Specific implementation mode
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.
Here 1 is please see Figure, our method may begin at step, and S103 judges the field range of current character, by field
Object in scape is divided into the visual field object outside object or the visual field, and the object outside the visual field is coordinately transformed by S104.Finally will
The object of coordinate transform is shown in the visual field.In our embodiment, in realistic space (hereinafter referred to as room) range usually
With certain barrier, such as wall, people (hereinafter referred to as user) are in room, avoid its with barrier such as wall into
Row collision is top priority, in order to avoid cause danger.Personage's (hereinafter referred to as role) in Virtual Space if (hereinafter referred to as scene)
Action is linked up with user behavior, then exploration region of the personage in Virtual Space can not be more than the size in room always.People exist
The action behavior for exploring universal time needs to find object of reference, has hearsay to think, allows people to take the air line on snowfield, forest and other places, finally
It will become to make a long circuit.Our Method And Principle is by carrying out the coordinate position of the object of reference in scene not by people
The change noticed, to guide user to be changed the direction of traveling.
In the embodiment shown in Figure 2, clearly illustrate that this method may be brought as a result, user is in each line segment
In be straight line moving, role is as the same in scene, after changing direction of travel every time, user actually in realistic space around
Go an octagon, and it is always straight line with what is be traveling at for oneself, then it is explored far in Virtual Space
It is longer than the path of the room length of side, has achieved the effect that the broader Virtual Space of exploration.In the work carried out through the above way,
Perhaps 45 ° of azimuth is turned over every time also brings along prodigious feeling of unreality or dizziness, but in the extreme embodiment of some,
Such as when room is larger, the space of permission user's steering is more, such as only change 10 degree or so of azimuth every time, it is square
Parallactic angle can also sets itself according to the actual needs, then user then can be complete indeed under the premise of not coming over dizzy
At the exploration of greater room.
In some specific embodiments, method further includes step, and S101 receives user's reality location information, judges reality
Whether the orientation, distance of barrier in space, S102 are turned to according to the orientation of barrier, Distance Judgment, work as judgement
When being turned to, then carry out whether the orientation of barrier, Distance Judgment need to turn to, how turn to, such as at role
When shown position, its left side, right side, front can be detected at a distance from barrier, no matter the method for detection, only need to obtain
To realistic space wall and active user position relationship.Such as in fig. 2 when detection has obtained front obstacle
Relatively, while on the left of it obstacle distance is less than the distance of right side barrier.System judgement can guide user to the right
It turns to.It so can be into being about to be deviating to the right with reference to article coordinate for field so that after user changes back to object of reference in the visual field,
Then the angle after variation moves on.
In the embodiment that one simplifies, we are envisioned that such a virtual scene：Object scene only has pure color
Ground, the chest that is in line of ground general alignment and the sun in the sky, as shown in figure 3, the square of periphery represents role's
Present viewing field, only there are two chest, ground sky and the sun in the visual field.When user's control role, which bows, checks chest A,
It is absorbed in things at the moment, remaining chest is completely in the sun outside the visual field.System is stealthily by remaining chest and the sun at this time
Position coordinates deviate 10 ° to the right.When role checks out chest and later watches the sun attentively again and go on foot towards chest B, user
It has actually turned right in realistic space 10 °, and it oneself is still to take the air line to have no doubt.To which user is in reality
Barrier is avoided in space, certainly, what is explored in virtual scene is similarly the content on straight line, if repeated
The above process, user do not know a small range in realistic space constantly turn to, and we will successfully be longer than reality
The content of the space length of side has been presented to user.Based on above-mentioned principle, the implementer of this patent can provide different game/activities
When rules guide user is seeing where (such as content is not only that son of unpacking more can be that go to gather mushrooms dozen aircraft sees stream
Star has strange beast etc.).This is not that this patent wants the content discussed, we only need to distinguish the object inside and outside the visual field, most
Afterwards to the visual field outside all or part of object of reference carry out coordinate variation, it will be able to complete induction user's pitch of the laps in realistic space
Effect.
In a further embodiment, may have in scene it is multiple with reference to objects, if only single or partly to some
Object of reference is coordinately transformed, and is difficult to accomplish not noticeable, and the selection of best object of reference is also a problem.In order to solve
This problem, the present invention also proposes a kind of optimization method of transformation reference article coordinate, as shown in figure 4, for present in scene
Several objects of reference first carry out step S401 and divide monoid to the object of reference outside the visual field in virtual scene, for different groups, carry out
Step S402 obtains size information, azimuth information, the range information etc. of different object of reference monoids.Here size information refers to joining
According to size of the object group in the visual field, i.e. object of reference edged surface product shared in visual field.Azimuth information refers to ginseng out of sight
According to the angular distance of object and the level orientation on visual field boundary, for looking squarely the visual field, general visual field width is 140 ° or so, then position
In 70 ° clockwise --- 290 ° of object of reference is located at out of sight, and the angular distance with visual field boundary is the difference of orientation angles.Away from
It is referred to reference to article coordinate at a distance from current character from information, it is understood that be the depth of field, usually as the object of scene background
Body has farthest distance, also just has the most deep depth of field.
Then after having divided object of reference monoid, so that it may to select object of reference optimal in this method, step S403 according to
Size information, azimuth information or the range information of object of reference monoid choose best object of reference.
In some embodiments it is possible to choose the maximum object of reference monoid of size parameter, object of reference monoid is bigger, then chooses
The monoid is that the possibility of best object of reference is higher, as having the moon, the woods and house in certain scenes, although single trees is big
It is less than house, but after guild division, the woods monoid of the trees combination with same feature is with maximum angle of visibility
Area, our inventor is in practice, it has been found that people get used to choosing large-scale object work in the visual field after the visual field converts
For the reference of oneself, the maximum object of reference monoid of size parameter is chosen as best object of reference, user can be minimized and experience
Indisposed sense when the virtual world of visual field transformation is explored, enhances the usage experience of user.
In further embodiments, best object of reference can be chosen according to above-mentioned azimuth information, is selected by azimuth information
Best object of reference is there are two condition, and all objects need out of sight in the monoid, and monoid is minimum at a distance from present viewing field.

Farthest object of reference is ceased as best object of reference, and in simplified embodiment, the sun as background is in role's moving process
Position it is almost unchanged, it is believed that the depth of field approximation+∞ of the sun, therefore the range information of the sun is farthest, it is best to choose it
Object of reference carries out azimuthal transformation when to it out of sight, user can be made to be most difficult to discover variation therein, certainly this
When azimuthal transformation only have the component parameters in its horizontal direction to be just of practical significance.Compared to far away background,
User has deeper memory to article at one's side, then such processing can preferably hide, affects use unconsciously
The orientation at family.Preferably achieve the effect that large space is experienced in small space plays.
In some increasingly complex embodiments, the selection of best object of reference can also according to size information, azimuth information,

More than preset value, if being judged as YES, step is carried out, S405 is to other object of reference monoids outside best object of reference, all in accordance with adding
The ratio for weighing assignment score and best object of reference assignment score carries out orientation angular transformation.
3, for best object of reference transformation angle is 10.25 ° are taken with preset value, if the ginseng in field range is 0 ° -90 ° outer
Be more than 3 according to species group, then to not only to carry out 10.25 ° of orientation angular transformation to best object of reference, for other objects of reference,
It is multiplied by 10.25 ° of progress orientation angular transformations all in accordance with the ratio of weighting assignment score and best object of reference.Therefore preferably implementing
In example, azimuth transformation for mula is：
Orientation angular transformation=* 10.25 ° of (object of reference monoid weight score/best object of reference weight score)
