As shown in figure 1, the present invention discloses a kind of information processing method, this method may comprise steps of：
S11：When detect holographic projection system Current projection region at least one operating body be present when, obtain with it is described
First predetermined registration operation corresponding at least one operating body.
In the embodiment of the present invention, first content can be projected in the Current projection region of holographic projection system, this first
Content can be the project content with two-dimensional space or three-dimensional spatial distribution presentation.In practical application, first content can include
Multiple project contents, such as animal, personage, plant, landscape.
Optionally, in the embodiment of the present invention, at least one operating body can refer to the hand of user, i.e. both hands.And first
Predetermined registration operation can be the interactive operation that user is carried out in Current projection region.For example, user gos deep into hand in view field,
The action of hand is detected by the sensor of system, such as clenched fist or mobile.
In practical application, first predetermined registration operation can be for controlling at least one operating body the first operating body and with the
Relative status between the second relative operating body of one operating body are switched to the operation of the second state by first state, or, it is
At least one operating body is controlled to switch to the operation of first state by the second state, wherein, relative status can refer to user's hand
Opposite between the palm and pair when state.
Specifically, first state can be that the relative distance between the first operating body and the second operating body is not less than first
The open mode of default relative distance, as the palm of user's both hands is relative and is in parallel relative status, between palm away from
From not less than the first default relative distance, such as 5cm, 10cm.
And relative distance of second state between the first operating body and the second operating body it is default relative no more than second away from
From closure state, as user is closed together by both hands palm, in the present invention, it is default that the second pre-determined distance can be less than first
Relative distance, such as the second pre-determined distance can be 1cm, 2cm.In actual mechanical process, holographic projection system can pass through
Infrared sensor or the first-class sensing equipment with identification function of shooting come detect between the width of user's hand and palm away from

The first predetermined registration operation that i.e. holographic projection system detects can mainly include two kinds, and one kind is gradual for user's both hands
The operation closed up, the operation that another kind gradually opens for the both hands of user in view field.
S12：Determine the first view field corresponding with least one operating body in the Current projection region；Its
In, in first view field in the first project content of the first Spatial Dimension distribution presentation, first projection
Appearance is in the first projection mode.
In the embodiment of the present invention, when holographic projection system is projected first content according to the first projection mode, the
One content in corresponding view field can according to additional space dimension be distributed present projection image, i.e., two-dimensional projection's pattern or
Person tripleplane pattern.
Specifically, determine that the first targeted project content of at least one operating body can be with holographic projection system
It is divided into following two situations.
Situation one：If the first predetermined registration operation is switched to the behaviour of the second state at least one operating body of control by first state
Make, then S12 can specifically include procedure below：
First, first operating body is obtained under the first state at the beginning of first corresponding in the Current projection region
Beginning coordinate, and the second initial coordinate corresponding to second operating body；
Secondly, first initial coordinate and second the initial coordinate corresponding solid space on operation direction are determined
Region, the first project content that the solid space region includes in the first projection mode and presented in three-dimensional spatial distribution；
Then, the solid space region is defined as the first view field corresponding with least one operating body.
Wherein, the first initial coordinate and the second initial coordinate can refer at least one operating body in Current projection region
Corresponding coordinate position.As a rule, in three-dimensional coordinate, initial coordinate can be that the first operating body and the second operating body exist
Corresponding coordinate set in view field.
In actual applications, operation direction can be that operating body turns to second in Current projection region by first state change
Corresponding direction of action during state.For example, if user's both hands are become by open mode in the horizontal direction turns to closure
During state, both hands are gradually mobile and close from relative position in the horizontal direction, and moving direction is horizontal direction, as corresponding
Operation direction.Certainly, the operation direction of operating body can also be along any axis direction (including x-axis, the y in three-dimensional coordinate
Axle, z-axis) or other directions, it is of the invention to be not specifically limited herein.
