Specific embodiment
For the technology contents of technical solution, construction feature, the objects and the effects are described in detail, below in conjunction with specific reality
It applies example and attached drawing is coordinated to be explained in detail.
Referring to Fig. 1, for a kind of method for breaking through realistic space limitation of the present invention, arbitrary virtual reality can be run on
VR equipment, includes the following steps, S100 receives real displacement information x, receives reality and turns to angle information α, S102 by the reality
Displacement information or reality turn to angle information and carry out obtaining virtual displacement information after scaling, virtually turn to angle information；S104 will be virtual
In displacement information, virtual steering angle information MAP to Virtual Space.In practical application example, real displacement information is virtual reality
Equipment detects the information of user's displacement in reality, such as it may be half meter to one meter etc. that user, which has walked the display displacement of a step,
Deng the displacement information of virtual displacement information, that is, Virtual Space, generally by virtual portrait height (height of eye) and virtual reality head
It wears equipment and detects that height etc. than determining, determines that length is easier in an embodiment of the present invention using itself as reference system from the ground
It describes the problem.Reality turns to angle information, that is, virtual reality device towards the variable between angle, such as α may be after turning round
Positive and negative 180 ° etc..
Receiving real displacement information and receiving the step of reality turns to angle information to be sampled by setting in the method
Rate or sampling time or sampling threshold realize, sample rate, sampling time of this method etc. not necessarily with virtual reality device
Sampling time is equal.Since the change being positioned against is a continuous process, displacement in every 0.1S and angle can be set
Deviation turns to angle information as real displacement information, reality, if therefore above-mentioned binomial is zero to be also not meant to user at this
Without any movement in 0.1S sections.It can also set often by specific threshold, such as 0.5m, just using the displacement as real displacement
Information often turns to special angle threshold value, turns to angle information, etc. using the angle as reality if 5 ° of ∠.By the way that x, α are carried out
It is re-mapped after scaling into Virtual Space, virtual reality program can be empty by the way that user is induced to avoid the reality on original direction
Between barrier come achieve the effect that break through display space limitation experience large space.
In a further embodiment, the real displacement information obtains virtual displacement after amplifying by displacement equations coefficient
Information；By carrying out the amplification of real displacement, when user advances several meters in reality, more than ten just can be experienced in Virtual Space
The content of rice has achieved the effect that break through realistic space limitation, after the reality steering angle information is reduced by angle coefficient of reduction
It obtains virtually turning to angle information.The reality turns to angle information and refers to that virtual reality device horizontally toward changes in realistic space
The angle of change；The virtual steering angle information refers to：Virtual host public affairs relative to virtual world scene (third person
Under scene) or virtual host public affairs the visual field relative to virtual world scene (first person scene), in Virtual Space
The angle horizontally rotated centered on hero position.For the ease of discussing to rotate clockwise as positive direction, steering angle letter
The positive axis vertical-horizontal of breath is downwards.By the way that the steering angle in realistic space is reduced so that user is in realistic space
The angle for needing to turn over bigger can be in experiencing virtual space content, can when soon knocking barrier in realistic space
The angle of bigger is turned in time so that user will not knock, in the intuitive embodiment, that is, Virtual Space of a comparison substantially into
The exploration of row straight line, and the constantly pitch of the laps, therefore the present invention program has preferably reached breakthrough reality really of its in realistic space
Space limits, the effect explored on a large scale in Virtual Space.
In other specific embodiments, for further perfect scheme, it is big empty preferably to reach small space experience
Between effect, technical scheme of the present invention can also include step, the range information of user and obstacle be received, according to range information
Determine displacement equations coefficient or angle coefficient of reduction.The range information can come from the monitoring of other equipment, information sharing, this hair
Bright scheme only needs to receive data and to be handled according to data, herein with the range information d of barrier, as shown in Fig. 2,
Circle represents position of the user in realistic space, and arrow is represented towards direction, then d can be virtual reality device to obstacle
The length of perpendicular d of object1Or user is towards the distance d of the nearest barrier in direction3, consider that impact volume can also be it
He most meets the possibility length d of wall soon2Etc., specific selection mode can determine as needed.
