of the initial value and the specific value of the preset step length may be set according to actual situations, and belong to the protection scope of the present disclosure.
In an exemplary embodiment of the disclosure, when the obtained height value of the user is smaller than the estimated height value, the estimated trust value corresponding to the estimated height value may be decreased by a preset step length. Referring to step S110 and the above-mentioned related explanation, the height value of the user obtained for the first time is 168 cm, and 168 is smaller than the estimated height value 170 cm, so that the estimated trust value (0) corresponding to the estimated height value (170 cm) can be reduced by the preset step length (1), and the estimated trust value corresponding to the estimated height value (170) is known to be-1.
In step S130, in response to the estimated trust value corresponding to the estimated height value being less than a first preset estimated trust value, replacing the estimated height value with the obtained height value of the user, and resetting the estimated trust value corresponding to the estimated height value.
In an exemplary embodiment of the present disclosure, step S130 shown in fig. 1 is step C.
In an exemplary embodiment of the present disclosure, for example, the first preset estimated trust value may be set to 0, and the specific value may be set according to the actual situation, which belongs to the protection scope of the present disclosure.
In an exemplary embodiment of the disclosure, if the estimated trust value corresponding to the estimated height value is smaller than the first preset estimated trust value, the estimated height value may be replaced with the obtained height value of the user, and the estimated trust value corresponding to the estimated height value may be reset. For example, referring to the related explanation of step S120, the estimated confidence value corresponding to the estimated height value 170 is-1, and-1 is smaller than the first preset estimated confidence value 0, so that the estimated height value may be replaced with the obtained height value 168 cm of the user, and meanwhile, the estimated confidence value corresponding to the estimated height value 168 is reset to the initial value 0.
In step S140, in response to that the obtained height value of the user is greater than the estimated height value, increasing the estimated trust value corresponding to the estimated height value by a preset step length.
In an exemplary embodiment of the present disclosure, step S140 shown in fig. 1 is step D.
In an exemplary embodiment of the disclosure, if the obtained height value of the user is greater than the estimated height value, the estimated trust value corresponding to the estimated height value may be increased by a preset step length. For example, referring to the related explanations of step S110 to step S130, when the obtained height value of the user is 171 cm, and 171 cm is greater than 168 cm, the estimated trust value 0 corresponding to the estimated height value 168 may be increased by a preset step size 1, and then the estimated trust value corresponding to the estimated height value 168 may be obtained as 1.
In step S150, in response to the estimated confidence value corresponding to the estimated height value being greater than a second preset estimated confidence value, the estimated height value is determined as the effective height value of the user.
In an exemplary embodiment of the present disclosure, step S150 shown in fig. 1 is step E.
In an exemplary embodiment of the present disclosure, the second preset estimated trust value is a value greater than the first preset estimated trust value, for example, may be 6, and a specific value of the second preset estimated trust value may be set according to an actual situation, which belongs to the protection scope of the present disclosure.
In an exemplary embodiment of the present disclosure, the estimated height value may be determined as an effective height value of the user when the estimated confidence value corresponding to the estimated height value is greater than a second preset estimated confidence value. For example, referring to the related explanations of step S110 and step S140, after determining that the estimated trust value corresponding to the height value 168 is 1, when the height value of the user is 172 cm and 172 cm is greater than 168 cm, the preset step size may be added to the estimated trust value corresponding to the estimated height value 168, so as to determine that the estimated trust value corresponding to the estimated height value 168 is 1+1 — 2. Further, when the obtained height of the user is 175 cm, and similarly 175 cm is larger than 168 cm, it may be determined that the estimated trust value corresponding to the estimated height value is 2+1 — 3. Further, if the acquired height values of the user are 173 cm, 172 cm, 170 cm, and 173 cm, respectively, and it is found that the four height values of 173 cm, 172 cm, 170 cm, and 173 cm are all larger than the estimated height value 168 cm by referring to the above explanation, it is finally determined that the estimated confidence value corresponding to the estimated height value 168 cm is 3+1+1+1 — 7. It is readily appreciated that the estimated confidence value 7 for the height value 168 centimeters is greater than the second predetermined estimated confidence value 6, and thus, the estimated height value 168 may be determined as the effective height value for the user.
In an exemplary embodiment of the present disclosure, after the effective height value of the user is determined, the processes described in the above steps S110 to S150 (i.e., step a, step B, step C, step D, and step E) may be cyclically executed, so as to update the effective height value of the user in real time according to the obtained height value of the user, thereby further improving the accuracy of determining the height of the user, enabling a game scene to be more truly displayed, and improving the game experience of the user.
In an exemplary embodiment of the present disclosure, after the effective height value of the user is determined, the virtual object in the virtual reality system may be displayed according to the effective height value of the user and a preset display scale. For example, the preset display scale may be, the effective height value of the user: the display height of the virtual object is 2: 1, for example: when the effective height value of the user is determined to be 168 cm, according to 2: 1, it is possible to display a virtual object in the virtual reality game having a height of 84 cm. The specific display scale can be set according to the actual situation, and belongs to the protection scope of the disclosure.
The present disclosure also provides a user height determining apparatus in a virtual reality system, and fig. 2 shows a schematic structural diagram of the user height determining apparatus in the virtual reality system in an exemplary embodiment of the present disclosure; as shown in FIG. 2, a user height determination apparatus 200 in a virtual reality system can include an acquisition module 201, a first response module 202, a second response module 203, a third response module 204, and a third response module 205.
