Control.
Eye Tracking Technique is to virtual reality system, particularly for the Portable virtual reality system based on smart mobile phone
For, it is a kind of more commonly used interactive means.Eye-controlling focus can be the position that system presets user's eyes, and
The position of eyes is represented using specific shapes such as such as crosses or dot, system is used by detecting to represent in use
The cross of person's eye position or the position of dot and its residence time realize the interaction of user and system.
Eye-controlling focus can also be by captured in real-time user's eye picture and by the analysis to figure so that it is determined that making
The position of user's sight, and based on this realization interaction.
But fact of case is using the Eye Tracking Technique accurate manipulation difficult to realize to virtual reality system.First,
The space and range of human eye are very limited, and most people is not frequently utilized that the movement of eyes comes in daily life
The external world is controlled.The daily habits of this and people are disagreed, and it is this to adapt to that user generally requires longer time
Controlling behavior.Secondly, there are problems for the accuracy of eyes positioning.Precise control and virtual reality system of the user to sight
The accuracy of accuracy and image procossing for the capture of user's sight all be there is a problem that certain.Therefore, sight is utilized
Tracer technique is adjusted parameter area that there is bigger difficulties.Especially the needs such as such as volume are accurately adjusted
This is particularly problematic for parameter.Further, what Eye Tracking Technique was relied on is the eye motion of user, is being needed to void
Quasi- reality system carries out frequently or in the case of accurate operation, it is easy to the tired and dizzy of user's eye be caused equal to be given birth to

In view of this, this application provides a kind of method according to the interaction of user's head action control virtual reality and being
System, to solve the problems, such as that current virtual reality system cannot be easy, quick and be accurately adjusted parameter area.
Fig. 1 show the schematic diagram that user wears virtual reality system, wherein being defined using user's head position as origin
O-xyz coordinate systems.Coordinate system of the following description with reference to figure 1.
Fig. 2, which is shown, to be interacted according to one embodiment of the application in reality environment, especially to parameter
The flow chart that range is adjusted.
In step 202, the running gear of virtual reality system, such as smart mobile phone enter under the excitation of user to ginseng
The adjustment modes of number range.
Parameter mentioned herein can be that volume, brightness, contrast, viewing progress, view size etc. are arranged with system
Or the relevant amount of operation.For example, user can be more than certain threshold time by watching the control key on screen attentively, or can lead to
The running gear for crossing sound excitation virtual reality system enters parameter area adjustment modes.Mode into adjustment modes can be very
It is more, however it is not limited to example recited herein, in virtual reality system it is existing carry out simple interactive means can by with
Carry out activating system and enters the pattern being adjusted to parameter area.
In step 204, after entering parameter area adjustment modes, virtual reality system running gear transports the head of user
It is dynamic to be detected.
The running gear of virtual reality system, such as smart mobile phone are generally provided with gyroscope, accelerometer, the whole world
Positioning system (GPS), and/or magnetometer, after smart mobile phone is worn on head by user by VR frames, smart mobile phone can be with
According to these sensor collections to data be inferred to the movement locus on the head of user.
It is selectable, in step 206, in order to improve the accuracy of manipulation, avoid the daily head movement of user and biography
Head movement up to instruction lumps together, running gear can to the move distance of user's head in particular directions and/or add
Speed is judged.Only the distance of the movement of user's head in this direction and/or acceleration are more than that certain threshold value is just true
It is the action with instructing meaning, being adjusted to parameter area to recognize.Otherwise, running gear can be by move distance and acceleration
The daily headwork that user does not have any instruction meaning is regarded as less than the action of threshold value.
In step 208, running gear moves pre- between parameter area adjustment according to the result and user's head of detection
Fixed correspondence, is adjusted correspondingly parameter area.
Fig. 3, which is shown, to be interacted according to another embodiment of the application in reality environment, especially to ginseng
The flow chart that number range is adjusted.Can also include the operation similar to step 202 in Fig. 2 or 206 in this method.