In preferred embodiment, in order to preferably achieve the effect that break through realistic space obstacle, it would be desirable to be hit soon
To the required step number that user can be reduced during barrier so that user will not knock barrier, therefore the range information and position
It is negatively correlated to move amplification coefficient, i.e., more remote with obstacle distance, the value of displacement equations coefficient x is smaller, position nearer apart from barrier
It is bigger to move amplification coefficient x.The preferred value range of displacement equations coefficient is 1-3, and the negative correlation can be chosen for example reciprocal
Such as：X=1+c/d, negative exponent x=-dc, negative power exponential function x=-cdEtc., derivative is only needed to be less than zero.Or it can also need
Range information is negatively correlated with angle coefficient of reduction, i.e., more remote with obstacle distance, then angle coefficient of reduction is smaller, to user's actual rotation
Angulation change get over unobvious, the negative correlation can be chosen for it is reciprocal for example：α=1+c/d, negative exponent α=- dc, negative power
Exponential function α=- cdEtc., derivative is only needed to be less than zero.
In a preferred embodiment, in order to mitigate the sense of discomfort brought due to steering angle, adjustment of displacement, coefficient value can be with
It is selected as：
X=c1*ln(D/d)
α=c2*ln(D/d)
Wherein D is constant, the preferably half value of the length of realistic space or width or length and width；c1、c2For constant, reader can be with
It voluntarily adjusts as needed.
The logarithmic function reciprocal for choosing above-mentioned range information d is since logarithmic function is more smooth, and in range information d
Tend to infinitely great when going to zero, meet negatively correlated requirement, after tested effect preferably and the sense of discomfort more unobvious brought,
In our practical application, the value of x can be limited no more than 3, the number that α turns to reality the amplification of angle information can also be limited
Value is no more than 28 degree.It avoids generating more discomforts.
In specific embodiment shown in Fig. 3, it is assumed that virtual world guides user to turn to the right side by feasible computer controlled,
Since actual rotation angle is reduced by this method during at this time user advances in right front, then user can unconsciously turn
A larger angle is crossed, during d more becomes smaller, steering angle will more be amplified, and the run trace of user will
As shown in the figure, after final angle of rotation reaches pi/2, user, at this time can be with without the danger for knocking front wall
Selection is continuing with this method so that user, which continues to turn right in real space, to turn around to go back, and can also select no longer to be applicable in
This method, user can forward continue to explore Virtual Space along wall, and we are applicable in again when the wall for soon encountering right side
Method.It is final as shown in figure 4, user may carry out 4 subslots by facing the wall of 4 weeks changes and finally have rotated 2 π
It spins in situ, the half-circle area of π and half of circular arc of having walked only is had rotated in Virtual Space, and this half-circle area is much larger than
The area of realistic space.Pass through the above method, since the radian advanced in virtual world is more smooth, the rail in realistic space
Mark radian deflects bigger, and more smooth curve can include the exploration domain of a bigger, therefore invention achieves in reality
The limitation of spatial obstacle object is broken through in space, in the automatic change user behavior track of user, it is virtual to explore bigger
The technique effect of world region.
In some other embodiment, angle information can be turned to by reality and increased, subtracted fixed angle and obtain virtual steering angle
Information.
In specific embodiment, by reality turn to angle information reduce to obtain it is virtual turn to angle information for, advance when
Time rotation virtual world, the rotation angle for amplifying virtual world when user's active rotation, i.e., so that virtual host public affairs phase
Rotation angle is reduced for virtual scene.