, can be using the solid space region between two operating bodies as corresponding with the first predetermined registration operation in the embodiment of the present invention
The first view field, the first project content corresponding to the region can be three-dimensional spatial distribution program stereoprojection shadow
Picture, i.e., the project content that user is marked by both hands in view field is defined as to the operation pair for changing progress projection mode dress
As.
For example, if the projection image that holographic projection system is currently shown in view field is landscape, the landscape includes
There is the stereopsis figure of the woods, flowers and plants, animal etc., can if user wants a trees therein being converted to two dimensional image
The both sides for three dimensional conforma region both hands being placed in where the trees, to choose its corresponding stereoprojection region.
Situation two：If first predetermined registration operation is switched to for control at least one operating body by second state
The operation of the first state, then S12 can specifically include procedure below：
First, it is corresponding in the Current projection region to obtain at least one operating body in said second condition
Initial operation coordinate；
Secondly, the initial operation coordinate corresponding plane coordinates region in the Current projection is determined；The plane
The first project content for including in coordinates regional in the first projection mode and being presented in two-dimensional space distribution；
Finally, the plane coordinates region is defined as the first view field corresponding with least one operating body.
, now, can will at least one because in the second state, at least one operating body and user's both hands are in closure state
The coordinate of individual operating body shared position in Current projection region is as initial operation coordinate.Specifically, the initial operation
When coordinate can be user's both hands closure, hand position coordinates shared in three-dimensional coordinate corresponding to view field.
And then plane coordinates region can be determined according to the initial operation coordinate of acquisition, the plane coordinates region can be
Refer to when user's both hands are in conjunction closed state and are placed in view field, the coordinates regional corresponding to palm area.If for example, user
Both hands closure is positioned in view field, then coordinates regional corresponding to palm can be used as plane coordinates region, and as first throws
Shadow zone domain.
S13：First predetermined registration operation is responded, by first project content with different from first projection mode
Second projection mode projects to first view field, obtains in the second space dimension different from first Spatial Dimension
It is distributed the second project content presented.
In the embodiment of the present invention, the second projection mode can have different spaces with the project content of the first projection mode
The projection mode of dimension.
Specifically, different for obtaining the mode of the first view field, S13 can be included but is not limited only to following two
Mode.
Mode one：If the first predetermined registration operation switches to the second state for control at least one operating body by first state
Operation, then can include procedure below：
First, first predetermined registration operation is responded, at least one operating body is obtained and is in second state when institute
Corresponding object run coordinate；
Secondly, the first operation planar corresponding with the object run coordinate in first view field is determined；
Finally, first project content is projected into institute with the second projection mode different from first projection mode
The first predetermined registration operation plane is stated, obtains the second project content presented in two-dimensional space distribution.
Wherein, object run coordinate can be that user's both hands turn to closed form in the first view field by open mode change
After state, palm corresponding coordinate in the first view field, the object run coordinate can be a coordinate set, and it is corresponding flat
Face can be used as object run plane.In practical application, when the conjunction of user's both hands is closed, the plane domain corresponding to palm is the first behaviour
Make the operating area of plane, i.e., above-mentioned plane coordinates region.
Further, the stereoprojection content that can be presented script in three-dimensional spatial distribution in the first view field is according to the
Two projection modes are mapped to the first operation planar, form the flat two dimensional image with being presented in two-dimensional space distribution, i.e., second throws
Shadow content.
For example, the stereoprojection content that the project content in Current projection region includes is a portrait and a house,
User wishes the part stereoprojection of portrait being converted to two-dimensional projection, then palm can be inserted to the portrait projection of projection respectively
The both sides of image, equipment identifies the double palm width of user by infrared sensor, and as user's palm closes up, the portrait contracts gradually
It is small.Last palm conjunction closes rear stereo portrait and is gradually converted to flat two-dimentional portrait presentation in front of the user, now the two-dimentional people
As being presented in two dimensional surface, user can delete the portrait, and other images or word etc. are shown on two dimensional surface.