In step 302, running gear collects the displacement of the lines data before and after user's head moves in particular directions.
In step 304, running gear adjusts width according to the displacement of the lines of user's head in the specified direction with parameter area
Correspondence between degree is adjusted parameter area.
For example, in three-dimensional system of coordinate (o-xyz), running gear is only with user's head movement locus along the displacement of x-axis
Measure the reference as adjusting parameter range.And whether the track of user's head movement is parallel with x-axis, if in y-axis or z-axis
It is important, it is all unrelated with the adjustment of parameter area.It is of course also possible to point by user's head movement locus in y-axis or z-axis
Measure the foundation that is adjusted as parameter area, this be can according to the needs of user, apply the characteristics of and use environment change
's.
According to one embodiment, the displacement of the lines before and after user's head movement in the direction of the x axis is bigger, and running gear is with regard to corresponding
Carry out bigger adjustment to parameter area, such as the user's head displacement per 3cm in the direction of the x axis, then running gear is to ginseng
Number range such as volume, adjusts an amplitude such as 5dB；Or for watching progress, user's head is in the direction of the x axis per 3cm
Displacement can correspond to 5 minutes viewing progress adjustment etc..Certainly these correspondences numerically be can be according to user
Needs, application the characteristics of and application environment difference and change.
According to another embodiment, a series of predeterminated positions, example can be prestored in virtual reality system running gear
Such as using user's head initial position as origin o, can be set to respectively apart from origin 3cm, 6cm, 9cm etc. along x-axis preset
Position corresponds respectively to the adjustment amplitude to 5dB, 10dB, 15dB of such as volume.Certainly, between preset point and its corresponding
Amplitude between interval be not necessarily the only one, can be increasing or decreasing etc..When user head movement to just this
When a little preset positions, virtual reality system running gear can carry out parameter area the adjustment of corresponding amplitude.When the head of user
When portion moves to the position between these preset points, running gear can be according to default rule, such as according to user's head
Amplitude corresponding to a hithermost predeterminated position is adjusted parameter area.For example, when user's head is from origin
Displacement along x-axis is 7cm, then just being carried out to such as volume according to along adjustment amplitude of the x-axis corresponding to the positions origin 6cm
The adjustment of 10dB.
Further, running gear can distinguish the displacement of the lines in x-axis both forward and reverse directions, for distinguishing the increasing to parameter area
Big and reduction.For example, the positive displacement of the lines along x-axis corresponds to the increase to parameter area, the reversed displacement of the lines along x-axis corresponds to
In the reduction to parameter area.Embodying can be in specific applications, such as the case where needing to adjust video-see progress
Under, user's head can correspond to F.F. in the displacement of the lines of x-axis forward direction, correspond to the retrogressing of progress in the reversed displacement of the lines of x-axis.
Therefore, user can realize that such as F.F. retreats to final in succession with the direction of the control of continuous several times its head movement and distance
It accurately navigates to it and wants the video location of viewing.
Certainly, the correspondence of the displacement of the lines on above-mentioned specific direction and the amplitude of variation of parameter area can be a variety of more
Sample.For example, in order to which more specific difference increases and reduces, the increase of parameter area can be corresponded to for example in x-axis
Displacement of the lines, by the reduction of parameter area corresponding to the displacement of the lines in other directions, such as the displacement of the lines etc. in y-axis or z-axis.This
All it is the transformation belonged within the application protection domain.
Fig. 4, which is shown, to be interacted according to another embodiment of the application in reality environment, especially to ginseng
The flow chart that number range is adjusted.In this approach, can also include be similar to Fig. 2 in step 202 or 206 operation.
In step 402, running gear collects the front and back angular displacement data around specific direction of user's head movement.
In step 404, angular displacement of the running gear according to user's head around the specific direction adjusts amplitude with parameter area
Between correspondence parameter area is adjusted.