It can give one example again, it is assumed that user walks in virtual world on a straight road, this road can be endless
It is long.User's virtual world during this section of d close to wall starts to rotate fixed angle according to user location, according to above-mentioned
Definition virtually turns to angle information and is reduced, for example fixed angle turns to angle information according to reality and determines so that virtual to turn
It is decreased to zero always to angle information.The rotation of virtual world has been out-tricked the brain of user, and user is allowed to go to R ' from original R
(such as Fig. 5).Fixed angle can also be set related to the obstacle distance received, closer to barrier, in virtual world
The fixed angle of rotation is bigger, premised on not being easily noticed by the users for fixed angle and sense of discomfort will not be brought to user,
We generally set the value of the fixed angle between 0~28 degree.In this example, user has gone to R ', Yong Hu from R
The virtual angle information that turns in virtual world is always zero, is really drawing small circle in real world, the brain of user is but thought
Oneself walks on this endless road always, has also been reached by the above method and has realized what is roamed in large space in small space
Purpose.
Optionally, the displacement equations coefficient can be generated dynamically determining.In the embodiment shown in fig. 6, computer
Displacement and angular magnification are dynamically generated towards the wall in direction and the distance of user position according to user plane, such as schemed
Shown in 6a, Fig. 6 b.Scheme the relationship that a is distance d and displacement equations coefficient x, d is up to length of side l, and maximum amplification is 3 times.Figure
B is the relationship of distance d and the fixed angle A of gain, and d is up to length of side l, and maximum amplification angle is 28 degree.
Unlike virtual displacement information, the diminution pair of virtual displacement information in Virtual Space with exploring bigger region
Applicable situation is limited, but the virtual scaling for turning to angle information can generate significant be applicable in.It has discussed above virtual
The diminution for turning to angle information enables to user to pass by larger angle in realistic space so as to avoid bumping against with barrier, with
The virtual situation for turning to angle information and being obtained by reality steering angle information amplification of lower discussion.
In the embodiment shown in fig. 7, the method for the present invention further includes step, and void is obtained after reality is turned to angle information amplification
Intend turning to angle information, the reality steering angle information, which can amplify to obtain by angle amplification coefficient, virtually turns to angle information, also may be used
To obtain virtually turning to angle information by increasing fixed angle.
As shown in fig. 7, when virtual reality device detects that reality turns to angle information, angle information is turned to reality and is put
Greatly, in the example simplified, real steering angle is amplified 2 times always, when the real steering angle of user turns during several
When having moved total π, the virtual angle information that turns to has had been rotated by 2 π, and virtual host public affairs continue in Virtual Space to former direction
When exploration, the direction of user actual steering far from barrier in reality, as shown in Figure 7.
In preferred embodiment, this method also detect it is negatively correlated with the range information of barrier and angle amplification coefficient α, i.e., with
Obstacle distance is more remote, then angle amplification coefficient is smaller, and unobvious, the negative correlation are got over to the angulation change of user's actual rotation
It can be chosen for inverse for example：α=1+1/d, negative exponent α=- dc, negative power exponential function α=- cdEtc., when with barrier away from
From it is nearer when, more quickly change virtual scene in steering angle so that user can quickly with the azimuth in Virtual Space
Difference is pulled open, allows user that can preferably achieve the effect that break through realistic space limitation to reversed walking.
In some other specific embodiment, whenever detecting that reality turns to angle information, fixed angle can be increased and obtained
Angle information is turned to virtual, is re-mapped into Virtual Space, after the fixed angle accumulation of multiple stacking reaches π, virtual host
Public affairs can be explored in Virtual Space along certain specific direction, the imperceptible azimuthal variation of user in reality, actually still
The right safely pitch of the laps in realistic space.The specific opportunity that user is allowed to turn to can be reached by the setting of virtual scene, this
It is not necessarily to ensure that user will not be rebuffed, but the setting that can combine the preset path of virtual scene (is such as wriggled under kind method
The similar landform such as corridor, long bridge), induction user keep straight on the rear steering special angle of specific range in Virtual Space, thus
In realistic space to barrier walk about a distance after realizing method angle become backwards to barrier, reach and break through realistic space
Limitation carries out the effect that virtual world space is travelled.