Mode two：If the first predetermined registration operation is switched to the behaviour of first state at least one operating body of control by the second state
Make, then S13 there can be procedure below：
First, first predetermined registration operation is responded, is obtained in the first state, the institute in the Current projection region
Second terminates coordinate corresponding to stating the first termination coordinate corresponding to the first operating body and second operating body；
Secondly, it is determined that in the target direction described first terminate the first coordinate of coordinate and the initial operation coordinate away from
From, and the second termination coordinate and the second coordinate distance of the initial coordinate；Wherein, the target direction is perpendicular to institute
The direction of plane where stating plane coordinates region；
Finally, based on first coordinate distance and second coordinate distance, by first project content with described
First view field carries out space stretching as original position region on the target direction, obtains and is in three-dimensional spatial distribution
Existing the second project content corresponding with first project content.
Wherein, the first termination coordinate and the second termination coordinate can be that the both hands of user are drifted apart from being in by closure state
During open mode, distinguished by the infrared sensor in holographic projection system or camera detection both hands in Current projection region
Corresponding coordinate.
And target direction can refer to that at least one operating body carries out corresponding moving direction during the first predetermined registration operation, the mesh
Marking direction can be identical with foregoing operation direction.It should be noted that direction involved in the embodiment of the present invention can be
Finger corresponding direction in space in three-dimensional coordinate when carrying out predetermined registration operation.
Corresponding plane coordinates region is vertical when as a rule the moving direction is in closure state with palm.If for example,
User's both hands are closed and closed, and plane where palm is perpendicular to horizontal plane, when both hands are gradually opened, then can be moved both hands along horizontal
Direction is as target direction.
Certainly, in actual mechanical process, according to the difference of user's hand modes of emplacement in view field, target direction
It is not necessarily identical.For example, if the palm of user may be parallel to horizontal plane, moving direction can be the z-axis along three-dimensional coordinate
Direction；If for the palm of user to favour horizontal plane, moving direction also can respective change.
And then can by calculate displacement corresponding to the change in location of at least one operating body in the target direction come
It is determined that corresponding coordinate distance.
For example, if user's both hands move in three-dimensional coordinate along y-axis, when both hands palm, which closes, to be closed, corresponding initial operation
The coordinate value of coordinate on the y axis can be y0, after both hands are moved apart based on initial operation coordinate along y-axis, user's hand pair
First answered terminates the coordinate value y of coordinate on the y axis1, second terminate coordinate in y on coordinate value can be y2, so as to incite somebody to action
|y1–y0| it is defined as the first coordinate distance；Similarly, and incite somebody to action | y2–y0| it is defined as the second coordinate distance.
Can be specifically according to the first coordinate distance by the first project content when carrying out space stretching in practical application
And second coordinate distance stretched in the target direction, with formed three-dimensional spatial distribution present, with the first project content
Corresponding second project content.
For example, if the first coordinate distance corresponding to after the movement of user's left hand be 3cm, corresponding second coordinate after right hand moving
Distance is 5cm, then can gradually carry out the side for the first project content for being originally used for flat hologram with the movement of left hand
Stretching, formed 3-dimensional image, certain maximum tension can to 3cm, meanwhile, the opposite side of the first project content is with the movement of the right hand
Also gradually stretching extension, by originally flat image, gradually stretching expands to 3-dimensional image, is formed corresponding with the first project content
The stereoprojection image in the second projection mode, hereafter, user can also be by the second predetermined registration operation by the stereoprojection
Image is rotated or zoom etc..
Specifically, when the first project content is entered in the target direction according to the first coordinate distance and the second coordinate distance
Row stretching, when obtaining the second project content or holographic projection system will be distributed in two-dimensional space according to predetermined manner and be in
The first existing project content is converted to the second project content that is corresponding, being presented in three-dimensional spatial distribution.Predetermined manner therein
Can be including coordinate stretching distance etc. corresponding to image size, each coordinate points of project content, so as to detect that first is default
During operation, the first project content can be shown with different projection modes on different operation directions, so that user is considerable
Observe the projection image of different angle.
, can be according to due to when the first predetermined registration operation in detecting Current projection region be present in the embodiment of the present invention