The running gear of current portable reality system, such as smart mobile phone, are generally provided with gyroscope or acceleration
Degree meter.Smart mobile phone can according to these sensor collections to data be inferred to the angular displacement of the head movement track of user
Amount.
In one embodiment, running gear can only with user's head movement locus around the angular displacement of y-axis or
Say the angle of rotation, the reference as adjusting parameter range.No matter whether the track of user's head movement exists around x-axis or z
The rotation of axis will not all have an impact the adjustment of parameter area.It is of course also possible to by user's head movement locus around x-axis or
The foundation that angular displacement in person's z-axis is adjusted as parameter area, this be can according to the characteristics of the needs of user, application and
Use environment changes.
According to one embodiment, angular displacement of the user's head movement locus on y-axis direction is bigger, and running gear is with regard to corresponding
Bigger adjustment is carried out to parameter area, such as user's head often rotates 10 degree on y-axis direction, then running gear is to parameter
Range, such as volume, adjustment amplitude can be such as 5dB；Or for watching progress, user's head is often revolved on y-axis direction
Turn 10 degree of viewing progress adjustments etc. that can correspond to 5 minutes.Certainly these correspondences numerically be can according to
The difference of the environment of the characteristics of needs at family, application and application and change.
According to another embodiment, a series of predeterminated positions, example can be prestored in virtual reality system running gear
Such as using user's head initial position as origin o, rotated around y-axis 10 degree, 20 degree and 30 degree etc. of point can be set to respectively it is pre-
If position, correspond respectively to the adjustment amplitude to 5dB, 10dB, 15dB of such as volume.Certainly, between preset point and its
Interval between corresponding amplitude is not necessarily the only one, can be increasing or decreasing etc..When the head movement of user is to just
When these good preset positions, virtual reality system running gear can carry out parameter area the adjustment of corresponding amplitude.Work as user
Head movement to position between these preset points when, running gear can be according to default rule, such as according to user
Amplitude corresponding to the hithermost predeterminated position in head is adjusted parameter area.For example, working as user's head from origin
The angular displacement rotated around y-axis of setting out is 22 degree, then just according to the adjustment amplitude rotated around y-axis corresponding to 30 degree of position to example
As volume carries out the adjustment of 10dB.If falling the point midway in two predeterminated positions just, it can utilize and for example round up
Rule correspond to corresponding adjustment amplitude.
Further, running gear can distinguish the angular displacement around y-axis clockwise and counterclockwise, for distinguishing to ginseng
The increase and reduction of number range.For example, the clockwise angular displacement around y-axis corresponds to the increase to parameter area, around the inverse of y-axis
The angular displacement of hour hands corresponds to the reduction to parameter area.Embodiment can be in specific applications, such as be regarded needing to adjust
In the case of frequency viewing progress, user's head can correspond to F.F. around the clockwise angular displacement of y-axis, counterclockwise around y-axis
Angular displacement corresponds to the retrogressing of progress.Therefore, user can with a sequence of F.F. in its head of the rotation of continuous several times or retreat to
It is final accurately to navigate to its video location for wanting to watch.
Certainly, the correspondence of the amplitude of variation of the angular displacement on above-mentioned specific direction and parameter area can be a variety of more
Sample.For example, in order to which more specific difference increases and reduces, the increase of parameter area can be corresponded to for example around y-axis
Angular displacement, by the reduction of parameter area corresponding to the angular displacement in other directions, such as the angular displacement etc. in x-axis or z-axis.This
All it is the transformation belonged within the application protection domain.
Using the above method, user can carry out repeated multiple times adjustment to parameter area, be more advantageous to raising and adjust
Whole accuracy.In addition, since the eyes that the above method is not required for user watch the display area of virtual reality system attentively always,
The of short duration participation for the user's sight that can arrange in pairs or groups, such as enter or exit parameter area adjustment modes etc., but it is not required for eye
Eyeball does prolonged lasting and precise motion.So, for the asthenopia for alleviating user, dizzy and relevant maloperation
All it is very helpful.
