< method examples >
Fig. 2 is a flowchart of a control method for a virtual reality scene according to an embodiment of the present invention. As shown in fig. 2, the method for controlling a virtual reality scene provided in this embodiment may include:
Specifically, the interactive reference object is a scene object, such as a vehicle, disposed in a virtual reality scene and serving as a visual reference object of a user, which can provide a human-computer interaction experience in response to a user operation, and is used for providing the user with an experience of being carried and moved in the virtual reality scene. More specifically, the vehicle may be a cable car, a rail car, a boat, etc., which are not enumerated herein. In one example, as shown in fig. 3, the vehicle is a rope car, which can move in the virtual reality scene in response to the movement operation of the user, and provides the experience that the user is carried to move in the virtual reality scene.
And step 220, responding to the operation of the user for moving the interactive reference object, moving the interactive reference object in the virtual reality scene, and acquiring the moving speed of the interactive reference object.
The operation of moving the interactive reference object by the user can be realized by operating the handle. For example, in the virtual reality scene shown in fig. 3, the interactive reference object is a rope car, and the user wants to move the rope car, can hold the handle and press a control key, such as a Fire key, to implement an operation of moving the rope car, which is mapped to the virtual reality scene that the user pulls the rope of the rope car backwards, so as to implement that the rope of the rope car in the virtual reality scene is dragged to move the rope car forwards.
It should be noted that the moving speed of the interactive reference object is the moving speed of the virtual reality scene picture. The moving speed can be calculated by sampling the moving distance and the moving time of the interactive reference object in the virtual reality scene. Specifically, the moving speed of the cross reference object is the ratio of the moving distance and the moving time obtained by sampling.
For example, in the case that the interactive reference object is a cable car, the moving speed of the cable car is obtained, specifically, the starting position of the cable car in the virtual reality scene may be recorded when the user presses a Fire key, and the current position and the moving time of the cable car in the virtual reality scene after the user pulls the handle backwards are sampled. And determining the moving distance of the rope car according to the difference value between the current position and the initial position, and determining the moving speed of the rope car in the virtual reality scene according to the ratio of the moving distance of the rope car to the moving time.
And 230, when the moving speed falls into a preset speed range, adjusting the moving speed to deviate from the speed range.
The preset speed range is a speed range in which the user is likely to produce dizziness. When the moving speed of the interactive reference object in the virtual reality scene falls into the preset speed range, the user is easy to feel dizzy. In this embodiment, when the moving speed of the interactive reference object in the acquired virtual reality scene falls within a preset speed range, the moving speed is adjusted to make the moving speed of the interactive reference object deviate from the range, so that the vertigo of the user is reduced.
It is understood that the user's vertigo feeling is low when the moving speed of the picture is slow. When the moving speed of the picture is high, the visual focus of the user leaves the picture moving at high speed and is projected to a low-speed or static object, and the user only keeps watching the picture moving at high speed by visual residual light. Therefore, when the moving speed of the picture is high, the eyes of the user can unconsciously abandon the capture of the object moving at high speed and focus on the low-speed or static object, thereby avoiding dizziness.
Therefore, in this embodiment, the step of adjusting the moving speed to deviate from the speed range may specifically include:
and when the difference value between the moving speed and the lower limit value of the speed range is not greater than a preset down-regulation threshold value, adjusting the moving speed to be smaller than the lower limit value of the speed range.
And when the difference value between the moving speed and the lower limit value of the speed range is larger than a preset down-regulation threshold value, adjusting the moving speed to be larger than the upper limit value of the speed range.
Optionally, when the difference between the moving speed and the lower limit value of the speed range is not greater than a preset down-regulation threshold, multiplying the moving speed by a preset down-regulation factor to obtain an updated moving speed, so as to adjust the moving speed to be smaller than the lower limit value of the speed range; and when the difference value between the moving speed and the lower limit value of the speed range is larger than a preset down-regulation threshold value, multiplying the moving speed by a preset up-regulation factor to obtain an updated moving speed, and realizing the adjustment of the moving speed to be smaller than the lower limit value of the speed range.
It should be noted that the up-regulation factor and the down-regulation factor are set for adapting the sense of the eyes of the user to adjust to the comfortable range of the eyes of the user, and the up-regulation factor and the down-regulation factor can be adaptively adjusted according to the receptivity of different users, so as to reduce the vertigo of the user to the maximum extent.
In one example, visual parameters of a user can be obtained, an upper limit value and a lower limit value of a speed range are set, the receptivity of different users to vertigo feeling is considered, and the virtual reality experience of the user is improved better. Correspondingly, the method for controlling a virtual reality scene provided in this embodiment further includes:
and setting an upper limit value and a lower limit value of the speed range according to the acquired visual parameters.
When a user observes a picture visually, that is, by observing the picture with human eyes, the human eyes can track the movement of the picture. For example, when a user observes a virtual reality scene through a virtual reality device, the eyes of the user track the scene movement of the scene. The visual parameters are parameters reflecting the speed of human eyes tracking the scene when a user visually observes the scene and the scene moves.
In one example, the visual parameters may include a visual focus capture speed, a binocular focusing speed, and a stereo synthesis speed. Specifically, when a user observes a virtual reality scene through human eyes, the vision is attracted by objects appearing in the scene, and the vision focus is located on the object of most interest, if no object which is more interesting to the user exists in the scene, the vision of the user is in a fast patrol state, and the vision focus is changed rapidly at the moment. The capture visual focus speed refers to the tracking speed of the user's eyes from the patrol viewpoint to a point where the eyes fall on the object of interest. And the binocular focusing speed refers to a tracking speed when the focus of the eyes of the user is adjusted to be consistent after the eyes of the user fall on a certain point of the interested object. The stereoscopic synthesis speed is a tracking speed when a user clearly sees a certain point on a screen with both eyes to perform stereoscopic synthesis.
The values of the acquired visual parameters are different according to different virtual reality devices and different users using the virtual reality devices, and therefore the upper limit value and the lower limit value of the speed range set according to the acquired visual parameters are different.
More specifically, the step of setting the upper limit value and the lower limit value of the speed range includes:
setting the upper limit value of the speed range as the sum of the visual focus capturing speed, the binocular focusing speed, the stereo synthesis speed and a preset deviation threshold;
the lower limit value of the speed range is set as the sum of the visual focus capturing speed, the binocular focusing speed, and the stereoscopic synthesis speed.
It can be understood that the lower limit of the speed range is set as the sum of the visual focus capturing speed, the binocular focusing speed and the stereo synthesis speed, and after the moving speed of the interactive reference object falls into the preset speed range, if the difference between the moving speed and the lower limit of the speed range is not greater than the preset down-regulation threshold, the moving speed is adjusted to be less than the lower limit of the speed range, and the dizzy feeling of the user is naturally reduced due to the reduction of the moving speed.
And a preset deviation threshold value is added in the upper limit value of the speed range, after the moving speed of the interactive reference object falls into the preset speed range, if the difference value between the moving speed and the lower limit value of the speed range is larger than a preset down-regulation threshold value, the moving speed is regulated to be larger than the upper limit value of the speed range, so that the moving speed is far larger than the speed which a user can pay attention to, the attention point of the user is enabled to leave the picture moving at high speed, and the dizzy phenomenon is avoided.
Therefore, the control method for the virtual reality scene provided by the embodiment can reduce the dizzy feeling generated when the user watches the moving scenery displayed by the high-speed movement of the scene picture in the virtual reality scene, and improve the virtual reality experience of the user.