Under some applicable cases, user may need significantly to adjust the parameter area of virtual reality system
It is whole, however the distance of the permitted head movement of physical environment or the angle of rotation residing for user may be very limited.This
The side that parameter area is adjusted in virtual reality system following section provides some for the above situation applied
Method.
Fig. 5, which is shown, to be interacted according to the further embodiment of the application in reality environment, especially to ginseng
The flow chart that number range is adjusted.Certainly the operation that this method can also be including step 202 in such as Fig. 2 or 206.
In step 502, the running gear of virtual reality system detects the movement of user's head in particular directions.This
In the case of user's head move the size apart from length or rotational angle recede into the background.These certain headworks may be still
To belong to the headwork for instructing meaning for example, by the screening similar to step 106, rather than the head that user is daily
It is mobile.
In step 504, in response to user's head displacement of the lines each time in particular directions or around the angle of specific direction position
It moves, the adjustment of predetermined amplitude is carried out to the parameter area.
In this embodiment, user's head moving or rotating each time corresponding to parameter area in particular directions
Predetermined amplitude adjustment.For example, in the pattern being adjusted to video progress, the head of user is along each of x-axis forward direction
Mobile corresponding video pushes ahead 3 minutes progresses；Or the head of user around the corresponding video of the clockwise each rotation of x-axis to
It is pushed forward the progress into 3 minutes.
User can move along specific direction or rotate step-by-step movement of the head realization to parameter area by continuous several times
Adjustment.For example, the head of user can constantly return to close to initial position and then open again after each mobile or rotation
The movement begun next time.So, the interactive operation being adjusted to parameter area in virtual reality system is for physics
The requirement of space and user's head motion amplitude can be greatly reduced.
Selectable, in step 506, according to testing result, such as it is shifting along specific direction that user's head moves for the first time
Rotation dynamic or around specific direction, or according to the instruction of user, running gear enters the submodule unidirectionally adjusted to parameter area
Formula, running gear are ignored user's head and are moved twice along the specific direction or rotated around specific direction during wears adjacent
The slotting movement or rotation in other directions, until running gear exiting of detecting that user sends out is adjusted parameter area
The instruction of pattern.
For example, in scheduled correspondence, user's head being moved or being rotated clockwise pair around x-axis along x-axis is positive
Cope with the increase of parameter area, user's head being moved or being rotated counterclockwise to reply parameter area around x-axis along x-axis is reversed
Reduce.When user continuously moves along x-axis forward direction three times or rotates clockwise head around x-axis, running gear is accordingly by parameter model
It encloses and increases three amplitudes.According to one embodiment, the mobile or rotation positive three times of user's head is intermediate may to be mingled with one
It is secondary either reversely or around the head counterclockwise of x-axis to move or rotate along x-axis twice.But it if will be interspersed in three times just
To between movement or rotation reverse movement or rotation take into account and correspond to subtract parameter area according to preset rules
If small, the intention generation that will increase parameter area originally with user conflicts or reverse effect.
Therefore, according to one embodiment of the application, according to testing result (such as the movement for the first time of user's head is along x
Axis forward direction is mobile or if the rotating clockwise of x-axis) or user instruction, running gear, which enters, for example increases parameter area
Subpattern, the running gear of virtual reality system can't by user's head for example three times along the movement of x-axis forward direction or
Three times around x-axis rotate clockwise between intert it is reversed or move or rotate around x-axis head counterclockwise and be considered have along x-axis
The head movement for having instruction meaning, to ensure while realizing that head is repeatedly moved to parameter area progress step-by-step movement adjustment
Avoid the unnecessary interference adjusted to parameter area.
Correspondingly, in this embodiment, if according to testing result, such as the movement for the first time of user's head is along x-axis
Reversed movement or around x-axis rotation counterclockwise or according to user instruction, running gear can reduce into such as parameter area
Subpattern, running gear can ignore user's head and for example move backward three times along x-axis or three times between x-axis rotates counterclockwise
It is interspersed any positive or move or rotate around the clockwise head of x-axis along x-axis.
It can stop after running gear detects the instruction for exiting parameter area adjustment modes that user sends out in step 508
Only parameter area is adjusted.It, can be by exiting ginseng if user wants to carry out other kinds of adjustment to parameter area
Then number adjustment modes reenter the adjustment modes of parameter area, such as first pass through the increase to parameter area for several times, then
Adjustment modes are exited, then re-enter adjustment modes carry out the reduction to parameter area for several times.
Further, it can be realized by the head state of user to exit parameter adjustment extent directive, such as user
Head stop motion 10s.It is of course also possible to be to watch or leave specific region certain time attentively by eyes of user to realize
's.The means interacted in virtual reality system may serve to as the finger for entering or exiting parameter area adjustment modes
It enables.
By the above method, when user operates virtual reality system under the limited application environment of physical space,
The accurate adjustment to parameter area may be implemented.In addition, using the above method, running gear exists it is only necessary to detect user's head
Movement on specific direction or number of revolutions, and no longer need to judge the distance or rotation that user's head moves in particular directions
Angle, reduce the load of running gear, interactive efficiency also can higher.From user experience, user also need not be deliberately
Control head movement distance or angle, it is thus only necessary to controlled motion or the number of rotation, operation it is more easy to be laborsaving.
In some specific virtual reality applications, it is understood that there may be substantially quickly accurately adjusted to parameter area progress
It needs.In this case, the adjustment of single amplitude, for a user may or inadequate convenient and efficient.Therefore the application
Another embodiment presented below, the demand for the above-mentioned type for user.
Fig. 6 is shown moves the side being adjusted to parameter area according to the application one embodiment based on user's head
The flow chart of method.
In step 602, the running gear of virtual reality system enters the adjustment mould to parameter area under the excitation of user
Formula.
In step 604, running gear is provided a user carries out rough and two selections of intense adjustment to parameter area.
In step 606, running gear receives the selection instruction of user.
If user has selected to adjust parameter area roughly, in step 608, running gear detection user's head exists
The displacement of the lines of specific direction or angular displacement, and according to user's head displacement of the lines in this direction or angular displacement and parameter area
Scheduled correspondence adjusts roughly relationship and is adjusted to parameter area between adjustment.This correspondence can have relatively
Big ratio, for example, user's head often moves 3cm or often rotates 10 degree around x-axis along the x-axis direction, corresponding video progress is to being pushed forward
Into or backward fall back 10 minutes.It is of course also possible in conjunction with front method in step-by-step movement Regulation mechanism, when user's head is along x
Axis is often mobile primary or often rotate around x-axis primary, no matter moves or rotation amplitude is much, correspondence video progress push ahead or to
It falls back 10 minutes afterwards.This correspondence is the parameter area that can be adjusted as needed, the demand of user and running equipment
Configuration it is different and different.
If user has selected to carry out carrying out intense adjustment to parameter area, in step 610, running gear detection account
Displacement of the lines or angular displacement of the portion in specific direction, and according to scheduled user's head displacement of the lines in this direction or angular displacement
Intense adjustment correspondence between being adjusted with parameter area is adjusted parameter area.This correspondence can have phase
To smaller ratio, for example, user's head often moves 3cm or often rotates 10 degree around x-axis along the x-axis direction, corresponding video progress
It pushes ahead or falls back backward 1 minute.It is of course also possible in conjunction with front method in step-by-step movement Regulation mechanism, when with account
Portion often moves primary along x-axis or often rotate around x-axis primary, no matter moves or rotation amplitude is much, and correspondence video progress is to being pushed forward
Into or backward fall back 1 minute.This correspondence is the parameter area that can be adjusted as needed, the demand of user and operation
The configuration of equipment it is different and different.
Rough and fine two kinds of adjustment modes have been only discriminated between in above-mentioned example, can also have been carried out more according to different needs
It is further to distinguish, but belong to the variation within the scope of the application.
